PER CURIAM

      This case concerns water leaks in a residential unit within a high-rise

condominium building in Cliffside Park known as Winston Towers 200. The thirty-

one-story building, one of two towers, was constructed in 1973 on the grounds of

the former Palisades Amusement Park.

      The complex is overseen by a condominium association, Winston Towers 200

Association, Inc. ("the association"). The association engages a separate firm, RCP

Management Company ("RCP"), to manage the premises.

                                                                          A-2742-18T1
                                        3
      Plaintiffs Steven Makai and Becky Chacko bought Unit 1720 within Winston

Towers in 2013. After they moved in, plaintiffs started to renovate their master

bathroom. Their bathroom contractor noticed mold behind the walls, so plaintiffs

retained a mold remediation expert, Charles Schwartz. Schwartz substantially traced

the mold to water emanating from Unit 1820 directly above plaintiffs' unit. That

upstairs unit is owned by Ramesh Mehta, who had been renovating his own

bathroom.

      Mehta’s contractor, J&Y Construction Company, attempted to repair the

leaks, but mold spots returned in Unit 1720. Concerned about the mold spots for

health reasons, Makai temporarily vacated the premises until the mold and water

problem was finally abated. Makai claims he lost income because he was not able

to work from home during the time the mold persisted.

      Plaintiffs sued Mehta, J&Y, the condominium association, its management

company RCP, and various other parties for negligence in failing to act reasonably

to prevent the mold and water infiltration. The association named its insurance

broker, BHB Insurance Services and claims manager Barbara Lombardi, as third-

                                                                          A-2742-18T1
                                        4
party defendants for failing to procure mold coverage.1         Extensive discovery

overseen by the Law Division ensued.

      Eventually plaintiffs settled with Mehta and J&Y for an undisclosed sum.

They are now pursuing the association and RCP for additional damages.

      Plaintiffs argue the association had a duty to warn them about latent mold and

water leakage behind the walls. They contend such a duty is consistent with this

court's opinion in Siddons v. Cook, 382 N.J. Super. 1 (App. Div. 2005) (holding that

a condominium association, based on its knowledge of widespread problems, had a

duty to warn unit owners that dishwasher hoses in their units were prone to leaks).

      To support their causation argument that the water infiltrated their unit from

common areas within the association's purview, plaintiffs rely upon the report of

their expert, Schwartz. In that regard, they note Schwartz's hypothesis that the leaks

may be attributed, at least in part, to long-standing "historical" water problems

within the tower. Plaintiffs also attempt to rely upon expert opinions of Robert

Strode, an industrial hygienist who had originally been retained by Mehta. In his

expert report prepared for Mehta before the settlement, Strode opined the water leaks

in Unit 1720 predominantly did not come from Mehta's unit above.

1
  Because of the trial court's dismissal of claims against the association, the
court never needed to address the viability of those coverage claims.
                                                                             A-2742-18T1
                                          5
      The trial court granted the association and RCP summary judgment. Among

other things, the court found plaintiffs lacked what it deemed to be a necessary expert

on building management practices. The court also found plaintiffs had no expert

showing, with an appropriate evidential foundation, that the cause of the leaks to

Unit 1720 stemmed from any common areas in the building.

      Although it did not need to reach damages issues, the court dismissed

plaintiffs’ claims for lost income and bodily injury damages. It imposed those

sanctions upon plaintiffs for failure to cooperate in discovery in scheduling a

physician's deposition and obtaining requested tax records.

      Plaintiffs now appeal, mainly arguing that the trial court erred in concluding

their claims against the association and RCP lack sufficient expert support. They

further argue the court misapplied its discretion in imposing severe discovery

sanctions against them on the damages issues.

      For the reasons to follow, we affirm the summary judgment order. Although

we disagree with certain aspects of the trial court's analysis, we likewise conclude

plaintiffs have not marshalled sufficient expert support to establish the leaks to their

unit originated in common areas. Consequently, plaintiffs have no viable claims

against the association and RCP. Because of that failure to establish liability, we

need not grant any relief as to the damages-related discovery sanctions.

                                                                               A-2742-18T1
                                           6
                                        I.

      Familiar principles guide our analysis of the trial court's summary

judgment order. Summary judgment "must be granted if 'the pleadings,

depositions, answers to interrogatories and admissions on file, together with t he

affidavits, if any, show that there is no genuine issue as to any material fact

challenged and that the moving party is entitled to a judgment or order as a

matter of law.'" Town of Kearny v. Brandt, 214 N.J. 76, 91 (2013) (quoting R.

4:46-2(c)). The court must decide whether "the competent evidential materials

presented, when viewed in the light most favorable to the non-moving party, are

sufficient to permit a rational factfinder to resolve the alleged disputed issue in

favor of the non-moving party." Brill v. Guardian Life Ins. Co., 142 N.J. 520,

540 (1995). We review de novo the grant or denial of a motion for summary

judgment. Steinberg v. Sahara Sam's Oasis, LLC, 226 N.J. 344, 349-50 (2016).

                                        A.

      To perform our review, we first consider the legal framework for

plaintiff's claims against the association and its management firm, RCP.

      A condominium association is composed of unit owners, N.J.S.A. 46:8B-

9, -12, -12.1, and "is responsible for the administration and management of the

condominium." Siddons, 382 N.J. Super. at 6 (App. Div. 2005) (citing N.J.S.A.

                                                                          A-2742-18T1
                                        7
46:8B-8, -12). An association's operations are informed by the Condominium

Act, N.J.S.A. 46:8B-1 to -38, as well as the contents of the master deed and the

condominium by-laws. Siddons, 382 N.J. Super. at 6 (citing N.J.S.A. 46:8B-13,

-14, -15).

      By statute, a condominium association is responsible for the

"maintenance, repair or replacement of any common elements therein or

accessible therefrom or for making emergency repairs necessary to prevent

damage to common elements or to any other unit or units." N.J.S.A. 46:8B-

15(b) (emphasis added). A unit owner nevertheless remains liable "for injuries

or damages resulting from an accident in his own unit in the same manner and

the same extent as the owner of any other real estate." N.J.S.A. 46:8B-16(c)

(emphasis added).

      Here, the By-Laws and Master Deed for Winston Towers 200 reiterate this

important distinction between common areas and private unit areas. The overall

administration, management, maintenance, repair, and operation of the Winston

Towers 200 building is governed by the By-Laws of the association. Section 3

of the By-Laws, which governs damage to the property, provides:

             If the damage is only to those parts of one Apartment
             Unit for which the responsibilities of maintenance and
             repair are those of the Unit Owner, then the Unit Owner

                                                                        A-2742-18T1
                                       8
            shall be responsible for reconstruction and repair after
            casualty.

            [(Emphasis added).]

      The property rights of the association and the owner of each residential unit

within Winston Towers 200 are further governed by the Master Deed. The Master

Deed defines the term "Apartment Unit" as follows:

            (d) "Apartment Unit" shall mean a part of the Building
            designed and intended for independent use as a private
            dwelling and shall consist of the interior walls and
            partitions which are contained within the private
            dwelling and shall also consist of the inner decorated
            and/or finished surfaces of the perimeter walls, floors
            and ceilings, including dri-wall [sic], paint, wallpaper,
            etc. contained in the dwelling, as shown on the Survey,
            but shall not mean any part of the Common Elements
            situated within the Apartment Units.

            [(Emphasis added).]

      The Master Deed defines "Common Elements" as follows:

            (f) "Common Elements" shall consist of all parts of the
            Property other than the Apartment Units, including the
            items set forth in the Condominium Act, and the rights
            of the Association pursuant to the Additional
            Recreational Facilities Agreement annexed hereto and
            made a part hereof as Exhibit A, subject to the terms,
            provisions, conditions and charges thereunder.

            [(Emphasis added).]

                                                                          A-2742-18T1
                                        9
      The Master Deed provides that each unit owner "shall furnish and be

responsible for, at his own expense, all of the maintenance, repairs and replacements

within his own Apartment Unit," which include "the refrigerators, ranges and other

kitchen appliances and lighting fixtures and other electrical appliances and plumbing

fixtures . . . ." In contrast, the Master Deed provides that the maintenance, repairs

and replacements to be made to the Common Elements "shall be furnished by the

Association as part of the common Expenses."

      In addition, a fellow unit owner—such as Mehta here—may be liable for

causing damage to either (1) common areas or (2) the apartments of other unit

owners in the building. As the Master Deed specifies:

             If, due to the negligent act or omission of a Unit Owner,
             or of a member of his family or household pet or of a
             guest or other authorized occupant or visitor of such
             Unit Owner, damage shall be caused to the Common
             Elements or to an Apartment Unit or Apartment Units
             owned by others, or maintenance, repairs, or
             replacements shall be required which would otherwise
             be at the Common Expense, then such Unit Owner shall
             pay for such damage and such maintenance, repairs and
             replacements to the Common Elements or the
             Apartment Units . . . .

             [(Emphasis added).]

                                                                            A-2742-18T1
                                        10
                                     B.

      The functions of the association in the present case were substantially

delegated to RCP, which the association hired in January 2008 to serve as its

Managing Agent. A management agreement between RCP and the association

defined RCP’s duties to the association and its members. That agreement delineates

RCP’s obligations to unit owners as follows:

            The Managing Agent shall maintain businesslike
            relations with condominium unit owners and with all
            tenants and residents of the Condominium, all of whose
            service requests and complaints shall be received,
            considered, acted upon, and recorded systematically,
            showing the action taken with respect to each. Requests
            deemed by the Managing Agent to be unreasonable,
            outside the scope of its responsibilities or those of the
            Association, or those of a serious nature, shall, after
            thorough investigation, be reported to the Board with
            appropriate recommendations.

            [(Emphasis added).]

      Regardless of any contract it may have with a management firm, the

governing body of a condominium association "has a fiduciary obligation to the

unit owners 'similar to that of a corporate board to its shareholders.'" Siddons,

382 N.J. Super. at 7 (quoting Kim v. Flagship Condo. Owners Ass'n, 327 N.J.

Super. 544, 550 (App. Div. 2000)). Condominium association board members

are required to "act reasonably and in good faith in carrying out their duties."

                                                                         A-2742-18T1
                                       11
Jennings v. Borough of Highlands, 418 N.J. Super. 405, 421 (App. Div. 2011)

(quoting Papalexiou v. Tower West Condo., 167 N.J. Super. 516, 527 (Ch. Div.

1979)).

      To sustain a cause of action for negligence against a condominium

association, like any other negligence claim, "a plaintiff must establish four

elements: '(1) a duty of care, (2) a breach of that duty, (3) proximate cause, and

(4) actual damages.'" Townsend v. Pierre, 221 N.J. 36, 51 (2015) (quoting Polzo

v. Cnty. of Essex, 196 N.J. 569, 584 (2008)).

      "Whether a duty exists is a matter of law, to be decided by the court, not

the factfinder." Siddons, 382 N.J. Super. at 8 (citing Rogers v. Bree, 329 N.J.

Super. 197, 201 (App. Div. 2000)). When determining the existence of a duty,

courts consider fairness, public policy, and foreseeability of injury to others

from a defendant’s conduct. Snyder v. Am. Ass’n of Blood Banks, 144 N.J.

269, 292 (1996).

      In Siddons, the key case plaintiffs rest upon in alleging the association's

liability, we illustrated how these concepts of duty and negligence operate.

There, the plaintiff’s condominium unit was flooded by water from a broken

dishwasher hose in another unit. Id. at 5. The condominium association was

aware that similar hoses had previously broken and caused flooding in other

                                                                         A-2742-18T1
                                       12
units. Ibid. The trial court granted the association’s summary judgment motion,

finding it owed no duty to warn the plaintiff about the potential flooding hazard.

Ibid. We reversed.

      Although the plaintiff in Siddons conceded that the dishwasher was not a

common area the association was responsible for maintaining, we reasoned that

"under some circumstances the knowledge of a dangerous condition, regardless

of control over that condition, may impose upon a person a duty to warn third

parties of the danger. Those circumstances exist here." Id. at 10. Before the

flooding incident in Siddons that damaged the plaintiff’s unit, the association

had been notified on "at least three occasions that the dishwasher hoses that had

been installed by the original developer caused flooding to other condominium

units." Id. at 11. This information was not known by most of the unit owners.

In that particular factual setting, we held it would not have been unreasonably

burdensome for the association to have a duty to notify the unit owners about

the hazard. Ibid. Consequently, we vacated summary judgment in Siddons and

remanded the matter for a trial. Id. at 14.

      Tracking these principles, plaintiffs contend the association had a

fiduciary duty to "preserve and protect the common elements and areas for the

benefit of all of its members," and failed to do so here. According to plaintiffs,

                                                                         A-2742-18T1
                                       13
two expert opinions concluded that water infiltration into their unit came from

the common elements of the building, which the association and RCP are

responsible for by statute and contractual agreement.

      Plaintiffs cite in this regard to a history of water infiltration in the building

dating back to as early as 1998, fifteen years before they moved into the unit,

where there was leaking associated with the curtain wall windows in unspecified

other units. Plaintiffs also point to water intrusion in the building from a water

main leak during boiler replacement work in 2013, as well as previous mold

testing between 2009 and 2011 that was a "repeated" topic of discussion at board

meetings between 2010 and 2012.

                                         C.

      In the first part of its summary judgment analysis, the trial court ruled that

plaintiffs could not pursue their negligence claims against the association and

RCP because they did not retain an expert witness on condominium association

management practices. Under the circumstances presented here, we disagree

that such an expert is vital to support these negligence claims alleging

unreasonable conduct or lack of action.

      As a general matter of evidence law, N.J.R.E. 702 provides that "[i]f

scientific, technical, or other specialized knowledge will assist the trier of fact

                                                                              A-2742-18T1
                                         14
to understand the evidence or to determine a fact in issue, a witness qualified as

an expert by knowledge, skill, experience, training, or education may testify

thereto in the form of an opinion or otherwise." (Emphasis added).

      Expert testimony "should not be permitted unless it concerns a subject

matter that is 'so distinctively related to some science, profession, business or

occupation as to be beyond the ken of the average layman.'" Jacobs v. Jersey

Cent. Power & Light Co., 452 N.J. Super. 494, 505 (App. Div. 2017) (emphasis

added) (quoting Biunno, Weissbard & Zegas, Current N.J. Rules of Evidence,

cmt. 1 on N.J.R.E. 702 (2017)). Expert testimony is not necessary when the jury

can understand the concepts in a case "utilizing common judgment and

experience." Ibid. (quoting Campbell v. Hastings, 348 N.J. Super. 264, 270

(App. Div. 2002)); see also Mayer v. Once Upon A Rose, Inc., 429 N.J. Super.

365 (App. Div. 2013) (holding that an expert to opine on the physical properties

of glass was not required to support plaintiff's claim that a defendant negligently

held a glass vase and caused it to shatter).

      By contrast, "expert testimony is required when 'a subject is so esoteric

that jurors of common judgment and experience cannot form a valid

conclusion.'"   Hopkins v. Fox & Lazo Realtors, 132 N.J. 426, 450 (1993)

(quoting Wyatt by Caldwell v. Wyatt, N.J. Super. 580, 591 (App. Div. 1987));

                                                                          A-2742-18T1

Div. 2012) (requiring a qualified expert to opine on esoteric issues involving a

complex instrumentality to determine why car engine seized).

      In Jacobs, 452 N.J. Super. at 497, a negligence case, we ruled that the

plaintiff was not required to retain an expert to establish the standard of care of

a public utility company when the plaintiff fell in a hole in the ground left by

the utility for two months after performing electrical repairs. We rejected the

defendant’s argument that a jury could not determine without an expert whether

its actions were negligent, because as a public utility company it was heavily

regulated by the State. Id. at 506. We reasoned, "[a]lthough electrical power is

undoubtedly a complex and technical subject matter that often would call for

expert insight, [the] plaintiff in this case was not harmed by an electrical shock

or surge. She simply fell into . . . a hole in the ground, a hole which the jurors

reasonably found to have been left unattended too long." Id. at 508 (emphasis

added). The jury was readily capable of determining without expert assistance

whether the utility company acted negligently by leaving a hole in the ground

for two months with no durable warning signs on the ground by the plaintiff’s

home. Id. at 507. A basic standard of reasonable care was sufficient to guide

the jurors. Ibid.

                                                                          A-2742-18T1
                                       16
      Here, that same basic standard of reasonableness likewise could be

applied by jurors to defendants' conduct in light of their common judgment and

experience. If, as plaintiffs allege, the leaks into their unit were caused by water

infiltration from common areas, and the association and RCP had reason to be

aware of such persisting hazards, the jurors would be capable of evaluating

whether those defendants were unreasonable in failing to do anything about the

problem. It is not an "esoteric" question.

      In fact, there is no indication in Siddons that the plaintiff in that case

retained an expert on condominium management practices. Nor did our opinion

in Siddons say that such an expert was required to show the association had been

unreasonable. We therefore part company with the trial court in its declaration

that such an expert was required here. To be sure, plaintiff's case might have

been strengthened by calling such an expert, but one was not absolutely

necessary.

                                        D.

      That said, the expert deficiency that does sink plaintiffs here concerns not

proving breach of a duty, but causation. We agree with the trial court that

plaintiffs failed to establish, with appropriate expert opinion, that the damage in

                                                                           A-2742-18T1
                                        17
their unit was caused by water leaks from common areas. Plaintiffs' reliance on

the expert reports of Strode and Schwartz is unavailing, for several reasons.

      We begin with Strode.        As we have noted, Strode was retained by

defendant Mehta in an effort to try to show the water and mold in plaintiffs' unit

was not caused, or substantially caused, by water leaking from Mehta's upstairs

unit. Strode is a certified industrial hygienist "with a background in evaluating

the workplace and environment for potential hazards with regard to work

practices, measuring and evaluating exposures to various substances, and

determining and controlling the nature and extent of health risks in occupational

settings." In his expert report, Strode states he is familiar with "the evolution of

knowledge with respect to fungi (aka mold) in the field of industrial hygiene."

He is not an engineer.

      Strode concluded in his report that "[a]lthough Unit 1820 has also had

Property-related water intrusions over the years, there was no indication that any

water originating from Unit 1820 had entered Unit 1720 prior to or after

September 2014, when it was alleged that water originated from the master

bedroom shower in Unit 1820 dripped into Unit 1720 during the remediation

activities [in Unit 1720]."    His report further noted that "[a]lthough there

appeared to be some historical leaking associated with the curtain wall windows

                                                                           A-2742-18T1
                                        18
in Unit 1720, it did not appear that Mr. Makai, Ms. Chacko, or EASI requested

or performed any investigation or remediation under or around the exterior wall

where the windows were located." Along those lines, "[t]he Association board

meeting documents . . . support the presence of historical curtain wall window

leaks [in the building] and that consultants were hired as early as 1998 to

investigate the cause of the leaks."

      Strode further opined in his report "[t]he water intrusion, if any,

originating in Unit 1820 would have been de minimis and insufficient to have

been a substantial factor in the water intrusion and/or potential fungal growth in

the interstitial spaces of the Unit 1720 walls . . . ." Instead, Strode stated "Unit

1720 apparently experienced numerous long-standing historical water intrusion

events and at least one significant water intrusion event associated with a water

main leak during boiler replacement work in 2013." He added, "[t]he conditions

observed in the interstitial spaces during invasive investigation and remediation

. . . indicate that long-standing and/or significant water intrusion events were

the cause of the fungal growth in these areas."

      As a threshold procedural question, we agree with the trial court that

plaintiffs did not have the right to call Strode as their own expert witness after

they consummated a settlement with Mehta. That is because the deadline for

                                                                           A-2742-18T1
                                        19
plaintiffs to designate additional expert witnesses under the court's case

management orders had expired more than three months earlier.

      The pertinent chronology is as follows. On September 28, 2017 the trial

court ordered that "the discovery end date [("DED")] in this matter is January

29, 2018."   About a month later, on October 30, 2017, the court issued a

superseding management order requiring plaintiffs to serve all expert reports by

December 17, 2017. The court thereafter entered an order on December 15,

2017 extending the DED to May 1, 2018.

      Plaintiffs received a further extension of time for their experts on January

5, 2018, when the court issued an order mandating that "plaintiff[s] shall

exchange expert reports." On April 13, 2018, the court issued another extension

order, specifying "that defendants shall serve any and all expert reports, in

response to any expert report timely served by plaintiffs by February 16, 2018,

on or before June 1, 2018." (Emphasis added). In a fifth case management order

issued on June 11, 2018, the court ordered that "in the event that any defendant

or third-party defendant should timely serve an expert report, between July 2,

2018 and August 1, 2018, that . . . [the parties] shall have until September 1,

2018 to serve an expert report responding to that defendant or third -party

defendant's report."

                                                                         A-2742-18T1
                                      20
      In their earlier answers to interrogatories, plaintiffs identified Schwartz,

their mold remediation consultant, as an expert witness on liability. Plaintiffs

also reserved the right to supplement their response as to which experts they

intended to rely upon at trial.

      On May 1, 2018, plaintiffs' counsel wrote a letter to counsel for the

Association, RCP, and BHB, announcing that plaintiffs "reserve[d] the right to

call Robert D. Strod[e] as an expert at the time of trial in this matter," and

accordingly "amend[ed] answers to interrogatories to include same." Notably,

plaintiffs did not tender an amended report from Strode. Instead, they simply

relied on the report he had originally prepared for Mehta in fending off plaintiffs'

claims of Mehta's responsibility.

      During the oral argument on the summary judgment motions, the trial

court disallowed plaintiffs from using Strode as their own expert, under a

premise that plaintiffs had not retained him. We are not sure if that premise is

correct. Plaintiffs were not required to present to the court a retention letter or

other documentation confirming that Strode had agreed to serve as their expert

and the terms of that retention.

      We will presume that the May 1 letter from plaintiffs' counsel was based

upon a good faith representation that Strode had agreed to testify for plaintiffs.

                                                                           A-2742-18T1
                                        21
The problem, as we have noted, is that the deadline for plaintiff to designate

additional expert witnesses had already lapsed in February, after multiple

extensions.   The trial court is afforded wide latitude in managing pretrial

discovery. Abtrax Pharms., Inc. v. Elkins-Sinn, Inc., 139 N.J. 499, 513 (1995).

In order for that oversight to be successful, the parties must adhere to the

deadlines specified in case management orders. Appellate courts generally will

not interfere with discovery and pretrial case management rulings unless it is

demonstrated that the trial court abused its discretion. Id. at 517.

      Given the chronology here, we are unpersuaded the trial court abused its

discretion in ruling that plaintiffs could not rely on Strode as their own expert.

It appears that plaintiffs originally targeted their efforts in this case heavily

against Mehta, arguing that water had leaked into their unit from Mehta's due to

his renovation activities. Strode's expert report was generated as part of Mehta's

defense of those allegations, and plaintiffs' original liability expert Schwartz

apparently did not amend his report to address any of Strode's opinions.

      It was not until after plaintiffs achieved a settlement with Mehta did they

pivot, in essence, their liability focus to the association and RCP. Their adoption

of Strode's report as part of that late shift was after the court's specified deadline,

and hence too late.

                                                                              A-2742-18T1
                                         22
      We are aware that Rule 4:17-7 provides that except as otherwise provided

by Rule 4:17-4(e), "if a party who has furnished answers to interrogatories

thereafter obtains information that renders such answers incomplete or

inaccurate, amended answers shall be served not later than 20 days prior to the

end of the discovery period, as fixed by the track assignment or subsequent

order." This provision did not entitle plaintiffs to disregard the February 2018

deadline for their expert reports and belatedly expand their expert designations

in May 2018 without the court's permission.

      We are mindful that defendants had already received Strode's report from

Mehta's counsel and would not have been surprised by his opinions.

Nonetheless, the late designation of Strode as part of plaintiffs' case -in-chief

was never sanctioned by the trial court, and we will not interfere with that case

management decision.

      Even, assuming, for the sake of discussion, we were to reverse the trial

court's procedural ruling as to Strode, the content of his report and his

qualifications and methodology fall short in supporting plaintiffs on the critical

issue of causation. These deficiencies likewise pertain to plaintiffs' expert

                                                                         A-2742-18T1
                                       23
Schwartz, whose opinions on causation the trial court expressly and soundly

rejected, for the reasons we now explore. 2

        Schwartz has been certified by the American Council for Accredited

Certification as a microbial consultant, as well as an indoor environmental

consultant, indoor air quality consultant, and microbial remediation supervisor.

Like Strode, Schwartz is not an engineer.

        Plaintiffs initially retained Schwartz to take air samples of their unit.

Schwartz inspected the unit in July 2014. He found evidence of mold on the

surface of the inside of the wall cavity between plaintiffs' hall bathroom and the

common-area hallway. He also detected mold spores "in low concentrations" in

the master bedroom and master bathroom. 3

        During their investigation of the source of the water infiltration, building

maintenance staff located an active leak in the wall of the master bath of Unit

1720, which they concluded was likely causing water to flow through the wall

of plaintiffs' bathroom into the wall space next to it. A mold remediation project

thereafter was undertaken in August 2014.

2
  Our discussion is confined to the contents of the liability experts' reports, as
there were apparently no expert depositions taken.
3
    The record on appeal does not contain a copy of the mold test report.
                                                                            A-2742-18T1
                                        24
        In September 2014, after plaintiffs' contractor had gutted both bathrooms,

it discovered water dripping through an opening in the slab between Unit 1720

and the unit above, Unit 1820. Chacko reported this new leak to RCP's office.

The leak was identified immediately above the space between the common-area

hallway and the hall bathroom of Unit 1720, which adjoins the wall space

between the hall bathroom and the master bathroom. Building maintenance staff

suspected the water in Unit 1720 was coming from a bathroom upstairs in Unit

1820.

        The maintenance staff contacted Mehta and obtained his cooperation in

conducting a test to confirm that his shower was the source of the water

infiltration in Unit 1720. The workers opened up the wall outside of Unit 1820

in order to pinpoint the source of the leak into Unit 1720. They concluded the

leak into Unit 1720 was coming from Unit 1820. Accordingly, repairs to the

upstairs unit were conducted, and the reconstruction and remediation of

plaintiffs' unit were completed.

        In October 2015, Schwartz's firm issued a post mold remediation

clearance report, confirming there was no more evidence of mold in Unit 1720.

However, Makai asked the firm to return to look for "any other mold issues."

Schwartz's company did so in November 2015 and found moisture in the floor

                                                                         A-2742-18T1
                                        25
in a hallway and in two rooms, as well as evidence of water damage on a wall

near the kitchen exhaust shaft. These findings indicated the initial repairs and

remediation had been inadequate.

      Schwartz recommended further mold remediation, which was performed

by the same contractor who had conducted the first remediation project.

Thereafter, Schwartz's firm did further mold tests and concluded that air

throughout plaintiffs' unit now "met clearance criteria."

      Schwartz issued an expert report in connection with this litigation in

February 2018. Among other things, his report concluded that "our moisture

and assessment services identified several separate mold growth impacted areas

in apartment 1720 which were caused by historical building system leaks pre-

existing to and not caused by the residents of apartment 1720, Mr. Makai and

Mrs. Chacko."

      The trial court found such conclusory assertions to be inadequate to

support plaintiffs' causation arguments against the association and RCP.

Accordingly, the court dismissed plaintiffs' claims for lack of competent expert

proof of causation.

      On appeal, defendants echo the court's reasoning.       They argue that

Schwartz, a mold specialist who is not an engineer, lacks the qualifications to

                                                                       A-2742-18T1
                                      26
attribute the cause of the water damage in plaintiffs' unit to systemic water

infiltration in this massive building. They further contend Schwartz's attribution

to such systemic causes emanating from common areas is an inadmissible "net

opinion," noting that he did not perform testing with a proper methodology that

could determine such causation. We agree.

      A fundamental element of any negligence case is proximate causation.

Rappaport v. Nichols, 31 N.J. 188, 203 (1959); Camp v. Jiffy Lube No. 114, 309

N.J. Super. 305, 309-11 (App. Div. 1998). Here, establishing such causation is

a complicated, "esoteric" task, which requires the admissible opinions of a

qualified expert. Wyatt, 217 N.J. Super. at 591.

      We do not question Schwartz's credentials as a highly qualified mold

specialist. But his expertise is inadequate to provide a jury with an appropriate

evidential foundation to conclude that the leaks in this case originated from

common areas in the building. He did not rely on the building's engineering

records or plans, even though they were made available to him. He and his

company made no expert observations of water presently leaking through the

windows or migrating from common elements during the time frame of

plaintiffs' problems. The only testing done by Schwartz's firm, as indicated by

                                                                         A-2742-18T1
                                       27
in the report, was to detect the presence of mold in the air and surfaces, not to

trace water flow through the building.

      Similar deficiencies are patent in Strode's analysis. Although Strode has

extensive credentials as an experienced industrial hygienist with a master's

degree in microbiology, he too is not an engineer. 4 He did not perform forensic

testing that could establish, with a proper methodology, that the water in

plaintiffs' unit originated from common elements.          In fact, Strode never

inspected the site. He confined his expert report to a review of documents and

transcripts. Cf. Townsend, 221 N.J. at 57 (in excluding a causation expert under

the net opinion doctrine, the Court noted the expert "took no measurements" and

"did not apply his engineering expertise to present empirical evidence" that

supported the plaintiffs' liability theory).

      Strode's conclusion, like that of Schwartz, that the leaks in plaintiffs' unit

were the result of historical water infiltration within the building are

inadmissible net opinion.

explain their methodology, and demonstrate that both the factual bases and the

methodology are reliable." Id. at 55 (quoting Landrigan v. Celotex Corp., 127

N.J. 404, 417 (1992)). An expert's conclusion should be excluded "if it is 'based

merely on unfounded speculation and unquantified possibilities.'" Ibid. (quoting

Grzanka v. Pfeifer, 301 N.J. Super. 563, 580 (App. Div. 1997)). "[A] trial court

must ensure that an expert is not permitted to express speculative opinions or

personal views that are unfounded in the record." Ibid. (emphasis added); see

      In the present case, we agree that plaintiffs have not presented competent

expert opinion, based upon a sound methodology, to support their theory of

causation against the association and RCP. 5 Consequently, we affirm summary

judgment in favor of those defendants.

      All other points raised on appeal lack sufficient merit to warrant

discussion. R. 2:11-3(e)(1)(E).

      Affirmed.

  We are mindful the record contains documents showing the building has had
numerous problems of water leaks during its three-decade history, and that the
association's board minutes reflect concerns about leaks in past years.
Nonetheless, such lay and anecdotal proof is not sufficient to support plaintiffs'
claim that the damage to their own unit was proximately caused by water leaking
from common areas. Proper expert support was vital.
