The second member bridges across and conceals the joint between the article and the supporting structure associated therewith.

BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to a method and molding system for use in the replacement of doors and windows and, more specifically, to: removing existing doors and windows from structures having an exterior stucco surface; installing replacement doors and windows, respectively; and a molding system for use in the same. 
     2. Description of the Prior Art 
     A change in conventional methods and devices accompanying these methods for removing existing articles, such as windows and doors, from supporting structures having a stucco surface and installing replacement articles in the same is felt to be long overdue. Most conventional methods known for removing existing articles from associated opening in structures first encompass the removal of the stucco surface about the perimeter of the article. Known methods enlist an individual to strip the stucco surface by profusely striking the same with a pick hammer, thus chipping away at the stucco surface in chunks of various size and proportions. The resultant effect, as shown in FIG. 1, frequently requires extensive patching or stucco repair about the perimeter of the opening in which the article was removed. A method which would limit the quantity of stucco being removed would reduce the amount of repair required. Further, a device incorporated into such an improved method which would conceal the area from which the stucco was removed could eliminate patching and repair altogether. 
     U.S. Pat. No. 1,048,988 issued Dec. 31, 1912 to Robert D. Mayo, Sr. discloses a sheet metal casing for doors, windows and the like. The casing is vertically and horizontally adjustable within an opening in the wall. The casing includes an inner casing, an outer casing, and a stop. The outer casing is slidably engagable with the inner casing. 
     U.S. Pat. No. 1,150,790 issued Aug. 17, 1915 to Charles J. Swanson describes a sheet metal door trim and a means for attaching the same to the walls and more specifically, to the jambs and lintel about the opening of a door or window. Holding clips are fastened about the opening and the trim is sprung into place upon the clips. 
     U.S. Pat. No. 1,929,634 issued Oct. 10, 1933 to Charles P. Gifford teaches of a frame construction for building openings, such as window openings or the like. The trim includes an inwardly extending flange which seats against the blocking of the window and is secured to this blocking by a wood facing and a suitable attaching means. Once the window is set, plastering is done and the trim is embedded in the plaster. 
     U.S. Pat. No. 2,562,105 issued Jul. 24, 1951 to Wilbur L. Lang shows a door casing made from extruded plastics and other materials. The casing includes inner and outer elongated corrugated members each having two integral longitudinal sections disposed at right angles to each other. One of the two longitudinal sections is tapered for insertion between the plaster and the stud. Inner and outer casing members are joined together by an integral stop. 
     U.S. Pat. No. 2,582,765 issued Jan. 15, 1952 to Lewis J. Brew discloses trim used in buildings, such as door and window casings and more particularly, to metal trim for doors and windows. The casing includes reinforcing members engagable with two side pieces and a door stop for adjoining the two side pieces. 
     U.S. Pat. No. 5,018,325 issued May 28, 1991 to Oliver Geen et al. describes a system and method of shielding the periphery of a framework of a building opening adjacent a building surface. The system consists of a first elongated member associated with the article occupying the opening and a second elongated member associated with the building surface. Each elongated member has an elongated channel. An angular facia member communicates with both the first and second elongated members. The angular facia member is slidably insertable into each of the channels. 
     Swedish Patent No. 180,024 issued May 3, 1962 to M. R. Jonssos discloses a device for concealing a joint between a wall and a frame. The device is comprised of a sheet having a U-shaped cross-section. One branch of the U-shaped member passes into a groove in the frame and includes a hook which is bent in a direction toward the frame to frictionally engage with the frame. The other branch of the U-shaped member, under resilience, braces against the wall. 
     None of the above inventions and patents, taken either singly or in combination, is seen to describe the instant invention as claimed.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
     The present invention relates to a method and a molding system generally for replacing articles in structures having an outermost surface, and, more specifically, for replacing doors and windows in stucco buildings. Referring to FIGS. 2 through 4, using a conventional measuring device (not shown), measure the exterior cross-section of the existing article or existing window 20, thus establishing a height H1 and a width W1. Next, measure the cross-section of the replacement article or window 30 to establish a height H2 and a width W2. With these measurements completed, a determination can be made as to the margin M1, M2 of stucco to be removed about the existing periphery P1 of the existing window 20. This is accomplished by determining the difference Δ H between the heights H2 and H1 as well as the difference Δ W between the widths W2 and W1 and dividing these differences Δ H, Δ W by a factor of two, thus producing values which correspond to the margin M1 of stucco 1/2Δ H to be removed along both the top and bottom edges of the existing window 20 as well as the margin M2 of stucco 1/2Δ W to be removed along both the left and right sides of the existing window 20. Mark the stucco surface S about the periphery P1 of the existing window 20. This may be performed in a conventional manner, such as inscribing tick marks T and popping a chalk line L along the tick marks T. Hence, a new periphery P2 has been established, one which will accept the replacement window 30 being installed. 
     The determination of a new perimeter about an opening may vary depending on the configuration of the opening. For example, whether the opening may be arcuate, circular, elliptical, et cetera. The opening illustrated was chosen for simplification of this description. 
     Now, referring to FIGS. 4 through 7, after the new periphery P2 has been marked, cut through the stucco surface S along the chalk line L. This step may be performed with the aid of worm drive saw having a diamond or abrasive blade (not shown). The structure or building B associated with the existing window 20 should be sealed so as to prevent any dust created through the cutting of this stucco surface S from entering interiorly of the building B. The depth of the cut C should be slightly less that of the thickness of the stucco surface S. Preferably, the integrity of the underlayment 14, that is, the underlying asphalt impregnated felt paper, should not be compromised. Typically, standard stucco thickness ranges between seven eighths of an inch to one inch. Cutting the stucco at a depth D of three quarters of an inch could reduce and possibly eliminate the disfigurement of the felt paper 14. Flashing paper and caulking (not shown) can be used, if necessary, to repair areas of damage to the underlayment 14. 
     The margin M1, M2 of stucco surface S defined within the new periphery P2 is now removed. This task could be completed through the use of a small cold chisel (not shown), holding the chisel centrally in the margin M1,M2 against the stucco surface S. The chisel should be held at an angle 45 degrees relative to the stucco surface S. In most circumstances, this margin M1, M2 of stucco surface S cleanly separates form the underlying wire or mesh lathing 16. Occasionally, it may be necessary to cut the lathing 16 which secures the stucco surface S along the periphery of the cut C, and thus, prevent any unnecessary damage to the stucco surface S outside of the margin M1,M2 and beyond the area which the molding system 100 will cover. Wire nippers (not shown) may facilitate in cutting the lathing 16. If during this removal step the stucco surface S becomes damaged beyond the area in which the molding system 100 (shown in FIGS. 10 through 12) will cover, the damaged area may easily be repaired with proper color coating or through patching damaged area and painting the patched damaged area with matching masonry paint. 
     After the necessary margin M1,M2 of stucco surface S has been removed, the remaining lathing 16 is cut with the wire nippers as closely to the cut C or the new periphery P2 as possible. All of the lathing nails 18 are removed from the margin M1,M2 as well. This renders a clean cut condition within the margin M1,M2 which maximizes the removal of the existing window 20 as well as the quality of impending installation of the replacement window 30 in regards to vapor barrier, durability, and aesthetic appearance. 
     Once the aforementioned steps have been completed, a thorough clean up of the exterior of the building B is conducted. This reduces the risk of any dust or debris (created in the foregoing steps) from entering into the building B, thus lessening the amount of interior clean up. 
     Next, remove the fasteners 22 from the mounting flange 24 or nail on fin which secures the existing window 20 to the surrounding framing members 26. It may be necessary to lift the flashing paper 14 about the sides and top of the existing window 20 in order to gain access to fasteners 22 therebehind. Just prior to removing the last fastener from the mounting flange 24, apply a slight inward force F IN  against the existing window 20 to ensure that the same does not fall forward out of the opening 10, as is shown in FIG. 7. When the last fastener 22 is removed and with the existing window 20 being supported from the exterior of the building B, the top of the existing window 20 may freely fall forward out of the opening 10, pivoting on the bottom thereof. The bottom may now be lifted and completely removed from the opening 10. If necessary, a gentle outward force F OUT  may need to be exerted against a top interior portion of the existing window 20 to urge the same outward. This type of pivotal or "hinge-type" removal may reduce the risk of injury. 
     Once the existing window 20 has been removed, the replacement window 30 may be installed. Measure the cross-section of the opening 10. Compare these measurements with those required by the manufacturer's specifications for the installation of the replacement window 30 (shown in FIGS. 8 through 10). If the opening 20 is too large, shim the opening 10 equally about the periphery P1 until the opening 10 is sized according to the specifications. It is crucial that the opening 10 be shimmed equally about the periphery P1 so as to ensure that the replacement window 30 is centered within the opening 10 when the shimming is completed. It is advisable that the opening 10 be measured once again and that this measurement be compared with the manufacturers specification. Also, measure the replacement window 30 and compare this measurement with the measurement of the opening 10. This will further ensure that the opening 10 has been properly sized. 
     Referring to FIGS. 8 through 10, after the opening 10 has been sized, the replacement window 30 can be installed in the opening 10. Caulk the innermost edge of the new mounting flange 34 and set the replacement window 30 in the opening 10. Both the sides and the top of the existing flashing paper 14 should overlap the new mounting flange 34 and the new mounting flange 34 should overlap the existing bottom strip of flashing paper 14 along the bottom of the replacement window 30 (shown in FIG. 9). This overlapping is a conventional practice which prevents penetration of moisture beyond the new mounting flange 34. The caulking of the innermost edge of the mounting flange 34 further prevents penetration of moisture beyond the new mounting flange 34. 
     The replacement window 30 is now checked to ensure that the same is square as well as level and plumb in the opening 10. More shimming about the opening 10, such as with shim 28, may be necessary to properly center the replacement window 30 therein. This guarantees the long lasting functional and aesthetic qualities of the replacement window 30. At this point, the replacement window 30 is secured in place, preferably with corrosion resistant (i.e. galvanized) fasteners 32 to the underlying or surrounding framing members 26. 
     Determine the dimensions and the desired mounting locations of the angular stress retention clips 102. Cut the angular stress retention clips 102 according to the dimensions and apply a generous and uninterrupted bead of adhesive caulk 106 along the entire length of each angular stress retention clip 102. The caulk 106 is applied on the surface of the angular stress retention clip 102 which abuts the cut C or the new periphery P2 the stucco surface S. The angular stress retention clips 102 are each then pressed into position within the recess R about the perimeter of the replacement window 30. The innermost edge 108 of each angular stress retention clip 102 overlaps the previously secured new mounting flange 34 of the replacement window 30. An angular stress retention clip 102 is secured along each the top, the bottom, and the two sides of the replacement window 30. Corrosion resistant fasteners 22 are used to secure the angular stress retention clips 102 in place, the angular stress retention clips 102 being secured to the existing underlying framing members 26 surrounding the replacement window 30. 
     Next, determine the necessary dimensions for the peripheral molding 120. Measure from the exterior molding receptor groove 36 located along one edge of the replacement window 30 to the exterior molding receptor groove 36 on an opposite edge of the replacement window 30. This will provide the interior lengths I1, I2 of the peripheral molding 120 (shown in FIG. 9). Cutting opposite ends of each piece of peripheral molding 120 at an angle of 45 degrees will ensure a continuous engagement of the peripheral molding 120 about the perimeter of the replacement window 30 and a solid engagement of the peripheral molding 120 with both the angular stress retention clips 102 and the receptor groove 36. 
     Finally, after having measured and cut the pieces of peripheral molding 120, apply the peripheral molding 120 by first engaging a return 122 located at one end of the peripheral molding 120 with a tab 110 located on the underside of the angular stress retention clips 102 juxtaposed the surface S of the supporting structure. Next, engage a return 124 located at an opposite end of the peripheral molding 120 with the receptor groove 36 located about the perimeter of the replacement window 30. It may be necessary to gently tap the peripheral moulding 120 into the tab 110 and the receptor groove 36, such as with a rubber mallet (not shown). 
     FIGS. 11 and 12 show the molding system 100 being comprised of two parts, an angular stress retention clips 102 and a peripheral molding 120. The peripheral molding 120 is comprised of an elongated substantially U-shaped member having a first substantially planar surface 126. The first surface 126 has a second surface 128 attached at one end and a third surface 130 at an opposite end. Each of these surfaces 128,130 are attached at substantially right angles relative to the first surface 126. The second surface has a bend 132 lying in a plane parallel to that of the first surface 126 and being directed toward the third surface 130. The bend 132 has a protrusion 134 directed toward the first surface 126. The bend 132 and protrusion 134 in combination with the second surface 128 form a first return 122 which is frictionally engagable with the angular stress retention clip 102. The third surface 130 has a protrusion 134 in a direction away from the second surface 128. The protrusion 134 in combination with the third surface 130 form a second return 124 which is frictionally engagable with a receptor groove 34 located around the perimeter of the replacement window 30. When the peripheral molding 120 is installed about a window, the joint between the window and the supporting surface is concealed. 
     The angular stress retention clips 102 is an elongated substantially Z-shaped member having a first substantially planar surface 112 integral with a second substantially planar surface 114, these surfaces 112, 114 being disposed at an angle A of 90 degrees relative to one another. These two surfaces 112,114 are fastened in a recess R about the perimeter of the replacement window 30 such that the first surface 112 contacts the flashing 14 and overlaps the new flange 34 and the second surface 114 contacts the cut edge C of the surface S of the supporting structure B. A third substantially planar surface 116 is integral with the second surface. These two surfaces 114,116 are disposed at an angle B less than 90 degrees relative two one another and opposite to angle A. This configuration creates a tension force F T  between the third surface 116 and the surface S of the supporting structure B attached thereto. A tab 110 is provided at an end of the third surface 116 opposite the end integral with the second surface 114. The first return 122 of the peripheral molding 120 is frictionally engagable with the tab 110. The tension force F T  holds the first return 122 tight between the third surface 116 of the angular stress retention clip 102 and the surface S of the supporting structure B. 
     It is to be understood that the present invention is not limited to the sole embodiment described above, but encompasses any and all embodiments within the scope of the following claims.
