Brief summary: This phase I trial studies the side effects and how well tremelimumab and durvalumab work in treating patients with colorectal cancer that has spread to the liver and can be removed by surgery. Immunotherapy with monoclonal antibodies, such as tremelimumab and durvalumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread.

Detailed description: PRIMARY OBJECTIVES:

I. Assess the safety and feasibility of adding tremelimumab 75 mg intravenously (IV) plus durvalumab (MEDI4736) 1500 mg administered once pre-operatively and 4 cycles of durvalumab 1500 mg IV every 4 weeks for 4 cycles post-operatively in patients who are candidates for resection for colorectal cancer liver metastases.

SECONDARY OBJECTIVES:

I. Explore the changes in various immune parameters, including programmed cell death-1 ligand 1 (PD-L1) and programmed cell death1 (PD-1) expression in the tumor, over treatment and correlate with response and survival with goal of biomarker discovery.

II. Estimate the relapse-free survival (RFS) in all enrolled subjects.

OUTLINE:

Patients receive tremelimumab IV over 1 hour and durvalumab IV over 4 hours during week 11. Between weeks 15 and 17, patients undergo liver surgery. Patients then receive durvalumab IV over 1 hour during weeks 21, 25, 29, and 33.

After completion of study treatment, patients are followed up twice a year for 5 years.

Eligibility criteria: Inclusion Criteria:

* Patients must have histologically or cytologically confirmed colorectal cancer with liver metastases deemed resectable by a general or liver surgeon (resectability may involve the use of ablative techniques to some but not all liver metastases); those patients with known disease outside of the liver are not eligible (except for patients with primary lesions in place that are planned for resection or nonspecific lung metastases \< 1 cm)
* Patients must have measurable disease, defined as at least one lesion that can be accurately measured in at least one dimension (longest diameter to be recorded) as \>= 10 mm with spiral computed tomography (CT) scan
* All lines of prior therapy accepted; subjects with prior hepatic or extra-hepatic resections of metastatic disease will be included
* Life expectancy of greater than 6 months
* Eastern Cooperative Oncology Group (ECOG) performance status =\< 1 (Karnofsky \>= 70%)
* Leukocytes \>= 3,000/mcL
* Absolute neutrophil count \>= 1,500/mcL
* Platelets \>= 100,000/mcL
* Total bilirubin \< 1.5 X institutional normal limits (subjects with known Gilbert syndrome are eligible with total bilirubin \< 3.0 mg/dL)
* Aspartate aminotransferase (AST) (serum glutamic oxaloacetic transaminase \[SGOT\])/alanine aminotransferase (ALT) (serum glutamic-pyruvic transaminase \[SGPT\]) =\< 3 X institutional upper limit of normal
* Creatinine within normal institutional limits OR creatinine clearance \>= 60 mL/min/1.73 m\^2 for patients with creatinine levels above institutional normal
* Known or ordered molecular testing for MSI, BRAF, and KRAS status
* Evidence of post-menopausal status or negative urinary or serum pregnancy test for female pre-menopausal patients; women will be considered post-menopausal if they have been amenorrheic for 12 months without an alternative medical cause; the following age-specific requirements apply:

  * Women \< 50 years of age would be considered post-menopausal if they have been amenorrheic for 12 months or more following cessation of exogenous hormonal treatments and if they have luteinizing hormone and follicle-stimulating hormone levels in the post-menopausal range for the institution or underwent surgical sterilization (bilateral oophorectomy or hysterectomy)
  * Women \>= 50 years of age would be considered post-menopausal if they have been amenorrheic for 12 months or more following cessation of all exogenous hormonal treatments, had radiation-induced menopause with last menses \> 1 year ago, had chemotherapy-induced menopause with last menses \> 1 year ago, or underwent surgical sterilization (bilateral oophorectomy, bilateral salpingectomy or hysterectomy)
* Ability to understand and the willingness to sign a written informed consent document
* Weight \> 30 kg (required for flat dose-based administration of study agents)

Exclusion Criteria:

* Prior chemotherapy \< 2 weeks prior to study drug treatment and treatment related adverse events that have not recovered to baseline or grade 1 (alopecia excluded); prior radiation therapy \< 4 weeks prior to study drug treatment
* Patients may not be receiving any other investigational agents
* Active or prior documented autoimmune or inflammatory disorders (including inflammatory bowel disease \[e.g., colitis or Crohn's disease\], diverticulitis \[with the exception of diverticulosis\], systemic lupus erythematosus, sarcoidosis syndrome, or Wegener syndrome \[granulomatosis with polyangiitis, Graves' disease, rheumatoid arthritis, hypophysitis, uveitis, etc.\]); the following are exceptions to this criterion: a) patients with vitiligo or alopecia; b) patients with hypothyroidism (e.g., following Hashimoto syndrome) stable on hormone replacement; c) any chronic skin condition that does not require systemic therapy; d) patients without active disease in the last 5 years may be included but only after consultation with the study physician; d) patients with celiac disease controlled by diet alone
* Subjects with a condition requiring systemic treatment with either corticosteroids (\> 10 mg daily prednisone equivalents) or other immunosuppressive medications within 14 days of study drug administration; inhaled or topical steroids and adrenal replacement doses \> 10 mg daily prednisone equivalents are permitted in the absence of active autoimmune disease
* Prior exposure to T cell checkpoint inhibitor therapies, including durvalumab and tremelimumab
* Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, interstitial lung disease, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements
* Known allergy or hypersensitivity to any of the study drugs or any of the study drug excipients
* History of active primary immunodeficiency

* Any concurrent chemotherapy, biologic, or hormonal therapy for cancer treatment, concurrent use of hormonal therapy for non-cancer-related conditions (e.g., hormone replacement therapy) is acceptable
