Guarantee Interiors, Inc.

Guarantee Interiors, Inc., a service-disabled veteran-owned small business headquartered in St. Louis, Missouri, operates as a prime contractor delivering construction, renovation, and facilities management services exclusively to the Department of Veterans Affairs, competing predominantly under SDVOSB set-asides. The company holds a 100% prime footprint across 434 federal awards with a combined potential value of $844.5 million, performing all work in-house with zero subcontractor engagement.

Guarantee Interiors specializes in healthcare facility infrastructure work grounded in concrete VA medical center projects: pharmacy air handler installation ($4.074 million, Harry S. Truman Veterans Memorial Hospital, Columbia, Missouri, October 2026); roof replacement on three buildings ($4.46 million, Jefferson Barracks, September 2026); Electronic Health Record Modernization infrastructure upgrades ($38.179 million, St. Louis VA Medical Center, May 2023); urgent care clinic construction ($13.432 million, Jefferson Barracks, July 2024); and HVAC system corrections and medical equipment storage improvements ($8.693 million, Columbia VAMC, September 2025). Recent work encompasses site preparation for medical imaging equipment, mechanical system upgrades, hazardous material abatement, emergency repairs, and specialty clinical space renovations across VISN 15's Midwest footprint.

Customer concentration is extreme: the Department of Veterans Affairs Veterans Health Administration Veterans Integrated Service Network 15 (VISN 15) accounts for 407 of 434 awards (96% of activity) and $765.5 million of combined potential value (91% of the portfolio). The Department of Veterans Affairs Technology Acquisition Center Austin represents the secondary customer with 5 awards ($49.7 million). The remaining customer agencies—DoD's ENDIST Kansas City (one $19 million data center construction award, July 2026), VA Headquarters, and VA's Office of Construction and Facilities Management—account for negligible volume.

Guarantee Interiors holds four primary single-award indefinite delivery contracts through VISN 15, each valued at $20 million and designated 100% SDVOSB set-aside: the Columbia VAMC Job Order Contract (awarded January 13, 2025, through January 12, 2027), the Jefferson Barracks JOC (awarded February 3, 2025, through February 2, 2030), the Poplar Bluff VAMC JOC (awarded February 18, 2025, through February 17, 2030), and the John Cochran JOC (awarded February 20, 2025, through February 20, 2027). These vehicles enable task orders ranging from $2,000 to $500,000 for minor construction, repair, and alteration services. Collectively across these four IDIQs, the vendor has placed 131 task orders totaling approximately $66 million in combined potential value to date. The top-ranking parent vehicle by combined value is IDC VA25512D0009 with 35 task orders and $45.3 million potential value.

Activity has grown unevenly year over year: 26 awards in 2022, 22 in 2023, 20 in 2024, a marked jump to 49 in 2025, and 32 awards through October 2026. The vendor faces recompete exposure on 34 awards (combined potential value $88.3 million) with ultimate completion dates in the next twenty-four months, including major EHRM-related contracts, isolation ward construction at Poplar Bluff, and facility renovations across multiple VA medical centers.

NAICS specialization is heavily concentrated in 236220 (Commercial and Institutional Building Construction), representing 412 of 434 awards. PSC coding is similarly narrow: 310 awards under Z2DA (Repair or Alteration of Hospitals and Infirmaries), 48 under D306 (Maintenance of Hospitals and Infirmaries), and 8 under C104 (Construction of Hospitals and Infirmaries).

Service Contract Inventory reporting shows federal service-contract invoicing of $87.3 million across FY2023–FY2025, reflecting $29.1 million in FY2023 (23.9 FTEs), $37.5 million in FY2024 (28.8 FTEs), and $20.8 million in FY2025 (21.9 FTEs). The SCI dataset captures a partial view of the vendor's federal footprint; the full contract portfolio including definitively-priced awards exceeds this invoiced amount significantly. Government-paid hourly rates on federal service contracts ran at a median of $384.60/hr, with rates ranging from $0/hr at the 10th percentile to $1,051.06/hr at the 90th percentile, reflecting the mix of general labor, project management, and specialized technical positions. Guarantee Interiors self-performed all reported SCI hours with zero subcontractor engagement.

The vendor operates under a firm fixed-price contracting model with mandatory RS Means cost estimating compliance and 120-minute emergency mobilization capability requirements on all VA job order contracts. Guarantee Interiors self-performs all labor and maintains no standing subcontractor relationships in its federal portfolio, positioning itself as a vertically integrated facilities services provider rather than a program integrator or teaming prime.
