Colonialwebb Contractors Company

Colonialwebb Contractors Company, doing business as Colonialwebb Contractors Corp, is a subsidiary of Comfort Systems USA Inc. that delivers HVAC, building automation, and facility maintenance services to the federal government as a prime contractor, competing without set-aside designations in the full-and-open marketplace. The vendor operates from Richmond, Virginia, as a for-profit corporate entity within the broader Comfort Systems USA enterprise, which positions mechanical, electrical, and plumbing infrastructure delivery across defense and civilian agencies.

Colonialwebb's capability portfolio centers on preventative and emergency HVAC repair, building automation system maintenance, air-handling equipment installation, chiller replacement, boiler installation, and compressed air and electrical infrastructure work. Representative recent work includes a $7,585 purchase order from the U.S. Coast Guard (June 2026) to replace a Trane chiller electronic expansion valve at USCG Base Portsmouth with firm-fixed-price performance through July 2026; a $16,872 sole-source purchase order from Naval Sea Systems Command (April 2024) for three-year preventative maintenance on a building automation system at Dahlgren, Virginia, under NAICS 238220 and PSC J041; and a $46,618 boiler installation contract with the Federal Correctional Institution Ashland (January 2023). Work across the portfolio spans facility mechanical systems, with Service Contract Labor Standards (prevailing wage) applying to most field positions.

Customer concentration is dispersed across twenty-four federal agencies, with the top five accounting for 49% of recent awards by count but a different ranking by potential value. The Defense Logistics Agency Distribution leads on both dimensions (11 awards, $3.3 million combined potential value), while the General Services Administration Public Buildings Service Region 3 anchors a single $1.5 million award that carries outsized dollar weight. The Department of Veterans Affairs National Cemetery Administration and Veterans Integrated Service Network 6 account for fifteen combined awards on smaller unit values ($132 thousand and $53 thousand respectively), and the U.S. Special Operations Command placed six awards valued at $548 thousand combined. The top five customer ranking by potential value accounts for 89% of combined potential dollars across the portfolio.

Colonialwebb places task orders against three parent indefinite delivery contracts: H9224018D0003 (5 task orders, $48 thousand combined value), VA78613D0040 (4 task orders, $50 thousand combined value), and VA78613D0036 (1 task order, $6 thousand combined value). Activity has declined over the past five years—three awards in 2021 dropping to one in 2026—with minimal recompete exposure; only one award reaches ultimate completion inside the next twenty-four months. Colonialwebb operates exclusively as a prime contractor (100% of recent awards) with no identified subcontractor relationships in the federal record. The SCI dataset captures minimal service-contract invoicing—two records spanning FY2022 through FY2024, both in a named-subcontractor capacity, suggesting Colonialwebb's federal work falls predominantly below the $150,000 SCI reporting threshold or is classified as goods and repairs rather than reportable service contracts. NAICS concentration is heavy in plumbing, heating, and air-conditioning contracting (36 awards), with subordinate work in machinery repair and maintenance and steam/air-conditioning supply, mirroring the PSC distribution across refrigeration, HVAC, and plumbing equipment repair.
