About the company
Prospect Waterproofing Co, a for-profit construction services company headquartered in Sterling, Virginia, delivers roofing, waterproofing, and specialty trade construction work to federal civilian and defense agencies as both a prime contractor (63% of recent awards) and subcontractor. The company operates in full-and-open competition with no SBA set-aside designations across its federal footprint.
Prospect's federal work centers on building envelope repair and specialty construction. The vendor holds a $444 thousand definitive contract as prime with the Department of Veterans Affairs, awarded September 29, 2026, for roof repair at the Army Technical and Medical Material Center (ATAMMC) at Fort Belvoir, Virginia, with completion scheduled for February 24, 2027. As a subcontractor, Prospect has performed roofing and waterproofing services under Grunley Construction Co., Inc. on Building 618 vehicle maintenance roofing at the Mt. Weather Emergency Operations Center (awarded November 18, 2022) and on roofing and metal panel scope under HSU Development, Inc. for roof assembly renewal at the Lion/Tiger facility (awarded June 29, 2022). A third subcontract under Grunley for RF shielding installation work included roofing scope.
Customer concentration is low and diffuse. The Department of Veterans Affairs anchors the potential-value ranking at $444 thousand across one prime award; the Department of Defense Washington Headquarters Service, Smithsonian Institution, Federal Emergency Management Agency, and the Department of the Army Corps of Engineers Engineering District Baltimore round out the five distinct customer agencies served, accounting for 63% of award count but only 98% of combined potential value — a reflection of the VA award's dominance. Prospect's single named parent vehicle is Indefinite Delivery Contract F16CC10413, which carries one task order.
The award portfolio shows sparse recent activity. Only one award was placed in 2026, with prior activity concentrated in 2022 (three awards) and isolated awards in 2006, 2007, and 2009. One award totaling $444 thousand faces completion within the next twenty-four months and presents recompete exposure. The combined potential value across all eight awards totals $461 thousand; however, the combined obligated dollars across all awards stand at $1.6 million, indicating substantial prior performance delivery against these vehicles. Service Contract Inventory data shows Prospect reported 1,443 FTEs to the federal government in FY2022 but scaled back to 6.6 FTEs in FY2024 and 4.5 FTEs in FY2025, all within its subcontractor role; no SCI-reportable prime contracts appear in the dataset. The vendor's federal services footprint via SCI is a small subset of its total enterprise revenue.
