Mcdevitt & Sons Plumbing & Heating, Inc.

Mcdevitt & Sons Plumbing & Heating, Inc., a Department of Transportation-certified Disadvantaged Business Enterprise based in Severn, Maryland, delivers plumbing and mechanical infrastructure repair and maintenance services exclusively to Navy installations as a prime contractor, operating as a for-profit Subchapter S corporation with no subcontract footprint in its federal award history. The vendor competes in full-and-open procurements — eighteen recent awards carried no set-aside designation, though one 2025 award was set aside for total small business, and the vendor qualifies as a small business across its active portfolio.

Mcdevitt & Sons has worked solely with four Navy entities, with customer concentration anchored by Navy Installations Command (7 awards, $510 thousand combined potential value) and Naval Facilities Engineering Command (6 awards, $267 thousand combined potential value), accounting for 100% of recent awards. The vendor's work spans water system repairs, chilled water loop maintenance, potable waterline breaks, sanitary drain investigation, water valve replacement, and emergency chilled water connection installation — all fielded at the Naval Support Activity Bethesda, Maryland installation. Representative recent awards include a $190,488 purchase order from Navy Installations Command in June 2025 for repair of a leaking underground chilled water loop near Building 16; a $184,891 purchase order in March 2025 for replacement of domestic water systems; a $155,752 purchase order from Naval Facilities Engineering Command in March 2026 for water main break repair; and a $218,000 award from Navy Installations Command in April 2026 for replacement of chilled and condenser water pipes, gauges, and valves. All awards are firm fixed-price purchase orders with short performance windows (typically thirty to ninety days).

Mcdevitt & Sons does not sit on GWACs, BPAs, or agency-wide IDIQs; all eighteen awards are discrete point-of-contact task orders issued directly by Navy offices. Activity profile shows seven awards in 2025 against one in 2024 and sporadic prior volume — three awards in 2014, two in 2016 — suggesting renewed engagement with Naval Support Activity Bethesda starting in 2024. Combined potential value across all eighteen awards totals $848 thousand, with $686 thousand obligated (81% of potential value). The vendor's NAICS concentration centers on Water and Sewer Line and Related Structures Construction (10 awards) and Commercial and Institutional Building Construction (6 awards), with primary PSC coding in Construction of Water Supply Facilities (8 awards). The source indicates prior subcontract engagement with DynCorp International on Navy contracts, though no current sub-awards appear in the recent footprint.
