M & M Welding & Fabricators Inc.

M & M Welding & Fabricators Inc., a minority-owned and woman-owned small business based in Mt. Airy, Maryland, provides mechanical, welding, and fabrication services to federal agencies as a prime contractor (87% of recent awards) competing predominantly in full-and-open procurements without small-business set-asides. The firm specializes in HVAC infrastructure, steam distribution systems, boiler repair, and utility plant maintenance across federal facilities in the National Capital Region and at select technical campuses nationwide.

Customer concentration is extreme and narrowly geographic. The General Services Administration Public Buildings Service National Capital Region dominates the footprint, accounting for 69 awards with $400.7 million combined potential value—covering 98% of the vendor's total potential-value base. Within that single customer line, M & M Welding holds a $10.5 million indefinite delivery contract (awarded January 2020) for steam plant and distribution system repairs and maintenance at federal facilities in the National Capital Region, from which the vendor has issued recurring $500 thousand delivery orders for steam distribution tunnel repairs, HOTD (Heating Operation and Transmission Division) steam plant repairs, and related infrastructure work. The Department of the Army (34 awards), the Department of the Navy (27 awards), and the National Institute of Standards and Technology (10 awards, $1.2 million combined potential value) round out the top tier, but represent a small fraction of dollars. M & M Welding also works for the Social Security Administration ($8.3 million across 3 awards), the Smithsonian Institution ($85 thousand), and the Department of Veterans Affairs in smaller roles. This concentration creates significant recompete exposure: only three awards (combined potential value $1.2 million) reach ultimate completion within the next twenty-four months, meaning the vendor's pipeline is backloaded with work extending years beyond that window.

Recent activity shows growth in absolute award count—4 awards in 2022 to 22 in 2025—but the trajectory masks underlying volatility. Service Contract Inventory data covering federal services contracts above the $150,000 reporting threshold show SCI-reportable invoiced revenue of $12.2 million across FY2022–FY2025, with FY2024 peaking at $4.4 million across 5.9 FTEs (contract-level reporting). On federal services contracts captured in SCI, median government-paid rates ran around $311/hour, with senior labor pricing through $470/hour. The SCI dataset shows M & M Welding delivered roughly 7 to 34 FTEs per fiscal year on reportable prime contracts, with significant volatility reflecting the lumpiness of project-based facilities work. Across SCI-reportable prime contracts, the vendor uses no subcontractor hours—all delivery is in-house labor.

M & M Welding operates predominantly as a prime contractor but also holds subcontractor relationships with M.C. Dean Inc., Trademasters Service Inc., Johnson Controls Building Automation Systems LLC, and Asrc Federal Facilities Logistics LLC on facilities engineering, operations, and maintenance work at federal buildings, the Pentagon, NASA Goddard Space Flight Center, and other installations. Sub-award examples include water pump replacement, valve repairs, boiler and steam coil replacement, and HVAC system modifications. Recent sub-work dates from July 2026 (water pump replacement under M.C. Dean), June 2026 (tower valve replacements under Trademasters Service), and ongoing work orders across multiple primes supporting federal building mechanical systems in Washington, D.C. and Greenbelt, Maryland.

The vendor's top parent vehicle is the GSA Multiple Award Schedule, against which 56 task orders have been issued. M & M Welding also places work under several Navy and Army indefinite delivery contracts: IDC 47PM0820D0003 (16 task orders, $7.6 million combined potential value), IDC GS11P14YMD0061 (11 task orders, $6.2 million), and smaller Army and Navy IDCs. Work performed spans the National Capital Region (Washington, D.C., Fort Lesley J. McNair) as the primary operational footprint, with secondary work at NIST Gaithersburg campus, NASA Goddard Space Flight Center in Greenbelt, Maryland, Joint Base Andrews, Wallops Flight Facility, and other federal facilities. Concrete recent awards include a $853.6 thousand GSA National Capital Region purchase order for heating and cooling repairs at 600 F Street NW, Washington, D.C. (completion October 2027); a $500 thousand NIST Gaithersburg boiler repair and welding purchase order (completion August 2031); a $260.9 thousand NIST boiler repair order covering high-pressure steam boiler work, water column piping replacement, and diesel fuel tank cleaning to 5-micron specifications (completion March 2027); and a $192.4 thousand Department of the Navy Naval Sea Systems Command definitive contract for B31 TUBA HVAC installation (awarded February 2024). The vendor's capability portfolio centers on boiler maintenance and repair holding ASME "R" stamp and NBBI "R" certifications, steam distribution system maintenance and repairs, chilled water system upgrades, HVAC installation and maintenance, mechanical infrastructure fabrication, and emergency facilities maintenance across civilian federal facilities in the National Capital Region.
