About J & J Mechanical And Construction Group LLC
J & J Mechanical And Construction Group LLC, a service-disabled veteran-owned small business headquartered in Jersey City, New Jersey, operates as a prime contractor (100% of recent awards) delivering mechanical, HVAC, plumbing, and facility renovation services to federal agencies, predominantly under SDVOSB set-asides. The company is a limited liability partnership structured as a self-certified small disadvantaged business and veteran-owned business, with primary NAICS concentrations in plumbing, heating, and air-conditioning contracting (238220, 39 awards) and commercial and institutional building construction (236220, 16 awards).
Customer concentration is extreme: the Department of Veterans Affairs Veterans Health Administration Veterans Integrated Service Network 2 (VISN 2) accounts for 65 of 71 total awards (92%) and $66.3 million of the $138.3 million combined potential value. However, recent activity signals diversification into the Department of the Air Force. The Air Force Defense Finance and Accounting Service awarded a single $71.5 million multiple-award indefinite delivery contract for mechanical infrastructure support at Joint Base McGuire-Dix-Lakehurst through August 2031, which now anchors the vendor's second-largest customer by potential dollars. Air Mobility Command placed two task orders against that IDIQ (combined $246 thousand) for boiler and control replacement at McGuire AFB. The Air National Guard placed one award ($212 thousand) for HVAC unit replacement at Newburgh. VISN 2, despite concentration, remains the steady volume customer with 65 awards spanning emergency repairs, facility upgrades, and major renovation projects.
SDVOSB set-aside posture defines the prime footprint. Approximately 70% of recent VISN 2 awards carry explicit SDVOSB set-aside designations (sole-source and competitive). Work ranges from micro-purchases under $40 thousand (relief valve replacement, CT scan AC unit replacement, emergency repairs) through major definitive contracts. Representative prime work includes a $19.216 million definitive contract (March 2026) for replacement of main EMD cooling towers and generators at James J. Peters VA Medical Center in Bronx; a $14.743 million definitive contract (April 2026) for renovation of the 6B Outpatient Mental Health wing at the same facility, encompassing asbestos abatement, demolition, carpentry, plumbing, HVAC, electrical, and security systems; a $10.9 million definitive contract (September 2025) for brick facade cleaning and repairs at Margaret Cochran Corbin VA Campus in Manhattan; and a $5.453 million definitive contract (September 2024) for emergency temporary boilers at Northport VA Medical Center. Recent smaller emergency and repair work includes a $758 thousand purchase order for rental and installation of temporary HVAC equipment (200-ton chiller, air handling units) at Brooklyn VA Medical Center and a $3.43 million definitive contract for replacement of fan coil units in Building 18 at Castle Point VA Medical Center.
Activity has grown year over year — three awards in 2022 to thirteen in 2024 — with an acceleration to eleven awards in 2026 (as of April 30, 2026). The recompete cliff window shows six awards (combined potential value $32.3 million) completing in the next twenty-four months, creating recompete exposure across multiple VISN 2 and Air Force projects. Obligated dollars stand at $65.4 million (47% of combined potential value), indicating active performance.
Service Contract Inventory data is sparse and does not capture J & J Mechanical's true service-contract activity; the vendor appears in SCI with minimal reportable invoiced revenue but recorded workforce presence (1.4 FTEs in FY2022, 1.1 FTEs in FY2024 across both prime and sub roles), suggesting most federal work falls below the $150 thousand SCI reporting threshold or is classified as goods-and-materials work rather than billable services. The vendor does not operate as a subcontractor in the award portfolio — all 71 awards are primes — and shows no engagement of named subcontractors across SCI prime records, indicating the company builds and manages its own delivery teams for facility infrastructure work.
The vendor holds a position on the Joint Base McGuire-Dix-Lakehurst HVACR Equipment Services 2025–2031 IDIQ (an Air Force Total Small Business award), which carries a $71.5 million ceiling through August 2031 and structures ongoing mechanical equipment maintenance, inspection, testing, construction, and repair across the base. This represents a strategic foothold in Air Force facility operations separate from the VISN 2 concentration and positions J & J Mechanical for responsive, task-order-based work without separate solicitations.
