Angelo Sassi & Son Plumbing & Heating, Inc.

Angelo Sassi & Son Plumbing & Heating, Inc., a small business Subchapter S corporation based in Farmington, New Hampshire, provides plumbing, heating, ventilation, air-conditioning, and facility maintenance services to the Department of the Navy primarily as a prime contractor (96% of recent awards), with specialized expertise in barge, shipyard, and naval installation infrastructure support. The vendor competes predominantly under small business set-asides, with awards split between Total Small Business and non-set-aside designations on a single-award indefinite delivery contract and follow-on task orders.

Angelo Sassi & Son's customer concentration is heavily skewed toward Navy operational and supply commands. The top five funding organizations account for 91% of recent awards by count and 99% by combined potential value, with the Naval Sea Systems Command dominating both metrics: 24 awards valued at $10.4 million combined potential value. The vendor also serves the Naval Supply Systems Command (15 awards, $206 thousand combined potential value), Naval Installations Command (9 awards, $196 thousand combined potential value), Defense Finance and Accounting Service (8 awards, $95 thousand combined potential value), and Naval Facilities Engineering Command (5 awards, $1.9 million combined potential value), with minor work for the Federal Aviation Administration. The Navy's potential-value ranking differs slightly from award count — Naval Facilities Engineering Command's $1.9 million in five awards reflects single larger values versus NAVSEA's distributed task-order pattern.

The vendor's capability portfolio centers on living-barge maintenance and repair, encompassing hull, mechanical, electrical, fire protection, and auxiliary systems work at Portsmouth Naval Shipyard in Kittery, Maine. Representative work includes a $1.887 million indefinite delivery contract (single award, non-set-aside, running through September 2027) that serves as the parent vehicle for multiple task orders, a $602.2 thousand Total Small Business purchase order for YFBN-41 barge modernization including flooding alarm, fire alarm, HVAC, and collection-tank repairs at Naval Submarine Base New London (June 2025), and a $249.9 thousand Total Small Business HVAC maintenance contract for Portsmouth Naval Shipyard dry docks (September 2025). The indefinite delivery contract has obligated approximately $1.02 million across three delivery orders to date, representing roughly 54 percent of the $1.887 million ceiling.

Angelo Sassi & Son holds positions on two Navy IDIQs and a GSA Region 1 Construction IDIQ. The largest vehicle is Indefinite Delivery Contract N4008506A2818, which carries 34 task orders valued at $519 thousand combined potential value (a highly distributed, task-order-intensive vehicle with small individual calls). Indefinite Delivery Contract N3904022D0007 carries 4 task orders valued at $2.9 million combined potential value. Blanket Purchase Agreement N4008513A8030 carries 4 task orders valued at $83 thousand combined potential value. The GSA Region 1 Construction IDIQ accounts for 2 task orders.

Activity has declined year over year from four awards in 2022 to one award in 2026 (a $818.5 thousand purchase order in January 2026), with three awards (combined potential value $3 million) reaching ultimate completion inside the next twenty-four months and therefore subject to recompete. The vendor's footprint is heavily single-customer dependent: NAVSEA represents 79% of combined potential value across the entire award portfolio.

Angelo Sassi & Son operates as a prime on nearly all work; sub engagement is minimal — three subcontractor awards under Cornerstone Construction Services, LLC (plumbing and HVAC work on federal building fit-ups in Burlington, Vermont, in 2024) and 381 Constructors (CIA plumbing work in 2022). Service Contract Inventory data shows minimal activity, with 0.1 FTEs on a single SCI subcontractor record in FY2024, indicating that the vendor's federal service-contract work above the $150,000 reporting threshold is sparse and routed as sub labor rather than prime delivery. The vendor's federal footprint is goods, products, and facility-maintenance purchase orders and task orders below or outside the SCI threshold rather than labor-intensive service contracts.
