ANGELO SASSI & SON PLUMBING & HEATING, INC.

Angelo Sassi & Son Plumbing & Heating, Inc. specializes in critical mechanical systems maintenance and retrofitting for naval and defense infrastructure, with deep expertise in HVAC installation, plumbing system repairs, and fire alarm integration within maritime environments. Their work on living barges and barge modernization projects demonstrates proficiency in confined-space HVAC system upgrades, sump and tank rehabilitation, drinking water system replacements, and corrosion-resistant piping installations under stringent military operational standards. The contractor brings hands-on experience with split-system HVAC retrofits, flooding system modernizations, and preservation techniques tailored to high-humidity, saltwater-exposed naval assets, ensuring reliability in mission-critical environments. The company maintains a consistent relationship with the Department of Defense, particularly through the Portsmouth Naval Shipyard, delivering maintenance and repair services for naval support vessels and crew accommodations. Their work is focused on sustaining operational readiness through preventive and corrective mechanical system interventions, often under tight timelines and strict compliance protocols for naval engineering specifications. Their primary industry focus is on NAICS 336611 (Ship Building and Repairing), where they provide specialized mechanical system integration and overhaul services for naval vessels and auxiliary floating infrastructure. While they also hold a contract under NAICS 238220 for general plumbing and HVAC services, their market positioning is distinctly anchored in defense maritime applications rather than commercial or civilian construction. As a small, locally based firm in Farmington, New Hampshire, Angelo Sassi & Son operates as a sole proprietorship with no federal certifications on record. Their government market presence is narrowly focused on naval maintenance contracts, leveraging regional proximity to Portsmouth Naval Shipyard and a reputation for precision, durability, and adherence to military-grade technical standards in mechanical system execution.
