PORT MADISON CONSTRUCTION CORPORATION

Port Madison Construction Corporation specializes in mission-critical infrastructure maintenance and renovation for defense installations, with deep expertise in commercial and institutional building construction. The contractor delivers comprehensive solutions including HVAC system replacements, boiler and burner upgrades, stormwater management installations, pavement regrading and repaving, concrete repair, handrail restoration, and sanitary sewer video inspections. Their technical proficiency spans mechanical, electrical, and civil systems integration within active military facilities, demonstrating consistent ability to execute complex, safety-sensitive projects under strict operational constraints. Key differentiators include precision in utility system retrofits, compliance with DoD environmental and safety standards, and experience working within constrained, high-security naval bases such as Kitsap and NASWI. The company maintains a strong, sustained relationship with the Department of Defense, primarily supporting U.S. Navy installations across the Pacific Northwest. Their work focuses on sustaining aging infrastructure—replacing obsolete heating systems, repairing critical pavement and dock surfaces, upgrading pumpwells and electrical circuits, and installing oil-water separators—to ensure operational readiness and regulatory compliance. Projects consistently require coordination with base utilities, environmental controls, and facility operations teams, indicating a mature understanding of military installation workflows. Port Madison Construction’s primary focus is NAICS 236220, which encompasses the construction, renovation, and repair of non-residential buildings and site infrastructure. They specialize in facility sustainment rather than new construction, positioning themselves as a trusted partner for lifecycle management of DoD-owned assets. Their work aligns with military installation modernization priorities, particularly in energy efficiency, stormwater compliance, and structural integrity. As an 8H-coded entity based in Poulsbo, Washington, the company operates as a small business with regional focus on the Pacific Northwest defense corridor. While no formal government certifications are listed, their consistent performance on sensitive DoD projects underscores reliability, regulatory awareness, and technical competence in defense-contracted construction environments.
