Portland Mechanical Contractors

What Portland Mechanical Contractors does

Portland Mechanical Contractors (PMC) is a Pacific Northwest mechanical, electrical, and plumbing (MEP) contractor operating as a wholly-owned subsidiary of JH Kelly LLC since its 2018 acquisition. PMC contributes mechanical service and sheet metal capabilities to the Portland metro market, supporting the combined entity's role as a self-performing, multi-trade contractor serving industrial, commercial, and service-and-maintenance customers across the I-5 corridor from Everett, WA to Salem, OR. Core offerings span HVAC and plumbing design-build, industrial process piping and millwright services, electrical construction and instrumentation, UL 508A panel fabrication, and a 24/7 emergency service and preventative maintenance business covering HVAC, plumbing, electrical, refrigeration, and commercial kitchen equipment.

The combined business operates through five core service lines — Industrial Construction, HVAC & Plumbing, Electrical, 24/7 Service & Maintenance, and Off-Site Manufacturing — supported by an integrated fabrication footprint that includes 65,000+ SF of prefabrication space in Vancouver, WA, a proprietary Stratus Fab Management system, and 3D CAD/BIM-enabled virtual design and construction. Contract structures range from lump sum and GMP (Guaranteed Maximum Price) to T&M (Time & Materials) and design-build arrangements, with multi-year industrial capital projects alongside recurring preventative maintenance agreements.

Revenue is generated through three primary streams: large-scale industrial capital projects (refineries, power plants, semiconductor fabs, food processing plants, pulp and paper mills), commercial construction for healthcare, higher education, hospitality, multi-family housing, and data centers, and a recurring service business with 24/7 emergency response. Distribution is direct to enterprise customers and through general contractor partnerships with Hoffman Construction, Andersen Construction, Skanska, Turner, and JE Dunn. The company employs 1,500+ staff, operates under 4th-generation family ownership (President Mason Evans), and reports one million hours without a lost-time injury (MCAA Category 5 Safety Award).
