Trusted. Since 1923.
JH Kelly is a fourth-generation family-owned company with roots in Southwest Washington that stretch back to 1923. Originally a relatively small residential and commercial plumbing and heating contractor based in Longview, Washington, JH Kelly has steadily expanded our service footprint and market share over the last century.
Currently, we maintain offices and fabrication shops in Bellingham, Seattle, Longview, and Vancouver in Washington State, and Milwaukie in Oregon. From those locations, we serve clients throughout Washington, Oregon, Idaho and Montana. As a full-service Mechanical (both wet and dry), Electrical, and Plumbing contractor with 24/7 service, we are able to address any mechanical need for local contractors and business owners in the Pacific Northwest.
Our highly skilled craft successfully perform work in semiconductor manufacturing, mission-critical, healthcare, life sciences, food processing, commercial, and mixed-use facilities as well as industrial sectors including petroleum and chemical, pulp & paper, wood products, diversified manufacturing, and many others. In addition to supporting new construction and renovation projects, we also maintain a robust service group capable of quickly responding to any mechanical, electrical, or plumbing issue or implementing comprehensive preventative maintenance plans.
