What We Do

Since its inception in 1904, Blythe has offered plumbing and piping services to clients throughout the Pacific Northwest. Whether the project is a large industrial facility or small commercial office building,

Blythe has the knowledge and skill to design, build, and install appropriate plumbing, piping and HVAC systems for the customer’s application.

In addition, careful scrutiny of existing systems allows for efficient and cost effective upgrades; and service and repair of any piping or HVAC system is handled by Blythe’s service department. In the 1980’s Blythe diversified and became a full service mechanical contractor, adding HVAC, sheet metal, and commercial refrigeration to its work scope in order to better serve its customers. With our staff of professional engineers, experienced project managers, and talented and dedicated installation crews, Blythe has expertise in all aspects of the mechanical construction industry.

Blythe has earned the respect and loyalty of our customers for our ability to select and install the appropriate systems for their needs.

Blythe performs new construction, remodel, repair and service for an extremely wide range of mechanical systems. Mechanical work installed and serviced includes a wide range of plumbing and piping systems, mechanical rooms, HVAC/sheet metal and airside mechanical, commercial, and industrial refrigeration including ammonia systems.

Plumbing is usually not seen, but I have pride in making my work look good.
