JH Kelly has grown into one of the largest industrial mechanical contractors in the nation - and although the organization looks different from when Jack Kelly, Sr. first opened its doors in 1923, one thing still remains: the trust built on the job is the lasting measure of success.


JH Kelly is a fourth generation, family-owned construction firm that provides mechanical services to commercial facility owners while also acting as a self-performing industrial general contractor at process plants throughout Washington, Oregon, Idaho and Montana.

JH Kelly brings together great people and their abilities to plan and execute challenging projects – resulting in a loyal customer following.


Over the past 90 years, we have been fortunate to grow our business from a just dozen plumber shop in Longview, WA in 1923 – to over 1,000 craft and salaried employees today. Our company evolved by completing round-the-clock shutdowns at paper mills along the Columbia River and tackling tough turn-arounds for refineries in northern Washington and Montana.

We have grown alongside the¬†industrial and commercial markets and we’ve invested heavily in piping and electrical fabrication facilities, giving our company the edge in this dynamic, competitive marketplace.
