Founded in 1861 in Washington, D.C., Thos. Somerville Co. was originally a brass and foundry known as National Brass Works and we continue to pride ourselves on delivering the highest quality goods and service and the best overall value to our customers.

This philosophy has helped us grow into a regional industry leader, distributing a wide range of plumbing, heating, and air conditioning supplies and solutions throughout the Mid-Atlantic United States.

We have evolved into our current state operating out of 20 trade locations, 9 retail stores, and a Central Distribution Center. A family owned business from the start, Thos. Somerville Co. is a privately held company who continues to run a customer-centric business.
