About Thos. Somerville Co.

Est. 1861
Since our inception over 150 years ago, Thos. Somerville Co. has prided itself on delivering the highest quality goods and services 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.
Founded in 1861 in Washington, D.C., Thos. Somerville Co. was originally a brass and foundry known as National Brass Works. From that foundation Thos. Somerville Co. has evolved into its current state operating out of 23 branches, 10 showrooms, and a Central Distribution Center. A family owned business from the start, Thos. Somerville Co. strives to operate customer focused branch operations. At Thos. Somerville Co., we know that excellent service is the key to our success. A lot has evolved over 150 years later, but one thing that remains the same is our philosophy for providing the best overall value to our customers. #TheSomervillePromise.
