As Solid as Our Name

The Granite Group has a proud tradition in the plumbing and heating wholesale supply business dating back to the turn of the last century.

Our roots can be traced to Central Supply Company, which originated in 1901 in Worcester, MA as a distributor of gas and steam engines and plumbing supplies. Throughout the years, we have expanded into new lines of business- hydronic heat, HVAC, pumps and water systems, industrial pipes and fittings, and design showrooms, to name a few. We have also expanded geographically, presently servicing all of New England and upstate New York.

Today, The Granite Group is ranked as one of the top 50 plumbing; heating and PVF wholesale distributors in the United States. The company has over 450 employees throughout its 26 locations and is dedicated to providing the best service to our customers in an effort to continue to build our business together.
