About Us
In 1884, Dennis Mahoney purchased a small sawmill from Art Pritchard. From those humble beginnings in Mattapoisett, Massachusetts grew Mahoney’s Building Supply. Over the next century, the employees and customers of Mahoney’s Building Supply would weather economic depressions, two world wars, and countless changes in their lives, but would also come to know Mahoney’s as a consistently trustworthy supplier of quality products and building materials.
Changing with the times, Mahoney’s would continue to evolve, at times selling ice and coal as well as building materials and garden supplies. Today, Mahoney’s Building Supply is a leading provider of building materials and contractor service in the area. Serving customers from Cape Cod to Providence, Mahoney’s employees continue the company’s legacy of exceptional service.

From our offerings as an Andersen Circle of Excellence dealer to our staff of professional kitchen and bath designers, from our fleet of next-day delivery vehicles to our warehouse of high quality, hard-to-find boards and mouldings, Mahoney’s Building Supply is positioned to supply the professional builder and remodeler with the materials and services they need, and local homeowners with the friendly, knowledgeable advice they deserve.
