Brentwood Machine Sales, founded in 1966, started as a home-based used equipment business. In 1970, the business moved to a retail store, incorporated in 1974 and acquired the Jet and Makita franchises. It soon added other manufacturers such as DeWalt, Milwaukee, Porter Cable and Powermatic to provide equipment to builders and general contractors. The company expanded to a 14,000-square-foot showroom and is headquartered in Brentwood, N.H.
