US LBM today announced it acquired American Masons and Building Supply, a Hartford, Conn.-based distributor of wallboard, steel framing, insulation, acoustical, and masonry supplies.

The company will be folded into another US LBM subsidiary, East Haven Builders Supply. Former American Masons owner Dave Westerman will continue to lead his company's 20 employees under the new ownership.

"We are thrilled to become a part of East Haven Builders Supply and the US LBM team," said Westerman. "Partnering with US LBM will enable us to provide our customers enhanced product offerings and improved levels of service." 

"American Masons demonstrate US LBM's commitment to grow its specialty products offering," said US LBM president and CEO LT Gibson. Earlier this year, we partnered with Feldman Lumber and Wallboard Supply Company, both leading distributors of wallboard, steel studs, insulation, and acoustical products in the Northeast. American Masons further strengthens US LBM's position growing wallboard and related category sales to more than $150 million."

This is the fifth major acquisition this year for US LBM. In November, the company purchased K-I Lumber & Building Materials in Louisville, Ky., and Wallboard Supply in Londonderry, N.H. In May, US LBM acquired the Desert family of companies, and in August, US LBM, which ranked 13th on the 2014 ProSales 100absorbed the No. 29 company on that list, Feldman Lumber.
