The summer heat clearly hasn’t fazed SRS Acquisition, the McKinney, Texas-based specialty products dealer that arguably is the fastest-growing LBM operation in the nation. Since early May, SRS has opened new, greenfield locations in Louisville, Ky.; Modesto, Calif.; Mansfield, Texas; Huntsville, Ala.; and Herndon, Va. But Beacon Roofing Supply isn’t far behind. It plans to acquire Cassidy Pierce Co., a Pittsburgh-based building products distributor with six locations in the area and approximately $52 million in sales.

Other operations are expanding, too. By now, Builders FirstSource plans to have opened a distribution center in Clarksville, Tenn. Last month, Galliher & Huguely of Washington, D.C., celebrated the grand opening of a new showroom and design center in Chevy Chase, Md. Brian Roberts, who oversaw the multi-year effort that led to the branch’s opening, will serve as the store’s general manager. Donna Godwin has been hired to be director of design services. The showroom will emphasize cabinetry—a first for Galliher & Huguely—as well as countertops, cabinet hardware, windows, interior doors, and, eventually, decking.

Elsewhere, Koopman Lumber will buy Westborough (Mass.) Paint. as well as turn the former property of Village Lumber in town into a full service lumber and hardware center.

Also, Milford (N.H.) Lumber reopened a showroom in Bedford, N.H., that was damaged by fire in 2009. Central Network Retail Group opened a new location in Gautier, Miss., under its NFL Home Center brand name. The store is at the site of the former Coast Building Supply.

York, Maine, is the new home for Greenovations Eco Building Supply, which relocated from Portsmouth, N.H., and Concord (Mass.) Lumber celebrated in May the grand re-opening of its location.

But that growth ledger is nearly offset by the number of dealers that have shut their doors or soon will. Among those are Babcock Lumber, Ruskin, Fla.; DeCou Lumber, Atascadero, Calif; J.M. Parker & Sons, Supply, N.C.; J. Bruce Barnes Lumber, Crozet, Va., Hoyt Lumber, Upland, Calif.; and Mill Valley (Calif.) Lumber. In addition, Lumber Products Inc., based in Tualatin, Ore., has filed for bankruptcy-law protection from creditors and planned to lay off 65 workers, including its chief financial officer and at least one vice president.
