ProBuild announced today it has reached an agreement to buy some of the assets of Chopp Lumber, located in the Washington suburb of Waldorf, Md., and will open a new millwork facility in San Antonio.

"These transactions give ProBuild an increased presence in two of the top 20 housing markets in the country, both of which analysts predict will see significant growth in the next several years," the Denver-based company said in a news release.

The former Chopp (pronounced "chope") facility in Waldorf, 23 miles southeast of the District of Columbia, will supply trusses, wall panels and lumber to residential and commercial customers in the Washington metro market and southern Maryland. ProBuild also augmented its service in metro Washington's western and northern segments in March when it opened a components manufacturing facility in Winchester, Va., 70 miles west of the capital.

The new millwork facility in San Antonio "enables ProBuild to serve the market more quickly and efficiently than had been the case from its millwork operation in Austin," the company said.

ProBuild's announcement came the same day that it lost its position as the biggest construction supply company on the ProSales 100. The former No. 2, ABC Supply, jumped past ProBuild by acquiring Bradco Supply, the former No. 4 firm on the list.
