ProBuild Holdings will open new locations in Orem, Utah, and Winchester, Va., the nation's biggest LBM operation announced today.

The Orem location will occupy the site of a former drywall store owned by Capitol Building Materials, a division of L&W Supply. It will begin with nine employees and be ProBuild's fourth location in the Beehive State. The facility also will have chain of custody certification from the Forest Stewardship Council. That will enable it to provide lumber to builders seeking to earn points under the U.S. Green Building Council's LEED system.

The 18-acre Winchester location used to be opered by Glaize Components, a maker of trusses, panels, and I-joists. Like Glaize, ProBuild will manufacture those components as well as operate a full-service lumberyard serving the Baltimore/Washington metropolitan market.

"We continue to see opportunities where we can expand into new markets to better serve our customers," said Michael Mahre, who was just announced Wednesday as Denver-based ProBuild's senior vice president of corporate development. "These new locations are great instances where we can bring the market-leading value of ProBuild's products and services to serve strong and growing markets."

"We see great potential in these markets," added Russ Kathrein, president of ProBuild's northeast region. "With the addition of Winchester, we will be able to better meet the growing needs of our customers with our complete line of products and services."

ProBuild has announced a number of facility openings (see ProSales' list) and closings (list) in the past six months and reports it has more than 470 facilities in 42 states. It was the No. 1 company on last year's ProSales 100, and is likely to do so again this year with reported 2009 revenues of $3.2 billion.
