ProBuild, which just 12 months ago acquired Big Buck Building Centers in Racine, Wis., gave notice to the state of Wisconsin Wednesday that it will close the operation effective Sept. 20. A total of 42 workers will be affected, some of whom might be offered jobs at other ProBuild facilities in Wisconsin, a company spokesperson said today.

ProBuild purchased Big Buck on July 1, 2008, in a deal that brought it a lumberyard, truss plant and millwork facility capable of serving both the Chicago and Milwaukee markets. The announcement then quoted Valerie Hansen, Big Buck's CEO and the third generation of her family to run the lumberyard, as saying "ProBuild will provide Big Buck with significant long-term growth opportunities."

But a spokesperson for Denver-based ProBuild told ProSales today that efficiencies gained at some of ProBuild's 10 other Wisconsin yards "allow us to be more efficient in that Racine market."

"We're always shuffling yards, in good times and bad," the spokesperson said.

ProBuild is the No. 1 company on the 2009 ProSales 100, with total sales in 2008 of $4.4 billion, 87% of them to pros.
