Harvey Building Products (HBP), the No. 15 company on the ProSales 100, notified its customers today that Harvey's owners have sold the dealer to Dunes Point Capital, a private equity firm.

"As of Oct. 1, Harvey Building Products will operate under new ownership," company president Jim Barreira said in an e-mail from the Waltham, Mass.-based company. "The Bigony and Morrison families ... have decided that now is the right time for them to sell the majority of their ownership to Dunes Point Capital. And because they believe so strongly in HBP’s future prospects, the Bigonys and Morrisons will maintain a minority stake."

Based in Rye, N.Y., Dunes Capital emphasizes from its website's home page onward that it makes long-term commitments. It owns a number of firms that make products for residential and commercial construction, but Harvey appears to be the first LBM-style addition to its current portfolio.

"Going forward, we can expect an acceleration of the growth activities that made us what we are today--new branches, products, services and programs and processes," Barreira said. "And while we will continue adapting to capture business opportunities, we do not anticipate significant changes based upon our new ownership including facilities, product offering, marketing programs, and credit and payment processes. Our overall commitment to excellent service and quality products remains firmly in place."

Harvey posted $405 million in sales in 2014, all of it to pros. It manufactures its own windows and doors and sells other companies' siding, roofing, windows, doors, and decking.
