Atlanta, GA-based building materials distributor US LBM has acquired XO Windows — a regional supplier and installer of windows and doors, serving residential and commercial builders across the Phoenix and Las Vegas-Henderson metro areas.

Founded in 2008, XO Windows provides a wide range of product offerings, including vinyl, aluminum and specialty-shape windows, as well as exterior, interior and sliding glass doors, many of which exceed Energy Star requirements.

In a Jan. 20 news release, US LBM stated that Phoenix-based XO Windows is one of Arizona’s largest window distributors, with locations in Tucson and Henderson, NV. The Phoenix operation has been integrated into US LBM’s Arizona Building Supply (AZBS) division, led by Mike Dykstra, AZBS Market President. The Nevada locations joined US LBM’s Desert Companies division, led by Terry Ono, President, Desert Companies. XO Windows now operates in US LBM’s northwest and southwest regions.

“XO Windows has a strong leadership team and a high-performing, well-organized operation,” said Steve Short, Regional Vice President for US LBM’s southwest region, and Scott Richter, RVP for the northwest region. “They are becoming a strong partner for locations across our western regions and for all of us at US LBM.”

“We’re proud to welcome XO Windows to US LBM,” added US LBM President and CEO L.T. Gibson. “I’m confident this partnership will strengthen our ability to serve two of the strongest metro areas for new home construction in the country. I look forward to what we’ll accomplish together.”

Previous LBM acquisitions in 2025 included Calabash, NC-based Beach Window and Door on March 6; Pewamo, MI-based Goodrich Bros, announced on Feb. 6; and Nashville, TN-based Walker Lumber & Supply, announced on Feb. 4.

US LBM was No. 6 on MDM’s Top Distributors List for Building Materials/Construction.
