Window Repair & Sash Fabrication in Northern Illinois
We repair and restore Rockwell, ROW, Wenco & Windsor windows — fabricating custom replacement sashes that save you thousands over full window replacement. Family-owned in Diamond, IL since 2009. Authorized Cardinal IG® dealer.
From a Coal City Garage to a Full Fabrication Shop
We started in a garage in 2009 with one simple idea — that windows worth saving shouldn't have to be replaced. Today we operate out of a climate-controlled facility in Diamond, IL, hand-crafting replacement sashes for Rockwell, ROW, Wenco, and Windsor windows.
