Window replacement in Clayton
Clayton sits right at the foot of Mount Diablo, a small town of mostly newer homes that still takes the full inland summer heat. Builder-grade and aging single-pane windows let the afternoon sun pour in and the AC run all day; dual-pane Low-E glass cuts the heat gain and the bills, and keeps the Diablo views clear.
We match the window to the house, pull the permit, install to code, and clean up before we go. Most Clayton homes wrap up in a day or two once the windows arrive.
