What Window Replacement Actually Involves
Window replacement isn't the same job as new construction. Your existing frame and siding stay put — the old sash and hardware come out, and a new insert window goes into the existing opening. Done right, it's a clean process: no drywall damage, no siding repair, and most homes get done in a single day for a handful of windows.

Every install includes proper flashing, insulation around the frame, and sealing to stop the air leaks that drove up your heating and cooling bills in the first place.
