Straight answers

Buying replacement windows

What makes a window custom?

The frame is built to the approved width and height with a selected operation, frame depth, glass package, finish, grid pattern and installation method. Manufacturing limits still apply to every combination.

Is an insert replacement always less expensive?

Not always. It can reduce finish work when the existing frame is sound and properly sized, but a damaged, leaking or unsuitable frame may require full-frame replacement.
