What affects the price

Replacing windows involves a few variables that influence the total project cost. The biggest factor is the material you select, such as vinyl, wood, or fiberglass, as well as the style of window, like double-hung versus casement. The condition of your existing frames matters, too; if there is hidden rot or water damage, that requires extra labor to fix. Choosing triple-pane glass for better insulation or adding decorative grids will also shift the final number. Your exact pricing is confirmed free on the call.

About this service

The cost to install a window AC unit depends on the size of the unit, the weight capacity of your window frame, and whether any structural modifications are needed to secure it safely. If the window frame is rotted or the opening is an odd size, the labor involved will increase the final bill.
