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

Installing a bay window is more complex than a standard window replacement because it requires creating a seat board, a head board, and often adding a roof or support cables outside. The total depends on the size of the unit, the materials used, and the structural framing required.
