What affects the price

Replacing your windows involves several moving parts that change the final bill. The biggest factor is the frame material, as vinyl tends to be more budget-friendly while wood or custom fiberglass options sit on the higher end. You also have to consider the glass packages—things like double versus triple panes or extra coatings for energy efficiency can shift the cost. The complexity of the installation matters, too, such as whether your frames need repairs or if you are switching from a standard window to a bay or bow style.
