What affects the price
Replacing your windows involves a few moving parts that shift the total. The biggest factor is the frame material—vinyl is usually the most budget-friendly, while wood or fiberglass typically runs higher. You’ll also see price changes based on the type of glass, like double or triple panes, and any specialized coatings for energy efficiency. The number of windows, the complexity of the installation, and whether you need custom sizing will also play a role in your final quote. Exact pricing confirmed free on the call.
