What affects the price

When you look at the price of impact windows, several factors shift the final number. The size and quantity of your window openings are the biggest drivers, as is the specific style—like single-hung, casement, or sliding doors. You will also see price differences based on the type of glass coating you choose for energy efficiency and the thickness of the aluminum or vinyl frames. Added hardware features or custom finishes can also adjust the bottom line. Homeowners typically see projects start in the mid-range of a few thousand dollars, but exact pricing is confirmed free on the call.
