What affects the price
Replacing windows is a custom job, so your final bill depends on a few specific variables. The size and style of the window frames—like double-hung versus large picture windows—play a big role. Choosing energy-efficient glass coatings or adding decorative grids can also shift the total. We also look at the condition of your existing frames and whether the installation requires structural repairs to the surrounding wall. Your exact pricing is confirmed free on the call.
