What affects the price

Replacing windows involves several variables that change the final bill. The size and style of the window are big factors; fixed glass usually costs less than units that open, like double-hung or casement styles. Your choice of frame material—vinyl, wood, or fiberglass—also shifts the number significantly, as does the glass package you choose for energy efficiency. The complexity of the installation matters too, especially if there is existing rot or if the home needs structural work to fit new frames. Exact pricing confirmed free on the call.
