Most properly installed residential windows will generally last 15 to 25 years before requiring a replacement. The materials that make up each window will usually last much longer (up to 50 years), but home windows are about function as much as they are about aesthetics, view, insulation value, ease of use, and security.
Note: In this guide, we are not concerned with a brand new, full window installation which normally includes building frames where each window is hung, or installed. The costs are similar to window replacement project and there is much overlap in the work that each project entails, but our focus is on the replacement of windows, their costs, the factors impacting those costs and their pros and cons.
Pricing Information – Part 1
Window replacement projects tend to be fairly basic in terms of planning because the frame will likely determine the material of the updated windows. Wood windows in wood frames, vinyl windows in vinyl frames. Yet, types of panes (glass), along with considerations for energy efficiency and potential needs for repair make it so an average cost for replacement only goes so far.
The national average cost for a window replacement is between $500 and $850 per window installed, depending on your home’s location and other variables. The price can range from $450 to $1,450, which accounts for much variation in material type (from highest to lowest: wood, fiberglass, vinyl), window size, window brand (Andersen, Pella would be most expensive brands), and differences in pricing from company to company. More often than not, the more windows you purchase for a single project, the less you will end-up paying on a per window basis.
How a Window Style/Type, Size and Materials Impact Costs
Double hung windows are what most residential homes have. These are characterized by having sashes on both the upper and lower and thus both can slide vertically, up and down. Depending on the material and brand of the window, the average cost can range from $300 to $850 per window.
