At Window Nation, we know replacement windows. We’re third-generation window replacement experts who have been lucky to provide homeowners replacement windows, siding, and doors for over fifteen years. We opened our first showroom in Maryland in 2006, quickly growing to serve homeowners in cities across the country – and we’re not stopping there. We’re grateful for every homeowner who has trusted us to upgrade their most important asset: their home. We’ve learned a lot about home improvement over the years, but the most important thing we learned isn’t about window replacement. We learned the home improvement industry isn’t about offering the best windows, siding and doors; it’s about the relationships we build with our customers.

Windows questions, answered by experts

Impact windows can last between 10 and 40 years, depending on how much wear and tear they receive. This is roughly within the range for standard windows; standard windows tend to last between 15 and 50 years. You can extend your windows’ lifespans by performing regular maintenance on them and ensuring they are installed correctly.

Casement windows are more expensive than some other window types, such as single-hung or double-hung windows. However, casement windows are not the most expensive type of window. Bow and bay window costs tend to be the highest, because they involve multiple large windows that jut out from the exterior of the home.

The average lifespan for a casement window is around 20 years, but some higher-end casement windows with more durable frame materials can last up to around 40 years before you need to replace them. You’ll need to carry out routine maintenance and window cleaning—and, on occasion, casement window restoration—to extend the lifespan of your casement windows. But they tend to wear more slowly than windows with sliding sashes because the weatherstripping sees minimal friction.

If your windows are drafty, fogging up between panes, or hard to open or close, it might be time for a replacement. Unexplained increases in your energy bills, rotting frames, broken seals, and noticeable noise from outside can also indicate it’s time for new windows. In addition, if you find yourself frequently needing to repair your windows, it’s probably more cost-effective in the long run to replace them.

Window screens can help keep some heat out of your home, which is one benefit of using them in summer. It’s also the reason experts suggest removing your screens in winter—so it’s easier for the sun’s warmth to filter into your home. This will keep you cozier and potentially reduce your heating bills.
