Like most things, windows have an expected useful life. Even professional installations and the highest quality brands eventually break down or weaken. Residential windows have an average lifespan of about 15 to 20 years. If you maintain your windows well enough and cover them accordingly with blinds, they may last beyond the 20-year mark, but that’s when you need to start thinking about having them replaced.

Signs You Should Replace Your Home Windows

Age is not the only indicator that’s it’s time to replace your windows. Here are some of the signs that you need to replace your windows or windows on your patio door:

  • High energy bills: If your windows begin to fail, you’ll start to notice higher energy bills. And that’s a common sign that your windows are leaky and inefficient. Something to help this would be to get drapes or blinds
  • Drafts and other comfort problems: If you have old single-pane windows, you’re likely to experience uncomfortable drafts. However, even newer windows can develop broken seals and air leaks, resulting in home comfort problems.
  • Rotted or warped window frames: Wooden windows are especially susceptible to rotting and warping, which can result in flooding, air leaks and eventually complete window failure.
  • Difficulty closing or opening windows: Over time, single- and double-hung windows will often become difficult to operate. The foundation settles, or the windows become unbalanced, causing the window to either fall close too easily or become jammed.
  • Condensation between the panes: If you have double-pane windows, condensation between the panes is an indication of a broken seal, allowing moisture to get between the panes. As a result, the window becomes inefficient, so you should have it replaced.
