When Should I Replace My Windows?

The typical lifespan for residential windows is 15 – 20 years. Properly maintained windows should last longer. If your home’s windows are over 20 years old, they’re not aesthetically pleasing or have obvious signs of damage, it may be time to replace them.


Other signs to replace your bay windows 

  1. They are a security risk, if the frames are loose or sagging it may be that the window has weakened and is susceptible to easy forced entry. 
  2. They’re not energy efficient or your home is too cold. This could be a sign that the windows have not been fitted properly and it’s allowing a draught or heat to escape. 
  3. They’re not keeping sound out. Again, this could be that the windows are not installed properly or are single glazed.
