How long do replacement windows really last

How Long Do Replacement Windows Last?

Many of us don’t give our windows a second thought, but windows do a lot more than just let the sun in. They give us a view and keep out bad weather and trespassers, all while letting us enjoy the warm, fresh spring air. But the most important purpose of a window is in insulating our homes. When windows start to lose their purpose, we need to start questioning when the time is for window replacement.

So, when you have a window that isn’t holding up its end of the bargain, when do you decide to make the window replacement call?

Life Expectancy for Windows

Let’s first look at a window’s overall life expectancy. Now, depending on what kind of window you have, these will vary in terms of their lifespans. Keep in mind, these aren’t exact numbers but just rough estimates for reference.

  • Aluminum/Aluminum-Clad: 15-20 years
  • Double Pane: 8-20 years
  • Skylights: 10-20 years
  • Window Glazing: 10+ years
  • Vinyl Windows: 20-40 years
  • Wood Windows: 30+


If we reference the above table, it clearly shows that not all windows are created equal, and what may work for some may not work for you. If there are already noticeable issues with any of your windows, you may need to do a window replacement sooner than later.

The Two Most Common Reasons for Window Replacement:

If you are seeing fogginess or condensation, this means you have double pane windows. There is air, or inert gas, that fills in-between the windows and, if the seal is broken, moisture is allowed in, which gives that foggy, blurry look. 

There is a temporary fix using silica, to try and clear up the moisture but this is not a fool-proof fix.


Alternatively, if the window has lost its functionality, it may be time to schedule a window repair. The  window may have reached its end, showing its normal wear and tear sooner than later. Severe weather and extreme hot or cold temperatures are the most common causes for basic window failures. For the majority of the reasons for loss in functionality, they are unrepairable and will require calling upon a window replacement company.
