How Long Does Glass in Windows Last?

For many homeowners, especially those who have purchased older homes, there is a common question about windows: how long does the glass in the windows last before it is time for replacement? The following considers the average lifespan of the standard glass window, signs that it is time to replace glass windows, and your options when it comes to new windows in your South Cook County, IL or Lake County, IN home:

Glass Is a Highly Durable Material

The good news is that of all of the materials out there, glass lasts longer than just about anything else. In fact, when it comes to windows, it is not really the glass that a homeowner needs to worry about so much as it is the frame. To be sure, while glass will usually withstand the tests of time – easily lasting more than 100 years – an insulating glass panel may suffer from a broken seal on its frame after years of heating and cooling, expansion and contraction. While the highest quality windows can last up to 50 years without the seal breaking, some windows will need to be replaced much sooner.

Signs It Is Time to Replace Your Windows

There are a few things that you can look for to determine whether or not it is time to replace your windows. Keep an eye out for:

  • Condensation. If condensation is forming on the inside of your window, it is a sign that the seal around the glass has a break. Do not go too long without replacing this – if you do, moisture can cause damage to the frame itself, and mold may even start to grow.
  • Drafts. If you notice that the windows feel drafty – i.e., you can feel cool air seeping through even when they are closed – it is probably time to replace them. Cold contracts and shrinks the glass, allowing for gaps in the seal that can allow cool air to enter your home, reducing your home’s energy efficiency.
  • Difficulty opening or closing. While this is not an issue with the glass, it is a sign that the tracks for your window are worn out and in need of replacement. If you are fighting with a window to open or close it each time, save yourself the headache and get it fixed.
