How Long Do Windows Last? A Basic Guide for Homeowners

According to the EIA, heat loss through residential windows accounts for up to 30% of heat losses in your home. More heat loss means you’ll have to use your HVAC more, which in turn means higher electricity bills.

It follows that you should look at your windows if you want to save money and lower your home’s energy footprint. Are your windows due for an upgrade, and how long do windows last anyway?

Keep reading for the answers you need about replacing your home windows.

How Long Do Windows Last on Average?

Most times, the frame of your window will outlive the glass, and the lifespan of windows varies from 15 to 30 years depending on the types of windows you have.

This is what to expect:

Wood Windows

Since there are many types of wood used to make windows, their lifespan varies considerably. Most wood windows will last up to 20 years or more if you maintain them regularly.

It’s important to treat your windows against wood rot and insects like termites if you want them to last.

Aluminum Windows

Economical aluminum windows can last up to 25 years. They’re a lightweight, versatile type of window, but they are prone to wear and tear.

Cracks, dents, and scratches are some of the more common issues with aluminum windows.

Fiberglass Windows

Fiberglass is a durable material, so you can expect windows made from this substance to last up to 50 years.

You’ll pay a higher cost upfront than for most other types of windows, but you won’t need to consider replacing windows any time soon when you choose fiberglass frames.

Vinyl Windows

Vinyl windows offer a cheaper, low-maintenance alternative to wood and can last for up to 40 years. They’re built with non-corrosive compounds that can withstand humidity and won’t warp if they get wet.

Other Factors Affecting Your Windows Lifespan

Regardless of which window styles you prefer, it’s important to work with a window and door installation company that’s prepared to back up its work with lengthy warranties.

Longer warranties are a good indication of high-quality materials and expert workmanship.

The climate in your area can also cause your windows to wear out sooner. Intense heat can cause cracks and discoloration, while extreme temperature variations can lead to warped window frames.

Signs It’s Time to Replace Your Windows

If you’re shivering inside or your electricity bills are sky-high during the winter months, there’s an excellent chance you need new windows.

Leaky, cracked, or damaged windows let hot or cold air blow in and out of your home, so your HVAC must work overtime to keep your interiors comfortable.
