How Long Should My Windows Last?

If you purchased your windows from a reputable brand, and had them installed by professionals, you can probably expect to get a solid 20 to 25 years out of them. Even longer, if they’re kept in good shape. But it isn’t uncommon to walk into a major retail home improvement store, and find windows with a little price tag and a guarantee of no longer than seven years.

Some of these brands can last as long as 15 years, if you’re lucky. Others disintegrate after only 5. What this means is that eventually you’ll be spending money again anyway to replace your windows, and sooner rather than later. It’s best to do it right the first time.

Windows can be pricey, so opting for longer-lasting, high quality windows, will prevent frequent replacements, and is the key to saving yourself money in the long run.

If you’ve just realized it’s time to upgrade your windows, here’s what you need to keep in mind:


The two most common materials on the market for windows are vinyl and wood. Middle-grade vinyl can last around 15 years, while premium vinyl can last for approximately 20 to 25 years. The difference between the two is titanium dioxide.

Titanium dioxide within vinyl windows prevents warping, cracking, and peeling, helping the windows maintain their structural integrity over time.


Having windows properly installed is critical for extending their durability. Unless you recruit professional help for window installation, not only will the lifespan of your windows be significantly lowered, but your utility bill will skyrocket as well.


Windows exposed to bright sunlight are more prone to damage than those partially covered by shades. This is because the UV rays, and heat from the sun, can warp the materials over time. This especially is the case if the window quality is poor to begin with.
