How Long Should My Windows Last?

When the time comes for you to replace your windows, you need to consider a few things:

  • The quality of installation
  • The quality of the ones you plan to purchase (i.e., brand, materials, etc.)
  • How well is your house protected from the outside elements (i.e., what’s your insulation like)

Since new, replacement windows are a purchase you don’t want to spend money on repeatedly, you need to be mindful of all the relevant window criteria. So, here are some questions we have answered to help you understand a few relevant aspects of your window durability:

How Long Can I Expect My New Windows to Last?

Generally speaking, you can expect your windows to last approximately 20-25 years if you purchase them from a reputable brand and have them installed by professionals in the field. If you keep them in good shape, they could last even longer. However, specific brands don’t offer a guarantee for longer than 5, 7 or 15 years.

What Does the Lifespan Depend On?

There are a few factors you should pay attention to. Three significant factors you want to take into consideration when opting for a new set of windows are:

  • Materials
  • Insulation
  • Weather conditions


Two most common window materials you’ll find on the market are vinyl and wood. Each of the two has their benefits and downsides.

Middle-grade vinyl windows can last around 15 years, while premium vinyl windows can last for approximately 20 or 25 years. The difference between the two is in titanium dioxide within the vinyl that prevents warping, cracking, or peeling, while helping them maintain their structure stable over the years. It isn’t uncommon to find windows with a guarantee no longer than seven years; these types usually come with a little price tag and come from big box home improvement stores.

Wood is a commonly used material for doors and windows due to their long durability and ease of maintenance. However, wood versions are prone to rapid deterioration (they chip, peel, and rot) unless adequately taken care of. They tend to be considerably more expensive than vinyl windows.


Proper installation one of the crucial elements for the extended durability of your windows. Unless you rely on professional help for installation, not only will the lifespan of your windows be significantly lowered but your utility bill will skyrocket as well.


Among plenty of factors that impact the lifespan of a window, the weather is one of the crucial ones. Windows exposed to the bright sun are prone to last shorter than those partially covered with shade. Their durability will be jeopardized even more if the original window quality is poor.
