Just like everything else in a house, windows have a limited lifespan. If you’ve lived in your home for years or recently bought an older home, you might wonder when to replace windows.
What are the signs your windows need replacing? How often should windows be replaced? And why is it so important to keep track of their condition?
This guide will answer all these questions and help you determine the best time to upgrade your windows for maximum efficiency and comfort. Read on to find out more!
How Often Do Windows Need to Be Replaced?
Windows only need replacement every 10 to 20 years, though high-quality windows can last even longer with proper maintenance. The lifespan of your windows depends largely on the installation quality, maintenance, and material type. For example, here’s a breakdown of typical window lifespans:
- Vinyl windows: 10 to 20 years (premium ones can last up to 40 years)
- Wood windows: 30+ years
- Double-pane windows: 10 to 20 years
- Triple-pane windows: 15 to 30 years
- Fibreglass windows: up to 50+ years
- Aluminum windows: 20 to 45 years

Signs It’s Time to Replace Your Windows
If you don’t have a gaping hole in your window letting in a gusty breeze, knowing exactly when to replace windows might be harder. Some situations, like badly leaking or rotten windows, are obvious, while others like warped frames aren’t.
So, when should you replace windows? Here are the signs you should look out for:
You Have Drafts & Cracks
Beyond offering light and ventilation, windows are also meant to protect you from the outside elements. Canada, in particular, requires effective window seals to guard against harsh winter chills and summer heat loss.
Drafty windows and cracked glass diminish your heating and cooling efficiency, leading to:
- Higher energy bills
- Cold spots/hot areas
- Mould growth, wood rot, or wall damage (due to moisture infiltration)
- Increased noise pollution (i.e. whistling sounds when wind blows, reduced noise cancellation)
- Window condensation
- Visible gaps between the window frame and wall

Your Windows Don’t Open or Close Properly
Your windows should open easily, not stick or jam. If opening them sends you into fits of rage, it’s time to replace them. These concerns aren’t only a bother, they’re also potential security risks.
Damaged windows that don’t open or close properly create vulnerable entry points for intruders and can trap your family during emergencies. It’s enough reason to invest in window replacement.
Even if you don’t notice cold drafts, cracks, or warps in your current windows, a spike in your hydro bill can signal hidden window problems. Functional windows create an effective seal from outside temperatures, keeping warm air in during winter and hot air out during summer.
You know your old windows are failing when they no longer seal up your home as intended. In turn, your HVAC system works extra hard, which shows up directly on your monthly bills.
If you’re tired of asking, “How often should you replace windows?” we recommend choosing new ENERGY STAR-certified windows. These high-performance windows create a superior thermal barrier, significantly reducing energy costs while keeping your home comfortable year-round. Plus, they often pay for themselves through energy savings over their lifetime.

You See Visible Damage or Deterioration
In some cases, the answer to “when to replace windows” can be in your face. Physical damage ruining your windows’ function and curb appeal is a great sign that it’s time to get new ones. For example:
- Cracked, rotting, or warped frames
- Damaged weather stripping
- Foggy or cloudy glass
- Peeling paint or water stains
- Decaying or missing putty or glazing
- Sagging or warped window sash
- Cosmetic issues
Some of these may just be cosmetic and can be solved with repairs, but in many instances, you’ll need full replacement, especially if the windows are older than 10 years.
You Want to Renovate or Increase Your Home Value
A less serious but still relevant sign you need some fresh windows is if you’re remodelling or reselling your home. Windows can dramatically alter the look and feel of a room, both inside and out.
So homeowners who want to elevate their property’s overall aesthetic, curb appeal, and market value often consider upgrading their windows. Energy-efficient windows are particularly attractive to potential buyers, offering long-term savings on energy bills and a modernized look.
