The average lifespan of windows ranges from 15 to 20 years, but they can last up to 50 years when carefully maintained. These openings naturally degrade due to normal wear and tear, but there are several other factors impacting their longevity and durability.
Let’s take a look at those factors and the signs it’s time to replace windows.
How long are windows good for? This depends on their materials, the local climate, and maintenance, among others. Not all window types have the same lifespan due to the following factors:
Window frame materials don’t just determine insulation and costs—they also tell how long windows can last. There are four main types of material for window frames:

Ontario’s extreme climate affects the lifespan of windows. The sudden changes in temperature cause stress on the window frame and seals, making them brittle and vulnerable to cracking and warping.
Weather conditions also play a part in this; harsh UV rays, strong winds, and high-pressure storms can damage the window frame and seal.

When window seals are compromised, moisture can seep inside the window frame material and become susceptible to mould growth. This can lead to rotting, warping, or expanding for highly absorbent wood frames.
Windows can last up to 50 years when maintained properly. Cleaning the frame, lubricating operable parts, and checking window seals regularly will go a long way in prolonging the lifespan of windows.

A window replacement is necessary when your windows have exceeded their lifespan and show visible signs of damage. See the telling signs you need to replace your windows below:
If you can feel the air around your windows even when closed, it’s time to get replacement windows. Drafty windows are caused by poor installation, a broken seal, cracks in the caulking, and more.
Temporary solutions like caulking or weatherstripping can help stop air leakage, but the best thing you can do is replace any drafty windows and doors. Not only will drafts cause drastically fluctuating temperatures in your home, but also cause your HVAC system to work extra hard to keep up with the changes, increasing your energy bill.
Older windows lack the insulation and proper fitting necessary to keep your home comfortable. As a result, your heating or air conditioning systems use more energy to meet your needs, costing you a fortune. If you notice that your energy bill has suddenly increased, it’s a sign that you need to replace windows.

Condensation forming outside the window is fine. But if you notice condensation or frost accumulation inside or between the glass panes, then you can be sure they’re no longer providing the protection they should. This happens when moisture droplets travel into the seal gaps and form fog between the panes—something you can’t easily fix.

You shouldn’t hear outside noise after closing your window. When noise leaks inside your home, your windows aren’t providing the acoustic insulation they’re meant to have. Getting replacement windows is the first solution to prevent outside noise pollution from seeping into your home.
If your windows are damaged or not meeting your standards, they can ruin your home’s curb appeal. Address this issue by replacing windows and customizing them to your style. Manufacturers produce chic, modern windows that are built to last long and make homes more energy efficient.
Replace your windows once you’ve noticed visible damage on window frames. Chipping, water stains or any other signs of deterioration on or around the window means they may no longer be effective. Cracked or warped frames are a lost cause since there’s no other way to repair them than to replace them.
Opening and closing windows shouldn’t be difficult; they should swing smoothly without making any sound. If you can’t close your windows properly, you’re compromising the safety of your home as you won’t be able to lock them—a dead giveaway you need to replace your windows.
Incorrect installation is one of the most common causes of window inoperability. This leads to balancing issues, making the windows hard to move. Rusting or rotting can also be a reason for inoperability, especially with wooden windows.
Single-pane glass is extremely common in older homes. Homes built before 1970 have a good chance of still having their original windows with single-pane glass.
Today’s standard is the double and triple pane windows; they’re more energy efficient and offer greater protection from the sun’s rays. If you’ve noticed that your window treatments, furniture and walls have started to fade due to UV rays, modern replacement windows are the best solution.
