How Often Should You Replace Your Home’s Windows?

The U.S. Department of Energy estimates that heat gain or loss through windows contributes to 25%-30% of residential heating and cooling energy use.

You might say you're throwing money out the window when you have old or drafty windows. Your HVAC system has to work harder to keep your home comfortable, and your energy bills skyrocket. 

How often you should replace your windows depends on their age and condition. So, how do you know when it's time to replace your home's windows? Here are some key indicators to keep in mind. 

Your Windows Are Getting Old

On average, residential windows have a lifespan of around 15-25 years. After this point, the seals deteriorate and fail, which results in air leakage and moisture problems. 

The type of windows you have also affect how long they'll last. While single-pane windows used to be the standard option, they're not as energy-efficient as double-pane styles. 

Of course, this is only a guideline, and you may need to replace your windows sooner. Other factors affect the lifespan of your current windows, such as climate and maintenance. For instance, excess rain and seeping water can lift the seal and expose your window to moisture. 

There's Visible Damage

One of the most obvious signs you need window repair or replacement is when you see visible damage. Cracks, water seepage, pests, mold, etc., all affect the integrity of your windows. 

In some cases, you may only need to repair a window. However, when the damage is too extensive, you'll have to replace your windows. 

It's always good to get an expert's opinion. 

You Have Expensive Heating and Cooling Bills

Home heating prices are the highest they've been in years. Many families are already struggling to pay their energy bills. Households will pay an average of 12.7% more on home heating this winter compared to past years. 

Old windows also contribute to higher energy bills. Again, heat gain in summer and heat loss in winter cause many people to adjust their thermostats and pay more on their bills as a result. 

If you've compared your energy bills over the last few years and noticed a trend, it may be time to replace your home's windows. 

There are also other ways to find energy savings around your home, such as upgrading your appliances and adjusting your thermostat.

You See Condensation Inside Your Windows

If you have double-pane or triple-pane windows and notice condensation between the glass, it indicates a broken seal. When that air-tight seal deteriorates or fails, it causes air and moisture to leak inside your windows. It also means the insulating gas has escaped. 

At this point, replacing the window is your best option.
