How Often Do You Need To Replace Windows?

Windows are an integral part of any home, but as time progresses, they can get worn, damaged, or discoloured. So, many homeowners ask about the right time to consider a replacement.

To ensure that your windows are in good working condition, there are several factors to consider, both in terms of maintenance and repairing or replacing them. While some things are very obvious, such as broken panes or frames, other signs are subtle and can hint at a growing problem, so it is essential to check for these signs to avoid bigger problems down the road.

So how often should you replace your house windows? Let’s go over how often to replace windows and what kind of windows you might consider.

How Often Should Windows Be Replaced?

On average, the lifespan of windows ranges between 15 and 30 years. However, depending on the quality of the original installation, the quality of the materials used, and the local climate, the functional life of a window can be reduced to ten to fifteen years. That being said, if your windows start causing problems, you should not delay looking at potential replacements.

Here are some warning signs that it might be time to install new windows.

How To Know When To Replace a Window

Especially as your windows get older, it is important to inspect your windows regularly to check for wear and tear, cracks, leaks, and more. Some of these issues may seem small but could be the sign of a bigger problem or turn into one if not taken care of right away.

So, how often should windows be replaced? There are many factors to consider.

Window Replacement

Cracks and Chips

Windows and frames can develop cracks and chips over time. This could be due to age-related wear and tear, elements such as rain, snow, or wind, among other things. Cracks and chips can grow larger over time and affect the window’s structural integrity leading to lasting damage to the window unit. 

Leaky Windows

Once you notice leaks, it is time to replace your windows. Any moisture entering the house is a sign of a problem with the seals, which may be damaged or worn out. This should be checked, and if a repair is not possible, you should replace the window to avoid further water damage.

Condensation Buildup

Another sign of a cracked or broken seal is condensation building up on the inside of your windows or between the window panes of your double- or triple-pane windows. A damaged seal allows moisture to seep into the window and/or frame and can lead to lasting damage to the frame and window. If you have wooden windows, moisture can cause the frame to rot and lead to more damage. In these cases, you should consider polyvinyl or aluminum frames for more durability.

Over time, moisture exposure can also lead to mildew and mould around the windows and even inside the walls. It is important to note that even if a visible mould patch may be small and not cause any health problems, it might be a sign of bigger issues. And if you or a loved one suffer from allergies or asthma, mould and mildew can have serious consequences.

If your window has gas, such as argon or krypton, between the panes and you notice condensation, it can also be a sign of the gas leaking. If this happens, you should consider replacing the window unit.

Glass Damage

A cracked or broken window pane is a serious issue that you should address immediately. It is not only risking outside elements such as wind, rain or snow to enter your home but also is a safety hazard that can lead to personal harm.


An incorrect installation or damaged seal can lead to drafts entering your home. Not only is a cold draft in winter an inconvenience, but it also can lead to higher utility bills as your thermostat will have to battle against the lower temperatures. In the summertime, damaged seals can lead to vermin or insects entering your home, such as ants.

The best time to notice drafts coming in is during winter, so replacing your old windows during winter is a good option to eliminate the draft and increase the comfort of your home.

Replacing a faulty window can also lead to savings on your energy bills as you will not have heat or conditioned air escape through the cracks.

Choosing The Right Type of Windows

It is critical to ensure that new windows are compatible with existing window frames in your house, so it is best to consult a professional at Eco Choice Windows who can help you figure out the correct type of windows for your home. Here are some tips for choosing the right kind of window:

  • Look over the installation plan for your home.
  • Look for windows that are made from durable materials such as polyvinyl or aluminum.

  • Avoid using wood, especially if you live in an area with a high risk of forest fires or strong exposure to the elements.
  • Check your city’s regulations regarding the thickness and size of windows. This is critical to get approval for your building permit.

Things To Consider

Windows can be expensive to purchase and install, so there are some crucial factors to consider when choosing a product to ensure that it is energy-efficient, durable and give you a good return on investment.

Your Home’s Architecture

Your home’s architecture can have a big effect on which type of windows to choose. Depending on the age and structure, you may be limited in which types of windows you can use.

Another factor is the requirements of your home. Depending on if your window faces the sunnier or shadier side of your home or if it might be more exposed to wind and rain could warrant looking into different window types.

  • If there are any leaks, fix them right away.
  • Be mindful of the weather conditions and open windows when it is safe to do so.

How Long Should Replacement Windows Last?

Windows typically last anywhere between 15 and 30 years. Depending on the climate, a realistic average is about 15 to 20 years.

What About Older Windows?

Old windows can be a major contributor to your energy bills. Old seals can deteriorate and crack, leading to air and moisture entering your home, which can lead to higher energy consumption. They also can be the source of additional damage to your home, such as water damage, mould or mildew. An old, outdated window can also be a safety issue, as older windows and panes are easier targets for potential home invaders. Newer polyvinyl windows are generally more durable, stronger and secure.

Updating your windows can increase the comfort of your home, elevate the value of your property and also add some nice curb appeal. Replacing windows ranks high on the list of real estate agents and professional renovators, so they yield an excellent return on investment.


While the range of 15 to 30 years is large and far away, you should not put off taking the time and effort to find out about the options for new windows until problems with the old windows arise. 

As your windows are aging, it is vital to check them regularly for cracks or drafts and monitor your energy bills to see if there are any unusual fluctuations which could be caused by deteriorating windows.
