From the Pros: When do Windows Need to be Replaced?

June 1, 2023

Windows are a crucial part of any home, and they need to be replaced every so often. How often depends on a few things, such as the climate, the type of window, and how well it’s been taken care of. Generally speaking, most windows should be replaced every 10-15 years.

If you’re not sure whether your windows need to be replaced, it’s best to consult with a professional. A window specialist or contractor can help you determine when you should replace your windows and the best options for your particular situation. However, we’ll give you some tips as a homeowner to decide whether or not it’s time to take the plunge.

When do windows need to be replaced?

From our professional experience, most homeowners will need to replace the windows on their homes between 10 and 15 years. Of course, this varies depending on the type of window, how extreme the climate is, and how well they have been taken care of. Your windows may last longer or shorter depending on these factors, so it’s crucial to assess when they need replacing by looking at the condition of your windows and other circumstances in your home.

For example, if you live in a particularly harsh climate where severe thunderstorms, high winds, and hail are common, your windows may not last as long.

While the elements play a significant role when windows need replacing, there are other factors.

The factors that play into when windows need to be replaced.

Aside from a rogue baseball flying through your window and breaking it, the most common reason windows need to be replaced is when they are too old or worn out. Over time, even the most robust windows will deteriorate, resulting in cracks and scratches that let in unwanted elements like water, cold air, dust, noise pollution, etc.

Here are some of the more common factors that affect the lifespan of your windows:

  • WeatherUV rays, wind, temperature changes, and moisture can affect how long your windows will last. These can affect all aspects of the window, from the frame to the glass.
  • Normal wear and tear: Like everything else in life, windows are susceptible to normal wear and tear. Over time, the locks, frames, and glass can become worn down. This makes it harder to open and close your windows or making them more susceptible to breaking.
  • Improper installation: We see this more often than you’d think. If your windows were not installed properly, they may not last as long as they should. Improper installation can cause gaps and cracks that let in the elements and make opening and closing your windows more challenging.
  • Window type: The window type will also affect how long it lasts. Double or triple-paned windows have seals that may fail, and various frame materials will outlast others depending on the maintenance requirements.
  • Taking care of your windows: Adhering to your window’s maintenance requirements will ensure that they last as long as possible. For example, cleaning your windows regularly will help prevent scratches, and cleaning the jambs and jambliners will allow the window to move quickly.

How to know if your windows need to be replaced.

There are several ways to determine if your windows need to be replaced. The most obvious sign is when you can see cracks or holes in the glass. But what about the less obvious ways? Your windows may appear in good condition, but once you start looking for the signs, you might realize they’re not doing as good of a job as they were new.

Here are a few indicators to look out for-

  • If your windows are foggy or have water condensation between the panes. This is indicative of broken seals. The moisture is entering between the panes, which means your windows are not as energy efficient as they once were.
  • Difficulty opening or closing your windows. This could be that your jambs are dirty or something more catastrophic such as a warping frame.
  • Drafts come into your home when your windows are closed. Nothing will hike your energy bill like a drafty window. This could be from poor installation, rotten seals, or a warped frame.
  • Scraping or screeching when opening and closing your windows. This is most likely caused by dirt and grime creeping into the jambs. It could also be from normal wear and tear or a warping frame.

If you notice any of these signs when using your windows, it may be time to consider replacing them.

If you’re not sure whether or not it’s time to replace your windows, we recommend having a professional inspect them and help you make this decision. They see this kind of thing and can help you determine when it’s time to make that window replacement.

The benefits of replacing your windows.

Some of your windows might be displaying one of the signs we mentioned above. However, that doesn’t necessarily mean it’s time to replace all of them. There are some benefits to outfitting your home with new windows when the time is right.

One of the most significant and most dramatic advantages of new windows is improved energy efficiency. Replacing your old, drafty windows with new ones that are correctly sealed can help keep more heat or cold in your home and save you money on energy costs over time.

In addition to lower energy bills, you’ll be amazed at how much noise they keep out. If you live in an area with a lot of traffic or other loud noises, you’ll appreciate being able to close your windows and still feel like you’re in a peaceful oasis.

New windows also add value to your home should you decide to sell it down the road. Because they are such an essential part of any home, new windows can help increase the resale value when the time comes.

Finally, new windows can make your home look nicer. Old, outdated windows can make your whole house look tired and need some love. New windows will brighten your space and give your home an instant facelift.

How much does it cost?

There are so many variables regarding the cost of new windows. The size, number of windows needed, type of window, and whether or not you’re doing the installation yourself or hiring someone to do it for you (we don’t recommend this!) will all affect the final price tag. In general, you can expect to pay between $500 and $1000 for each window in your home.

The best way to get an accurate estimate for your particular situation is to contact a window professional. Many window companies offer free in-home consultations and will be able to give you a much better idea of what it will cost to replace the windows in your home.
