How Long Should Windows Last?

The lifespan of windows generally depends on the material they are made of and the climate you live in. For example:

  • Vinyl: These windows can last anywhere from 20-40 years. Living in an extremely hot or cold climate can cause the windows to warp, meaning they will need to be replaced more frequently.
  • Wood: While wood windows should last at least 20 years, they often require upkeep in order to ensure they’re protected from the elements and continue to work properly.
  • Aluminum: Aluminum windows require less upkeep than either vinyl or wood, meaning they are usually good for anywhere from 30-40 years.
  • Fibrex: Asher Lasting Exteriors uses Fibrex windows, which are composites made of natural wood fiber. This means it is extremely durable and long-lasting against damage, weather, and other issues. These windows will be good for 40 or even 50 years.

Why Replace Windows Instead of Repairing?

If you’re wondering, “Should I replace my windows or repair them?” there are several factors to keep in mind. In many cases, repairing your existing windows only provides a short-term solution for the larger problem at hand. For example, if your windows are letting in drafts, you can fix them until you can get them replaced. Performing home maintenance and replacing your windows will help increase your home’s energy efficiency so you don’t lose more money during the warm or cold months.

While replacing your windows is a much higher upfront cost, it will save you money in the long run, especially when you choose a durable window such as Renewal by Andersen that we install.

6 Signs You Need To Replace Your Windows

How often should you replace windows? There are many signs you need new windows that can help you determine when to upgrade your home’s operation and functionality. Noticing signs, such as drafts or condensation, can help you save thousands of dollars in potential damage and repairs. Some other signs that can help you answer the question “Do I need new windows?” include:

Drafts And Air Leakage

Drafts are often a clear sign that windows need to be replaced. Drafty windows let in cold or warm air, leading to your home’s HVAC system having to work overtime to compensate. Older windows lose their seal over time, leading to this air leakage. If you notice your windows leak air even when closed, it may be time to replace them.

Difficulty In Operation

If your windows are difficult to open or close, this can be a sign of needing to replace them. Jammed windows or windows that don’t stay open can cause many issues for your home, including:

  • Exposure to the elements
  • Added allergies from pollen getting inside your home
  • Decreased energy efficiency

If you’re questioning, “Should I replace 20 year old windows?” one way to know the answer to this is to look at how well they operate for your home’s needs.

Condensation Between Glass Panes

While condensation on the outside of your window is normal, if it happens on the inside or between the panes, this can point towards other issues. Condensation between the panes usually means that the seals on the windows are fading, which can lead to reduced insulation efficacy and the potential for mold growth.

Noticeable Damage Or Decay

Noticeable window damage or decay is one of the easiest ways to know that your windows need to be replaced. Cracks, rot, and warping all point towards needing to replace your windows. While damage is the easiest way to see that you need new windows, it also generally means that you need to fix this issue as soon as possible before other problems arise. For example, if your window is cracked, it can be easier for burglars, bugs, rodents, or water to get inside.

Increased Noise Penetration

Noise pollution and external sounds can start seeping into your home if your windows are old or have deteriorated. Windows are supposed to help block noise, but old or single-paned windows cannot do this well. Investing in newer, double- or triple-paned windows can help combat this issue.

High Energy Bills

Rising energy costs can be another sign of the low life expectancy of windows. If the seal on your windows has broken down, leading to increased drafts and other weather issues, you may notice your electric bill start to increase quickly. Installing modern windows can increase energy efficiency and lower your electrical costs.

Factors That Affect The Lifespan Of Windows

Once you know when you should replace your windows, you may also wonder, “How long are windows good for?” or “How long do replacement windows last?” There are many factors that can affect the lifespan of your windows, such as:

Material Quality

As mentioned earlier, the material of your windows can affect how long they last. Asher’s Renewal by Andersen Fibrex windows provide some of the best quality for long-lasting efficacy, whereas wood or vinyl might require earlier replacement.

Climate And Weather Conditions

Climate and weather can also affect the lifespan of windows. Living in colder environments with lots of snow can cause your window frames to bow or warp, while hotter weather often leads to increased condensation and leakage. It’s essential to remember this when assessing your windows’ durability.

Asher’s Renewal by Andersen windows provides durable windows that withstand the elements. 

Installation Quality

The installation quality of your windows can even affect how well they perform. If they aren’t installed properly, this can lead to issues with their seals, frames, and overall efficacy. Ensuring your energy-efficient windows are correctly installed is imperative, and Asher’s commitment to high installation quality means you won’t have to worry about improper installation issues.

Maintenance And Care

Regularly maintaining and caring for your windows is drastically important for their longevity. Some tips to ensure that your windows are cared for include:

  • Regularly cleaning your windows
  • Checking the seal and caulking around the windows every few months
  • Ensuring the tracks of the window let you open and close them easily
  • Replacing weather stripping
  • Cleaning the glass
  • Looking out for moisture, mold, or condensation
