How Long Do Windows Last? Signs It’s Time to Replace Them and What to Expect

| August 18, 2024

Are you planning to install replacement windows? If so, you’re probably looking for the longest-lasting windows that will make your investment 100% worth it. So, how long do windows last?

Windows usually last 15-30 years, although some innovative windows like those from Magic can last 40+ years. These numbers are established based on several factors, including frame and insulating materials. Furthermore, windows will only reach (or outlive) their lifespan if maintained properly.

As such, this article will help you understand the lifespans of different window types and when to consider replacements.

Key Takeaways

  • A window’s lifespan varies depending on the frame material: vinyl (20 years), wood (over 20 years with proper maintenance), aluminum (30 years), and fiberglass (30-40 years). Magic’s Hybrid Fusion Frame windows last 40+ years.
  • Other factors affecting a window’s lifespan include insulating materials, climate, installation quality, and maintenance.
  • Signs indicating that you need to replace your windows include drafts, condensation between panes, difficulty in operation, and visible damage.

How Long Do Windows Last?

On average, windows last between 15 and 30 years. Some windows featuring innovative technologies – Magic windows, for example – can last 40 or more years. Vinyl windows last approximately 20 years, while aluminum and fiberglass windows can reach a lifespan of 30 years. Wood windows have an average lifespan of 20-30 years as they’re highly durable, but only if maintained properly.

As such, two crucial things influence how long windows last: frame and insulation materials and maintenance.

However, there are other factors that influence a window’s longevity, including the installation quality, the climate, how often the window is used, high humidity levels in the house, and others.

Furthermore, guiding yourself solely based on a window’s longevity is not the best way to choose windows. For example, aluminum is a durable, long-lasting material but not energy-efficient, so you may eventually spend a lot on energy bills.

How Long Do Vinyl Windows Last in Canada?

On average, vinyl windows last approximately 20 years as long as they’re properly maintained. However, Canadian weather conditions can shorten their lifespan.

These windows are praised for their low thermal conductivity, which means they’re energy-efficient. In addition, they’re low-maintenance and effective at repelling water. Vinyl is also a budget-friendly material.

However, if you live in a climate with extreme weather conditions, you should reconsider installing vinyl windows. They won’t withstand extreme temperature fluctuations and will start warping or cracking. This, of course, will significantly shorten their lifespan, so you may notice signs of wear and tear only 10 years after installation.

What Is the Life Expectancy of a Wood Window?

A wood window lasts, on average 20-30 years. However, if maintained properly, wood window frames can last much more, sometimes reaching a lifespan of 50 years. The key here is maintenance – to make sure they do last so long and do not peel, chip, or rot, you should never skip any steps in your wood window care to-do list. And let’s not forget that wood can get infested with pests, so preventing this is an extra task on your maintenance routine.

Furthermore, even if the frame may last long enough, other window parts can fail over time, including the glass, the insulation, and the hardware.

How Often Do Aluminum Windows Need to Be Replaced?

Aluminum windows are praised for their durability. They usually last approximately 30 years with regular maintenance. They are less prone to warping and rotting compared to vinyl or wood windows, making them a reliable choice for many homeowners. However, aluminum has a high thermal conductivity. In fact, vinyl’s thermal conductivity is 700 times better than the thermal conductivity of aluminum windows!

In other words, if you live in a region like Ontario with hot summers and cold winters, aluminum is definitely not the best choice. You may save some money over time thanks to their long lifespan, but you’ll eventually spend a lot on energy bills because your windows will offer poor insulation.

How Long Do Fiberglass Windows Last?

Fiberglass windows last between 30 and 40 years. They are more expensive than other windows, but the material is rot-resistant and extremely durable, surpassing the durability of wood or vinyl. On the other hand, fiberglass windows need regular maintenance. In addition, it’s impossible to weld fiberglass frame corners, which can lead to water leakage over time.

What Type of Window Lasts the Longest in Canada?

Magic windows featuring the Hybrid Fusion Frame technology last the longest in Canada – at least 40 years. Our frames have an aluminum and steel skeleton, which is wrapped in vinyl. As such, we’ve combined the advantages of these three materials (the incredible strength and durability of aluminum and steel and the high performance of vinyl) to create a window frame material that’s stronger, more stylish, and more efficient than anything else on the market.

We believe in our windows, which is why all our products come with an industry-leading 40-year warranty. So, if you want to replace your existing windows, hurry up to book a free consultation with Magic!

What Other Things Influence a Window’s Lifespan?

Besides the frame material, a window’s lifespan is influenced by:

  • Glazing options. For example, single-pane windows won’t last as long as double- or triple-pane windows.
  • Insulation materials. In this regard, we refer to both the insulating materials added between two glass panes, as well as the weatherstripping and caulking. At Magic, for example, we add the best-performing warm-edge spacers within our Insulated Glass Units. We also add 20%-30% more insulating gas, while the weatherstripping is covered by our 40-year warranty.
  • Installation quality. Even the best, longest-lasting windows on the market won’t perform as intended if they’re not installed correctly. Professional installation ensures that the windows are properly sealed, preventing air leakage and water infiltration. Moreover, improper installation can result in misaligned windows. This can cause operational issues and reduce their overall effectiveness.
  • Climate. As mentioned, a window’s lifespan highly depends on climate. Vinyl, for instance, performs excellently in mild climates. However, extreme weather conditions can significantly shorten its lifespan.

We haven’t forgotten about maintenance, so keep reading to discover some tips on how to make your windows last longer.

How Can I Make My Windows Last Longer?

The question how long do windows last? comes equipped with how can I make my windows last longer, doesn’t it? Consistent upkeep can substantially prolong your windows’ lifespan. This includes regular cleaning, inspecting seals and frames, and addressing issues promptly. These efforts help prevent damage, maintain your home’s energy efficiency, and preserve smooth operation.

As such, here’s how you can make your windows last longer:

  • Clean the windows regularly (the window sash, frame, hardware, and other parts) using solutions that won’t damage the materials.
  • Lubricate window tracks and other hardware parts; if not lubricated regularly, the malfunction of these parts can affect the functionality of the entire window.
  • Inspect the windows regularly to check their functionality, insulation, and operation.
  • Replace old weatherstripping and caulking.
  • Check for drafts and seal any gaps.
  • Follow frame material maintenance requirements. Wooden windows, for example, have to be repainted regularly.
  • Replace broken hardware.
  • Control humidity levels if you have windows that can be damaged by moisture.
  • Address any issues promptly to avoid further damage.

We’ve cleared everything up in terms of window lifespan and maintenance requirements to ensure they do not fail before their warranty ends. But what if you may already need new windows? Can you know for sure it’s time to replace them? Let’s see!

How Do I Know If My Windows Need Replacing?

Knowing when it’s time to replace your windows can save you money and improve the comfort of your home. Here are some signs that may indicate the need for window replacement, including:

  • Visible damage (broken window glass or rotten frames)
  • Drafts
  • Condensation between panes
  • Difficulty in operation

Drafty Windows

Drafty windows may be a sign that it’s time to replace them. Drafts usually indicate poor installation, gaps around the windows, inadequate/old caulking or weatherstripping, broken seals, or warped frames. This can increase your energy bill and cause discomfort. It’s best to address this issue promptly to prevent the windows from causing further damage.

However, drafts around windows don’t always indicate that you need to replace them. It all depends on what causes them. Sometimes all you have to do is replace the caulking/weatherstripping. Other times, the problem can be more serious and may require window replacement.

Condensation Between Glass Panes

If you notice condensation between glass panes, it is a sign of seal failure and reduced insulation. Unfortunately, this is definitely an indicator that you need to replace the windows. Luckily, if they’re still under warranty, you can contact your window manufacturer because the warranty usually covers failed insulating materials.

If you have Magic windows that are still under warranty and notice that their insulation is failing, you should contact us for replacement.

Difficulty in Operation

If your windows get stuck or you’re struggling to open and close them, you may have to assess the hardware. Worn-out hardware, such as locks, hinges, and handles, can affect the functionality of a window, and you’ll eventually need to replace it.

Additionally, warped frames can cause operational issues, indicating that the window’s structural integrity is compromised.

High Energy Bills Without Any Apparent Reasons

Have you noticed that your energy bills have increased even if there are no apparent window issues? There may be hidden problems that affect your house’s energy efficiency.

In this case, it’s recommended to contact an expert who can assess your windows, find the problem, and offer a solution.

Cost Considerations: Repair vs. Replace

Should you repair or replace windows? The answer depends on the extent of the damage and how old your windows are. Repairing is more cost-effective for minor issues, but replacement is preferred for severe damage or old windows. If the window is over 20 years old, you should probably replace it rather than pay for multiple repairs (not Magic windows though; they last 40 years and rarely need repairs!).

Window repair can cost between $100 and $600, depending on what needs to be repaired. In addition, you may have to pay for labor costs, which range from $100 to $300, depending on the expertise of the technician.

Replacing windows can cost between $300 and $2,500+ per window. The final price depends on the window quality, window type, frame materials, glazing options, and other factors.
