Replacement Windows

Perhaps, the challenging task of replacing your windows is behind you. Or you’re considering hiring a pro to get it over with – in which case Maverick Windows can lend you a hand. You can explore their site at to determine if they’re worth their salt.

If the project is complete, you can shift your focus to ensuring the windows last as long as possible. Your contractor probably informed you the lifespan of the replacement windows is 20 years. Were they right?

Yes. Most sources agree that a well-installed and maintained window can have a life expectancy of between 15 and 30 years or more. However, this holds true only if you factor in other valuable points. Let’s cast some light on these variables to demonstrate why such estimates may hold water.

1. Materials Used

Replacement windows come with different warranties and levels of quality. If you choose a window with an extended warranty, it’ll probably last longer than one without. It also points to the quality of materials the manufacturer used to craft the windows.

For instance, vinyl windows can last a lifetime, but their less durable counterparts may require more frequent replacements. Along the same lines, vinyl windows resist corrosion and warping, making them ideal for areas that frequently experience significant weather changes (an aspect we’ll discuss in a bit). Meanwhile, here’s a sneak peek of the lifespan of various window materials:

  • Fiberglass: 15 – 40 years
  • Double-pane windows: 10 – 20 years
  • Aluminum: 15 – 30 years
  • Steel: 10 – 20 years
  • Vinyl: 15 – 40 years

If you opt for wood windows, invest in a high-grade wood such as Douglas fir or mahogany, which are more durable and less likely to rot. Similarly, the type of glazing used is critical for longevity. The low-E glass keeps your window looking new for far longer than regular glass. The same goes for the type of window you installed – single pane windows may last up to 9 years while double pane windows could last 2-3 times longer (as our list shows).

2. Installation and Maintenance

No matter the window quality, proper installation ensures it lasts. Poorly fitted windows can cause air leaks and condensation problems. For your windows to serve you for many years, hire a competent pro who can guarantee a quality installation. Besides, most professional installers offer warranties as a safeguard against faulty workmanship.

That said, the installation isn’t enough to keep your windows in tip-top shape. Regular maintenance is paramount for optimal performance. In fact, window manufacturers recommend regular cleaning and minor repairs to extend the life of your windows. By checking for signs of wear or damage, you can prevent leaks or other issues that may compromise the structural integrity of your windows.

All the same, your approach to window cleaning can damage your windows in short order. For instance, pressure washing your windows can drive moisture into the seals and compromise their functionality. Hence, follow the manufacturer’s instructions for cleaning your windows to ensure a longer lifespan.

3. Usage

How you use your windows can increase or decrease their lifespan. For instance, opening your windows frequently allows fresh air into your den, but it also contributes to wear and tear as the hinges get used more often. Also, forcefully opening and closing your windows may damage the hinges or frames, leading to premature replacement.

Even so, you can deal with most usage-related damages by replacing the affected part or component. But if the damage is significant, a window replacement would suffice.

This may apply even if all other factors don’t impact your windows. Therefore, keep window usage in mind when determining the duration your windows are likely to last.

4. Exposure to the Elements

Mother Nature can be a harsh mistress. If she unleashes her wrath, your windows’ external parts may suffer. For instance, a sudden hailstorm can damage a wooden window’s finish, exposing it to further damage and thereafter forcing you to replace it. Similarly, precipitation and cold temperatures can cause premature deterioration or damage, while high humidity and corrosive environments can reduce the lifespan of your windows.

Also, exposure to direct sunlight speeds up fading and discoloration, shortening your windows’ life. What’s more, extreme heat may cause the frames to warp. Hence, you may need to replace your windows earlier than anticipated. And while it’s difficult to defy some of the laws of nature, you can install storm windows to reduce the risk of damage.

In short, your area’s climate impacts your replacement windows’ longevity. Hence, it’s advisable to opt for windows with weatherstripping, which helps seal out the elements and protect your home from drafts. Also, your window choice should factor in the temperatures your windows will be exposed to, especially if your area experiences extreme weather conditions.

By and large, the lifespan of your replacement windows hinges on a combination of factors that may conspire against them.  Ensure to factor in the above elements when planning for window replacement to maximize your investment.
