How Long Do Windows Last? Lifespans of 5 Popular Window Types

Windows can last between 10 and 80 years.

This is because a window’s lifespan is entirely dependent upon the material, climate, installation technique, usage, thermal efficiency, and maintenance routine.

But windows can last anywhere within that range, and the lifespan of windows will vary greatly if you have old windows or inefficient windows that haven’t been properly cared for.

In this article, you will learn about how long do windows last depending on what type of window, signs of damage, as well as, your cues to consider window repair or replacement. You’ll also know when it’s time to replace your home’s windows and what steps to take next.

How many years do windows last?

How long do windows last? About 10-80 years. In addition to the material, the following factors significantly affect the lifespan of your windows:

• Climate — Extreme heat or cold, frequent changes between the two, hurricanes, hailstorms, snow, rain, salt, and sun exposure all contribute to wear and tear on the windows in your home depending on the region you live in. These conditions affect how long your windows typically last and can mean you may need to replace your windows sooner.
• Usage — The more you use them, the faster they wear out from the daily function. After years and years of opening and closing, it’s more likely that parts may break or warp, and eventually, the window will need to be replaced. This applies if have single-pane windows or older windows that were not built to modern standards.
• Installation technique — Windows are designed to last for years, but installing them incorrectly can cause drafts, broken seals, humidity issues, and overall poor performance. Improper installation dramatically shortens the life of your windows and increases the likelihood that windows need to be replaced sooner rather than later. 
• Thermal efficiency: A window’s U-value is a measure of its thermal efficiency. The higher a U-value is, the more heat the window will lose during cold times of the year. This heat loss increases energy bills and the build-up of condensation. Over time, an increase in condensation will lead to the need for a window replacement. Energy-efficient windows last longer, reduce heating and cooling costs, and are environmentally friendly. Also, modern double-pane windows or double or triple-pane windows with low-E coatings help keep your home more comfortable and can last for decades if maintained well.
• Maintenance — Following the proper maintenance protocol (like cleaning your windows regularly) for the type of window you have is essential to extending its lifespan. Each will have its own unique needs based on the material it’s made from. Skipping upkeep will cut years off the lifespan of your windows. Overlooking routine maintenance means it may be time to replace them sooner than expected.

Vinyl Window Lifespan

How long should vinyl windows last? Well, it depends. If you consistently maintain your windows, it will last.

Regular vinyl windows have a lifespan of about 10-20 years. Premium vinyl windows range more in the realm of 30 to 40 years. With proper care, vinyl window frames can last for decades before you need to replace them.

Sunlight will break down the vinyl material and degrade the efficacy of your windows at a faster rate. Living in an area that fluctuates between extreme heat and cold during the year will also reduce their lifespan.

Wood Window Lifespan

Wooden home windows last decades, anywhere from 30 to 60 years

The key determining factor of how long your windows last is the level of maintenance you put into them. Windows may deteriorate if you neglect regular cleaning, sealing, and minor repairs, which can make your home less comfortable over time. 

It’s important that you clean and inspect wood frame windows once every six months for cracking, moisture, weatherstripping damage, peeling finish or paint, and loose caulking. 

Knowing when to replace or repair your wood windows can also help you avoid higher energy bills, drafts, and potential damage to your home.

Double-Pane Window Lifespan

Double-pane windows typically last 10–20 years, but on average, they hold up for around 10 to 20 years. Climates that bounce back and forth between heat and cold reduce life expectancy.

A frequent change in temperature causes the air between the panes to expand and contract. This movement breaks down the seal letting moisture get between the glass and fog up your windows.

This moisture creates fog and makes it difficult to see out of the glass. The only way to correct this is by replacing the glass pane or the window in its entirety.

Fiberglass Window Lifespan

Fiberglass windows can last a long time, delivering a whopping 50-80 years on average to homeowners. There are also modern windows with low-emissivity coatings, helping with energy efficiency.

Fiberglass is the most durable against the elements impervious to moisture, warping, and cracking. It also needs minimal upkeep, meaning you spend less time worrying about how long your windows last and more time enjoying the comfort they provide. 

When choosing replacement windows, fiberglass is a prime option because it can help with long-term energy savings and overall home protection.

Aluminum Window Lifespan

Anywhere from 20 to 40 years.

Weather can damage aluminum. So if hurricanes and hailstorms frequent your home, your windows are going to have a shorter lifespan.

Aluminum is not the best when it comes to insulating your home. So it might make your home warmer in summer or cooler in winter, which can increase energy bills. 

Over time, prolonged exposure to moisture can also lead to rust, further compromising the frames. If you notice signs that your windows need replacing, such as corrosion or drafts, it could be time to replace windows with a more energy-efficient material.

Signs That It’s Time To Replace Your Windows

No matter the material, there are signs it’s time to replace your windows. Factors like high energy bills, drafts, loud outdoor noise, foggy glass, visible damage, or difficulty operating all point to knowing when to replace. 

When should windows be replaced? Look for these specific indicators by material.
