How Long Do Vinyl Windows Last?

5 min read

When it comes to choosing windows for your home, vinyl windows are a popular and practical option. Homeowners often ask, “How long do vinyl windows last?” In this guide, we’ll answer this question, explore the lifespan of vinyl windows, and compare them with other materials to help you make an informed decision.

What are Vinyl Windows?

Vinyl windows have a frame made of vinyl instead of other materials like wood, metal, or fiberglass. Vinyl frames are actually made of PVC, the same material used to make PVC pipes. It’s extremely durable, making it perfect for framing windows.


How Long Do Vinyl Windows Last?

On average, vinyl windows last between 20-40 years. Their life expectancy depends on the climate and conditions you live in. For instance, if your windows are exposed to harsh sunlight for extended periods of time, the vinyl will break down faster and their lifespan will be closer to 20 years. Windows that are in a shady area will have a longer lifespan. 

Their lifespan depends on factors such as climate, exposure to sunlight, and maintenance. For example:

Benefits of Vinyl Windows

As we mentioned, one of the biggest benefits of choosing vinyl windows is their durability. But there are a lot more reasons to choose vinyl:

How Vinyl Windows Stack Up to Other Materials

Vinyl vs Wood

While wood is an effective insulator, wooden windows have a lifespan of 15-20 years, much shorter than vinyl. This is because wood windows are subject to rot, something you don’t have to worry about with any other window material. If longevity and durability are important to you, wood probably isn’t the best option.

If you want the look of wood without the headache, Window World offers interior vinyl windows in colors that mimic light and dark oak. Same beautiful look, none of the maintenance!

Vinyl vs Metal

Metal window frames are typically constructed from aluminum. It’s very lightweight and is typically much cheaper than other materials. Unfortunately, aluminum is a poor insulator and is easily damaged, especially during storms. For these reasons, we don’t recommend aluminum windows since they will likely need replacements faster.

Vinyl vs Fiberglass

Fiberglass windows are often compared to vinyl because of their durability. Even though it is a similar material, fiberglass windows will cost more upfront than vinyl windows. In addition, they’re not as widely available as vinyl and can be harder to install depending on your home.
