Home windows typically last about 15 to 20 years, and after that period the seals may begin to weaken and allow water or drafts to seep in. It may be time to replace your windows if they are hard to open, damaged or not well insulated, which could contribute to higher energy bills.
Home windows have a lifespan of 15-20 years. Once they reach this age, the seals start to weaken or fail, which leaves you open to drafts and water seepage. In addition, single-pane windows were the standard 15+ years ago. These windows lack insulation and are not as energy efficient as modern double-pane windows.
How Often Should Windows be Replaced? The average lifespan of windows is between 15 and 30 years. Depending on the craftsmanship of the original installer, the materials used, and the weather conditions where you live, the functional life of your windows can vary between ten and fifteen years.
While old windows might still be functional, there's a good chance they're not very efficient. Windows that are over 20 years old should be replaced. If you've lived in your home for decades and have never replaced the windows, they are likely original to the house.
Fiberglass vs Vinyl Windows
Fiberglass is another long-lasting option for windows, but there are definitely some pros and cons. Fiberglass windows can last up to 50 years, which is amazing. But as you'd expect, they are a much greater upfront investment than vinyl windows.
Old windows can last another 100 years if properly maintained. “They may be 100 years old, but if kept in good shape they can last another 100 years, and I don't think you'll find a replacement window that can last 100 years,” says Beatty Mel. Window restoration is better for the environment.
As already mentioned, the longest-lasting window frame material is fiberglass. This is because wood can deteriorate and warp over time and vinyl will eventually corrode, crack, and warp. Fiberglass is as durable as they come, resisting warping, cracking, and rusting.
Is it cheaper to replace all windows at once? Generally yes, the cost per window will likely be lower if you choose to purchase your windows in bulk and replace them all at the same time. Doing so will usually save on labor costs for installation as well.
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.
You will still be able to use windows 10 after October 2025, it is just that it will get less secure as time goes by.
Materials Matter. If your windows were built before about 1960 then they are likely made of old-growth wood which is far superior to today's woods. Old-growth wood is more rot-resistant, insect resistant, and more dimensionally stable that anything at the lumberyard today. There's really no comparison.
Outdated operating systems have no security updates, fixes, or patches. Any business still using this technology risks becoming a susceptible target for computer viruses and malware. Cybercriminals are also known to target users of outdated Windows operating systems and Office applications.
The average lifespan of residential windows is 15 to 30 years. Well-maintained products may last beyond the 20-year mark, but once your windows start approaching two decades old, it's time to think about replacing them.
According to the Remodeling's 2023 Cost vs. Value report, replacing vinyl windows adds an average of $13,766 in value to a home — about 69% of the cost of the project. The return on investment for replacing wood windows is slightly less, adding $14,912 in value to your home, on average.
If you live in an area with extreme weather conditions, it's best to wait until the spring or fall to avoid any damage that could be caused by installing replacement windows during extreme heat or cold. If you're working within a tight budget, waiting until the end of the year may be your best bet.
Disadvantages of vinyl windows:
They have the tendency to sag due to their flexibility. Their flexibility also limits their size and the weight of the glass they frame. Many people find them less elegant or natural-looking than wood.
Vinyl Windows are Different than Other Options
In extreme weather conditions, the possibility of discoloration exists. Since these windows can't be repainted, the entire window must be replaced. Also, real estate experts say vinyl window replacements don't add as much value to a home as other options.
Vinyl windows, on the other hand, do not absorb water and are not prone to rotting. These windows, when installed properly, can go for long periods of time without maintenance. So in general, the answer is that vinyl windows will last longer than wood windows.
The type of window that is being installed is another thing to consider. Some windows, like casement windows, are simpler to install from the outside since they open outwards. Other windows that open inwards, like double-hung windows, are simpler to install from the inside.
The window's material has a major impact on price. Each type of material varies in durability, required maintenance, and customization options. Aluminum and vinyl frames are the most cost-effective, while wood windows are the most customizable.
Windows 10 version 22H2 is the current and final version of the operating system, though Microsoft said it will continue to release monthly security updates for all Windows 10 editions until it reaches end of support on Oct. 14, 2025.
Renewal by Andersen windows can last for 40 years or longer. Its patented Fibrex material is twice as durable as vinyl, which lasts 20 to 40 years on average. However, extreme climate, weather conditions, and other outdoor influences can drastically shorten your windows' lifespan.
