Factors That Determine the Lifespan of Windows

Types of Windows

There are different types of window materials, and the type you choose can impact the lifespan of your window. Below are the most common materials and their expected lifespan:

  • Vinyl Windows

Vinyl Windows are the most affordable window option. They can last between 20 and 40 years. However, if your vinyl window is frequently exposed to direct sunlight, its lifespan may be reduced.

Fiberglass greatly reduces your energy bills. They’re, however, expensive. Your fiberglass window can last up to 20-40 years. You can also get a limited lifetime warranty on it.

  • Aluminum window

These materials can last you for about 20 to 30 years. They also don’t require high maintenance. However, you can decide to repaint it at any time.

  • Wood windows

A wooden window can last for over 30 years. You can get a warranty of about 20 years on the non-glass parts of the window. Repainting it every two years will also make it last longer.

Mother Nature

Mother nature is simply inevitable. Although bad weather can happen rarely, when it does, it can greatly reduce your window’s lifespan. The following are weather conditions that can affect your window:

  • Sunlight: Irrespective of the type of window, consistent exposure to direct sunlight can reduce the quality of your window.
  • Humidity: Water damage can reduce the quality of your window and make it break down quickly. It can lead to mold infestation, cracked paint, discoloration, and warping
  • Extreme temperature changes: Your windows can change shape and warp due to a sharp temperature shift.


Just like every other home property, your windows need to be cared for. This way you can enjoy them for a long period. The type of window material you use will determine how you maintain it. Some materials require high maintenance, while some don’t. Therefore consider the type of material and act accordingly.

Installation Quality

Although window installation may seem easy, it requires experience and expertise. Therefore, your window’s lifespan depends on the installation process. To enjoy your windows for a longer period, it’s best to consult professionals who have been in the game for a long time. They take note of every detail and ensure you get the best.

When Should You Replace Your Windows?

When They’re Drafty

Drafts are not minor problems. They make your HVAC system do extra work to maintain the room’s temperature. They also make you spend extra on energy bills. If your windows are drafty, they will let in hot air, and your home may become uncomfortable and more humid. To confirm a drafty window, close and lock the window and put your hand at the top or bottom of the window sash. If you can feel the air, then there’s a high chance the window is drafty and should be replaced.

There’s an Obvious Damage

Having cracks in your window is not physically appealing. A little crack in your window can eventually break down completely. This will make your home porous and liable to pests, mold, and water seepage. To ensure your safety, it’s better to replace a damaged or cracked window immediately.

Your Windows Don’t Dampen Sound

Windows are meant to protect you from every external element, including noise. If you live in a busy environment, you can choose double or triple-pane windows. They help to prevent outside noise from penetrating inside. However, if you notice your windows don’t dampen sounds anymore, then it’s time to replace them.

Having your windows in good condition will make you enjoy the comfort of your home for a long period. While windows are meant to last for as long as 30 years and above, you must watch out for factors that can shorten their lifespan and waste your money.
