Why Gunner’s Andersen-certified replacement service is a game-changer

Windows are more than just the eyes of our homes. They play an integral role in our home’s energy-efficiency, curb appeal, and protection from extreme temperatures. As windows age, many homeowners begin to notice condensation, drafts, and even visible damage on the panes. Recognizing these signs is essential as they might indicate that it’s time to replace your windows. This is where understanding the life span of different materials becomes crucial. In this post, we’ll explore the average life span of various residential windows.

Life span of different window materials

The life expectancy of windows largely depends on their material, quality, and maintenance. Here’s a brief rundown:

  • Vinyl windows: With a window frame that offers low maintenance, vinyl windows last around 20-40 years. They are known for their durability and energy-efficiency.
  • Wood windows: These windows last 15-20 years and sometimes even up to 30 years when properly maintained. However, wood windows are constantly exposed to the elements, like extreme heat, making them more susceptible to wear.
  • Aluminum windows: Lasting for about 15-20 years, aluminum windows, though durable, can be less energy-efficient than their vinyl and wood frame counterparts.
  • Fiberglass windows: A modern window material, fiberglass is gaining popularity for its long life span and insulating properties.

While these are general guidelines, it’s essential to regularly inspect your windows for signs of aging. Difficulty opening, broken windows, drafty windows, and deteriorating window seals are several signs that your windows might need to be replaced sooner than later.
