How long? According to a 2007 study from the National Association of Home Builders, aluminum windows last 15-20 years, wooden windows about 30, and fiberglass and vinyl even longer. To figure out if they’re reaching the end of their life cycle look to see if they:
- Accumulate condensation between panes
- Feel drafty, due to bending, bowing or sagging
- Leak during a rainstorm
- Are cracked, faded, or worn-looking
Windows are among the least energy-efficient surfaces on your house, and if you have single-paned windows, it’s no contest on the question of replacing them. The U.S. Department of Energy estimates energy loss through windows may make up 10-25 percent of your energy bill.
Sometimes your reasons are a combination of practical and cosmetic. Perhaps most other homes in your neighborhood have upgraded, or already featured high-quality windows and door. With an eye on re-sale value you are upgrading to add curb appeal. Prospective buyers greeted at a front door and windows as beautiful and practical as they can be, will assume the rest of the house is the same.
Replacing windows with the most energy-efficient models in an average-size home can run up to $10,000-12,000, with about a 60% return when it comes to increasing the home’s resale value.
By the same token, not all decisions we make are financial. A new lease on life may have put you in the position to spruce up your house with a beautiful new door or windows. Your guests will receive a warm welcome each time they arrive at your home, and you will enjoy the feeling of renewed possibilities!
