Why Replace Your Windows?

Many homeowners put off window replacement until issues become hard to ignore. But the truth is, windows that are more than 15–20 years old often cause hidden problems. Signs you may need new windows include:

  • Drafts that make certain rooms uncomfortable.
  • High heating or cooling bills.
  • Condensation between panes of glass.
  • Difficulty opening, closing, or locking windows.
  • Peeling paint, rotted frames, or cracked glass.

Upgrading your windows provides several long-term benefits. Not only do new windows help you save money on energy bills, but they also improve your home’s security, increase resale value, and instantly refresh curb appeal.
