So When Is It Time to Replace Your Windows?

If you’ve noticed any of the following signs, it may be time to consider a window replacement:

• Drafts or uneven temperatures near your windows

• Condensation or fog forming between panes

• Difficulty opening or closing

• Visible wear, warping, or rot around frames

• Higher-than-usual heating or cooling bills

Small issues can quickly lead to larger problems. Replacing your windows early can improve comfort, reduce energy costs and protect your home’s structure for years to come.
