Is It Time to Upgrade Your Old Windows?

A window has a lifespan of 15-30 years. Beyond the 20-year mark, windows start to weaken or fail, affecting the comfort and energy-efficiency of your home.

Old, single-pane windows were once the standard in homes. But they lack the insulation needed to prevent damage from condensation on glass. When corroding seals on older windows break down, windows invite drafts inside and let the temperature-controlled air in your home escape, reducing your home’s warmth in the winter and cool comfort in the summer. It also makes your HVAC work harder and results in high energy bills.
