How long do windows last?
Windows typically last 15–20 years. Here's what affects their lifespan and the signs it's time to replace them.
Average lifespan
Vinyl and aluminum windows last about 15–20 years; quality wood and fiberglass can last longer with maintenance. Energy-efficient glazing may need replacing sooner.
What affects longevity
Climate, sun exposure, material and installation quality all matter. Proper sealing and maintenance extend life significantly.
Signs it's time to replace
Drafts, condensation between panes, difficulty opening, or rising energy bills are common signs your windows are aging.
