Why Upgrade Your Windows and Doors?
Older windows and doors can cost you more than you think — especially in Michigan’s climate. Drafts, warped seals, or thin glass all add up to higher utility bills.
Common signs it’s time to replace:
Cold spots or visible drafts
Foggy glass or condensation
Hard-to-open windows or sticking doors
Outdated styles or peeling trim
Noise from outside or reduced insulation
Upgrading improves energy performance, resale value, security, and daily comfort.
