When to Replace vs. Repair Windows in Bethesda, MD

What The Window Is Telling You

Situations Where A Repair Is Usually The Better Call

A repair usually makes more sense when the failure is limited and the window is otherwise structurally sound. Common repairable problems include worn balances, failed latches, brittle weatherstripping, minor sill rot, and failing exterior sealant.
