When to Replace vs. Repair Windows in Bethesda, MD

Start With The Symptom, Not The Sales Pitch

A bad window rarely fails in only one way, and the pattern of wear matters more than the age alone. A stubborn sash, a loose latch, or air slipping in at the frame often points to a repairable issue rather than a full replacement.
