How to Fix Drafty Windows in Old Bethesda Homes

Why Old Windows Start Letting Air In

In older Bethesda houses, window drafts usually show up after years of seasonal movement, worn parts, and seal failure.

That is why a real inspection matters more than guessing from inside the room.

Repairs That Actually Help, And When They Do Not
