Drafty Windows: Causes and Fixes for Montgomery County Homes

Where Window Drafts Usually Begin

When a window starts leaking air, the cause is often simpler than homeowners expect.

• Match the weatherstripping to the sash design instead of forcing an oversized strip into place.
• A failed bead of caulk can look minor but still let in a surprising amount of air.
• Adjust or repair hardware so the sash closes tightly.
• Seal gaps around the interior trim only after checking the exterior first.
• Repair flashing or surrounding trim if water intrusion has damaged the opening.
