Drafty Windows: Causes and Fixes for Virginia Homes

Why Drafts Show Up Around Windows

A window that feels cold or leaks air does not always mean the pane is the problem. Homeowners often notice it as a room that is harder to heat or cool, especially near older windows.

• The sash does not lock tightly or sits unevenly in the frame.
• Moisture is trapped between the panes, not just on the interior surface.
• You see cracked caulk, brittle weatherstripping, or visible daylight around the frame.
