Drafty Windows: Common Causes and Fixes for Virginia Homes

How A Window Becomes A Source Of Cold Air

A drafty window is not always a sign that the whole unit has failed. In Virginia homes, especially older places with mixed weather exposure, the issue often comes from worn seals, gaps around the frame, or hardware that no longer pulls the sash tight.
