Drafty Windows in Older Mandeville Homes: Common Problems and Solutions

A drafty window is more than a comfort issue in Mandeville, especially in homes that have seen years of Gulf Coast heat, humidity, and seasonal storms. It can make a room feel unevenly cooled, let humid air creep in, and force the HVAC system to work harder than necessary.
