Mold Culprit: Air Gaps From Windowsills, Cables, and Wall Outlets
Leaky building insulation allows the summer sun warmed exterior walls to push heat through the building cavity and into the finished interior wherever there is an air gap. This can be found around windowsills, cables, and electrical outlets. Once the warm air escapes into the finished area and hits the air-conditioned environment, condensation occurs. The damp surface creates a perfect environment for MOLD to colonize.
