Window and Door Replacement Planning for South Carolina Summers

Either way, persistent moisture around the glass is not just cosmetic. It can shorten the life of surrounding materials if it is ignored.

Exterior doors often fail in small ways first. The threshold may no longer meet cleanly, the sweep may leave a gap, or the weatherstripping may be flattened from years of use. That is enough to let heat and moisture into the house day after day.
