Mold Around Windows
Windows are common condensation surfaces. When indoor humidity is high or window assemblies leak, mold can develop along sills, frames, and surrounding walls.
Condensation
Cold window surfaces collect moisture from warm indoor air. Single-pane windows and inadequate insulation worsen this.
Failed seals
Failed window flashing or caulk can allow rain intrusion that supports mold growth in the surrounding wall.
What to do
Reduce indoor humidity, improve ventilation, and have any suspected leak professionally inspected.
