This customer had a leak coming through their window. Over time the moisture seeped into the walls and caused mold. The reason is that a leaky window will ultimately cause mold. Moisture or dampness is the perfect condition for mold to grow. When you look at leaky windows and frames, you are most likely to see black spots, discoloration, and fuzzy growths, being wet or moist. SERVPRO of Gillette does not do window work but they were able to mitigate the mold beneath the window. This consisted of removing the damaged dray wall, then drying out the framing and applying an antimicrobial to the surrounding surfaces.
