Mold became a big buzzword in the housing industry at the beginning of the 2000s. Health issues attributed to mold were the subject of lawsuits and mold disclosure documents became a standard part of real estate contracts. Yet mold caused by damp conditions in a home is nothing new. Most old homes are not as airtight as modern homes are, so they can “breathe” better and allow moisture to escape. Damp conditions in a modern home need to be monitored, but it also helps to be aware of the signs.
Damp Patches - Dark or yellowish stains are a sign of exterior leaks. Exterior leaks allow water to infiltrate the walls, where the moisture and darkness contribute to the growth of mold. Even a small stain can be indicative of a much larger problem. Many times, the remedy is as simple as repairing or replacing damaged roof flashing and gutters or removing leaves and debris from the roof and gutters.
