Where there is dampness and excess moisture usually there are some common signs of mold such as musty odors, visual mold seen on the surfaces of substrates such as drywall, wood framing, ceiling joist and beams. Removing mold is one part of the process, but controlling the moisture and dampness is critical. Repairing any source of the moisture problem that caused mold to grow such as water leaks and flooding. If the areas such as floors, carpets, wallboard etc. are not properly dried out then mold will begin to grow after a 24 hour period depending on the moisture level.
Excess relative humidity over 60% causes mold to grow sporadically. It's like putting 'gas on the fire,' where mold spores thrive in high humidity and warmer temperatures. I see this often in the hot and humid months of Cape Cod, Massachusetts and the islands of Nantucket & Martha's Vineyard. When vacationers come to open up their summer homes surface mold is seen throughout several rooms where the humidity has not been controlled. Odors persist in crawlspace and basement due to lack of dehumidifiers which should operate 24/7 when necessary. Dehumidifiers are best between 30% & 50% R.H. according to the EPA
Dampness affects many people with asthma. When dampness and high relative humidity are controlled then breathing is much more comfortable. Remember, a mold inspection is more than just testing, a thorough visual inspection with the right instruments helps when it comes to finding moisture and any form of water intrusion. Even after mold removal is conducted if needed, your home still needs to control the moisture. If preventative measures are not taken then the mold can and more than likely will reoccur. It's like bringing your vehicle in for a repair, if we do not change the oil often, then another problem will occur. A costly one at that.
