Below is some information that you may want to look through to learn more about mold, where you may find it, as well as how we can eliminate it.
Molds are simple, plant life organisms that do not contain true roots, stems, or leaves like most plants. Mold reproduces by making spores that usually cannot be seen without magnification. Mold spores walf through the indoor and outdoor air continually. When the molds spore lands on a damp spot indoors, it will begin growing, extending a long sprout. This sprout will extend and branch, making a mat- like structure (called a colony) that continues to enlarge until it runs out of food, water or space.
Mold needs 3 things to survive: moisture, food source and room. Food sources can be wood, carpet, drywall, insulation or furniture. Moisture can be direct water, humidity or condensation.Mold can’t grow on concrete or block or metal but can grow on the dirt and debris that accumulates on these surfaces.Mold can be a variety of colors: black, yellow, pink, red, orange, purple or brown. This depends on the food source.
The most common color is white. it is called Aspergillus/Penicillium. It’s a humidity driven mold. This type is very common in the attic and crawl space due to poor circulation.
Once mold is killed it can’t come back to life, it is dead forever.
If moisture is introduced, new mold can begin to grow.
Mold can be in 3 states, alive and growing, dormant or dead.
If the moisture stops, the mold will still be there but it will be dormant as in a coma.
Mold contains thousands of mold spores. If agitated these spores will become airborne trying to find another ideal spot to grow.
If a house is closed up for an extended period of time, condensation can form causing the possibility of mold growth.
If you find what you think is mold, don’t rub it with a rag or sponge, you will agitate the spores causing them to become airborne.
If the mold is confined to a small area, the best way to treat the contamination is to spray the area with straight bleach. This will kill the mold and remove the discoloration.
Crawl Space: probably the most important thing that needs to be in a crawl is a vapor barrier. This is heavy plastic that is laid on the floor of the crawl. This keeps the moisture that comes up from the ground affecting the floor joists and subfloor with condensation causing mold. Also the vents must be clear of any debris to allow for proper circulation.
Attic: proper circulation is critical in an attic to eliminate condensation. Some builders vent the dryer into the attic rather than through the roof. This always causes condensation and mold. Soffit vents are sometime clogged and dirty. If so it is best to replace the vents.
It is a great idea to always have a dehumidifier running in a basement. With our high humidity summer days and high water table they really help. Don’t place the dehumidifier close to the floor drain as that will cause the moisture to be recirculated back into the dehumidifier.
