Toxic molds become a problem when spore levels are significantly higher inside than outdoors.
Mold growth happens because water is inside the building or on contents. It may be from a roof or window leak, a plumbing problem, weather, fire or lifestyle issues. There are many reasons why water may be inside your building.
Without knowing the source or sources of the water, no removal will permanently fix the mold.
There are millions of different kinds of fungi; only a very few produce toxins. These toxins are mycotoxins. Mycotoxins are produced some of the time, under some conditions, but, so far, are challenging to reproduce in a lab setting. All toxic molds have the potential to cause health effects. The and severity and kind of symptoms depend, in part, on the types of fungi present, the extent of an individual’s exposure, the ages of the people, and their existing sensitivities or allergies. The medical consensus shows links to respiratory health problems. Though everyone responds differently, elevated levels of mold should always be corrected.
The moisture is damaging the building. Control is the key. Where there is moisture, there is the potential for mold growth.
Toxic mold spores, similar to seeds in plants, are spread by wind or drafts. When a spore lands on a damp surface that is the right temperature with water and cellulose for food, mold usually grows. Leaks or damp indoor air are both factors in indoor toxic mold growth.
So, accuracy before momentum on removing mold: Know ALL the sources where water if getting into the building. You should be aware if humidity becomes trapped inside the building. Verify that all the water leaks are repaired, and there are sufficient air exchanges inside the building. Then, after testing to be sure all the mold spores are gone, rebuild. Don’t rebuild before you test.
If the moisture continues, the mold problems may come back.

If you have a leak, start professional drying as soon as possible. This drying can significantly reduce mold growth.
