Household mold is not only ugly but also difficult to remove once established. “Mold grows roots called hyphae, so it can be difficult to remove from porous and semi-porous surfaces,” Michael Rubino said. “The small size of spores and mycotoxins also allows them to reach deep within the fibers of the surface, making them difficult to remove.”
To avoid mold problems, then, the ideal solution is to prevent mold from establishing itself in your home in the first place. Much of this, Rubino said, involves common-sense measures for consistently controlling moisture levels in your home, since mold thrives in moist environments and mold colonies can establish themselves in as little as 24 hours. Among his recommendations are fixing leaks as soon as possible, maintaining indoor humidity levels at between 35 and 50%, having flood controls installed and a drainage plan in place if you have a basement, and maintaining airflow in bathrooms by running an exhaust fan or keeping a door or window open.
