Black mold growing in the attic does not necessarily cause your house air contamination. However, mold usually becomes an issue when discovered during the home inspection. In addition, depending on the attic mold contamination extent, correcting the problem could make a significant hole in your budget.
There are actually several different reasons that might be responsible for the mold to appear under the house roof… and sometimes compromise your real estate transaction. That is why attic evaluation and attic mold treatment (if you’re out of luck) should be performed before even putting your house on the market, and on regular basis.
