According to Dr. Rapp, first and foremost you want to get away from the problematic area—which means move if you have to.
"I've seen people try to stay in a moldy house when their child is very sick or they are very sick. They try to clean the place up. They take out the moldy carpet and decide to paint the moldy walls. But they can become so desperately ill that it is very hard to treat them in the future."
- Professional remediation. If your mold problem is sizeable, or if you have black mold, you may want to consider hiring a professional remediator. Unless proper precautions are taken, undertaking black mold removal on your own can be almost as hazardous as doing nothing at all,19 because spores will be stirred up and sent airborne during the cleaning process.
This may not be cheap, but it's better than the alternative. If you catch the problem early, you can save yourself tens of thousands of dollars in extra cleanup costs. (Trust me, as I made this mistake myself and wouldn't want to see anyone else go through it.) Make sure a remediator doesn't use chemicals you're sensitive to—a chemical allergy is the LAST thing you need while you are recovering from a mold poisoning!
