That's how it starts. Folks have been convinced it's something one does when they buy a house. Realtors don't know anything, and in their never ending effort to appear knowledgeable, recommend it because their home office tells them to recommend it because their insurance agent tells them to recommend it because their legal counsel tells them to recommend it and they don't know why. I'll tell you why. It's because of some completely stupid lawsuit in Texas that convinced everyone that they might be held liable for hundreds of thousands of dollars if they don't disclose mold. We all got to read about it. What we didn't get to read about is the judgment was overturned on appeal, the judge indicated in his opinion the original jurors were morons and that the decision was baseless, and the whole thing was reduced to lawyers fees. If there's one thing I know for sure, it's you test for mold, you find mold, and the tester has a wall of numbers indicating it's a grave threat. It's bullshit. If you want to be a certified mold tester, it costs about $185 and you sit through a 3 hour Power Point presentation, take a test designed for mouth breathers, and they give you a little badge and certificate to hang on the wall, and now you can act like you know something. From everything you've told us, I'd say screw the moron mold guys. You had a water issue. Mold grew because of it. Do what Kibbel said and make sure there's no lingering moisture issue. If not, stop worrying about it.
