NONSPECIALIZED “MOLD REMOVAL” FIRMS
If the proposed contractor for cleaning up your water damage or mold problem is a carpet cleaner or a plumber, have them leave now! You are going to need a real professional. Many plumbers and carpet cleaners try and dry out properties and complete mold removal at your expense and their gain. Not only do these companies occasionally cut corners, they sometimes charge much more than the industry standard.
Beware of Preferred Mold Vendor Programs.
