Here we explain how an inadequate mold cleanup plan can end up costing unnecessarily when hiring a mold cleaning company. This section of our "How to Clean Mold" article describes common mistakes people make when attempting to clean up mold. Avoiding these mold cleanup errors can save you money and may also avoid dangerous side effects of bleach, mold chemicals, or ozone when improperly applied. We also discuss common errors made when cleaning wood surfaces, such as relying on bleach or performing expensive and unnecessary cleaning on cosmetic black mold on wood surfaces. © Copyright 2009 Daniel Friedman, All Rights Reserved.

MOLD CLEANING MISTAKES people make when cleaning-up moldy building materials and moldy surfaces, continued. IMPROPER MOLD CLEANUP JOB DEFINITION - inadequate mold inspection, testing, remediation planMold tests with no inspection: The most common complaint we hear from readers is that they have just paid a "mold expert" (read "weekend mold class") to "inspect and test" their building for toxic mold, but the expert, who may have been paid $600. to $2400. did not do a thorough job. Tests for mold, used without an accompanying building inspection by an expert, are not reliable when they give a negative ("no mold found") result.
Our photo at left shows a very moldy pantry in a home. Even if this is all the mold that was seen, mold growth this heavy suggests damp indoor conditions - it may be appropriate to inspect the building carefully and completely. If you are betting the health of building occupants and perhaps also many thousands of dollars on the results of a "mold test" then shouldn't the test be thorough and valid? In our opinion, we'd rather have no tests performed than accept the "findings" of unreliable tests and screens for mold.
A common example is the discovery of asbestos pipe or surface insulation in a building which because of its location or condition needs to be encapsulated or removed. Since the technology for mold remediation involves similar containment and cleaning standards, if you have an asbestos problem at a different area on a moldy building you should discuss adding that work to the job. If asbestos materials are in the mold-remediation area and will be disturbed by the mold cleanup process, removing and cleaning this material will probably be unavoidable and will, unfortunately, add to the cost of the job. INCOMPLETE MOLD CLEANUP or incomplete removal of moldy materials, or RELYING ON of BIOCIDES, MOLD SPRAYS and MOLD ENCAPSULANT PAINTS
Spraying biocides or fungicidal sealants over moldy dust, dirt and debris that should have been removed (photo above right) is a common mold cleanup error. You may be leaving "dead" but toxic or allergenic particles at high levels in the building. We like biocides as a final wash, and we like fungicidal sealants in problem areas because by reducing the moisture-uptake of wood surfaces they probably retard future mold growth. Our photo (above left) shows a worker applying biocide to carpeting - not a procedure that we recommend. Moldy wall to wall carpets should be removed. But biocides, fungicidal sprays, and encapsulating mold paints are not an effective substitute for removing the problem mold reservoir in a building. See FUNGICIDAL SPRAY & SEALANT USE GUIDE for additional details. See MOLD SPRAYS, SEALANTS, PAINTS for a discussion of when where how and why to use biocide or fungicidal sprays and encapsulating mold sprays and paints.
Even with these steps, unless the property manager takes the necessary steps to prevent future water in the crawl space this area could have a new problem, especially if it is re-insulated using fiberglass batts. ... Technical Reviewers & References
