Mold Removal and Mold Remediation Advice

Q. I came across your website this morning, very interesting. We are currently undergoing a mold remediation issue with our insurance company and their testers and sub-contractor. Here's a brief history. We had a leaking water pipe in the upstairs bath for most of a week, while we were away. The leak flooded the master bath and bedroom, the other bath, brought down the ceiling in the kitchen, and flooded the (unfinished ) basement. The water removal company brought in fans and dehumidifiers and got rid of most of the water and dampness in about two weeks. A mold testing company came in and found a few "trace" spores of Stachybotrys, plus trace spores of Nigrospora, Penicillium and Aspergillus in their Tape Life samples. Because of this, the insurance company brought in a mold remediation company, which completely took out all the wetted drywall, carpets, hardwood flooring, and, removed everything from the house for subsequent cleaning. They sanded down and treated all locations found to have visible mold (mostly some plywood floorboards, some studs and joists). I then had them paint over these areas with a mold-fungicide paint. Meanwhile, the mold testing contractor came back in and collected Air Trap sample from inside and outside the house. The outside samples found total counts of >55,000 (various species and types), and the inside house samples found 6,000 - 10,000 counts (of the same types). They claimed that the remediation was successful based on this and ordered that reconstruction should begin. We then hired a private environmental firm to come in and perform their own sampling (a second opinion). This company has come twice and performed the four-plate agar culturing protocol from their air sampling device (Andersen sampler). This second opinion found about the same both times (both after the "remediation' was finished), of approximately 7,000 mold counts, consisting of Penicillium, Paecilomyces, Aspergillus, etc., in two locations in the house. The counts of 7,000 or so from our second opinions and similar in numbers and relatively similar to the types found by the insurance people in their air sampling (6,000 - 10,000). No Stachybotrys spores were found by either company, since the initial tape life samples of about 3 months ago. We have been living in a hotel for over 3 months now as this work has progressed. My question is, are the above types and numbers of mold spores found (by both companies), after the remediation work had been completed, common to inside house air quality? Should we be concerned about counts of 6,000 - 10,000 spores and structures inside the house? [Nov. 25, 2002]

A. First, read the 25 steps for safe and effective mold removal. The best mold remediation procedure for water damaged and mold damaged wood is to replace it with new mold-free timbers and other building materials, not to just to sand it. Often, sanding is ineffective at getting out mold spores that grown beneath the wood surface. Better than sanding is to use a power planer to cut off one thin veneer layer of wood after another until there is no visual evidence of mold contamination. Once there is no visual contamination, physical wood samples need to be cut out of a representative number of wood timbers and plywood sections so that these samples can be inserted into the malt agar extract contained in mold culture plates, and have the mold analysis laboratory observe these samples for 7 days to see if there is any significant mold growth from the physical wood samples. Second, the levels of mold AFTER your mold remediation may still be unhealthy to your family. Remember that the major problem of living inside a mold contaminated home is the continual exposure to mold and the buildup of mold spores inside a home over a period of time.  If outside your home, there are 50 rats resident just outside of your home structure, but only 7 rats are living INSIDE your home, would you conclude that the number of rats inside your home was too small in number to be a health threat to your family?  Third, be sure that an extremely strong and effective fungicide explained in the special report Mold Home Remedy Recipes has been used repeatedly during the mold remediation process.
