New Construction – 4 Three Story Condo Units – Franklin, TN
Builder has a mold condition in the basement on the firewalls between units. Purple fabric covered drywall was suppose to be mold resistant. Builder had tried a mold killer chemical and was not successful.These units were still under construction and not completely dried in, there were no mechanicals and still on temporary power. The full basements are below grade and allowed the rain to collect, during the construction process and with no power the sump pumps were not operable to eliminate the water. This has allowed the moisture, as well as the mold, to wick up these fire walls. There is also visible manifestation on the first floor fire wall. After a thorough inspection there are several areas of concern.
All active growing molds were treated with an oxidizing solution, which burns the mold and kills it and bubbles it out of the pores it has grown into. When this process occurs the mold spores very rapidly trying to reproduce as fast as it can and it appears to be smoking. The total cubic feet of air is also cleaned during the entire spraying process and continued until final test results are received from the lab. The air sanitization equipment used creates hydroxyls, which oxidizes all living airborne contaminants such as mold spores, germs, bacteria, viruses etc. The ionization of the air sanitizers utilizes the moisture in the air to clump all the fine contaminants together to make them heavier than air and drops to the floor.
Each unit was cleaned and cleared by the lab and flipped back to the builder in 15 days. This was a huge job since there was no HVAC for air circulation, so 12 20" box fans were used per unit. It is close to impossible to clean stagnant air so keeping all the fans running plus the air sanitizers and air scrubbers just using temporary power was hard until the builder added a second temporary electric box to handle the load.
Lab reports indicate no elevated or toxic molds exist upon completion. of each unit.
