This is a follow-up from the home remediation we started on December 4. We completed the job, and it turned out to be a larger issue than we anticipated. We found 3 dead birds in the HVAC ducting. There was a lot of mold mixed in with the dust in the HVAC system. This mold is caused by excess humidity, as the moisture source, and the organic particulates in the dust as the food source for mold. We took extra time on the HVAC ducting so that we could properly remove the contaminants and disinfect both systems. We used a whip system from Nikro to clean the ducts, along with a high-powered vacuum system to create a negative pressure to pull the dust to. For a home this large, along with the number of registers, both supply and return, two techs spent a total of two days ensuring the system was as clean as possible and fully sanitized. We found a lot of mold on the contents in the basement and properly cleaned them. We spent most of the time air scrubbing, vacuuming, and wiping surfaces. We used a blower in each room to kick up hidden dust and had a HEPA and carbon air scrubber running along with a blower and ducting running out a window to create a negative pressure and pull the particulates out. We had to do this process several times in some of the rooms due to the amount of dust this process generated. Here is a picture of some of the dust in one of the rooms. Once this process is completed, we HEPA vacuumed all porous surfaces and wet-wiped the non-porous surfaces with our all-natural enzymatic cleaner. Once complete, the blower could not kick up anymore dust. This process is part of our enhanced full home disinfection and environmental reset.
Overall, I felt like the job went extremely well and our post-testing confirmed that. During the initial inspection, several air samples taken in the basement were well over 100,000 spores per cubic meter and in the master bedroom the counts were over 20,000 spores per cubic meter. Upon completion, the total fungal counts in all samples, throughout the entire home, were under 500. This is a successful remediation. Our all natural solutions to remediate mold really work.
