I just spent in excess of $1000 on 5 air samples and an inspection report. The report shows elevated levels of Penicillium/Aspergillus (2700 spores/cm3 -1st bedroom, 2,300 - 2nd bedroom, outside control - 0) and Cladosporium ( 5,600 spores/cm3 - 1st bedroom, 3,600- 2nd bedroom, outside control - 2,200). The mold inspector now wants to test 5 (!) more air samples in the house. He is also recommending professional remediation on the bedrooms.
From what I understand, the CDC and EPA do not recommend air sampling. I don’t see the point in more air testing. The house is 100 years old. We know it has moisture issues, because we live in the foggy part of California. The windows are also single pane and the unit has very old wall to wall carpet. We have not been provided a real explanation as to the cause other than that there have been minor leaks in the building (these were always fixed), and that there is no primary cause of the mold. It is a rental property and the occupants do not take care of it. There is obvious mold growth around the window sills, glass, and frames. It has been recommended that we install double pane windows and rip out the carpets.
My questions to you inspectors - what value will more air testing do? It’s obvious there is a mold problem, at least on the windows. Obviously, air testing by the windows in other rooms (which is what they are proposing) will show elevated counts. Couldn’t we strip the carpets and install double pane windows in the rest of the house and do without the pricey professional remediation. I don’t see the need for it. Is the inspector just trying to CYA, because tenants are complaining that they are “sick”? And yes, I know mold is gold.
