I am in the middle of purchasing a house. Idea location and very desirable community. Everything is good until I did a mold inspection and was advised by my home inspector that there was a minor mold issue. 300/m3 Curvularia spores were found in the basement air sample while there were zero curvularia found in the control sample (which is outside of the house). The report abled it "slightly elevated." Our inspector still called it out. We asked the seller to remedy this. So mold remedy company came in and treated.
After treatment, we ran another test. And now, the result is 200/m3 curvularia spores. My inspector told me the remedy is not sufficient and need to do further. So I ask the sellers to do further treatment and ask them to give us a report from the mold remedy company showing remedy is effective. After the sellers have a communication with the mold remedy company, they tell us they feel our inpector's expectation is not reasonable.They want us to define what is "acceptable" result, since there is no way the number could be down to zero(not sure if it is our inspector's expectation though). They think the current result is within the normal range and shows us some information on the website saying it is within the normal range. Also, they can't provide the report we are asking for. To let us feel more comfortable, they could cut some drywalls, but that's all that they will do.
Now I don't know which direction I should go. Is it the number considering no issue? Just my inspector unreasonable expectation and our request for such a report is no reasonable? or should I just walk away? I worry that if my inspector or my expectation is not reasonable, I might run into the same situation again.
Thank you very much!
