I’m selling my house. The buyer had a mold remediation specialist in to check for mold. They are also a waterproofing company. We subsequently got slapped with a report that stated we had an ongoing water problem in basement, and that a full french drain system is needed (we already have a french drain leading to a sump pump – no mold found btw, and the original inspection said the basement was dry). I will be speaking with the waterproofing company soon. What questions can I ask to make sure the company clearly articulates the issue and reason for suggested remediation?
