"Be careful. I called to have a radon mitigation system installed and the sales rep on the phone took down the information and scheduled the appointment. I was upfront about an interior drain being installed. When the technician arrived, he said he'd be happy to install the system, but that it would be worthless because of the interior drainage system. I then received a $200 invoice for the site visit. Frustrating scenario to have a sales rep schedule the appointment, knowing full-well that I had an interior drain, and then the technician tell me there's no point to install a mitigation system, but then charge me for the inconvenience of it all."
