I just purchased a house and had radon mitigation done after receivng readings above 8 pci/L.
During my pre-closing walkthrough and 24 hours into the radon retesting (after installing the radon mitigation system) I noticed the walkout basement door had been opened by the people who were doing mold remediation in my basement and probably had been for the first 32 hours of the 77 hour radon test. Should I be concerned? The readings with the door opened (hours 1-32) never went above 0.9. The readings increased after the mold specialists were gone but still never went above 2.0 (hours 33-77).
I would like the radon testing company to re-test. Is this reasonable?
Also, the re-test results were not professionally documented in my opinion. They sent me a ticker tape with the readings only. My address was not even on the tape anywhere.
Thoughts? I'm not concerned for my safety and it looks like they did a professional mitigation job. I just want a well documented clean bill that followed standard protocol for when I go to sell the house.
