"Caught a sketchy electrical panel and a slow leak — used the report to knock $4,200 off the sale price. Worth every penny."

Common questions

Answers before you book.

How long does a radon test take?
48 hours minimum per EPA protocol. We deploy a continuous monitor, leave it running, and pick it up with the results emailed within 24 hours of retrieval.
What radon level is safe?
The EPA action level is 4.0 pCi/L. Anything above that warrants mitigation. Many southern Minnesota homes test between 2 and 8.
Do you mitigate radon too?
We test only — that keeps us unbiased. If your test shows elevated levels, we refer trusted local mitigation contractors.
