We're under agreement on buying a new house. The Radon test came up at an average of 4.4 pCi/L which is above EPA levels of 4.0 pCi/L. Apparently the seller did not leave the windows closed during the test and the levels fluctuated between 0.5 and 15.7. We've asked for a re-test. There was a mitigation system installed in '13. Our realtor is downplaying it. Should we ask for a week long re-test? Anyone have experience with this type of thing? We have a 1 yo so we're concerned. Is this a deal breaker or no big deal?
