What happens when they "fail" the test? Is there a "fix", or just a cancel of the sale, and move on to the next potential buyer? Does the local "govt" put a tag on the house and "quarantine" it?

Beenthere, Normally the contract is still good as long as the buyer and seller agree who pays to fix the radon problem. In the case of my neighbor he agreed to pay up to $800 for the fix. I guess anything over that is the buyers responsibility (?). If the house should fail the test they have to put an "exhaust fan" over the sump pump pit, sealed tight and then vented to the outside. This usually costs from $800 to $1600 depending on how bad the radon is. My neighbors level came in at 5. Anything above 4 fails. Since he already had the rough in for a passive radon system his cost was only (only $500 [img]/forums/images/icons/mad.gif[/img] )I understand some houses go into the 50's. No the "govt" does not tag the house, not yet at least. [img]/forums/images/icons/crazy.gif[/img]
