I have not been involved in a radon remediation. Yet.
Blog on.

opening windows, added an exhaust fan.
Do you know certain granite emits more? The pretty colorful reddish type.

As a former licensed radon measurement specialist, the highest I've tested was in the upper 20's. At our previous home, we had a level of 18. They came out and installed the 4 inch suction pipe and it dropped to 12. They came back and had to "T" off the 4 inch pipe and run another two inch pipe to another section of the basement floor. The level dropped to around 2. This was due to the layout and footing of the basement floor. It's pretty common in eastern Nebraska to have higher levels. Only way to find out is to have it tested. Mitigation runs $700 to $1200 on average around here. When they mitigate, they have to get it below 4 no matter how many times they have to come back.

My house tested around 16 or 18 (don't remember the exact number). Remediation brought it down to 4ish.

Lise Howe I've only had one property that had a radon issue. It did exceed the EPA standard. The seller paid to have a venting system put into place. It was retested and passed. The property settled.

30. In our agreement of sale we specify who pays. In my case I always require that the seller pay for it or the buyer can cancel the contract.

I've had ONE radon test and I have no idea what the number was, but the buyer never mentioned it so I guess it was all clear. Not common here.

Roy Kelley , the 'acceptable' level as defined by the EPA is no more than 4 picocuries/liter. Anywhere in the USA. More info at www.epa.gov/radon.
Personally, I've seen 24! I've had inspectors tell me they've seen into the 40's. Almost always, remediation brings it to an acceptable level. My area is known for radon and I have never seen anybody need a second remediation.
An experienced company knows what to do and they do it right the first time. This is not something to trust to just anybody, by the way. Make sure you use a specific remediation company. Interestingly, some builders are now installing the 'guts' of radon mitigation systems when they pour foundations and it includes the vent pipe, too. If high radon is found later, the inline blower fan is all that's needed. It adds about $800 to the cost of a new build, I'm told.

Lise, I had a 27 reading a couple years ago, and after mitigating, it came in below 2. Have never had to do this twice.

Good morning Lise. Just over 4, in some areas that I do mortgages the are constantly high.

Four is the acceptable number. I had one at 18. Because the EPA estimates that half the homes in Colorado have readings above four, we see tests done frequently. The ones slightly high (between four and five) often the Seller won't pay. The higher the numbers, the more it leans toward the Seller paying for remediation. If done by a professional, you should never have to have the remediation redone.

We don't have this problem here. I would't even know what the numbers everyone is suggesting mean...

I have not seen it in person, but another agent reported 36! Don't know the post remediation results, but sale went through... Personally, I've had buyers back out where the levels were only slightly elevated, but still within "acceptable" norms. They did not even want to discuss remediation.

It was in the twenties on a REO and then the price dropped substanially and was for my daughter. Well under two with renediation and replacing the farmer's tiles that had been disrupted during building.
5,583,328
I think it was about 55...and a the level went under 4 after remediation....
2,310,576
I had one that came in at 19. The remediation system brought the level down to under 2.

I don't track such metrics. In any event, radon tests are not commonly done in my area. Radon testing appears to be a much bigger issue in your country.

I had a home that was almost 7 once, after remediationdropped to below 2.

It's not an issue in my area of SoCal and I don't recall from my days in New England what any particular test results were. I know some were high, and in a couple cae remediation was done by the seller

I don't have any personal experience with it yet, but CO reports on this (http://www.coepht.dphe.state.co.us/, under environment, radon, percent of indoor radon tests above 4).
The highest max percent that they show currently is from within Jefferson County and it was a staggering 1625.7, and that county has a mean of 7.26.

Lise, the highest I have seen is around 39 and the mitigation brought it down to around 2.
I hope someone weighs in from Pennsylvania as I have read that many of the tests come back in the 200-300's! WOW!
Sellers understand that it is a safety issue and I have never witnessed a seller that did not make the repairs as the buyer could walk as a safety issue in our state PA.
