Do You Need To Test For Radon

Real Estate Broker/Owner with HomeRome Realty 410-530-2400 311291


When selling, there are many questions about the various inspections to choose from. One is Radon, and what is it? Do we really need to spend the money on another test?




When looking at a Maryland Radon map, all counties have some higher than acceptable levels.

I heard the public say; I don't believe in that test, not necessary, not going to pay for that. That's okay as long as they are informed and educated.

 If you are concerned, get it tested.


What is Radon?

Radon is a colorless, odorless gas released deep underground from uranium's breakdown millions of years ago. It seeps into the tiny cracks in the basement or foundation. The highest acceptable level, before remediation, is .4 picocuries.

Some will say there are no safe levels of radon. Hard to get away because it in the outside air. The good thing is that the testing is not costly, around $100, and most of the time, the remediation is less than $1500, not a reason to let this be a deal-breaker.

If your property tests with radon levels above four, what do you do? Check the contract. Did the buyer choose to accept, pay to correct the levels, walk away, or allow the seller to correct?


How is radon lowered?

It is a pretty simple, clean system that can be done in a day. If there is a sump pump, a small fan is inserted,  submerged, sealed, and a pipe that will go from the pump above the roofline that will constantly remove the radon from underground.

  There is a U-shaped tube with colored liquid to continuously show if the system is working. The fluid level is unlevel if working and even if not.

When I first started in real estate, radon tests were mandatory but after about two years we never had to have them again because in our area there is no radon and the test was found to be a waste of money.

Morning Margaret.

I can't recall when I saw a radon test lately.  There is a town in our county that has it's fare share.  Otherwise, most don't test for it, pity

Hello Margaret - radon testing is another one of those things that seems to be very location specific.  Over the years, I have had buyer clients ask about it(who are now relocating after living in an area where it is more prevalent than in the new chosen area).  Information is powerful but over the years, I don't recall hearing of any residential property buyer in our general area who has ordered a test.

Good morning Margaret. Radon is a bigger issue than some realize. One solution is open the windows and let the breeze lower the level. Problem is most areas have unfavorable weather for that simple procedure. Enjoy your day!

Radon tests aren't that prevalent here in Sacramento.  The incidence of it is low.  In fact, in all my years of being an agent here, I've not seen one test come back positive!
