Realtors Info

Houses today are becoming more complex and in today's tough market, lenders are requiring more information from borrowers and more information about the property. Home buyers and sellers are much more aware of radon today and with continuing campaigns to raise pubic awareness from organizations such as the EPA, Minnesota Department of Health and the American Lung Cancer, that awareness will only continue to rise. These and other organizations have been responsible for having January declared National Radon Month and for new building codes requiring new homes to be built with radon reduction systems.

Having a home tested for radon before the sale is becoming the standard now and it can protect both you and you clients. In fact, a home that has been tested and found to have low levels of radon or that has been mitigated can be a strong selling point. As the realtor, you should be knowledgeable about radon testing and mitigation since your client will probably look to you for information.

If you are representing the buyers, make sure the home is safe and have it tested. If the levels are high you can negotiate with the sellers so your client doesn't absorb all of the costs associated with mitigation.

If you are representing the sellers, have a test done early so if the levels are high, your client can take care of it in a timely manner, before it scares away a potential buyer.
Nobody wants high radon levels to cause a buyer to back out of a sale, so why not have a test done a soon as possible. If the levels come back low you can use that as a selling point and know it will not be a problem at closing. If the levels do come back high, you have time to decide what to do and to take action.



Things to look for in radon testing:

Who performed the test?
Was it a third party non-biased?
Are they certified (check the MN Dept. of Health web site).
What type of test did they do?
Continuous radon monitor
What area was tested?
Should be in the lowest livable space.
When was the test done?
Winter or summer. Levels tend to be slightly higher in winter.
How are the results shared?
Buyer, seller or both parties.
Who will pay for testing?
Buyer or seller.
How will the results be used?
What level will trigger mitigation (usually < 4.0 pCi/l)?

Here are some things to look for in a good mitigation system:

  • A warning monitor and label for identifying the radon system.
  • A U-tube manometer for checking the pressure.
  • Vent pipes should be a 4 inch PVC that exhausts at least 12 inches above the roof.
  • Sump basket (if there is one) should be sealed with silicon to allow for future access along with all cracks and penetrations in the basement floor.
  • Joint where basement wall meets the floor should be sealed.
  • A disconnect for the radon fan which can be either a switch or a plug to allow for easy replacement in the future.   Fan is required to be in an area outside of the living space, an example being  the attic).
