Selling a House With High Radon Levels in Connecticut
A radon test over the action level can slow a Connecticut sale. Here is what it means, what mitigation involves, and how CT MAX handles it.

Start with the address. A CT MAX buyer calls you back, and your written number follows the walk-through.
What a high test means
Radon is a natural radioactive gas that seeps up from soil and rock. Parts of Connecticut have elevated levels. The U.S. EPA recommends fixing a home when indoor air tests at 4 picocuries per liter (pCi/L) or higher. Radon can also be present in well water.
How it is fixed
Most air radon problems are solved with a sub-slab depressurization system: a pipe and fan that pull gas from under the basement floor and vent it above the roof. Water radon needs a separate treatment system.
How CT MAX handles it
Radon is one of the easier problems to price. We include mitigation in your MAX Offer, and you do not need to install a system or retest first.
Common questions
Do I have to disclose a radon test?
Connecticut’s disclosure form asks about radon testing. Share any results you know about.
Is high radon a reason a buyer walks?
It can be, which is why many sellers take a cash offer instead.
What about radon in the water?
We price that too.
