Before and After Radon Levels
Below is a list of some of the homes where we’ve installed radon mitigation systems alongside the before and after radon levels. Nearly all listed tests were conducted in the basement levels of the home. All the before and after tests were short term radon tests ranging from 2 to 7 days in length. We can’t guarantee how far below 4 pi/L we can get the radon but our average results are below 2 pCi/L.
Please Note: The average measurement for radon in the outside air in Central New York is about 0.5 pCi/L. However it is often higher in high radon areas; I did a grab sample radon test in the backyard of an Ithaca home using an electronic continuous radon monitor placed about 3 ft. above the lawn; that average radon level in the outside air was 10.6 pCi/L. So as you can see, we often achieve indoor radon levels substantially lower than what it is in the outside air.

Another Example:
Another Example: 6 radon mitigation systems I installed in September 2018 had an average of 1.3 pCi/L for the post mitigation radon tests - those test results: 0.6 pCi/L, 0.2pCi/L, 2.0pCi/L, 2.1pCi/L, 2.8pCi/L, 0.2pCi/L. These were all tests conducted by the homeowners, using a NY State Certified test kit sent to an independent 3rd party Laboratory so there is conflict of interest by me, the radon contractor doing his own post mitigation testing to confirm acceptable radon levels.

The highest radon levels in New York are in Cortland county, with radon levels above 600 pCi/L around Tully. We've tested and successfully mitigated some Onondaga county homes in Jamesville and Manlius with radon levels over 200 pCi/L. We've also mitigated +100 pCi/L homes in Baldwinsville, Chittenango, and Brooktondale.
