According to the latest EPA's Assessment of Risks from Radon in Homes in the United States, epidemiological evidence shows a clear link between lung cancer and high concentrations of radon, with 21,000 radon-induced U.S. lung cancer deaths per year—second only to cigarette smoking. www.epa.gov/radon/health-risk-radon The map at right is based on the EPA's average in home radon levels found.  Individual homes may be higher or lower.  

Zone 1 -Greater than 4 pCi/L

Zone 2 -Between 2 and 4 pCi/L

Zone 3 -Less than 2 pCi/L

In home radon levels are a serious concern.  Radon exposure is the number one cause of lung cancer among non-smokers.  The EPAs has set an "action level" of 4 piC/L, but even that level is still many times higher than the allowed radiation exposure from any other source.  There is no safe level of radon exposure.  It is our goal to reduce radon levels as much as absolutely possible, in every home.


According to the EPA, the most effective and reliable technique for radon reduction, is Active Sub-slab DepressurizationReductions of up to 99% can be achieved.  We specialize in the Sub-Slab Depressurization method.  It offers a permanent and effective solution in which we can guarantee the results.

Sub-slab Depressurization


The  idea of  Sub-slab   Depressurization,  is  to provide a constant vacuum pressure under  the basement  slab. This  is accomplished through  the  use  of  a specially designed vacuum  fan  connected  to one or  more suction points.  The vacuum fan can be installed in an attic,  garage space or on  the exterior of the home. The fan cannot be installed in the living space and the venting must extend 12 inches above the roof line.

In order for the system to be effective, suction must be dispersed under as much of the slab as possible.  If there is a good coarse base under the slab such as crushed gravel or course sand, a  single suction point may be adequate.  Otherwise there may be a need for two or more.  If there is an existing interior drain tile system, we can simply install an airtight sump lid, and tie directly into the drain tile system.


If you have had basement water seepage issues, they should be addressed.  Sub-slab saturation  may  hinder the ability of the system to draw an adequate vacuum throughout the slab area.  You can have a radon mitigation system installed along with a drain tile system   When incorporated together, the radon mitigation is highly effective and also greatly lowers basement humidity.

In most cases this system can be installed quickly and at a reasonable cost.  Not only will it reduce radon levels, but it can reduce water vapor intrusion possibly eliminating the need for dehumidifiers.  It may lower other soil gasses as well, such as: methane, hydrocarbons and other contaminants.  

Radon Testing / Estimate


Unless you've previously tested, we will need to establish your base radon levels.  You can either, have our technician come out to test or you can order a DIY test kit.  If you hire us for Radon Mitigation, our testing fee will be refunded. 

If you have any more questions or concerns about radon, please visit the EPA's website.  A good place to start, is by reading, "A Citizen's Guide to Radon.


Note: Radon testing and disclosure, are already required for home sales in many areas of the US.  Even in areas where it is not yet required, many lenders will insist on it for approval of financing.
