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. 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.  There is no safe level of radon exposure.  In fact, the EPAs action level of 4 piC/L is still 35 times higher than the allowed exposure from a radioactive dump site and 1000 times greater risk than any other EPA carcinogine.  It's believed be the number one cause of lung cancer amoung non-smokers.  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 ceiling 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.  However, in some cases, the suction will need to be drawn through more than one area.  This can be accomplished through multiple suction points or more effectively through tying into an interior drain tile system.

If you have had water seepage issues, you can have a radon mitigation system installed along with a drain tile system, for little more than that of a drain tile system alone.  An interior drain tile system may also be critical to the functioning of the mitigation system.  Sub-slab saturation may  hinder the ability of the system to draw an adequate vacuum throughout the slab area.   

In most cases this system can be installed quickly and at a reasonable cost ($1300-$1500).  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, hyrocarbons and other contaminates.  

Free Radon Test Kit and Estimate

In most cases, unless you've previously tested, we will mail out a free radon test kit, before an in person estimate.  It's very easy to use.  The kit comes in an integrated postage paid mailer.  When your ready to start the test, simply open, place in the lowest level living space, wait between 3 and 7 days, seal it up and drop it in the mail.  Once the sample has been mailed out, results should be available in about a week.  If you would like us to come out and test for you, we would be glad to do so, but there would be a fee. Order your free test kit here.

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." Order your free radon test kit today.

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.
