Radon Testing

Radon is a cancer-causing natural radioactive gas that you can’t see, smell or taste.

Approximately 21,000 death are attributed annually to this silent killer.

What Is Radon And Where Does It Come From?

Radon is a naturally occurring radioactive gas. It is produced in the ground through the normal decay of uranium and radium.

What Makes Radon Dangerous?

Radon decays to polonium & lead particles that you breathe; these radioactive progeny lodge in your lungs, bronchi, and trachea. The radiation disrupts and mutates cells and can, eventually, result in lung cancer.

How Does Radon Get Into Homes?


Radon moves through small spaces in the soil and rock on which a house is built and can seep into a home through dirt floors, floor drains, sump pits, cracks in the foundation and basement floor & up through hollow core block foundation walls. Differences in air pressure between the basement and the soil beneath the home also play a part in the migration of radon gas.

What Level Of Radon Is Considered Hazardous?

The EPA has set the level of concern at 4 picoCuries of radon per liter of air (4 pCi/L). At 4 pCi/L we accumulate about 10,000 radioactive atoms in our lungs, trachea, and bronchi every minute.

Can My Home Be Fixed If High Radon Levels Are Found?

Yes! Radon is one of the easiest of all environmental concerns to repair. Sometimes, all it takes is sealing up cracks and openings in basement floors, foundation walls, openings around pipes, etc. If a crawl space is present, often times placing a vapor barrier (plastic sheeting) over the bare soil will cure the problem.  In other cases, it may be necessary to install a special suction system that draws air from under the basement floor and exhausts it to the outside. This is called a sub-floor de-pressurization system. Whatever the methods used, a high radon level can almost always be reduced easily! Mitigation prices to lower radon levels can range from $500 to about $1000. Be sure the contractor is listed with the EPA's Radon Contractor Proficiency Program.

How Can I Find Out How Much Radon Is In My Home?

Have your home tested! Currently North Carolina does not have any licensing or certification requirements however the EPA suggest that you have your home test by an NEHA-NRPP certified provider to ensure the test is performed within EPA standards. Two types of tests are available, short term and or long term. Most people will have a short term test performed and if the levels are higher than the recommended EPA levels then another short term test is performed or a long term test is conducted. Short term test typically take 2 - 4 days but not greater then 90 days. Long term test are a minimum of 91 days using a continuous monitoring system. Again, short term tests are adequate for most homes.

How Much Will It Cost?

Prices range from $125.00 (charcoal canister) to $199.00 for more accurate testing. Like everything else, you get what you pay for... the majority of inspectors performing these tests have little to no training in Radon (much like home inspectors never working in the home building industry).

Radon gas is a serious health issue for you and your family, we highly recommend that you give us a call to inform you if there are dangerous levels of Radon gas in your home.
