How much does it cost to fix radon?

Radon is a harmful, radioactive gas that is present in soil and rocks. Outdoors, it dissipates safely into the air and is of little concern. If it's inside your home, though, you and your family are at risk for serious health effects. Long-term exposure to significant radon levels can lead to lung cancer. The radioactive particles in the air enter your lungs and harm the cells lining them. Given enough time, your lungs can become irreparably damaged.

Any home with high-level radon testing should resolve the situation through radon mitigation.

Radon is only detectable through testing, commonly known as measuring. It measures your home's level of radon in picocuries per liter of air, written pCi/L. There are several types of tests on the market, some of which you can find at your local hardware store. The more reliable tests are long-term and require a certified professional to perform.

Typically, radon testing is done through a testing device placed in the lowest level of living. Many homeowners assume the device is placed in the lowest level, crawlspaces, and basements, but what you want to know is how much radon gas you're breathing in, not how much is below your home.

Most foundation types are susceptible to radon, the exceptions including houses built on stilts and mobile homes without skirting. If your home is built on top of a crawlspace, basement or slab foundation, radon in the rocks and soil beneath your home will find its way into the living space through suction, new homes and old homes alike.

As radon is the second-leading cause of lung cancer, removing the dangerous gas from your home is of the utmost importance.


The best test results are under 2.0 pCi/L, though anything under 4.0 pCi/L is considered ideal. There are no safe levels of radon, but the ultimate goal of a radon mitigation system is to bring your dwelling down to the average outdoor level of 0.4 pCi/L.

A radon mitigation system typically consists of piping and a motorized fan placed in the lowest level directly into the rocks and soil beneath the home. The fan creates suction to direct the flow of radon gas through the piping where it is safely vented outside at the top of your house. When the gas hits the outside air, it dissipates and no longer poses a risk to your family. Installation takes an average of three to four hours.


The initial testing costs vary based on the type of test used and whether you have a trained professional perform it. Once your test results come back to you, you have the choice on whether you install a mitigation system. The U.S. EPA recommends mitigating your radon at a level of 4.0 pCi/L or higher.

The cost of the mitigation system likewise varies, based on factors including where the fan needs to be placed, i.e., crawlspace, basement, fully-finished lower level, etc. On average, the cost is between $800 and $1,200. After installation, you can expect an annual running expense between $100 and $125.


How lower radon levels: The process of fixing radon can seem daunting at first but remind yourself of the investment you're making in yours and your family's future. Radon is extremely harmful to the cells lining your lungs, and long-term exposure to elevated levels can lead to lung cancer diagnosis five to 25 years after exposure. So even after you move out of a home with a high level of radon, you can still develop lung cancer later on down the line, though not everyone who is exposed will get lung cancer.

The U.S. Surgeon General strongly recommends that every home perform testing, so regardless of whether you live in a radon ‘hot spot,' start with having your house tested.

If your radon level is concerning, consider placing a mitigation system in your home. Use a certified professional for your measuring and system installation.
