Frequently Asked Questions


Radon mitigation systems can be viewed as radon prevention systems. These systems capture radon gas from the soil below homes and buildings, venting the gas into the air above the structure. This prevents radon gas from accumulating in the home where it can be dangerous for people and pets to breathe.

Most radon mitigation systems are installed by routing a series of PVC pipes from a collection point in the basement, slab or crawlspace. A specialized radon vent fan is installed to create a permanent vacuum within the pipes. Some radon systems are installed on the exterior of the home or building. Some radon systems are installed through the attic and exhaust above the roof. THERE IS NOT A ONE-SIZE-FITS-ALL RADON SOLUTION. Make sure that you are aware that for a radon mitigation system to properly work to reduce the levels as low as possible, it must be designed to the unique features of each particular home or building.

What is Radon?

Radon is a gaseous, toxic, colorless, odorless and tasteless radioactive element formed during the natural breakdown of uranium in soil, rock and water. Radon can seep into your home through breaks in the foundation and can also contaminate well water. Tens of thousands of deaths per year are attributed to radon exposure. Radon is the second-leading cause of lung cancer (next to cigarette smoking). A simple test can save lives.

Should I steer clear from buying a house that has tested high for Radon?

If the radon levels (in the home you are considering for purchase) are high, don’t let that dissuade you from buying the house. Radon levels can be reduced with a radon mitigation system.

What is a Radon Mitigation System?

The most common method of radon mitigation is called Active Soil Depressurization (ASD) system. An ASD Radon Mitigation System is basically PVC piping attached to an in-line radon fan. The piping typically begins below the lowest floor of the structure’s foundation (basement or crawl space) and extends upward to an exit point above ground level. The radon fan is mounted in an inconspicuous location on the exterior of the home or in an attic space (or sometimes in the garage). When radon is released into the atmosphere, it is no longer hazardous as it is diluted by the outdoor air. Radon is only lethal when trapped indoors. We are certified by the NRPP (National Radon Proficiency Program) and will thoroughly explain the best method to protect your family.

Is having a Radon Mitigation System installed expensive?

It’s hard to put a price on a potentially life saving device, but radon mitigation systems typically cost between $899 and $1,200.

Why should I install a Radon Mitigation System?

Radon is a potentially life threatening gas, known to cause lung cancer. Installing a radon mitigation will be one less thing for you and your family to worry about.

Does radon affect any one type of home more than another?

Radon has been found in all types of homes, from homes with basements to homes with crawl spaces and concrete slabs poured under them. The only way to know for sure is to test.

How long does it take to install a radon mitigation system in my home?

The average install typically takes 3-6 hours.

My neighbor tested for low levels of radon. Doesn’t that mean my home will too?

No, radon levels vary from home to home

I have lived in my home for a very long time. Why should I install a mitigation system now?

You reduce your risk of lung cancer when you reduce radon levels, even if you have lived with a radon problem. It is never too late.

Who tests for radon and why?

Frequently, buyers of real estate are testing for radon to protect their investment. It is becoming more common for homeowners to test their homes as well, to protect their families..
