No matter how high your radon level is, your home can be mitigated and your radon can be reduced.

How can radon be reduced?

Radon mitigation can take different forms, depending on a variety of factors. That’s why it’s so important to consult a certified* radon mitigation professional to help. These professionals have the training and experience required to ensure that your home is mitigated safely and effectively. It is important to understand that not everyone can install a system, and it is important to always consult a certified radon professional.

Typically a certified* radon mitigation professional will be able to install a mitigation system in one day.

An ASD (active soil depressurization)
system being installed in a basement.

What are the steps involved in reducing my radon?

The most common type of mitigation system is called Active Soil Depressurization (ASD). This system works by sucking air (and therefore the radon) from beneath the foundation of a home and exhausting it outside. Installation of an ASD system generally consists of drilling a hole through the concrete basement floor, and then attaching a pipe so that air can be moved from the gravel and soil beneath the home. This air is pulled by a fan, and ducted out of the home through more pipe. The entire system is sealed, so that there is no communication between the system and the inside of the home.

What are the costs involved in the system?

A Radon Mitigation system can be compared to installing a heating system into your home and the cost can vary depending on the installation requirements of a house. Our data shows a radon mitigation system can range from $3,000 to $11,000.

Data from our Radon Reduction Sweepstakes Reports has shown that, for hundreds of mitigation systems installed from 2013 through 2021, the average cost is approximately $2,700.
