What is radon mitigation?

Radon mitigation is the process of reducing radon gas concentrations inside a home or building to safe levels using sub-slab depressurization, ventilation systems, and sealing techniques. Air Sense Environmental is St. Louis's IEMA-certified (License #RNM20232346) and NRPP-certified radon mitigation specialist, serving homes and commercial properties across Missouri and Illinois from our Edwardsville, IL headquarters. Every mitigation project ends with a post-mitigation test verifying your radon levels have dropped to the EPA action level of 4.0 pCi/L or below — most of our installations land well under 2.0 pCi/L.

If your radon test came back high — or you're a home buyer whose inspection just flagged elevated radon — you don't have to figure this out alone. Call 314-664-9807 for a free in-home estimate. We've installed 132+ systems across the St. Louis metro with five-star reviews on every one of them.

Components of a radon mitigation system may include

Sub-Slab Depressurization (SSD) System

This is one of the most common types of radon mitigation systems. It involves installing pipes and a fan in the building's foundation to create a vacuum effect, drawing radon gas from the soil beneath the building and venting it safely outside, away from occupied areas.

Monitoring and Alarm Systems:

Some advanced systems may include monitoring devices or alarms to provide ongoing information about radon levels or to alert occupants in case of system malfunction. Air Sense is a dealer for all Air Things Monitors. Check the bottom of your invoice for discounted pricing on long term radon monitors for your home and system.

Crawl Space or Basement Ventilation

For buildings with crawl spaces or basements, moisture barriers act as a deterrent to soil gases, including radon, by reducing their movement from the ground into the crawl space and subsequently into the home. Radon can migrate as a gas through porous materials, and a properly installed moisture barrier can help limit its entry.

Sealing and Caulking

Mitigation may also involve sealing cracks, gaps, or other openings in the foundation or floors to prevent radon entry.

Radon Exhaust Fans

Fans are used to create negative pressure within the system, ensuring that radon gas is effectively pulled from the soil and expelled outside, away from the building.

Sump-Pump Mitigation

In properties with sump pumps, Air Sense will repair/replace the current lid to provide an air tight seal from the sump pit to the open atmosphere inside the home.

Key Benefits of a Professional Radon Mitigation System

Once high radon levels are confirmed in your home, the most important next step is to take action. A professionally installed radon mitigation system is the only reliable way to significantly reduce radon concentrations, providing a permanent solution for a healthier indoor environment.

Protect Your Family’s Health:

This is the most critical benefit. Radon is a leading cause of lung cancer, and a mitigation system reduces radon levels to a safe concentration, significantly lowering the health risks for you and your loved ones.

Increase Your Home’s Value:

A home with a radon mitigation system is a major selling point. It shows potential buyers that the home is safe and has been responsibly maintained, which can be a significant advantage in a real estate transaction.

Enjoy Total Peace of Mind:

Stop worrying about the invisible threat of radon. A properly functioning mitigation system works 24/7 to protect your home, giving you the confidence that your family is breathing safer, cleaner air.

Improve Overall Indoor Air Quality:

In addition to venting radon, the system can also help reduce moisture levels and other soil gases from entering your home, which contributes to a less humid and healthier environment.

Investing in a radon mitigation system is a direct investment in your family’s long-term health and your property’s value. Contact Air Sense Environmental today to discuss your custom solution and schedule a free estimate.
