Radon Reduction System Quality & Craftmanship

Each system is custom designed to be the best possible solution for both the home and the homeowner. Quality and craftsmanship is crucial to maintain the cosmetic integrity of the home. Poor cosmetics and choice for system placement can have a drastic affect on the value of your home.

In most cases, Radon is not an issue that should keep anyone from buying their dream home. Radon is everywhere and in every home, the question is how much. A home with a radon system is likely to have better air quality than the same home without a radon system, (this statement is made without regard to radon levels).

  • Even very high levels can be reduced to acceptable levels.
  • Sub-Slab Depressurization is used nearly 99% of the time to remedy Radon problems.
  • Most homes can expect results between 1-2 pCi/L. Effectiveness is expected for as long as the system fan is operational.
  • There are almost always several options for properly fixing the Radon problem.
  • The easiest and fastest is not always best, choose a quality contractor.

Radon systems remove the soil gasses prior to their entry into the building. Along with the reduction of radon and soil gas is the added benefit of removing a lot of the humidity and moisture found in basements.



The first step to help ensure the safety of you and your family’s health and safety is to have your home tested for radon. At St. Louis Radon, our professional testers deploy the latest in computerized electronic real-time radon monitoring technology to provide you with a comprehensive report, including a complete visual graph of radon level data points as recorded over a 48-hour sampling period.

If testing indicates levels of radon that require action, our team of engineers and technicians will design and install a custom radon mitigation system to safely and effectively redirect radon and other soil gasses out of your home. We also take additional measures to seal and close other possible breaches in the foundation that could let soil gasses into the through cracks or drain tiles systems.

New Construction

With new home construction projects, it is crucial to determine the level of radon that may be present in the soil before the home is built. It’s also critical to have the new home retested for potential radon concentrations immediately following occupancy. We also highly recommend installing an Active Dampness Control System (ADC) with every new build.
