Continuous Radon Monitor (CRM)

Following radon mitigation, post-mitigation testing should be performed. This will typically consist of short-term testing to verify that your Radon levels have been reduced to acceptable levels.

St. Louis Radon deploys continuous radon monitor testing machines, 24 hours following mitigation, for 48 hours to assure the levels of radon have been reduced to acceptable levels.

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.
