Radon Testing and Mitigation


Radon, a colorless odorless gas, is found in all homes and is the second leading cause of lung cancer in the United States. We have been trained to test for elevated levels and can alert you to correctable problems. We use state of the art equipment and efficiently test for this invisible menace.

About Radon Testing

The radon detectors we use are Radon Sentinel 1030's. The latest creation in radon testing from the Sun Nuclear corporation. The 1030's have 6 detectors for higher sensitivity producing reliable data with less variation (15 cph per pCi/L sensitivity). The 1030's can be plugged in or battery operated for areas without power access. We regularly do simultaneous testing to assure us of precision and we have them calibrated at the required intervals to insure that we have the most reliable test results we can.


As many as 1 in 15 homes can have radon levels above the action level of 4 pCi/L. This problem is always correctable with a number of radon mitigation solutions. We check for possible radon entry points, inspect existing mitigation systems and test for radon levels in the home.



Radon Mitigation

Red River Home Inspectors offer radon mitigation. Radon mitigiation is an active system that lowers radon levels. Eric and Brady have attended the Midwest Universities Radon Consortium (MURC) and are MURC certified. They are also certified by the Natinal Radon Proficientcy Prorgam (NRPP) for radon mitigation. We are listed on the Minnesota Department of Health's website as radon contractors/mitigation service providers. For a full list of qualified radon mitigation providers click here. If you have tested your radon and it is at a level at or above 4.0 pCi/L there is a way to lower that level.

Red River Home Inspectors can inspect your basement or crawl space for possible radon entry points and create a plan for lowering your radon levels by sealing entry points and installing a subslab or submembrane depressurization system. The radon will be redirected above the roof line where it will dissipate in the outside air. We offer free estimates and a system can typically be installed in 1 day. Following installation, the system will run for 24 hours and then be tested to ensure the radon has been reduced to a level under 4.0 pCi/L (the EPA's action level). In MN, new residential construction is required to have a passive system in place. If the passive system fails to lower the radon efficiently, we can convert passive systems into active radon reduction systems to reduce the radon levels.
