"The radon mitigation unit was installed quickly and I was impressed with the crew. After installation, I found my refrigerator was not working. Called an electrician who had to fix the outlet which blew out due to the installation of the mitigating unit. Also, the electrician told me that the unit was installed with the wrong gauge of wiring to the unit and had to replace it to make it up to code. Although Matt repaid me for my out of pocket fixes to his work, he never did come back and finish the final phase which was to test the mitigation unit although contacted on several occasions. I will say this, nice guy, but I think he is so busy he does not know which project to tackle next and forgets that he still has some others left hanging."

Radon Detection and Reduction questions, answered by experts

DIY kits are available for basic testing. Professional services provide comprehensive results and recommendations.

Testing every 2-5 years or upon adjusting occupancy or structural changes maintains safe environments.

Professional radon detection involves placing test kits in the lowest lived-in level of the house for a period, usually 48 hours to several months, followed by lab analysis of collected data.

What is radon? It’s a radioactive gas that naturally occurs in the ground, forming as uranium and thorium decay. It has no color or odor, so you don’t know if it’s seeping into your building’s foundation. Regular exposure to radon gas increases your chances of suffering from lung cancer. Radon testing measures the air inside your house for the presence of radon gas. If detected, the test will measure the severity of radon levels in your home’s air.

If your home has a sump pit, you can integrate it with a radon mitigation system. You can accomplish this by sealing the pump cover with an airtight lid that accommodates radon vent pipes and sump pump hoses. This allows the vent pipe to redirect the radon gas outside of your home.
