"Andrew is top notch in my book, and I am so very glad that I hired him. I was told by another professional a long time ago that I needed two suction points since I had two cement slabs, and Andrew assured me that it typically is not needed, and if it is for some odd reason it won't cost me anything more than what his original quote was. All questions answered with confidence. I was notified when he would arrive on the day that was agreed. The suction point was discussed and ultimately my own locations he selected without argument he worked with me and suggested area's that would work out. He assured me that if the levels of radon are not below 2 then he would come out again to modify the size of the fan and or add another suction point. when he started working once the suction location was agreed upon, work went very fast with his assistant outside and Andrew in the basement holes drilled suction tubing installed and vented exactly where I wanted it. Outstanding job Andrew!!!! "

Radon Detection and Reduction questions, answered by experts

Using an air purifier in your home or basement isn't an effective way to reduce or mitigate radon. Radon is an inert gas, meaning it doesn't react with other chemicals and can't be filtered the way particulates can be. While an air purifier can help improve your indoor air quality in other ways, don't rely on it to reduce radon.

A DIY kit can lessen the sting that comes with paying for a professional assessment, but these comprehensive tests are true lifesavers. Inspectors are more likely to catch all of the pollutants and hazards in your air. Plus, you’ll still need a professional to verify and act on your DIY test results. 

Some kits don’t include tests for certain air pollutants or only detect their presence, but not their levels (i.e., mold spores). If you’re willing to shell out money for a DIY kit, it’s usually better to stretch your budget slightly higher for a more detailed assessment.

Yes, most services include testing the generator to ensure functionality. Confirm with your provider.

Radon enters your home when warm air begins to rise and exits through the roof, creating a vacuum that pulls cooler air from under the foundation. Part of that air is radon, which is an invisible, odorless gas that develops naturally when radioactive particles are deep within the ground. Those particles usually come from decaying matter in soil and rocks.

Results from radon testing usually take a week to process after the test period ends, with expedited services sometimes available for urgent cases.
