TESTIMONIALS -Over 300 5-star online reviews

"They took the time to thoroughly explain how radon encroaches into a home and how their remediation resolves that. They responded to our query quickly, provided prompt service, were very quick and comprehensive with their installation, and also did a neat/tidy job. Most importantly our levels dropped from 12-14 to sub 1 in two days exactly as they assured us (we have a large home with a finished basement where two samples were required). We highly recommend them."

"WOW!!! I am so pleased with the job Inspect It Chicago did in my home. I called on Monday, and they got me in for a radon mitigation install 3 days later. Steve and his crew were very professional, and a delight to work with. The entire job took only 2.5 hours, and my radon levels dropped from 14 to 0.7 within 24 hours of the installation. The price was right too, as I had received higher quotes, from other mitigation companies. I HIGHLY RECOMMEND this company. Thanks, for all your help and hard work!!!"

The guys did a great job installing the mitigation system. Their price was about $100 higher than another company, but they were able to schedule me much sooner and got the job done in about two hours; sometimes you get what you pay for and when it comes to the health and safety of your family, don't be a cheapskate! When I hired another company to test radon after the installation the living room when from 4.2 to undetectable and the basement went from 7 down to 1. I definitely recommend this company for radon mitigation

"I've actually had Inspect It install 3 different systems for my homes in the last year. They are professional and use top of the line equipment in there installations. Their installation techniques are the very best. They have successfully mitigated extreme levels to near non existent levels in all 3 instances. I recommend them whenever possible. Top notch. The owner is very experienced and fully understands the science as exemplified in their suscesses I've experienced. A++"
