"After contacting two other companies unsuccessfully, I called Mitigation Tech and they came out the same day to meet with me. <br /> The owner was very professional and thorough and assured me that the system would do the job. As promised, a well-written and detailed contract for my approval came that day and the work was done as scheduled. <br /> The guy who did the work was thorough, neat and polite. <br /> Best of all, the test that was done after the system was installed came back with radon levels that were 0.2! Not bad since 3 earlier tests put the levels at between 11 and 17. I am amazed and thoroughly satisfied. <br />"

"<p>it was superb! they easiest, hassle free Radon test in town, with extremely proficient people -- very knowledgeable and very people-friendly! they took their time to explain things on the phone to me before I committed. the test came back within 10 days or so -- via email. which is very convenient. it was very clear as it is, but I like talking through it and get advice. they were instantly available to discuss. they gave me future tips to keep on top of all things Radon related. </p> <p>I have to say that all this comes to be after 3 months of many back and forths with 3 other companies -- none of the other companies could be bothered to schedule a time, and those who did, never showed up.. many times over. I don't know why I was so patient with them and I wish had discovered Environmental Testing & Research Laboratories much sooner.</p> <p>Really highly recommend them!</p> <br />"

"George Cline called me back the same day I left a message and we set up a time for the equipment to be placed in the basement.  He came at the designated time, left the equipment for 48 hours and picked up at the designated time.  He explained the results to my mother at the time of pick up as I couldn't be there and then followed up with a call to me.  I was very happy with his professionalism, courtesy, promptness in returning my phone call and how quickly he was able to come and perform the testing.  He emailed the results later on the same day that he picked up the equipment and provided the name of a remediation business since the result was above the federally recommended limit. <br /> We were VERY happy and would recommend him. <br /> <br />"

FAQs for radon gas testing projects in Rochester, NY

Radon is the second leading cause of lung cancer in the U.S. The gas seeps through cracks in foundations and collects in basements and other low areas. Once you breathe it in, radioactive particles lodge in lung tissue and do long-term damage. Because you can’t see or smell radon, the EPA recommends testing your home every two years—and after major renovations—to keep your family safe.

Yes—every home should be tested. The EPA advises doing it at least every two years and any time you remodel, buy, or sell. On average, one in 15 houses nationwide sits above the recommended limit, and the only way to know where yours stands is a formal test. The equipment simply measures gas levels and won’t change your indoor environment, so the process is completely harmless.

Certified radon professionals—often home inspectors or dedicated radon mitigation contractors—handle testing. These radon testing professionals follow EPA protocols and use calibrated instruments to check levels throughout your house. Hiring a certified radon specialist means results you can trust for real estate deals, insurance requirements, and, most importantly, your family’s health.

Inspectors specialize in measuring radon gas levels, while licensed mitigation contractors design and install the systems that remove it. If your test comes back high, your inspector can point you to a qualified mitigation pro who will size and install the right fan, piping, or other equipment to bring levels down.

No—standard home air purifiers don’t touch radon. They’re built to trap dust and pollen, not radioactive gas. If testing shows high levels, you’ll need a dedicated mitigation system that vents the gas from beneath your home to the outdoors. Relying on a room purifier alone won’t keep your indoor air safe.

Opening a few windows in your home might dilute radon for a short time, but the gas seeps back in as soon as they’re closed. For a lasting fix, you’ll need a professional mitigation system—often a sub-slab depressurization fan—that pulls radon from beneath the foundation and safely vents it outside.
