Customers say: Quick response

"Professional, courteous, competitive pricing, and very responsive. The company did an excellent job installing an asbestos mitigation system in our basement. The were polite, kept the work area clean, and even more importantly, completed the task quickly and professionally. The best part is that they do not ask for payment until a post-abatement test is conducted and passes! I would highly recommend this company for your radon mitigation/abatement needs."

"Excellent, very satisfactory. Radon Brothers' rep came, saw the problem, and replaced the leaking radon exhaust PVC pipe in my basement floor. All in record time. Am very satisfied and will continue using Angi contractors."

"I waited a month before getting a test kit I called and was told there was something wrong with the Angies list orders but that I would be receiving a kit soon. It wouldve ben nice if they called me to tell me that though. The test results were quick and on par with other radon test I had done locally."

"At first not so well. I had a passive system currently installed and I was hoping making it active would solve my radon issues; note my radon levels were off the charts at around 130 pCi/L. Mike and son showed up on time and performed the work quickly and efficiently. They needed access to my attic in which they added a fan to my passive system, did some sealing around my sump and added a manometer. Total time of around 1 hour. Unfortunately though running efficiently, this only brought my readings down to around 75 pCi/L. Cost of 1st install was $765 Mike and son came back out again and installed another suction point, including drilling and installing 4" pvc, another fan, and another manometer. Total time of around 1.5 to 2 hours. Again on time and done efficiently. Both times they cleaned up everything and were respectful of my house. Luckily this time it worked, bringing my levels down to around 1 pCi/L. Cost of 2nd install was $965."

"We were extremely pleased with Ron's professionalism and his work. The system that he installed exceeded our expectations. The unit was placed in a very discreet location. Ron maintained a neat working environment and thoroughly cleaned up after the work was completed. He was extremely responsive to any questions that we had, both before and after the installation. The system works better than we anticipated. After the unit was installed, we conducted an independent radon test and discovered that our radon numbers had dropped from a 9.0 (the number before the unit was installed) to a 0.7. Throughout the installation, Ron was honest and upfront as well as personable and trustworthy. He was also very kind to our dog! We would enthusiastically recommend him to anyone looking to have similar work done to their home."

FAQs for radon gas testing projects in Harrisburg, PA

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.
