"The service was for Radon Mitigation in our home that had higher than acceptable Radon levels. The work was professionally done, and care was taken to protect carpeting etc during their work. The crew updated us home owners as they did their work and asked permissions for needed modifications to the house. I would recommend this company to anyone looking for quality workmanship, congenial communication and moderate pricing."

"I contacted Radiant Radon through Angi and Jonathan responded within minutes. We spoke over the phone the next day and I was given a firm price. The work was completed within a couple of days and Jonathan was super communicative and did a great job. I have an air quality monitor and the radon level dropped from 9.0 to below 1.0 within 24 hours. Overall - awesome service, great pricing and a great guy!"

Radon Detection and Reduction questions, answered by experts

The natural breakdown of uranium in soil, rock, and water can cause radon to appear in a home. The gas seeps into homes through cracks in foundations, walls, or floors, as well as through gaps around pipes or construction joints. Radon levels are influenced by soil composition, building materials, and ventilation. Poorly sealed or airtight homes can trap radon, allowing it to accumulate.

Installation typically takes 1-2 days, depending on the system and property layout.

While DIY testing is possible, abatement generally requires professional installation to ensure efficacy and meet safety standards.

Ideally, no one will live in a house with elevated radon levels, as prolonged exposure increases the risk of serious health issues like lung cancer. However, homes with radon can be made safe through mitigation systems, such as active soil depressurization. Testing for radon regularly and addressing high levels helps ensure a safe living environment.

Mitigation can take several days depending on home setup, equipment accessibility, and achieving effective diffusion system sealed efficiency.
