I had two houses that failed the radon test (above 4.0). Atlantic Radon responded quickly to both residences, did their own computer measurement, and installed their radon mitigation, all at a very reasonable price. The results were excellent, with one house getting a 0.7 average and the other a 0.9. I recommend them highly.
We had excellent experience with Atlantic Radon. Our house has several slabs and several structural complications that made it a non-standard case. We initially contacted a different company and were told that given our challenges, low levels of radon would not be guaranteed. Luckily, we then found Atlantic Radon. Tommy and Dan spent days studying the architectural drawings of our house to create a customized solution for us. The solution they came up with was creative and worked wonderfully. They spent extra time on designing a custom solution and extra time on installation. They also stand by their work and guarantee performance. We are super happy to have found Atlantic Radon!
