Chris was terrific to work with. Got our radon numbers down from over 5 pC/L to under 0.4! Great workmanship and excellent pricing.

Our neighbor hired Chris and recommended him. And we will absolutely recommend him to anyone! Great price. Excellent quality of work. The final product and basement is clean and done perfectly. Our initial radon readings were 8.6pCi/L in our new home. Now they have dropped to only 1.0pCi/L. Can’t do better than that. Hire Chris to test your house. And if you need radon mitigation, he’s the guy!

Chris and the crew at Aristeia Radon are true professionals. If you want it done right the first time, this is the team you need. I highly recommend contacting them for any testing, mitigation or questions about Radon.

When we bought the house, we had a radon test done showing 1.8 pCi/L average, spiking to 3.0 pCi/L. It was below the limit, so we didn't need to address it, but I knew my family would spend a lot of time in the built out basement. Chris was the only company to come onsite to evaluate the job, clearly explained the work to be done and how it would look, and committed to a price beforehand. The work was done exactly as described, in the timeline discussed, for the price committed. He cleaned the space after the work was done. We now have an average of 0.4 pCi/L spiking to 0.9pCi/L. Incredible success. Well worth the peace of mind. Screenshots of tests (independent of Chris) done. White is before, black is after.

So great! Chris knows what he’s doing. They don’t charge until they lower the radon to a safe level. Our radon problem was a challenge but they fixed it quickly. We had to call them out to fix what another company had done. It was relief to find them. Highly recommend!

They got the job done in one day. The whole crew was very professional. They showed up on time, communicated options, and explained the process. Underpromised and over-delivered. They nailed the Radon reduction on the first try.
