Jason and Mike did a great job with my house in Westlake Village. They brought my radon levels down significantly to levels where I no longer stress about any sort of exposure to myself or my son. They started working immediately on two systems on my house and within two days my meter was at 0.4. Thank you!

We're very happy with the radon mitigation system that Radon California installed on our home in Lake Arrowhead. Our home had been testing at around 15 pCi/L. I visited the house a week later (this is a 2nd home for us) and it's now testing well below 1 pCi/L. I wasn't able to get it that low even keeping all the windows open before!

He was able to install the system within the estimate time, and was right on schedule. No surprises, which is always nice. Highly recommended!

Jason is the best!
He did an outstanding job from start to finish. He took the time to educate us and kept us informed throughout the entire mitigation process. Our radon levels were way up in the 30s, and he got them down to well below 1 pCi/L — incredible results. You can tell he takes real pride in his work and genuinely cares about his customers. Highly recommend!
