Google reviewers rate Affordable Radon Services 4.9 out of 5 based on 705 reviews, with the owner responding to 43 percent of them. Customers frequently highlight clear communication, competitive pricing, and the ability to solve complex installation issues in difficult properties.

We just had Affordable Radon install a mitigation system in our middle-unit townhouse and I can’t recommend them enough. Our situation wasn’t typical. With neighbors on both sides, running the pipe up the outside wasn’t an option, so the system had to be routed internally. Jesse came out, looked at the space, and…

Loved the flexibility, expertise and courtesy extended to us during the radon testing process.
We just had Affordable Radon install a mitigation system in our middle-unit townhouse and I can’t recommend them enough. Our situation wasn’t typical. With neighbors on both sides, running the pipe up the outside wasn’t an option, so the system had to be routed internally. Jesse came out, looked at the space, and proposed a solution that made sense right away. He explained the options clearly and put me at ease about a project I’d been unsure about.
From start to finish the team was responsive, informative, and on time. They stayed on top of every detail and made the whole process easy. Beyond doing great work, they’re just great people to work with. If you have a tricky layout or think radon mitigation won’t work for your home, call Affordable Radon. They’ll find a way.

Affordable Radon Services staff members Aaron and Ben did an amazing job with installing and explaining the process of our new system. The price for the radon system was comparable to other companies in the area but the customer service and attention to detail was more than just another job for them. Both Aaron and Ben took their time and explained the process step by step making the decision to move forward with their business an easy one for us. I highly recommend them for their business!

Excellent work. The owner came out to make a plan for where to put our radon system on our oddly-shaped duplex and figured out how to do it when two other companies couldn’t figure it out without making it look horrible. The tech on the day of install figured out an even better way to do it, and worked well with the electrician who wired the outlet. And all for half the price I was quoted elsewhere. Highly recommend.

Could not be more thrilled with their quality of work and professionalism.
Update!
7 years later our system is running fine! We had an anomalous flood event in the basement that peeled our vapor shield off. Within 2 days of calling their office we had Aaron out to take a look and give us a quote. The quote was better than reasonable with a great explanation of what will be done and how their process has improved. I gotta say that, as a skilled tradesman, I wish that most other trades I dealt with put up the quality of work and timeliness that Affordable displays.
