Devin McDowell, Clear Radon Testing & Mitigation

08/25/2026

It’s been a busy summer at Clear Radon!

Over the past few months, our team has been on the road serving homeowners and commercial clients across Arkansas, Missouri, Oklahoma, and beyond, from straightforward residential systems to large multi-family projects and more complex mitigation challenges.

We’re incredibly thankful for every homeowner, property manager, and business that trusted us with their property this summer.

As we head into fall and spend more time indoors, it’s a great time to think about the air inside your home. If you’ve never tested for radon, or it’s been over 2 years, fall is a great time to put it on your list.

Here’s to a great summer behind us and a busy fall ahead!

What does our radon mitigation guarantee actually mean?

It means we don’t just install a system and hope for the best. We keep working until your radon levels are below the EPA-recommended action level.

At a recent home, our initial mitigation system was successfully reducing radon beneath the basement, but follow-up testing showed occasional spikes. Instead of calling the job finished, we went back to investigate.

Further diagnostics showed that the radon wasn’t coming from beneath the basement anymore. The home also had separate slabs beneath the garage and front porch, and each isolated foundation can be another potential entry point for radon. Testing in the garage showed readings as high as 11 pCi/L.

We expanded the mitigation system to address both the garage and front porch slabs, carefully balancing airflow throughout the system.

That’s what our guarantee means: if the first solution doesn’t get the whole home where it needs to be, we keep diagnosing, adjusting, and working until it does.

Radon mitigation isn’t always one-size-fits-all, and neither is our approach.

Another certified, quality radon mitigation in the books. For this one, we traveled to Willard, MO!

Let us know if the radon levels are elevated in your home, and we can talk about our radon mitigation guarantee.

What is an underslab radon mitigation system?

Our installation in Siloam Springs, AR is a perfect example. An underslab, or passive, radon system is installed before the concrete slab is poured, with piping placed beneath the foundation to create a pathway for radon gas to safely exit the home. Building it into the home during construction keeps the system discreet and makes future radon mitigation much easier. If testing later shows elevated radon levels, a fan can be added to convert the passive system into an active radon mitigation system.

Based in Northwest Arkansas while serving Missouri!

Our company is headquartered in Bentonville, AR, but we regularly travel across state lines in Missouri to provide radon testing and mitigation services. In fact, our founder and owner, Devin McDowell, was born and raised in Nixa, MO, and we love getting back to serve our home state. Here is last week's radon mitigation installation in West Plains, MO!

Most people know us for helping homeowners, but did you know we also design and install radon mitigation systems for large commercial and multi-family buildings?

We thought it'd be fun to share a behind-the-scenes look at one of our larger commercial projects and how we approached it.

If you're curious, we've put together a case study that walks through the project from start to finish:
