Protect Your Home from Radon in Missouri & Northwest Arkansas
Radon is a naturally occurring gas that can build up inside homes across Springfield, Nixa, Branson, and Northwest Arkansas. It has no smell, no color, and no immediate warning signs, but long-term exposure can pose serious health risks.
If you’re concerned about high radon levels in your home, professional radon testing and mitigation can identify the issue and safely reduce levels.
At Smouse Bros, we install reliable radon mitigation systems designed for long-term performance and peace of mind.
What Is Radon Mitigation?
Radon mitigation is the process of reducing radon gas levels inside a home.
This is typically done by installing a system that pulls radon from beneath your foundation and vents it safely outside before it can enter your living space.
Most systems:
Run continuously in the background
Require very little maintenance
Can reduce radon levels within
24–48 hours
Why Radon Matters
Many homeowners assume radon isn’t an issue unless they notice something—but that’s what makes it easy to overlook.
Radon exposure is a long-term health concern that builds over time. According to the EPA, elevated radon levels are the second leading cause of lung cancer behind smoking. In some cases, prolonged exposure to high radon levels can have an impact comparable to smoking up to two packs of cigarettes a day.
That doesn’t mean every home has dangerous levels, but it does highlight why testing is important. Because radon is invisible and odorless, the only way to know your home’s levels is to test.
- It’s completely invisible and odorless
- It can build up indoors over time
- Levels can vary from one home to the next
- Long-term exposure can impact your health
Why Radon Is a Concern in the Ozarks
Homes throughout the Springfield, MO area and Northwest Arkansas often experience higher radon levels due to the natural geology of the Ozarks.
The region is known for its limestone bedrock and fractured soil conditions, which can allow radon gas to move more easily through the ground. These small cracks and gaps in the rock create pathways for radon to travel upward and enter homes through foundations, crawl spaces, and basements.
Because of this, radon levels can vary significantly—even between homes in the same neighborhood.
- Limestone and rock fractures allow gas to move more freely
- Soil conditions can increase how radon travels toward your home
- Basements and crawl spaces create natural entry points
- Nearby homes may have completely different radon levels
This is why radon testing is especially important in the Ozarks. Local conditions make it more likely for elevated levels to be present, even in newer homes.
How Radon Gets Into Your Home
Radon gas rises from the ground and enters through the lowest points of your home.
Common entry points include:
Cracks in basement floors or walls
Crawl spaces and exposed soil
Gaps around pipes and utilities
Sump pump pits
Porous concrete or block walls
If your home already has moisture or foundation issues, those same pathways can allow radon to enter.
Our Radon Testing & Mitigation Process
We take a straightforward, proven approach to identifying and reducing radon levels.
1. Radon Testing
We measure radon levels in your home to determine if mitigation is needed.
2. Home Evaluation
We assess your foundation, crawl space, or basement to identify entry points and system design needs.
3. System Installation
Your radon mitigation system may include:
- Sub-slab depressurization systems
- Crawl space membrane systems (if applicable)
- PVC vent piping
- High-efficiency radon fan
- Sealing of key entry points
4. Post-Installation Testing
We confirm that radon levels have been reduced to safe levels after installation.
What Does a Radon Mitigation System Do?
A radon mitigation system works by creating negative pressure beneath your home.
This pulls radon gas from the soil and redirects it safely outside through a vent pipe before it can enter your home.
Once installed, the system runs continuously to keep levels low over time.
Signs You Should Test for Radon
Radon has no visible symptoms, but testing is strongly recommended if:
You’ve never tested your home
You’re buying or selling a home
Your home has a basement or
crawl space
You’ve noticed moisture or
foundation issues
Nearby homes have reported high
radon levels
Testing is quick, simple, and the only way to know for sure.

Radon Mitigation & Testing — FAQs
What is a safe radon level?
The EPA recommends taking action if radon levels are at or above 4.0 pCi/L. Many homeowners choose to mitigate at lower levels for added peace of mind.
Why is radon more common in the Ozarks?
Radon is more common in the Ozarks because of the region’s limestone bedrock and naturally fractured soil. These conditions allow radon gas to travel more easily through the ground and into homes.
How do I know if my home has radon?
Radon cannot be seen or smelled. The only way to know is through professional radon testing or a home test kit.
How much does radon mitigation cost?
The cost depends on your home’s size, foundation type, and system design. The most accurate way to determine cost is with an in-home evaluation.
How long does radon mitigation take?
Most radon mitigation systems can be installed in one day, with results improving within 24–48 hours.
Do I need a radon system if I’ve never had issues?
Yes. Radon does not cause noticeable symptoms, so testing is recommended even if you haven’t had any known problems.
