So your radon test came back high—and now you’re staring at the word “mitigation” and wondering what’s next.
What exactly does a radon mitigation system do?
How much is this going to cost?
This guide will explain everything in plain English, so you know what to expect and how to make the best decision for your home.
First, What Is a Radon Mitigation System?
A radon mitigation system is designed to safely remove radon gas from your home before it can build up to dangerous levels indoors.
It doesn’t just mask the problem—it redirects the gas from beneath your home and vents it outside, where it can’t harm you.
How Does It Work?
The most common system is called a Sub-Slab Depressurization System. It works like this:
- A small hole is drilled through the concrete slab or basement floor.
- A PVC pipe is inserted into that hole to create a suction point.
- A quiet fan is installed (usually outside or in an attic) to pull radon gas from beneath the house.
- The pipe vents the gas safely above the roofline.
If your home has a crawl space, the process may involve sealing the floor with a vapor barrier and venting from underneath.
What Does Installation Involve?
- Usually takes one day
- Requires access to the lowest level of the home
- Professional systems are designed to be discreet and quiet
- Includes a manometer (pressure gauge) so you can check if it’s working
And don’t worry—this isn’t the kind of job that tears up your home. A certified installer like EnviroPro 360 can do it with minimal disruption.
How Much Does Radon Mitigation Cost?
In Georgia and South Carolina, most homeowners can expect to pay:
$800 – $1,500 for standard installations
$1,500 – $2,500+ for larger homes, difficult layouts, or additional work (like crawlspace sealing)
What affects the price?
- Size and layout of your home
- Foundation type (slab, basement, or crawl space)
- Number of suction points needed
- Whether sealing or additional ventilation is required
- Placement of the fan and piping for aesthetic reasons
What’s Included in the Cost?
When you hire a certified radon contractor like EnviroPro 360, your installation typically includes:
- Full inspection and radon system design
- All materials, piping, and fan installation
- Post-installation testing to confirm effectiveness
- Warranty on labor and equipment
- Ongoing support if levels rise again
Avoid companies that give you a super-low quote but charge extra for “essentials” like the fan, sealing, or post-test.
Can I Install a System Myself?
Technically yes—but not recommended.
DIY systems can miss key airflow dynamics or even make radon worse. Improper venting can also violate building codes or pose safety risks.
A certified radon pro ensures:
- Correct pressure balance
- Proper vent height and direction
- Quiet operation
- Reliable long-term results
And in many home sales or rentals, only certified installations are recognized in legal disclosures.
How Long Does a Radon Mitigation System Last?
- Fans typically last 5–10 years
- PVC pipes can last 20+ years
- With proper maintenance, your system should work for decades
Most systems are nearly maintenance-free—just check the manometer to ensure the fan is working and retest every 2 years.
Radon Mitigation Is Peace of Mind
Radon mitigation isn’t just a safety upgrade—it’s an investment in your home and your health.
It makes your home safer for your family, and it can even boost buyer confidence if you ever sell.
