How Radon Mitigation Systems Work
Radon mitigation systems use active soil depressurization to prevent radon from entering your home. By creating negative pressure beneath your foundation, radon gas is safely vented above your roofline before it can accumulate indoors.
Proven Results
A properly installed radon mitigation system can significantly reduce radon levels in your home.
Types of Radon Mitigation Systems
Sub-Slab Depressurization
The most common and effective system for homes with basements or slab foundations. A pipe extends through the floor into the gravel bed beneath, and a fan draws radon-laden air from under the foundation and vents it safely above the roofline.
Sub-Membrane Depressurization
Designed for crawl spaces. A heavy-duty polyethylene membrane is sealed over the dirt floor, and a fan system draws radon from beneath the membrane and vents it outside.
Block Wall Suction
Used in homes with hollow block foundation walls. Suction is applied to the interior of the block wall to remove radon before it enters living spaces.
Drain Tile Suction
If your home has a drain tile system around the foundation, we can connect to it to depressurize the soil and reduce radon entry points.
Mitigation System Comparison
| System Type | Foundation | Typical Cost | Installation |
|---|---|---|---|
| Sub-Slab Depressurization | Basement, Slab | $1,000 - $1,800 | 1 day |
| Sub-Membrane Depressurization | Crawl Space | $1,000 - $2,200 | 1 day |
| Block Wall Suction | Hollow Block | $1,200 - $2,000 | 1 day |
| Drain Tile Suction | With Drain Tiles | $1,000 - $1,600 | 1 day |
| Combination System | Mixed Foundations | $1,500 - $2,500 | 1-2 days |

Frequently Asked Questions
How does a radon mitigation system work?
Most systems use active soil depressurization. A fan creates negative pressure beneath your foundation, drawing radon-laden air through a pipe and venting it safely above your roofline. This prevents radon from entering your home.
How much does a radon mitigation system cost in Atlanta?
Most residential systems cost $1,000-2,500 depending on home size, foundation type, and system complexity. Contact us for a detailed quote.
How long does installation take?
Most residential installations are completed in a single day.
Will the system be visible?
We work to minimize visual impact. Interior pipes can often run through closets or utility areas. Exterior installations can be painted to match your home. The fan is typically located in the attic, garage, or exterior.
How much electricity does the system use?
Most radon fans use 50-100 watts, similar to a light bulb. Annual operating cost is typically $50-100 in electricity.
What maintenance does the system require?
Radon systems are low-maintenance. Check the manometer monthly to ensure the fan is running. Retesting every 2 years is recommended to verify continued effectiveness.

Radon in Slab-on-Grade Homes: Why No Basement Does Not Mean No Radon
Slab-on-grade homes have no basement, which leads many metro Atlanta homeowners to assume they are safe from radon. They are not. Radon enters through slab cracks, control joints, and plumbing and utility penetrations directly into the living space. How radon gets into a slab home, why these homes still test high, how testing works, and how sub-slab depressurization mitigates a slab home.
