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.

Ideal for: Basements, slab-on-grade foundations

Effectiveness: High effectiveness

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.

Ideal for: Crawl spaces, dirt floors

Effectiveness: High effectiveness

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.

Ideal for: Hollow block foundations

Effectiveness: High effectiveness

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.

Ideal for: Homes with existing drain tiles

Effectiveness: High effectiveness

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.
