How Does a Radon Mitigation System Work?
The most common radon reduction method for homes with concrete slab foundations is active sub-slab depressurization.
A professionally installed radon mitigation system uses a specialized fan to create suction beneath the foundation. This helps prevent radon-containing soil gas from entering the home by directing it through sealed piping and exhausting it safely outdoors.
Every home is different. The number of collection points, fan selection, and piping configuration depend on the foundation, soil conditions, and pressure characteristics beneath the slab.
Custom Radon Mitigation for Different Foundations
Not every home can be treated effectively with the same system design.
Depending on the property, Alfa Air Agency may recommend:
- Single-Point Sub-Slab Depressurization: For foundations where one suction point provides adequate pressure-field extension.
- Multiple Collection Points: For larger slabs or foundations where suction does not communicate effectively across the entire area.
- Crawlspace Radon Solutions: Specialized approaches for properties with crawlspaces.
- Custom Fan Selection: Choosing appropriate radon fan performance based on the system’s airflow and static pressure requirements.
Our objective is to design a radon reduction system suited to your property’s actual conditions.
Our Radon Mitigation Installation Process
1. Review Your Radon Test Results
We begin by reviewing your radon measurements and discussing your property’s construction, foundation type, and layout.
2. Design Your Radon Reduction System
We determine the appropriate suction locations, piping route, fan requirements, and other installation details.
Some homes require only one collection point. Others benefit from multiple collection points to achieve effective suction beneath the foundation.
3. Install the Mitigation System
Our installation team creates the required collection point or points, installs the piping and specialized radon fan, and routes the exhaust outside the building in accordance with applicable requirements.
4. Verify Radon Reduction
Post-mitigation radon testing is available to evaluate the system’s performance and confirm the measured radon concentration after installation.
5. Warranty and Ongoing Support
We explain system operation, maintenance considerations, and applicable warranty coverage, including the fan manufacturer’s five-year warranty and the terms of our transferable system warranty.

Frequently Asked Questions
What radon level requires mitigation?
The EPA recommends taking action to reduce radon when a home’s radon level is 4.0 pCi/L or higher. The EPA also advises considering mitigation for levels between 2.0 and 4.0 pCi/L because no level of radon exposure is considered completely risk-free.
How much does radon mitigation cost in Maryland?
Radon mitigation costs depend on your home’s foundation, the number of collection points required, piping configuration, and system design.
Contact Alfa Air Agency for a property-specific estimate.
Will one suction point be enough for my home?
Not always. Some foundations have good communication beneath the slab and can be treated with one suction point. Others require multiple collection points for effective radon reduction.
Does a radon mitigation system need maintenance?
Yes. Homeowners should periodically check the system’s operating indicator and arrange radon retesting according to applicable recommendations. Radon fans may eventually require replacement.
Can I sell my home with a radon mitigation system?
Yes. A professionally installed and functioning radon mitigation system can remain in place when the home is sold. Alfa Air Agency offers transferable warranty coverage, subject to the written warranty terms.
Does Alfa Air Agency provide post-mitigation testing?
Yes. We offer professional post-mitigation radon testing to evaluate the effectiveness of the installed system.
