Radon Is Dangerous — But It Can Be Fixed
Radon is a radioactive gas that seeps into your home from the soil. It’s invisible, odorless, and has been linked to thousands of lung cancer deaths annually, according to the EPA.
If you’ve received a radon test result showing levels above 4.0 picocuries per liter (pCi/L), the next step is mitigation — reducing those levels to protect your family and property.
Here’s how to mitigate radon safely and effectively in 2025.
What Radon Mitigation Actually Involves
Mitigation isn’t just sealing cracks — it’s about controlling airflow and gas pressure. The most common system used in homes is called:
🔧 Sub-Slab Depressurization (SSD)
A PVC pipe is inserted below your home’s foundation and connected to a radon fan. This draws radon gas from beneath the slab and vents it safely above the roofline.
Other methods may include:
- Crawlspace depressurization
- Drain tile suction
- Sub-membrane systems (for dirt floors)
DIY vs Professional Installation
Can you mitigate radon yourself? Technically yes — but it comes with serious risks.
⚠️ DIY Risks:
- Improper fan selection or placement
- Incorrect sealing of slab cracks
- No post-install testing
- Safety hazards from working with electricity or drilling through foundations
The EPA strongly recommends using a certified radon mitigation professional to ensure the system meets performance and code requirements.
How Professionals Handle Radon Mitigation
- Assessment — Review your home’s layout and soil pressure zones.
- Installation — Place suction points, seal cracks, and connect the system.
- Fan Setup — A radon-specific fan is installed outside or in the attic.
- System Testing — A post-mitigation radon test is performed 24–48 hours after installation.
🛠️ Typical install time: 4–8 hours
📉 Expected results: Radon levels reduced by 50–99%
How Much Does Radon Mitigation Cost?
On average, radon mitigation systems in 2025 range from $1,000 to $2,500 depending on:
- Foundation type
- Fan power
- Location
- Number of suction points
