If you’ve recently tested your home for radon and discovered elevated levels, you’re probably wondering what happens next. The good news? Radon mitigation systems are highly effective, professionally installed solutions that can reduce dangerous radon levels by up to 99%. But how exactly do they work?
At Certified Radon Systems, we’ve installed over 3,000 radon mitigation systems across Western New York and Pennsylvania since 2007. In this guide, we’ll answer the most common questions homeowners have about how these systems protect your family.

What Is a Radon Mitigation System?
A radon mitigation system is a ventilation setup designed to reduce radon gas concentrations in your home. Radon is a naturally occurring radioactive gas that seeps up from the soil beneath your foundation. Because it’s colorless and odorless, you can’t detect it without testing but long-term exposure is the second leading cause of lung cancer in the United States.
Mitigation systems work by intercepting radon before it enters your living space and safely venting it outside, where it disperses harmlessly into the atmosphere.
How Does the System Actually Remove Radon?
The most common and effective method is called Active Soil Depressurization (ASD). Here’s how it works:
- A suction point is created by drilling a small hole through your basement floor or slab, reaching the soil or gravel beneath.
- A PVC pipe is installed that runs from this suction point, through your home, and exits through the roof or sidewall.
- A radon fan is attached to the pipe, creating negative pressure beneath your foundation. This pulls radon gas from the soil before it can enter your home.
- The gas is vented safely outdoors, where it quickly dilutes in the open air.
This continuous ventilation cycle runs 24/7, ensuring radon levels stay consistently low. The fan is quiet, energy-efficient, and designed to operate for years with minimal maintenance.
Where Is the System Installed in My Home?
Every home is different, and that’s where professional expertise matters. The system components are typically placed in these areas:
- Suction point: Usually in the basement or crawl space, positioned for maximum effectiveness based on your home’s foundation type.
- PVC piping: Routed through closets, garages, or along exterior walls to minimize visual impact.
- Radon fan: Installed in the attic, garage, or on the exterior of your home – never in living spaces.
- Exhaust point: Vented above the roofline or away from windows and doors.

How Long Does Installation Take?
Most residential radon mitigation systems can be installed in 3 to 5 hours. The process includes:
- Assessing your home’s foundation and layout
- Drilling the suction point
- Installing and sealing all piping
- Mounting and wiring the fan
- Testing the system to confirm proper operation
For more complex situations – like homes with multiple foundation types or crawl spaces – installation may take slightly longer. Commercial projects naturally require more time depending on building size and complexity.
Will I Notice the System Running?
One of the most common concerns homeowners have is noise. Modern radon fans are designed to operate quietly, and when properly installed, most people forget the system is even there.
You may notice:
- A low hum from the fan, similar to a bathroom exhaust fan
- A small monitor or indicator showing the system is functioning properly
That’s it. No loud machinery, no disruption to daily life – just continuous protection working in the background.
How Do I Know the System Is Working?
After installation, we recommend retesting your home’s radon levels within 24 to 48 hours to confirm the system is performing correctly. Most systems include a u-tube manometer or digital monitor that provides a visual indication the fan is creating proper suction.
We also recommend:
- Annual radon testing to verify continued effectiveness
- Periodic visual checks of the monitor
- Scheduling maintenance if you notice any changes in fan operation
How Much Does Radon Mitigation Cost?
Costs vary depending on your home’s size, foundation type, and system requirements. However, most residential installations are a straightforward, one-time investment that protects your family for years to come.
