Radon Mitigation Repair
Expert Diagnosis & Repair for Underperforming Radon Systems
A radon mitigation system is only effective if it’s working properly. Over time, even well-installed systems can experience performance issues due to equipment failure, improper design, home modifications, or natural wear and tear. When radon levels rise again or system components stop functioning as intended, prompt professional repair is essential.
At Radon Mitigation Corporation, we specialize in radon mitigation repair, diagnostics, and upgrades for homes across Illinois and surrounding communities. As a dedicated radon mitigation provider and part of the Rely Home Solutions family, our team focuses exclusively on identifying system failures and restoring proper radon reduction performance, so your home remains safe.
If your radon system isn’t delivering the protection it should, we can help.
When Do You Need Radon Mitigation Repair?
Many homeowners assume that once a radon system is installed, it will work indefinitely. In reality, radon systems are mechanical and structural systems that require periodic inspection and maintenance.
You may need radon mitigation repair if:
- Radon test results show elevated levels after installation
- The system fan is noisy, vibrating, or not running
- A system alarm or monitor has activated
- You’ve remodeled or altered your home’s foundation or HVAC system
- The system was installed incorrectly or does not meet current standards
- Suction points or piping have become damaged or disconnected
If you’re unsure whether your system is functioning correctly, professional diagnostics are the safest next step.
Comprehensive Radon System Diagnostics
Effective repair begins with proper evaluation. Our technicians take a methodical approach to diagnosing radon system issues, identifying both visible and hidden problems that affect performance.
Our Diagnostic Process Includes:
- Visual inspection of all system components
- Evaluation of fan operation and airflow
- Inspection of piping layout and connections
- Assessment of suction pressure and venting
- Review of foundation sealing and entry points
- Analysis of recent radon test results
This thorough approach allows us to pinpoint the exact cause of system failure rather than applying temporary or ineffective fixes.
Radon Mitigation Repair Services We Provide
Once the issue is identified, we provide targeted repairs designed to restore long-term system performance.
Fan Replacement
Radon fans operate continuously and may fail over time. We replace faulty or inefficient fans with high-quality, energy-efficient models designed for quiet and reliable operation.
Piping Repair & Rerouting
Improperly installed, damaged, or inefficient piping can reduce suction and airflow. We repair, seal, or reroute piping to optimize system performance and comply with best practices.
Correction of Poor Installations
Some systems are installed without proper suction points, sealing, or vent placement. We correct design flaws and bring systems up to professional standards.
Sealing & Caulking Improvements
Cracks, gaps, and foundation penetrations allow radon to bypass the mitigation system. We improve sealing around sump lids, joints, and entry points to support effective radon reduction.
Ventilation Adjustments
Improper vent termination or airflow restrictions can reduce system effectiveness. We adjust ventilation to ensure radon gas is safely discharged above the roofline.
System Upgrades
Older or undersized systems may no longer meet your home’s needs. We upgrade components to improve performance and efficiency.
Radon Mitigation System Inspections
Routine inspections help ensure your system continues to operate as intended and identify issues before radon levels rise.
Why Professional Repair Matters

Frequently Asked Questions (FAQs)
How do I know if my radon system is no longer working?
Rising radon test results, activated alarms, loud fan noise, or lack of airflow are common indicators that your system needs professional inspection.
Can you repair a system installed by another company?
Yes. We regularly diagnose and repair radon systems installed by other contractors.
How long does radon mitigation repair take?
Most repairs can be completed in a few hours, depending on the issue and system complexity.
Will I need to replace my entire radon system?
Not always. Many issues can be resolved through targeted repairs or component upgrades rather than full replacement.
Should radon systems be inspected regularly?
Yes. Periodic inspections help ensure continued performance and early detection of problems.
Do you retest radon levels after repairs?
Yes. Post-repair testing is recommended to confirm the system is effectively reducing radon levels.
