Radon System Maintenance & Repair in Columbus Ohio

Why Radon System Maintenance Matters

Your radon mitigation system is the primary defense protecting your family from dangerous radon gas exposure. Like any mechanical system in your home, it requires regular maintenance to continue operating at peak performance. A radon mitigation system that is not properly maintained can lose efficiency over time, allowing radon levels to creep back up to unsafe concentrations without you even knowing it.

In Columbus, Ohio and the surrounding Franklin County area, homes are particularly susceptible to elevated radon levels due to the region's geology. The limestone and shale bedrock common throughout central Ohio creates pathways for radon gas to migrate from the soil into your home's foundation. This makes ongoing system maintenance not just recommended but essential for every homeowner with a mitigation system installed.

The EPA recommends retesting your home for radon every two years, even with an active mitigation system in place. Regular professional inspections between those tests help ensure your system stays effective year-round, catching potential issues before they compromise your family's safety.

Our Comprehensive Annual Inspection Service

Our annual maintenance inspection is a thorough, multi-point evaluation of your entire radon mitigation system. Our experienced technicians follow industry best practices to assess every component of your system, from the sub-slab suction point to the exhaust pipe above your roofline.

Fan Motor Inspection and Testing

The radon fan is the heart of your mitigation system, running continuously 24 hours a day, 365 days a year. Over time, fan motors experience normal wear that can reduce airflow and suction capacity. During our inspection, we test the fan's electrical draw, listen for bearing noise or vibration issues, and measure the actual suction being produced. Most radon fans have a lifespan of 5 to 10 years, and identifying a declining fan early allows you to schedule a replacement at your convenience rather than dealing with an emergency failure.

Seal and Connection Checks

The seals around your suction point, sump pit cover, and pipe connections are critical to maintaining proper system pressure. Cracks, gaps, or deteriorating caulk can allow conditioned air to be pulled into the system instead of soil gas, dramatically reducing your system's ability to draw radon from beneath the foundation. We inspect every seal point and repair or replace any that have degraded.

Manometer Monitoring and Calibration

Your system's manometer, also called a U-tube gauge, provides a visual indicator that your fan is creating suction. During our inspection, we verify that the manometer is reading correctly, that the fluid level is appropriate, and that the readings fall within the expected range for your specific system design. We also teach homeowners how to check this gauge monthly as a simple self-monitoring step between professional visits.

System Efficiency Testing

Beyond visual inspections, we perform diagnostic tests to measure the actual performance of your system. This includes pressure field extension testing to confirm that adequate suction is reaching all areas beneath your foundation, airflow measurements at the exhaust point, and a short-term radon measurement to verify that the system is maintaining safe indoor radon levels. If we detect any performance issues, we provide detailed recommendations for corrective action.

Exterior Exhaust Point Inspection

The exhaust point where your radon system vents above the roofline is exposed to weather, debris, and potential damage from ice, wind, and animals. We inspect the exhaust pipe for blockages, verify proper termination height and location relative to windows and vents, and check for any signs of moisture intrusion that could affect system components.

Radon Fan Replacement Services

When your radon fan reaches the end of its service life, prompt replacement is critical. A failed fan means your mitigation system is no longer actively removing radon from beneath your home, and radon levels can return to pre-mitigation concentrations within hours.

Fan replacements typically cost between $300 and $500, depending on the fan model and accessibility of the installation. We carry the most common fan models and can often complete a replacement the same day you call. For maintenance plan members, we offer priority scheduling and discounted parts pricing to minimize both the wait time and the cost.

Signs that your radon fan may need replacement include unusual noise such as grinding or humming, manometer readings showing reduced or no suction, the fan motor feeling excessively hot to the touch, or elevated radon test results despite a system that appears to be running. If you notice any of these warning signs, contact us promptly for an evaluation.

Annual Maintenance Plans

Our annual maintenance plan is the easiest and most cost-effective way to keep your radon system in top condition. For just $99 per year, your plan includes:

• One comprehensive annual system inspection
• Manometer verification and fan operation check
• Complete seal and connection assessment
• Written system performance report
• Priority scheduling for repairs (plan members are served first)
• Discounted rates on replacement parts and additional service calls
• Annual reminder notifications so you never miss an inspection

Plan members also benefit from peace of mind knowing that if a problem arises between scheduled inspections, they receive priority service. We understand that a non-functioning radon system is an urgent matter, and we treat our maintenance plan members accordingly.

Common Radon System Issues We Repair

Over years of servicing radon mitigation systems throughout the Columbus metropolitan area, we have encountered and resolved virtually every type of system issue. Some of the most common problems we diagnose and repair include:

• Failed or failing fan motors resulting in reduced suction or complete system shutdown
• Cracked or deteriorated pipe seals that allow air infiltration and reduce system efficiency
• Condensation buildup in the piping system that can impede airflow or cause freezing in winter months
• Foundation cracks that have developed since the original system installation, creating new radon entry points
• Sump pit seal failures that compromise the sealed sub-slab depressurization system
• Electrical issues including tripped breakers, damaged wiring, or faulty connections

No matter what issue your system is experiencing, our technicians have the experience and equipment to diagnose it quickly and implement an effective repair. We carry common replacement parts on our service vehicles to minimize the need for follow-up visits.
