Fix What Is Not Working Before Levels Rise

Radon mitigation system troubleshooting and repairs in Northeast, WI

A radon system that worked for years can stop performing if piping disconnects, seals fail, or a component wears out. You might notice the fan sounds different, or a recent test showed elevated levels after years of safe readings. Radon Safe Homes and Businesses repairs mitigation systems in Northeast WI by diagnosing the root cause and correcting the failure before radon concentration climbs back into hazardous ranges.

The repair process starts with a visual inspection of all accessible components, including piping runs, seals at the slab, and electrical connections. The technician checks for disconnected joints, cracks in PVC piping, or blockages that reduce airflow. If the system was installed years ago and no longer meets current performance standards, upgrades may be recommended alongside repairs. Both residential and commercial systems are serviced.

Schedule a system inspection today if your radon levels are rising or your equipment is not functioning as it should.

What Gets Fixed During a Repair Visit

When the technician arrives they trace the entire system from the suction point beneath the slab to the exhaust above the roofline. Disconnected piping is the most common issue, especially in systems that run through unfinished basements or crawl spaces where pipes can be bumped or shifted. Leaking joints are resealed with appropriate fittings, and cracked sections of PVC are cut out and replaced.

After repairs are completed, the manometer shows restored pressure difference, confirming the system is pulling air again. You will notice the fan runs steadily without hesitation, and radon levels drop back to the range recorded when the system was first installed. The change is not immediate, but concentration falls within one to two days after airflow is restored.

Older systems sometimes require additional work beyond simple repairs. If the original installation used undersized piping, lacked proper sealing at the slab, or was designed before current EPA guidance, the technician may recommend upgrades that improve long-term reliability. Repairs do not always require replacing the fan, but performance issues are evaluated during every service visit. The goal is to restore function without unnecessary replacement of components that still work.

Common Concerns About System Repairs

Homeowners and property managers often ask what causes systems to fail, how long repairs take, and whether older systems can be brought back to standard. These answers address the practical questions that come up before booking service.

What causes a radon system to stop working?
Disconnected piping, failed seals, fan motor failure, or blockages in the suction pit are the most common causes. Systems in basements or crawl spaces are more prone to accidental damage from storage or remodeling work.
How do I know if my system needs repair or replacement?
Radon Safe Homes and Businesses performs a diagnostic inspection to determine whether individual components can be repaired or if the entire system needs replacement. Most issues can be fixed without starting over.
Can older systems be repaired to meet current standards?
Yes, in many cases. If the original design is sound, repairs and selective upgrades can bring an older system into compliance without full replacement.
How long does a repair visit take?
Simple repairs like resealing joints or reconnecting piping take one to two hours. More involved work, such as replacing damaged piping runs or upgrading components, may take longer depending on system complexity.
Will repairs bring radon levels back down?

Yes, as long as the underlying system design is adequate. Once airflow is restored and leaks are sealed, radon concentration drops back to safe levels within a day or two in Northeast WI homes.

If your manometer is not showing movement or recent testing revealed rising radon levels, Radon Safe Homes and Businesses can inspect your system and make the repairs needed to restore performance. Reach out to schedule a diagnostic visit in Northeast WI.
