Radon System Repair and Re-Inspection in Iowa
Radon fans wear out and levels can creep back up. We connect you with credentialed Iowa specialists to diagnose, repair, and re-verify an existing system.
Radon system repair covers diagnosing and fixing an existing mitigation system that is no longer performing, whether the fan has failed, the manometer shows a problem, or a recent test came back elevated again. Re-inspection confirms the system is holding the home below the action level.
We connect Iowa homeowners with NRPP-certified, Iowa HHS-credentialed specialists who service existing systems regardless of who originally installed them.
Why Systems Need Repair Over Time
Radon fans run continuously and typically last several years, but they do wear out. A silent fan, a manometer reading that has changed, or a new elevated test result are all signs the system may need attention.
Because Iowa levels are so high to begin with, a failed system can let radon climb back above 4 pCi/L quickly. Periodic re-testing, recommended every two years and after any major home change, catches problems early.
Repairs and Services We Help You Find
Fan replacement
A worn or failed radon fan is replaced with a correctly sized unit for the home’s pressure field.
Manometer diagnosis
The U-tube manometer shows whether the system is pulling suction. A specialist interprets it and finds the cause if it reads zero.
Leak and seal repair
Cracks, failed seals, or disconnected pipe reduce suction. The specialist re-seals entry points and joints.
System redesign
If the original design was undersized, the specialist may add a suction point or upsize the fan.
Re-inspection and re-testing
After repair, a test confirms the home is back below the action level.

Frequently Asked Questions
How long do radon fans last?
Radon fans run continuously and typically last several years before wearing out. A silent fan or a manometer reading that has changed are signs it may need replacement.

A level manometer usually means the system is not pulling suction, often a failed fan or a leak. A credentialed specialist can diagnose the cause.
Can a specialist service a system someone else installed?
Yes. Credentialed specialists repair and re-inspect existing systems regardless of who installed them.
How often should I re-test?
The EPA recommends re-testing every two years and after any major home renovation or change to the system.
