Efficient Radon Repairs Auburn

After a repair, you should receive a written service report detailing the work performed, parts replaced, and any observations made by the technician. You should also receive documentation of any post-repair radon test results conducted by the contractor. If a new fan was installed, retain the warranty card, serial number, and installation date for future reference. Keep all radon-related records in a safe place, as they may be requested by buyers during a future home sale.

Some noise from a radon mitigation fan is normal, as it is essentially a small inline exhaust motor running continuously. However, loud rattling, grinding, or squealing noises are warning signs that the motor bearings are failing and replacement may be imminent. Vibration noise can sometimes be reduced by tightening pipe connections or adding pipe hangers, but internal motor noise typically indicates the end of the fan’s lifespan. Contact a certified radon professional if your system develops any unusual or worsening noises.

Most radon mitigation systems have a visual indicator, called a manometer or U-tube gauge, that shows whether the system is actively creating suction. If the liquid levels in the U-tube are uneven, the system is functioning; if they are even, it may have stopped working. You should also listen for the hum of the fan motor running, which is typically a low, steady sound. The most reliable way to confirm effectiveness is to conduct a radon test at least every two years or after any system repair.

A professional radon system inspection typically includes a visual assessment of all system components, including the fan, PVC piping, pipe joints, sealing around suction points, and the manometer indicator. The contractor will also measure suction pressure at diagnostic ports to confirm the fan is generating adequate airflow. Any cracks, unsealed penetrations, or drainage issues will be identified and documented. The inspection report should include findings, recommended repairs, and whether a radon test is advisable.

A finished basement can make radon mitigation more complex because the concrete slab may be covered with flooring materials that limit access to suction points. If the mitigation system was installed before finishing, this is generally not an issue as long as the existing suction points remain accessible. Renovations that seal or cover existing suction point locations may reduce system effectiveness and require relocation of piping. Always inform a radon contractor about any basement finishing plans before and after installation.
