Trusted Radon Repairs in Brewer

We always recommended hiring a certified radon mitigation professional. Incorrect fan selection, improper installation, or inadequate sealing can result in a system that fails to reduce radon levels effectively. A professional will ensure the replacement fan matches the required CFM (cubic feet per minute) and static pressure specifications for your system. They will also perform post-replacement testing to verify the system is operating correctly.

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.

Radon levels typically begin dropping within 24 hours of a repaired or replaced system becoming fully operational. You can conduct a short-term test starting 24 to 48 hours after repair to get an initial indication of performance. Full stabilization of radon levels throughout the home may take several days depending on the home's construction and the severity of prior radon accumulation. A long-term test conducted after repairs will provide the most accurate representation of your annual average exposure.

Moisture and condensation are common in radon mitigation systems because the system is drawing air from beneath the foundation, where humidity levels are high. Most systems are designed with a slight downward slope in the piping to allow condensate to drain back underground. If water is pooling at the fan or dripping excessively, it may indicate a drainage slope issue, a high water table, or a compromised pipe joint. A radon professional can assess and correct drainage issues to prevent moisture damage to the fan.

The manometer is typically a small U-shaped tube filled with colored liquid, mounted on the radon pipe in your basement or utility area. If the fluid levels are unequal - one side higher than the other - the system is actively generating suction and operating correctly. Equal fluid levels on both sides indicate a loss of suction, meaning the fan may have failed. Check your manometer monthly as part of a simple routine home maintenance habit.
