How do you mitigate radon in a slab?
In order to reduce radon in slab homes, one of four types of soil suction methods are employed: subslab suction, drain-tile suction, sump-hole suction, or block-wall suction. Active subslab suction — also called subslab depressurization — is the most common and usually the most reliable radon reduction method.
Does a radon mitigation system run constantly?
Radon system fans are constantly running to ensure that your home stays safe. Due to its constant work, fans may need to be replaced after five years or more, but it is a simple process for an experienced radon contractor.

Are radon mitigation systems noisy?
There are two noises that are generated by the radon system: air flow and vibration. Excessive noise and back pressure is created when too much air is moved through the pipe. According to the best standard, a 3” pipe should move no more than 34 CFM before the system is too noisy and loses efficiency.
