Frequently Asked Questions: Radon Mitigation
What is radon mitigation?
A radon mitigation system is a fan and piping system that prevents radon gas from entering the home by trapping it at its source (beneath the home) and diverting it to the outdoors. For a home with a basement or a slab foundation, the concrete slab serves as the barrier and PVC piping is inserted into the slab. In a home with a crawlspace, a network of perforated drain pipe is installed and a sealed plastic barrier traps the radon gas beneath it. In either case, the system PVC piping is then either routed to the exterior or up into an attic. Exterior mounted fans are vented at the roofline using either PVC or downspout/gutter material; attic mounted fans exhaust through the roof similar to a bathroom vent fan. Radon mitigation fans are designed to be continuously running.
Are radon mitigation systems unattractive?
While a mitigation system can be unattractive-looking, it does not have to be. The cosmetic appeal of any radon mitigation system depends upon the installer’s attention to detail, skill level, knowledge of the subject, and pride in workmanship. The EPA recommends that a radon mitigation system be installed by a certified radon mitigation contractor, since they have been trained to properly and correctly install these systems. However, simply because a mitigator is certified does not mean that he/she will exhibit the same level of attention to detail, skill level, and pride in their work as we do.
What types of mitigation fans are available?
We use two styles of fans: a round-body, in-line style model and a cosmetically appealing box model. In-line fans, such as the RadonAway GP/RP series, can be used in both interior and exterior applications. There are a variety of models in each series, allowing for a wide range of system applications. Our expertise and experience help us select the right fan for a particular installation. Box-style fans, such as the RadonAway SF180, offer a cosmetically appealing upgrade when system aesthetics are important to a client. Box fans sit flush to the siding and look similar to other exterior appliances, making them far less noticeable in high-traffic areas.
What happens if the radon system does not reduce the radon to acceptable levels?
Unlike some other mitigators, if the radon level does not fall below 4.0 pCi/L, we do not shrug our shoulders, say we’ve done all we can, and walk away from the job. We return to determine why the level has not been reduced adequately and take steps to correct it. There is no extra charge, unless extensive additions or modifications need to be done.
