Radon Mitigation FAQ — Anchorage, AK

Radon is a naturally occurring radioactive gas that comes from the breakdown of uranium in soil and rock. It's invisible and odorless and can build up indoors. The EPA and U.S. Surgeon General identify radon as a leading cause of lung cancer, which is why testing and, where needed, mitigation are recommended.

The EPA recommends taking action to lower radon at 4.0 pCi/L or above, and considering action between 2.0 and 4.0 pCi/L. No level is considered completely risk-free, but 4.0 is the standard action point. A test of your own home is the only way to know your number.

With a short-term test (days) or a longer-term test (more than 90 days) placed in the lowest lived-in level of the home, following standard placement and closed-house conditions. Longer tests give a better picture of your year-round average. See our radon testing page.

The most common fix is active soil depressurization: a sealed vent pipe and a continuously running inline fan draw radon-laden soil gas from beneath the slab (or a crawl-space membrane) and discharge it outside above the roofline, before it can enter your living space.

It depends on your foundation type, where the system can be routed, and whether you have a basement, slab, or crawl space. The quickest way to a real number is a free quote — tell us your radon level and home type.

A properly designed and installed system typically reduces indoor radon substantially, but the only proof is a follow-up test. That's why post-mitigation retesting is part of the job — you get a measured result, not just a guarantee on paper.
