Our Services

Radon Mitigation

The most common method of radon mitigation is called Active Soil Depressurization (ASD) system. An ASD Radon Mitigation System is basically PVC piping attached to an in-line radon fan. The piping typically begins below the lowest floor of the structure’s foundation (basement or crawl space) and extends upward to an exit point above ground level. The radon fan is mounted in an inconspicuous location on the exterior of the home, or in an attic space, or sometimes in the garage. When radon is released into the atmosphere, it is no longer hazardous as it is diluted by the outdoor air. Radon is only lethal when trapped indoors. We are certified by the NRPP (National Radon Proficiency Program) and will thoroughly explain the best method to protect your family.

Radon Testing

The first step to protecting your home, business, school or day-care center from the harmful effects of Radon is to get a test completed right away. We make Radon Testing and Mitigation in the Denver area very easy and affordable and will provide the best tools necessary to get your home tested quickly and accurately. All Phase Radon LLC is certified with the NRPP (National Radon Proficiency Program). We use the Sun Nuclear 1028-XP Continuous Radon Monitor, which is calibrated to standard every year. Our tests indicate the potential for radon levels at the location, providing information for the type of mitigation necessary.


We used All Phase Radon LLC this summer. We have owned our house for 15 years, but didn’t realize we needed to test it every couple of years. Ryan was super informative and really walked us through the process and why it was important. After working with him, I felt much more knowledgeable, not to mention safe and radon free!! He was professional, punctual, and precise. He got the work done quickly and efficiently. I would highly recommend using All Phase Radon LLC to get your house tested and mitigated!! – Jamie Barilla
