"Gage helped me work out a creative solution for my small space to keep the radon pipe out of the way, which other contractors couldn't do. He was also incredibly helpful and flexible with his schedule, which I really appreciated when my HOA took a bit of time to get back to me with approval. The finished job looks professional and clean. Jesse, who did most of the installation, worked hard at my house for the entire day, even out in the hot sun. He is clearly very diligent and did an excellent job. I couldn't be more pleased. Additionally, for the complexity of the job at my house, the price I paid was more than fair. As a side note, both Jesse and Gage are super nice guys, and it feels great to work with a local small business rather than one of the larger radon companies who don't seem to care as much about their work. If you live in the Denver Metro or Front Range area, I highly recommend Custom Radon Mitigations Solutions."

"Jason was very helpful explaining the testing process, and possible mitigation if our Radon levels were high. Radon testing was setup and conduced quickly and our levels were in acceptable ranges, so no mitigation was required."

"I recently used #1 Radon to fix my existing radon mitigation system. I called and Jesse Fuller came to look at system same-day. He had it repaired the same week. He was professional and made me feel comfortable with work and costs to replace the existing fan. I highly recommend #1 Radon and Jesse Fuller."

"All Colorado Radon tackled a particularly difficult radon mitigation that other companies refused to mitigate. They were very thorough and knowledgeable. Most of all, they were successful in reducing radon levels to well below government standards. We would use them again."

"I couldn't be more pleased with the radon mitigation service John provided. The estimate was accurate-no surprises. He was prompt, efficient and quick- it took just over 2 hours and that's including answering all my questions (and I had a lot of questions!). John's customer service was excellent and the results have so far exceeded my expectations. I am very glad I chose RMR."

Radon Detection and Reduction questions, answered by experts

Radon enters your home when warm air begins to rise and exits through the roof, creating a vacuum that pulls cooler air from under the foundation. Part of that air is radon, which is an invisible, odorless gas that develops naturally when radioactive particles are deep within the ground. Those particles usually come from decaying matter in soil and rocks.

Your radon mitigation system may be loud because it’s time to replace it. Any sounds are usually from the inline fan that helps create the vacuum and resulting airflow. If you hear a new, loud mechanical or humming noise from your radon fan, it might be time to replace it. Most fans used in radon mitigation systems last up to 10 years, but may need to be replaced sooner.

Mitigation reduces radon levels, protecting your health and complying with safety standards.

If your home has a sump pit, you can integrate it with a radon mitigation system. You can accomplish this by sealing the pump cover with an airtight lid that accommodates radon vent pipes and sump pump hoses. This allows the vent pipe to redirect the radon gas outside of your home.

The soil beneath your house is most likely what’s causing an increased level of radon. This is because soil holds radioactivity for a long time and it’s also what most buildings are built on. Another common source of radon is water from a source that hasn’t been through periodic radon tests, such as well water. Over time, the radon from the soil can inhabit other parts of your house like the foundation or plumbing.
