"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."

"Radon exhaust fan was making noise. I did some research and ascertained bearings were failing in the fan. I arranged a good time to get it replaced, he showed up and had it replaced in about 20 minutes. I did give him the model number of the fan so he knew for sure what I needed. Quick and easy."

"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."

Radon Detection and Reduction questions, answered by experts

Installing a mitigation system reduces radon levels, which can cause lung cancer, providing peace of mind and long-term health benefits. It can also increase your home’s value, as many buyers prefer properties with radon safety measures in place. The investment is relatively low compared to the potential health risks associated with prolonged radon exposure.

The cost for a radon mitigation system typically ranges from $800 to $1,500, with an average around $1,000. The final price depends on several factors, including the size of your home, the severity of the radon issue, and the type of system required. Your home's foundation type also significantly impacts the cost. For example, sealing and ventilating an unfinished basement might cost around $4,600, while encapsulating a crawl space without a foundation slab can range from $1,500 to $15,000.

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.

Keeping radon from getting into your home is much better than having to get rid of it once it's already indoors. While there may not be a way to fully prevent radon from getting into your home, there are things you can do to reduce the gas's ability to enter. 

Sealing foundation cracks and openings can help keep the gas from seeping inside. Improving air flow, such as by opening windows, can also be helpful. If you're building your home from scratch, talk to your contractor about using radon-resistant construction to keep the gas out.

Mitigation can take several days depending on home setup, equipment accessibility, and achieving effective diffusion system sealed efficiency.
