"All Colorado Radon Mitigation Inc did an excellent job! The gentlemen that performed the work took extra care to make sure that the routing of the PVC was done correctly and still achieve the Radon level was going to be below the 4 pCi/L level that EPA requires. They did a very good job with putting the vent in the roof correctly and making sure that no leaks would come from their work. The Radon level that I recorded prior to their work was 15-17 pCi/L and now its down .3-.4. So yes they know what they are doing and they do it very well!"

"This was the 3rd time I’ve used Axium (specifically Tim Krapfl) for home inspection. Tim is very thorough, knowledgeable, and professional! I highly recommend. Tim did the home inspection, but the services also included sewer scope and radon testing."

Radon Detection and Reduction questions, answered by experts

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

No level of radon is technically safe, but since it is present everywhere, complete avoidance is impossible. The average radon level in homes across the United States is 1.3 picocuries per liter (pCi/L). The Environmental Protection Agency (EPA) recommends taking preventative measures if your home's radon levels are between 2 and 4 pCi/L or higher.

Radon is the number one non-smoking cause of lung cancer in the United States, but it can cause some other concerning side effects in the meantime. If you have a raspy voice, chest pains, trouble breathing, difficulty swallowing, or any of the above, don’t hesitate to perform radon testing and install a mitigation system as soon as possible.

Your radon fan needs to operate 24/7 to be effective. The only time the fan isn't operating is during its replacement. Radon levels in the home can increase within hours if the fan stops working or something obstructs the stack vent. Fortunately, radon systems require no downtime maintenance between fan changes.

While DIY testing is possible, abatement generally requires professional installation to ensure efficacy and meet safety standards.
