"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

Radon is present almost everywhere but, like sunlight, the concentration levels and how often you are exposed to it have a large part to play in just how dangerous it is. There are levels of radon that are acceptable inside a house, but above a certain limit, radon becomes a serious radioactive hazard that is a known cause of lung cancer. In fact, radon exposure is the number two leading cause of lung cancer (after smoking).

Long-term exposure increases lung cancer risks. Prolonged homestay individuals and smokers encounter heightened vulnerability and exposure concerns.

No, radon mitigation systems do not decrease home value or make a home harder to sell. In areas where homes experience similar radon exposure risks, a radon mitigation system is viewed as an improvement. Potential homebuyers often opt to buy a home with a radon mitigation system already installed to reduce the risk of cancer for their families.

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.

Installation typically takes 1-2 days, depending on the system and property layout.
