frequently asked questions

How common is radon in Colorado?
Surveys conducted by the Colorado Department of Public Health and Environment indicate that 4 out of 10 Colorado homes have the potential for having radon concentrations in excess of the EPA guidelines. That is why the number of people testing their homes, schools and office buildings is continually increasing. The state of Colorado does have a higher than most potential of increased radon levels.
Why should I test for radon?
Nearly one out of every 15 homes in the United States is estimated to have an elevated radon level (4pCi/L or more). Elevated levels of radon gas have been found in homes in your state. Contact your state radon office for more information about radon in your area. The EPA recommends fixing your home if the results of one long-term test or the average of two short-term tests show radon levels of 4pCi/L or higher. With today?s technology, radon levels in most homes can be reduced to 2 pCi/L or below. You may also want to consider fixing if the level is between 2 and 4 pCi/L.
My home has tested high for radon, now what do I do?
If you have confirmed that your home has elevated radon levels 4 pico curies per liter (pCi/L) or higher you will need to complete the following:

1) Select a qualified radon mitigation contractor to reduce the radon levels in your home
2) Determine an appropriate radon reduction method with your contractor
3) Have the appropriate radon reduction system installed
4) Perform post mitigation testing to verify the radon levels have been effectively reduced
5) Maintain your radon reduction system and inspect the system monitor periodically
