Radon Inspection Longmont, Boulder, Loveland & the Surrounding Area

Radon Danger

Total Home Inspection Services LLC provides radon testing as an addition to a home inspection, or as a stand-alone service in Loveland & Longmont, CO. We use modern continuous digital radon monitors that are calibrated annually and give you the results immediately upon the conclusion of the testing period (48 hours minimum). The results include not only the average exposure over the testing period but also hourly radon levels within the home. This additional information is extremely useful- I have tested several homes where the average radon exposure is below the EPA threshold, but there are drastic spikes in the levels in the middle of the night when it is likely that the home is occupied.

Radon levels within a home can vary with the season, barometric pressure, and the weather. The EPA recommends testing for radon within the home every two years- to determine if you need a mitigation system, or to confirm the efficacy of an installed system.

What is Radon, and Why Should I Test For It?

  • Radon has no color, odor, or taste and doesn’t cause short-term symptoms of illness.
  • Radon causes cancer.
    • It’s estimated to cause about 21,000 lung cancer deaths per year in the United States.
    • It’s the second leading cause of lung cancer in the United States, according to the surgeon general.
    • Only smoking causes more lung cancer deaths.
  • Radon is a naturally occurring radioactive gas that comes from the breakdown of uranium in the soil.
    • It’s a gas that moves up through the soil to the atmosphere.
  • ​High radon levels have been found in all 50 states and in all parts of Colorado.
  • In Colorado, about half the homes have radon levels higher than the U.S. Environmental Protection Agency recommended action level of 4 picocuries per liter (pCi/L)
  • The most effective solution is usually a sub-slab (or if you have a crawl space, sub-membrane) depressurization system.
  • A mitigation system in Colorado usually costs about $800-$1,200 unless difficult design problems are encountered.
