In past decades, uranium mill tailings from local processing were used as fill in some Grand Junction construction, which led to a federal cleanup program. That cleanup was a separate issue from the natural radon in soil, which affects homes throughout the valley today.
Homes in Grand Junction, Fruita and Palisade include many slab-on-grade and crawlspace houses as well as basement homes. Slab homes often need the pipe routed outside or through the garage, which adds cost.
There are fewer certified radon contractors on the Western Slope than on the Front Range, so it is worth asking whether a travel fee applies and how soon a contractor can schedule a follow-up test.
Yes. Natural radon from soil and rock affects homes across the Western Slope. Every home should be tested, whatever its age or location.
A federal program removed tailings from properties where they were found decades ago. Natural soil radon is a separate, ongoing issue, so homes should still be tested.
Most homes cost $1,200 to $2,200. Slab-on-grade homes and crawlspaces add cost, and some contractors charge travel fees for outlying areas.
Colorado requires radon mitigation professionals to be licensed by the Department of Regulatory Agencies (DORA). Ask for the Colorado license number, look for NRPP or NRSB certification, get a written quote that includes a post-mitigation test, and ask about the fan warranty.
