Radon Testing
Know your number first. Then decide.
Every radon decision starts with a test. Because Boulder County is EPA Zone 1, the EPA and the City of Longmont both recommend testing every home, including homes that already have a radon fan.
There are a few ways to test in Longmont. The city points residents to free options: a radon detector you can borrow from the Longmont Public Library, a free mail-in kit from the State of Colorado, or a free Longmont Sustainable Home appointment that includes a kit. Boulder County also lists the CSU Extension office at 9595 Nelson Road in Longmont as a place to buy short-term kits.
If you'd rather have it done for you, or you need a result you can rely on for a decision, we place and read the test and walk you through what it means. Call (720) 790-3231.
Each test answers a slightly different question.
Run 2 to 7 days with the house closed up. Fast, cheap and the usual first step.
Run 90 days or more and give a better picture of your year-round average.
Log hourly readings, which helps when a result needs to be trusted for a decision, like a home sale.
Taken after a system is installed to document that the new level is down.
Testing with doors and windows closed shows the worst case, which is the number that matters.
We explain what your number means and whether the EPA guidance says to fix it.

The test goes in the lowest lived-in level of the home, away from drafts and outside walls.
Keep doors and windows closed except for normal coming and going.
Results are reported in pCi/L. The EPA says fix at 4.0 or higher and consider fixing between 2 and 4.
If the level is high, we design a system and give you a written price.
