What is
radon?

Radon is a naturally occurring radioactive gas that forms when uranium in soil and rock breaks down. You can't see it, smell it, or taste it, but it can seep into your home through foundation cracks, gaps around pipes, and sump pits.

Once inside, it can build up to unhealthy levels, especially in basements and lower floors.

Why test?

Radon is the second leading cause of lung cancer in the U.S. after smoking, and the leading cause among non-smokers. Colorado has some of the highest radon levels in the country, and the only way to know if your home is affected is to test.

Any home can have it, whether it's old or new, with or without a basement. Testing is quick and affordable, and it gives you real answers. If your levels are high, you can take steps to fix it. If they're normal, you can stop wondering.

How it works

1

Book your test

Pick a time online or by phone. We'll send closed-house instructions to follow starting 12 hours before setup.

Day 0
2

We place the monitor

A tech sets a continuous monitor on the lowest livable level, away from drafts, sumps, and exterior walls.

Day 1 · ~20 min
3

48 hours of readings

Keep windows and doors closed except for normal coming and going. The monitor logs radon, temperature, and humidity hourly.

Day 1–3
4

Get your report

We pick up the monitor and email a clear report with your average level, the hourly chart, and what to do next.

Day 3

What your
number means

Radon is measured in picocuries per liter of air (pCi/L). The EPA recommends fixing a home at 4.0 pCi/L or higher, and considering it between 2.0 and 4.0.

0 – 1.9pCi/L

Low

No action needed. Retest every two years or after major renovations.

2.0 – 3.9pCi/L

Moderate

Below the action level, but the EPA suggests considering mitigation. A follow-up test helps confirm.

4.0 +pCi/L

At or above action level

Mitigation is recommended. Most systems cut levels dramatically, and we'll retest to confirm it worked.

FAQ

My neighbor's house tested fine. Do I still need a test?

Yes. Radon levels can differ a lot between houses on the same street because of soil, foundation type, and how each home is built. Testing is the only way to know your home's level.

What are closed-house conditions?

Starting 12 hours before the test and for the full 48 hours, keep windows and exterior doors closed except for normal entry and exit. Don't run whole-house fans or fireplaces. Normal heating and AC are fine.

Where will you put the monitor?

On the lowest level of the home you use or could use as living space, usually the basement. We keep it away from drafts, high humidity, sump pits, and exterior walls for an accurate reading.

How soon will I get results?

Your report is emailed within 24 hours after we pick up the monitor, so about three days from setup.

What if my level is high?

Don't panic. High radon is very fixable. We'll explain your results and point you toward licensed mitigation contractors, then retest after the system is installed to confirm it worked.
