I spoke with Vanessa - they were honest, transparent with me which I really appreciate. I had some questions about lead testing and they were straight shooters with me. Definitely recommend them and will use their business in the future.

What Is a Radon Inspection?  

A radon inspection involves placing a measurement device—usually in the lowest livable level of the property—for 2 to 7 days. Once the test is complete, samples are sent to a lab or analyzed on-site using calibrated digital equipment.

If results come back above the EPA action level of 4.0 pCi/L (picocuries per liter), follow-up testing or mitigation may be needed.

Do I Need a Radon Test in Colorado?  

Yes. Radon is naturally occurring throughout Colorado, and levels can vary drastically—even between neighboring homes. Testing is recommended for:

  • Property buyers (residential or commercial)
  • Rental property inspections (Denver’s licensing program)
  • Daycares, schools, or elder care facilities
  • Post-renovation or foundation work
  • Homes with basements or crawlspaces
  • Properties in high-risk zones (EPA Zone 1)

Even if not legally required, a radon inspection is a low-cost, high-impact safety check.

Why Radon Testing Matters

  • Radon exposure is linked to lung cancer and respiratory damage
  • You can’t smell, taste, or see radon—testing is the only way to detect it
  • Children, elderly, and immunocompromised individuals are most at risk
  • Radon levels can fluctuate seasonally or after construction work
  • Results can affect real estate transactions, mortgage underwriting, or tenant compliance  

What Happens if Radon Levels Are High?

If initial testing shows radon levels above 4.0 pCi/L:

  1. We’ll recommend a follow-up test (to confirm results)
  2. If still high, you’ll need a radon mitigation system
  3. We can refer you to licensed radon mitigation contractors
  4. After mitigation, we retest to verify that radon levels are reduced to safe levels

Mitigation systems typically use sub-slab depressurization—a fan system that pulls radon from under the house and vents it outside.  

How EnvioCore Can Help

  • 🔍 Certified radon inspectors using EPA-approved methods
  • 🕒 Short-term and long-term tests (2–7 days or 90+ days)
  • 📄 Clear reports with EPA action levels, results, and next steps
  • 🏠 Single homes, multi-family units, and commercial buildings
  • 🔧 Post-mitigation testing for final clearance
  • 💨 Optional indoor air quality testing (mold, VOCs, particulates)  

How the Process Works

1. Schedule Your Test: We choose strategic test locations (typically basement or first floor).

2. Place the Device: A passive canister or active monitor runs for 2–7 days.

3. Retrieve & Analyze: We collect the sample and send it to an accredited lab (or use digital results).

4. Receive Your Report: You’ll get a written summary of findings with EPA thresholds and recommendations.

Preparing for Your Radon Test  

To ensure accurate results:

  • Avoid opening windows or running fans near test areas
  • Don’t move or disturb the testing device
  • Inform us of any recent foundation work or flooding

Radon Testing FAQs

Is radon really that dangerous?

Yes. It’s the second-leading cause of lung cancer in the U.S. after smoking.

What if I already have a mitigation system?

We recommend testing every 2 years—even with a system in place.

Can I do this myself with a store-bought kit?

You can, but professional testing is faster, more accurate, and often required for real estate or compliance purposes.

Does radon affect newer homes too?

Yes. New homes can still have radon issues—especially those with tight seals and poor ventilation.
