How to DIY Radon Testing (and When to Call a Pro)

Radon is an odorless, colorless gas that can seep into homes from the soil—and it’s the second leading cause of lung cancer in the United States. It’s a serious risk, but fortunately, it’s easy to test for and relatively simple to address.

The good news? You can absolutely test for radon yourself.

Where Radon Comes From

Radon is naturally released from rocks and soil as uranium breaks down. It enters homes through cracks in the foundation, sump pump openings, floor drains, or gaps around pipes. Minnesota—especially Washington County—is known for elevated radon levels due to our geology.

How DIY Radon Testing Works

• Pick up a radon test kit online or at a local hardware store (cost: $10–$25)
• Place the kit in the lowest livable level of your home (usually a basement)
• Leave it undisturbed for the recommended period—usually 2 to 7 days
• Seal the kit and mail it to the lab (included with most kits)
• Get your results—typically within a week

Test kits are most reliable when the home is “closed”—meaning windows are shut and HVAC systems are running normally.

When to Consider a Professional Radon Test

If you’re in the middle of a real estate transaction, time and accuracy matter. That’s where a professional radon test makes more sense:

• We use continuous radon monitors for fast, certified results
• Tests can be completed in as little as 48 hours
• Our devices track hourly radon levels and tampering
• Results are delivered digitally—perfect for negotiating during escrow

What’s Considered a High Radon Level?

The EPA recommends mitigation if your radon levels are 4.0 pCi/L or higher. Even levels between 2.0 and 4.0 may warrant action depending on your home, health risks, and personal comfort level.

If You Get a High Reading

Don’t panic. Radon mitigation systems are effective and relatively affordable (typically $800–$1,500). We’ll help guide you through next steps or refer you to a trusted local mitigation specialist.

Our Bottom Line

DIY testing is a smart, affordable way to check your home. But if you’re under contract or need official documentation, professional testing is worth it.
