DIY vs. Professional Radon Testing: Making the Right Choice for Your Colorado Home

Radon is an invisible threat that many homeowners in Colorado aren’t even aware of—yet it's responsible for an estimated 21,000 lung cancer deaths each year in the U.S. alone. With the state’s unique geology, radon is a common concern across Colorado, making regular testing a crucial part of maintaining a healthy home.

But when it comes time to test for radon, many homeowners face a common question: should I do it myself, or hire a professional? Let’s break down the pros and cons of each option to help you make the right choice for your home and family.

Understanding Radon and Its Risks

Radon is a naturally occurring radioactive gas that forms from the breakdown of uranium in soil, rock, and groundwater. It can seep into homes through cracks in the foundation, crawlspaces, or gaps around pipes and drains. Once inside, it can build up to dangerous levels—especially in airtight homes or during colder months when windows and doors remain closed.

Long-term exposure to elevated radon levels is the second leading cause of lung cancer in the United States, second only to smoking. Since radon is odorless, tasteless, and invisible, testing is the only way to know if your home is affected.

What Is DIY Radon Testing?

DIY radon test kits are widely available online and at home improvement stores. These kits come in two main forms:

• Short-term tests (2 to 90 days): Provide a quick snapshot of radon levels.

• Long-term tests (90+ days): Offer a more accurate reflection of average exposure over time.

Most kits involve placing a detector in the lowest livable area of your home, following enclosed instructions, and then mailing the sample to a lab for results.

Pros of DIY Testing:

• Affordable: Most kits cost between $10 and $40.

• Convenient: You can test on your own time without scheduling appointments.

• Good for screening: Helpful as a first step if you’ve never tested your home before.

Cons of DIY Testing:

• Room for error: Placement mistakes or failure to maintain closed-house conditions can affect results.

• Lack of expert interpretation: You may not know what steps to take next if results show elevated levels.

• Limited precision: DIY kits don’t provide continuous monitoring or detailed insights.

Why Choose Professional Radon Testing?

Professional radon testing is carried out by certified measurement specialists using advanced equipment—such as continuous radon monitors (CRMs)—that offer precise and real-time data. These experts follow EPA protocols to ensure accurate readings, interpret results clearly, and recommend next steps when mitigation is necessary.

Benefits of Hiring a Professional:

• Reliable results: Testing is performed under strict standards.

• Expert guidance: Professionals explain results and mitigation options clearly.

• Peace of mind: Especially important during real estate transactions or after previous elevated readings.

• More advanced tools: Equipment like CRMs provide hour-by-hour data for better decision-making.

What Does It Cost?

Professional radon testing in Colorado typically ranges between $150 and $250, depending on the size and layout of the home. While the upfront cost is higher than DIY testing, it can help you avoid costly errors—and potentially serious health risks—down the line.

Which Option Is Right for You?

Here are a few things to consider when deciding between DIY and professional testing:

• Budget: DIY kits are affordable, but may require retesting if results are unclear.

• Urgency: Selling or buying a home? Professional testing is often required or strongly recommended.

• Accuracy needs: If you’ve never tested before or live in an area with high radon potential, start with professional testing for peace of mind.

• Comfort level: Are you confident interpreting results and managing next steps on your own?
