Helping Clients Navigate Radon Concerns with Confidence

What Is Radon, and Why Should Homeowners Care?

Radon is a colorless, odorless gas that forms naturally from the breakdown of uranium in soil, rock, and water. It can seep into homes through foundation cracks, sump pumps, crawl spaces, and even well water. When it accumulates indoors, particularly in basements or lower levels, it becomes a health risk.

The primary concern? Long-term exposure to elevated radon levels is the second leading cause of lung cancer in the United States, according to the EPA. This is especially critical for non-smokers, who might not expect they’re at risk.

Still, it’s important to note: the presence of radon doesn’t mean panic—it means awareness and action.

When Do Radon Concerns Usually Arise?

Radon concerns typically come to light during several key moments:

1. Real Estate Transactions

Whether buying or selling, radon testing has become a standard part of home inspections in many states. Buyers want assurance that a home doesn’t pose hidden health risks, while sellers may proactively test to avoid delays in closing.

2. Health Awareness

Some families discover radon after learning about its link to lung cancer. A concern for children's health, aging parents, or their own long-term well-being may drive homeowners to test.

3. Home Renovations

Projects like finishing a basement or encapsulating a crawl space can shift airflow and create conditions that increase radon entry. Testing before and after such changes is a smart preventive measure.

Understanding Radon Testing: What Clients Need to Know

There are two primary types of radon tests: short-term (2–7 days) and long-term (90+ days). Both measure radon levels in picocuries per liter (pCi/L). The EPA recommends action if levels are 4.0 pCi/L or higher, though even lower levels can carry risk.

Testing Tips for Clients:

• Start with short-term tests if time is limited, such as during a home purchase.

• Use certified professionals or reliable DIY kits from trusted sources.

• Test the lowest livable area, especially if there’s a finished basement.

Testing is not a one-time event. Encourage clients to retest after mitigation, major renovations, or every couple of years for peace of mind

Radon Mitigation: Addressing the Problem Without Panic

If elevated radon levels are found, mitigation is the next step—but it doesn’t have to be overwhelming.

What Does a Radon Mitigation System Do?

Most systems work by venting radon gas from beneath the home to the outside using fans and piping. The most common type is a sub-slab depressurization system installed in basements or slab foundations. In crawl spaces, encapsulation plus venting may be used.

Key Messages to Share with Clients:

• Radon can be reduced to safer levels. No home is immune, but most radon problems are fixable.

• Mitigation is affordable. Most systems cost less than $2500, depending on the home.

• Professional help matters. Certified radon contractors understand building science and local regulations.

How Professionals Can Support Clients with Confidence

As a real estate agent, home inspector, or contractor, your role is to translate complex risks into manageable steps for your clients.

Ways to Reassure and Guide:

• Normalize radon as part of homeownership. Just like mold or termites, it’s a concern that can be addressed.

• Frame it as a value-added solution. A mitigated home can actually be more attractive to buyers.

• Provide credible resources. Point clients to EPA guidance, local radon programs, and certified mitigation providers.

Sample Talking Point:

“Radon is common in many areas, but it’s not a deal-breaker. Testing gives us clarity, and mitigation is a smart, long-term investment in your home and health.”

Tips for Clients: Navigating Radon Like a Pro

Empower clients with these clear action steps:

• Test early in the home-buying or remodeling process

• Review test results with a professional who can explain them

• Get multiple quotes from certified mitigation contractors

• Retest after mitigation to ensure the system is effective

• Maintain systems regularly to preserve indoor air quality

Busting Common Radon Myths

Myth 1: Only homes with basements have radon
Truth: Radon can enter any type of home—basement, crawl space, or slab.

Myth 2: New homes don’t have radon problems
Truth: New construction is not immune. In fact, tighter energy-efficient homes can trap radon more easily.

Myth 3: You can’t sell a home with radon
Truth: Homes with mitigation systems often appeal more to health-conscious buyers.

When in Doubt, Seek Expert Help

Radon isn’t something to ignore—but it’s also not something to fear. With the right information, testing, and mitigation strategies, clients can feel empowered to make decisions that protect their families and investments.

Final Thoughts: Confidence Starts with Clarity

Helping your clients navigate radon concerns is ultimately about building trust. Whether you're an agent, inspector, or contractor, your calm and informed approach will make a difference.

When questions arise, direct them to certified radon professionals and reputable sources like the EPA. And if you're a homeowner yourself—don’t wait. Test today and breathe easier tomorrow.
