Myths vs. Facts: What Homebuyers Need to Know About Mold and Radon

When you’re buying a home, few topics create more confusion than mold and radon. Buyers often hear conflicting advice from friends, online sources, and even real estate professionals. Some think these issues are overblown—others believe they’re deal-breakers. The truth lies somewhere in the middle, and understanding the real risks (and solutions) can help you make a confident, informed decision.

This guide breaks down the most common myths and facts so buyers know what truly matters during an inspection.

Myth #1: “Mold is always a major health hazard.”

Fact: Mold ranges widely—from minor surface growth caused by poor ventilation to significant contamination that requires remediation.
The key is identifying why mold is present. A skilled inspector evaluates moisture sources, ventilation issues, and areas prone to water intrusion. When needed, lab testing provides precise, unbiased results to guide the right next steps.

Myth #2: “If you don’t see mold, it’s not there.”

Fact: Many mold issues are hidden.
Mold can grow behind drywall, inside attic spaces, beneath flooring, or around insulation. Professional tools—such as thermal imaging and moisture meters—help detect hidden moisture patterns that indicate possible mold growth. Testing provides clarity you can’t get from a visual look alone.

Myth #3: “Radon isn’t a concern in newer homes.”

Fact: Radon can impact homes of any age, style, or construction.
Radon originates from the soil, not the age of the structure. Whether it’s new construction or a century-old home, the only way to know your radon levels is through specialized testing.

Myth #4: “If radon levels are high, you should walk away.”

Fact: Radon is one of the most easily corrected issues in real estate.
A radon mitigation system can often be installed in a single day and provides long-term, reliable reduction. Elevated radon should prompt negotiations—not fear.

Myth #5: “Opening windows will fix radon problems.”

Fact: Opening windows may temporarily lower readings, but it does not resolve the issue.
Radon levels fluctuate constantly. Only a properly designed mitigation system provides consistent, long-term results.

Myth #6: “Testing isn’t necessary if the home looks fine.”

Fact: Both mold and radon can be completely invisible.
A home may appear spotless and still have elevated radon or hidden moisture problems. Testing gives buyers real data, not assumptions.

Why Mold and Radon Testing Matters for Buyers

  • Protects indoor air quality

  • Identifies issues before they worsen

  • Strengthens negotiation leverage

  • Ensures long-term safety and comfort

A home with mold or radon isn’t necessarily a “bad” home—it simply needs proper evaluation and, if needed, straightforward correction.
