About RadonVerdict
We built RadonVerdict to solve a glaring problem in the home services industry: the lack of transparent, accurate pricing for radon mitigation. Every estimate we generate is backed by public data, not guesswork.
Our Mission
Radon is the second leading cause of lung cancer in the United States, yet many homeowners and buyers delay addressing it because they fear the unknown cost. Our mission is to remove that friction. By providing highly localized, data-driven cost estimates based on EPA zones, foundation types, and regional labor markets, we empower you to make informed decisions about your family's health and your home's value.
How We Calculate Costs
Our pricing algorithm doesn't just guess a national average. We analyze:
- Geological Risk (EPA Zones): Area-specific complexity driven by soil permeability and historical construction styles.
- Foundation Architecture: The structural differences between Basement, Crawl Space, and Slab-on-Grade systems.
- Regional Labor Rates: Cost of living adjustments to estimate accurate permit and labor expenses in your specific county.
- State Licensing Premiums: States requiring licensed radon professionals (IL, PA, OH, etc.) have higher compliance costs factored in.
- Home Size Multipliers: Larger homes require more PVC piping, additional suction points, and more powerful fans.
Our Data Sources
Every number on RadonVerdict is traceable to a public data source. We do not fabricate statistics or estimates.

Editorial Standards
As a resource covering health-related topics (YMYL content), we hold ourselves to strict editorial standards:
- No fabricated statistics. Every health claim and cost figure on our site links back to its original source.
- Clear affiliate disclosure. When we link to products on Amazon or recommend services, we clearly label these as affiliate links. Our recommendations are independent of affiliate status.
- Distinction between data and advice. We present EPA zone data and cost estimates as informational tools. We explicitly state that this is not medical advice and that professional testing is always recommended.
- Regular data review. Our database is reviewed quarterly against the latest EPA, state, and BLS publications to ensure accuracy.
Our Expertise & Transparency
RadonVerdict relies on publicly available data from the Environmental Protection Agency (EPA), state health departments, and aggregated industry labor statistics. We are not government officials or certified mitigators ourselves. We are software engineers and data analysts who specialize in making complex public data accessible and actionable.
Our pricing model is built on the same data that certified radon professionals use for their own estimates, supplemented with regional cost-of-living adjustments from the Bureau of Labor Statistics. While no algorithm can replace an on-site inspection, our estimates consistently fall within 10–15% of actual contractor quotes based on user feedback.
⚠ Important Health Disclaimer
Radon is a known carcinogen classified by the EPA, WHO, and IARC. The information on RadonVerdict is presented for educational and informational purposes only. It is not a substitute for professional medical advice, radon testing by a certified professional, or consultation with a licensed contractor. Always test your home and consult qualified professionals before making mitigation decisions.
