Radon Environmental Services

What Radon Environmental Services does

Radon Environmental Services of Toledo, Inc., doing business as Radon Ohio, is a privately held, family-owned environmental services company founded in 1988 by James Mann in Toledo, Ohio. The company is Ohio Department of Health–licensed and operates with a small, tenured team led by second-generation Owner/Operator Erinn Wilson following the October 2025 death of co-owner J. Peter Mann. Its service territory spans Northwest Ohio, North Central Ohio, and Southeast Michigan, with a Vermillion, OH office supplementing its Toledo headquarters.

The company's core offering is radon testing and mitigation for residential properties, supplemented by vapor intrusion mitigation, school district testing, HUD multifamily compliance work, and the Radon Home Protection Program for new construction. Its technology stack centers on conventional soil depressurization engineering: Continuous Radon Monitors (CRMs) for hourly, tamper-evident measurement; activated carbon test kits; sub-slab, draintile, sub-membrane (crawl space), and attic-installed mitigation systems; and vapor barriers plus vapor matting for chemical vapor intrusion. The firm guarantees post-mitigation levels below the EPA action level of 4.0 pCi/L and offers an annual Service Agreement that underwrites a lifetime fan warranty.

Commercially, Radon Environmental Services runs a direct-to-consumer, education-led inbound model with a small enterprise field-sales overlay for schools and HUD properties. Pricing is unit-based: CRM real-estate tests start at $145 for a 48-hour test, mitigation runs $1,000–$3,000 depending on foundation type, RHPP new-construction projects are custom-priced under multi-year contracts, and an annual subscription covers post-install inspection and warranty. Revenue streams are predominantly one-time installations and tests, with a small but structurally important recurring component from the annual Service Agreement. The company has no disclosed external funding and operates from two offices in Ohio.

Others

• Radonaway: Radonaway is a leading manufacturer of radon mitigation fans, vent pipes, and system components supplied to radon mitigation contractors. Not a direct competitor but an upstream supplier that Radon Environmental Services' installations depend on, and adjacent to the company's core radon mitigation business.

Broad incumbents

• PSI (Professional Service Industries): PSI is a large national engineering and environmental testing firm that includes radon measurement and Phase I/II ESA services. Comparable to Radon Environmental Services' commercial radon testing and vapor intrusion capabilities though operating as a much larger diversified testing incumbent.
• Terracon Consultants: Terracon is a large national environmental, geotechnical, and construction materials testing firm that performs environmental site assessments and indoor air quality work including radon. Broader in scope than Radon Environmental Services but overlaps on commercial radon testing and vapor intrusion consulting for real estate transactions.
• ECS Group of Companies: ECS is a major national provider of environmental, geotechnical, and building enclosure consulting including radon testing and indoor air quality assessments. Comparable as a broad incumbent serving commercial and institutional clients where Radon Environmental Services addresses the residential/school/HUD segments.

Direct peers

• SWAT Environmental: SWAT Environmental is the largest dedicated radon testing and mitigation company in the United States, operating across multiple states with franchise locations. Directly comparable to Radon Environmental Services in core services (radon testing, sub-slab/sub-membrane mitigation, new construction) though at much larger national scale.
• AirChek: AirChek is a leading radon test kit distributor and measurement services provider operating nationally via mail-order CRM and charcoal canister kits. Directly comparable to Radon Environmental Services' radon testing stream, though focused on DIY/professional mail-in testing rather than on-site field service.
• AccuStar Labs: AccuStar Labs (Sun Nuclear / AccuSense) is a national radon measurement laboratory and continuous radon monitor manufacturer serving home inspectors and mitigation contractors. Comparable to Radon Environmental Services on the testing/measurement side and as a CRM supplier to the radon industry.

Emerging players

• AAT Environmental Services: AAT Environmental Services provides radon testing and mitigation across portions of the Midwest and Mid-Atlantic. Overlaps with Radon Environmental Services on testing and mitigation services in a partial geographic footprint, representing an emerging multi-region player rather than a national incumbent.

Regional players

• NJ Radon Measurement & Mitigation: Regional radon testing and mitigation provider serving New Jersey and surrounding states. Comparable in core offering (CRM testing, sub-slab depressurization) but does not overlap geographically with Radon Environmental Services' Ohio/Michigan service territory.
• HomeSpec / BasementFix: HomeSpec BasementFix is a regional home repair and waterproofing company in the Midwest that offers radon mitigation as part of a broader basement waterproofing and foundation repair portfolio. Comparable to Radon Environmental Services' mitigation services but offered as an add-on within a wider home services bundle rather than a radon specialist.
