Radon Systems

What Radon Systems does

Radon Systems LLC is a Sutton, Massachusetts-based privately held company founded in 1985 that provides radon mitigation services for residential, multifamily, and commercial properties across Massachusetts, Connecticut, and Rhode Island. Operating under the trade name "The Radon Company," the firm claims more than 30,000 radon mitigation systems installed since inception and is one of the few full-service providers addressing both airborne radon and radon in water.

Its technical portfolio covers multiple mitigation modalities. For airborne radon, the company installs Active Soil Depressurization (ASD) systems that create negative pressure beneath foundations, Sub-Membrane Ventilation Systems (SMVS) for slab-on-grade or crawlspace applications, and Heat Recovery Ventilation (HRV) systems that exchange indoor air while recovering heat. For radon in well water, the company deploys Diffused Bubble Aeration units at the well tank entry point. Ancillary services include sump pump installation and repair, sub-slab ventilation for environmental remediation of TCEs, VOCs, and oil spills in collaboration with environmental firms and EPA/DEP, and dedicated multihome radon systems. Radon test kits are sold directly to consumers at $45 each.

The business runs a sales-led go-to-market model anchored on inbound phone calls (800-669-6697), website quote requests, and on-site contractor visits with a quoted one-business-day turnaround. Revenue is generated primarily through professional services fees for mitigation installations, supplemented by test kit sales, sump pump services, and environmental remediation contracts. The company is state-certified, fully insured, recognized by NEHA and AARST, holds a BBB A+ rating, has received the Angie's List Super Service Award for three consecutive years, and operates as a Radon Away Authorized Pro.

• Enviro Radon: Regional radon mitigation contractor focused on residential and light commercial mitigation systems. Material overlap in technology (sub-slab depressurization) and customer segment.
• Aegis Radon Mitigation: Regional radon mitigation company providing residential radon testing and mitigation using ASD and sub-membrane systems. Comparable service mix and target customer.

Others

• AARST (American Association of Radon Scientists and Technologists): Industry trade association that sets standards and certifies radon professionals.

• Radon Away: Manufacturer and supplier of radon mitigation fans and equipment; Radon Systems is an Authorized Pro partner. Comparable in ecosystem role but acts as a supplier rather than a direct service competitor.

Regional players

• All Radon Solutions: Regional radon mitigation company offering testing and mitigation with similar system types. Operates in a different geographic market but mirrors Radon Systems' service model.
