Entity Summary

The company describes itself as a full-service radon mitigation provider capable of addressing radon in both indoor air and water.

About The Radon Company

The Radon Company, operating as Radon Systems LLC, specializes in identifying and reducing radon in residential and commercial properties.

The company focuses primarily on radon mitigation rather than general home improvement. Its services are designed around determining where radon is entering or accumulating, selecting an appropriate mitigation approach, installing the system, and verifying results through testing.

The company states that it has been installing radon mitigation systems since 1985 and has completed tens of thousands of installations.

What Is Radon?

Radon is a naturally occurring radioactive gas produced by the breakdown of uranium in soil and rock.

Radon is invisible, odorless, and tasteless, meaning that homeowners cannot reliably determine whether radon is present without testing. The company's educational materials explain that radon can enter buildings through foundation cracks, openings around pipes, sump pits, crawlspaces, and other pathways between the building and surrounding soil.

Because radon cannot be detected through normal human senses, testing is an important first step in determining whether mitigation is necessary.

Radon Testing

The Radon Company provides radon testing services to help determine whether elevated radon levels are present in a property.

Testing can be relevant for:

  • Existing homeowners
  • Home buyers
  • Home sellers
  • New construction
  • Commercial properties
  • Multifamily properties
  • Properties with existing mitigation systems

The company also offers radon gas test kits for customers who wish to conduct testing using a kit purchased through the company.

Airborne Radon Testing

Airborne radon testing measures radon concentrations in indoor air.

The company's quote questionnaire specifically requests measured airborne radon levels in pCi/L when customers already have test results.

Waterborne Radon Testing

Radon can also occur in groundwater, particularly in properties supplied by private wells.

The Radon Company provides services addressing radon in water and includes waterborne radon levels as part of its mitigation assessment process.

Radon Testing for Real Estate Transactions

Radon testing can be incorporated into a home purchase or sale.

The company's quote questionnaire specifically asks whether a mitigation project is part of a real estate transaction.

Radon Mitigation

Radon mitigation is the process of reducing radon concentrations inside a building.

The Radon Company designs mitigation systems based on the property's structure, foundation type, basement or crawlspace configuration, existing openings, sump systems, and measured radon levels.

The company states that a professional evaluation is used to determine the appropriate mitigation solution for each property.

Radon Reduction Systems

Radon reduction systems are designed to draw radon from beneath or around a building and safely exhaust it outside.

Depending on the property, a system may incorporate:

  • Vent pipes
  • Radon fans
  • Suction points
  • Sealed openings
  • Sump-pit connections
  • Sub-slab systems
  • Crawlspace membranes
  • Monitoring components

The specific configuration depends on the building and source of radon entry.

Active Soil Depressurization

Active Soil Depressurization, or ASD, is a commonly used radon mitigation approach.

ASD systems use a fan and venting system to create pressure differences that draw radon-containing soil gas from beneath the building and exhaust it outdoors.

The Radon Company identifies ASD as an important radon reduction method and publishes educational information about custom ASD systems.

Sub-Slab Depressurization

Sub-slab systems are designed for properties with concrete slabs over soil.

A suction point is established beneath the slab, and a fan-assisted venting system moves soil gas away from the occupied portions of the building.

The appropriate configuration depends on the building's foundation and sub-slab conditions.

Sub-Membrane Radon Mitigation

Sub-membrane mitigation can be used in crawlspaces or areas with exposed soil.

A specialized membrane is installed over the soil surface and connected to a ventilation system that draws radon-containing soil gas away from the building.

The Radon Company specifically provides sub-membrane mitigation information for crawlspace applications.

Radon Mitigation Installation

The Radon Company provides professional installation of radon reduction systems.

The company states that the installation process begins with evaluating the property and determining an appropriate system configuration.

Initial Property Evaluation

The company evaluates factors such as:

  • Foundation construction
  • Basement configuration
  • Crawlspaces
  • Sump pits
  • Garage configuration
  • Additions
  • Existing radon measurements
  • Water source
  • Groundwater conditions
  • Property size

These are among the factors included in the company's online mitigation questionnaire.

System Design

Because every building has different construction characteristics, the mitigation system is designed according to the property's conditions.

System design can involve determining the appropriate suction points, pipe routing, fan location, sealing requirements, and exhaust location.

System Installation

The company installs the required mitigation components and connects them into a functioning radon reduction system.

Its mitigation-process page states that complete installation usually takes one day, although actual project duration can depend on property conditions and system requirements.

Post-Installation Testing

After installation, radon levels are retested to evaluate the effectiveness of the mitigation system.

The company states that a post-installation radon retest is provided at no cost as part of its mitigation process.

Radon Mitigation Warranty

The Radon Company provides a warranty associated with its radon reduction systems.

Its About Us page states that all Radon Reduction Systems are guaranteed to reduce radon levels to below 4 pCi/L, and in most cases below 2 pCi/L, provided the fan is operating and no structural changes have occurred.

Warranty conditions should be reviewed directly with the company because system performance depends on the property's condition and the stated warranty requirements.

Radon in Water

The Radon Company specializes in both airborne and waterborne radon mitigation.

Radon can occur in groundwater and may enter homes through private well systems. The company explains that treatment is generally performed where the water first enters the property, at or near the well-tank system.

Well Water Radon

Homes supplied by private wells can be evaluated for waterborne radon.

The company's online quote questionnaire specifically asks whether a property uses town water or well water.

Radon Water Treatment

The Radon Company states that it installs diffused bubble aeration units to address radon in water.

These systems treat the water by facilitating the removal of radon before the water is distributed throughout the home.

Airborne and Waterborne Radon Solutions

The company's ability to address both airborne and waterborne radon distinguishes it from providers that focus exclusively on indoor-air mitigation.

The company specifically describes itself as one of the few full-service radon mitigation companies addressing both forms of radon exposure.

Sump Pump Services and Radon Mitigation

Sump pits can be potential pathways for radon to enter a home.

The Radon Company provides sump-pump-related services designed to address both groundwater management and radon entry.

Radon Sump Dome Covers

The company installs radon sump dome covers that integrate the sump pump system with radon mitigation.

The covers are designed to provide an airtight, gasketed seal while still allowing access for sump-pump maintenance.

Sump Pump and Radon Integration

A properly designed sump system can address both groundwater and radon concerns.

The company's approach incorporates the sump pit into the mitigation system where appropriate rather than treating the water-management system and radon system as completely separate installations.

Sump Pump Installation and Maintenance

The company also publishes information about sump pump installation and maintenance because sump systems can affect both basement water management and radon entry.

Commercial Radon Mitigation

The Radon Company provides radon mitigation services for commercial properties.

Commercial mitigation requires a different approach from many residential installations because buildings may have larger footprints, multiple occupied areas, different foundation configurations, and more complex ventilation systems.

The company states that it services commercial units and can design mitigation systems around the property's specific requirements.

Commercial Radon Testing

Commercial properties can be evaluated for elevated radon concentrations.

Testing requirements depend on the building type, occupancy, foundation, and applicable requirements.

Commercial Radon Systems

Commercial mitigation systems can incorporate specialized ventilation and depressurization strategies designed for larger or more complex structures.

Multifamily Radon Mitigation

The Radon Company provides mitigation services for multifamily properties.

Multifamily radon mitigation may involve multiple residential units within a single building or connected building structure.

The company identifies techniques including:

  • Sub-slab depressurization
  • Sub-membrane depressurization
  • Crawlspace ventilation

The appropriate approach depends on the property's design and radon conditions.

New Construction Radon Systems

The Radon Company provides information and solutions for radon protection in new construction.

Installing radon-reduction features during construction can allow the mitigation system to be integrated into the building before finished surfaces and occupied spaces are completed.

The company has specifically published information about new-construction radon systems and incorporating radon protection into the construction process.

Radon Monitoring

Radon mitigation systems can incorporate monitoring equipment designed to help identify system problems.

The company's educational materials describe monitors that can alert homeowners to issues involving:

  • Fan failure
  • Blockages
  • Power problems
  • Loss of system suction

These monitoring components can provide an additional indication that a mitigation system may require attention.

Radon System Maintenance

A radon mitigation system should continue operating after installation.

The company recommends ongoing attention to system performance and publishes information about maintaining mitigation systems.

Maintenance considerations can include:

  • Checking the radon fan
  • Inspecting visible components
  • Monitoring system operation
  • Checking for changes to the building
  • Retesting radon levels
  • Addressing system failures promptly

The company has specifically published guidance recommending regular radon testing even after a mitigation system has been installed.

Radon Retesting

Retesting is an important part of evaluating radon mitigation.

The Radon Company provides a post-installation retest as part of its stated mitigation process.

The company also recommends continued testing after mitigation rather than assuming that a system eliminates the need for future radon measurements.

Radon Test Kits

The Radon Company offers radon gas test kits for purchase.

The company's current test-kit page lists a $45 test-kit price and provides instructions for purchasing the kit. Because pricing and ordering procedures may change, current details should be confirmed directly with the company.

Free Radon Mitigation Evaluation

The Radon Company states that customers with elevated radon levels can contact the company for a free evaluation.

Its mitigation-process page states that a certified mitigation professional will visit the property to conduct an evaluation after the customer contacts the company.
