Radon Mitigation Technology

Current radon mitigation technology offers reliable, proven techniques for reducing radon levels in virtually any home or property, including commercial and new construction.

How Does It Work?

  • Radon mitigation systems create a closed path for radon gas to divert outside via PVC piping, so it cannot re-enter a home or building.
  • These systems use a radon fan that operates 24/7/365, and pulls radon gas from below a concrete slab and through PVC piping. The radon gas then exits the building and dissipates outside, well above the roofline.
  • Any radon mitigation system should be installed in accordance with state license/certification standards or guidance. The US EPA recommends hiring a radon abatement service certified by either the National Radon Proficiency Program (NRPP) or the National Radon Safety Board (NRSB). (See "About Us" for our certified credentials.)

Our Approach to Radon Mitigation Systems

The radon mitigation techniques we use depend upon the home structure and property. Typically, they include active-slab depressurization (ASD) and sub-membrane depressurization (SMD).

MITIGATION DETAILS

Specific Elements of Certified Radon Mitigation Systems:

  • Cracks or openings in unfinished basement areas should be sealed, and sump cover lids should be sealed to prevent any loss of vacuum pressure.
  • Depending on the property, radon fans may be located in the attic, or mounted outside on a property’s exterior, or, if available, a garage attic.
  • The system should include a manometer gauge (visual vacuum "U"-tube indicator) located on pipe side in a prominent location near the building or home’s entry point. This enables an occupant to easily see if fan is functioning properly.
  • The radon fan’s power must be set up in accordance with local electric codes.
  • All portions of the radon mitigation system fan and above entry point on the pipe must be labeled.
  • The system must include a simple instruction manual sheet, with warranties provided to the homeowner.
  • New radon mitigation systems should be retested no sooner than 91 days after installation to verify reduction. The US EPA recommends testing every two years. 

Remember, all radon mitigation systems must adhere to EPA RMS guidelines. If you have questions about these standards, consult your radon mitigation specialist.

Safety and Work Environment

The Boulder Edge team takes your health and well-being seriously. We understand the significance of the role we play in minimizing risk for our customers through radon mitigation.

That awareness of risk extends to our on-site practices. We always want to ensure a safe work environment during the mitigation process, so Boulder Edge customarily implements US EPA Radon Mitigation Standards (RMS), Occupational Safety and Health Administration (OSHA) standards (equipped with air-quality, dust control, electrical, and chemical protection). That includes the use of Personal Protective Equipment (PPE) as an essential safety component of our services.

Our code-compliant procedure includes following all building codes regarding penetrating any firewall and re-supporting any structural bearing box joist.

All electrical work should meet or exceed local codes. The glues, solvents and materials that are used may be hazardous. You should not be in the work area during the installation. Material Safety Data Sheets (MSDS) will be supplied upon written request.

While work is in progress the windows will be opened and portable ventilation systems may be used. Workers should wear proper clothing suitable for this type of work, and wear eye, ear, and respiratory protection when necessary. Workers should be monitored for radon exposure during the work.

Boulder Edge’s priority is providing you with high-quality,
high-value solutions that put your health and safety first.
