Radon Mitigation Systems Built for Long-Term Protection & Performance

Every home is different, and the right radon mitigation system depends on your home's foundation type, construction, and radon levels. We assess your specific situation carefully and recommend the system that will bring your radon levels down most effectively and keep them there.


  • Active Soil Depressurization: The most widely used and effective radon mitigation method available today, and a significant step up from passive systems, is Active Soil Depressurization (ASD), which works by creating a pressure differential that draws radon gas away from beneath your home before it can enter your living spaces. We offer both interior and exterior installations depending on your home's layout and personal preference. The interior system routes a pipe up to the roof, while the exterior system runs along the outside of your foundation for a cleaner, less intrusive look.
  • Active Sub-Slab Depressurization: For slab-on-grade homes, one of the most effective approaches involves inserting a pipe directly into the slab to extract radon gas from the soil beneath your home's structure, a method known as Active Sub-Slab Depressurization. A radon fan then pulls the gas up through the pipe and safely vents it above the roofline, well away from your living areas. This method is particularly effective at addressing radon in the soil, which can also have a negative impact on your home's water supply.
  • Crawlspace Sub-Membrane Depressurization: Homes with crawlspaces have a dedicated solution in Crawlspace Sub-Membrane Depressurization, which works by placing a durable membrane over the crawlspace floor to block radon from seeping up into your home. A radon fan then draws the trapped gas from beneath the membrane and vents it safely outdoors, away from your living spaces. As an added benefit, this method also helps control moisture levels in the crawlspace, offering an extra layer of protection for your home's overall structure.
  • Drain Tile Depressurization: If your home already has a drain tile system, we can put it to good use against radon through a method called Drain Tile Depressurization, which connects a radon fan directly to your existing drain tile network without any major structural changes. The fan draws radon gas out from beneath your foundation and vents it safely above the roofline, keeping your indoor air clean and your radon levels in check. This makes it a smart, cost-effective solution that takes full advantage of the infrastructure already in place in your home.
  • Sump Pump Radon Mitigation: Homes with an existing sump pump system have a natural advantage, as the sump pit can serve as an ideal collection point for radon gas through a method called Sump Pump Radon Mitigation. A sealed cover is placed over the sump pit and connected to a radon fan that draws the gas out and vents it safely above the roofline. This approach is minimally invasive and highly practical, making it a popular choice for homeowners who want an effective radon solution without major modifications to their home.
  • Block Wall Depressurization: Hollow concrete block foundation walls can act as hidden pathways for radon gas to travel into your living spaces, and Block Wall Depressurization is the specialized method designed to address exactly that problem. This system works by depressurizing the air space within the block walls, pulling radon out before it has a chance to migrate into your home. It's a highly targeted approach that works particularly well for older homes built with this specific type of foundation construction.

Frequently Asked Questions

  • How long does a radon mitigation system installation take?

    In most cases, we can complete a full radon mitigation system installation in a single day, with minimal disruption to your daily routine. The exact timeline depends on your home's size, foundation type, and the mitigation method we recommend.

  • How much does radon mitigation cost?

    The cost of radon mitigation varies depending on your home's foundation type, size, and the severity of your radon problem, but most installations are comparable in cost to other common household repairs. We provide a free, no-obligation estimate after our on-site assessment so you know exactly what to expect before any work begins.

  • Will a radon mitigation system completely eliminate radon from my home?

    While no system can reduce radon levels to absolute zero, a properly installed radon mitigation system can reduce your indoor radon levels by up to 99%, bringing them well within the EPA's recommended safe range. We follow up after every installation to confirm your levels have dropped to a safe and acceptable range.

  • How long does a radon mitigation system last?

    A well-installed radon mitigation system can last for many years, often exceeding 10 to 20 years with proper maintenance and monitoring. We install a radon monitor with every system so you always have real-time visibility into your home's radon levels.

  • Does a radon mitigation system require a lot of maintenance?

    Radon mitigation systems are designed to run continuously with very little maintenance required on your end. We recommend periodic checks of your system's components and fan to make sure everything is functioning as intended, and we're always available if you notice anything unusual.
