Radon Systems Installation Made Simple, Seamless, and Stress-Free

Realistically, you might not think about radon until a test comes back with results that are hard to ignore. What those results reveal is that radon has likely been seeping into your home for years, finding its way in through foundation cracks, slab joints, sump holes, and other vulnerable entry points. Addressing the problem starts with understanding exactly where radon is entering and selecting a system that targets those specific entry points with precision. Professional radon systems installation is the most reliable way to ensure that the right system is matched to the right problem and fitted correctly from day one.


At Radon Systems of Connecticut, every installation is something we take seriously on every single job. Our contractors are trained to assess each home's unique construction, identify every potential radon entry point, and fit each component, from vent pipes to exhaust fans, with the accuracy that effective radon reduction demands. We factor in everything from your foundation type and home's age to your radon levels and budget before a single component is put in place. Our track record of precise, EPA-compliant installations speaks for itself.


A well-executed radon system should be efficient, unobtrusive, and built to perform at its best for years without constant maintenance. We complete most installations in a single day, working cleanly and efficiently so your routine stays as undisturbed as possible. Every installation we carry out is followed up with monitoring to confirm your radon levels have come down to a safe range. Contact us today and our contractors will assess your home and deliver a radon systems installation that your family can count on for years to come.

The Installation Process Behind Each of Our Radon Systems

Precision matters at every stage of radon systems installation, from the placement of the vent pipe to the positioning of the exhaust fan and everything in between. Our contractors follow a proven process for each system we install, making sure every component is fitted correctly and performing at its best from day one.


  • Active Soil Depressurization: We create a suction point beneath your home's foundation and connect a vent pipe that routes either through your home's interior up to the roof or along the outside of your foundation, depending on your layout and personal preference. An exhaust fan is then fitted to the pipe to create a continuous vacuum that draws radon gas away from beneath your home and safely vents it above the roofline, delivering reductions of up to 80 to 99% in radon levels.
  • Active Sub-Slab Depressurization: Starting with a small hole drilled through your home's slab, we insert a pipe that connects directly to the soil beneath your home's structure and fit an exhaust fan to pull radon gas up through the pipe and vent it safely above the roofline. Every entry point around the pipe is then carefully sealed to prevent radon from finding alternative pathways into your living spaces, ensuring maximum effectiveness.
  • Crawlspace Sub-Membrane Depressurization: Thick, durable plastic membrane is laid across the crawlspace floor and partially up the walls, with edges carefully sealed to create an airtight barrier between the soil and your living spaces above, a process also commonly referred to as crawl space sub-membrane suction. We then fit a vent pipe and exhaust fan beneath the membrane to draw radon gas out from under it and vent it safely outdoors, away from your home's living areas.
  • Drain Tile Depressurization: Taking full advantage of your home's existing drain tile network, we connect a radon fan directly to the system and route a vent pipe up and out above the roofline, keeping your indoor air clean and your radon levels in check. Because the infrastructure is already in place, this installation requires no major structural modifications and is completed with minimal disruption to your home and daily routine.
  • Sump Pump Radon Mitigation: A sealed, airtight cover is fitted over your existing sump pit, using a method also known as sump hole suction, and connected to a vent pipe and radon fan, creating a contained system that draws radon gas out of the pit and vents it safely above the roofline. The sealed cover ensures radon has no pathway to escape into your living spaces, while the fan runs continuously to keep your indoor radon levels safely down.
  • Block Wall Depressurization: Small access points are drilled into your home's hollow concrete block foundation walls and connected to a radon fan that depressurizes the air space within the blocks, pulling radon out before it has a chance to migrate into your living spaces. A vent pipe then carries the extracted gas up and out above the roofline, keeping your indoor air clean and your radon levels within a safe range.

Frequently Asked Questions

  • Can a radon system be installed in a home that's currently being built?

    Yes, and it's actually one of the best times to have a radon system installed, as new construction allows us to integrate passive or active radon systems into the home's foundation before the build is complete. Installing a system during construction is typically less invasive and more cost-effective than retrofitting an existing home.

  • Can radon systems be installed in older homes?

    Absolutely, and we've installed radon systems in homes of all ages and construction types, including those with older foundations that present unique challenges. Our contractors are trained to identify the most effective installation approach regardless of your home's age or construction.

  • Do I need to test for radon before getting a system installed?

    Yes, radon testing is an essential first step as it confirms the presence and severity of your radon problem and helps us determine which system is the right fit for your home. While radon test kits are available for home use, we conduct a thorough professional radon test as part of our on-site assessment before recommending any installation.

  • Can a radon system be installed without affecting my home's existing ventilation?

    Yes, radon systems are designed to work independently of your home's existing ventilation system, venting radon gas directly above the roofline without interfering with your home's normal airflow. Our contractors take your home's existing ventilation into account during the assessment to ensure the installation has no negative impact on your home's air circulation.

  • Can multiple radon systems be installed in the same home?

    Yes, larger homes or homes with complex foundation types sometimes require more than one radon system to effectively address all radon entry points. Our on-site assessment allows us to identify exactly how many systems your home needs and where each one should be installed for maximum effectiveness.
