Radon System Installation in Rapid City, SD

Full Radon Mitigation System Installation

When radon testing confirms that your home has elevated levels, the next step is installing a professionally engineered radon mitigation system. Our installation service covers every component of a complete radon reduction system, from the suction point beneath your slab to the exhaust point above your roofline. We handle every detail so you can focus on what matters most — keeping your family safe.

A radon mitigation system is a permanent addition to your home that actively removes radon gas from the soil beneath your foundation before it can enter your living space. The core of every system we install is a network of sealed PVC piping connected to an inline radon fan that creates negative pressure under your slab. This continuous suction draws radon-laden soil gas through the piping and exhausts it safely above the roof where it disperses harmlessly into the open air. The system runs 24 hours a day, 7 days a week, consuming roughly the same energy as a 75-watt light bulb.

Every installation begins with a thorough assessment of your home's foundation type, construction materials, soil conditions, and radon entry points. No two homes in Rapid City are identical, and the geological diversity of the Black Hills region means that soil gas communication can vary significantly even between neighboring properties. That is why we custom-design every system to match the specific conditions of your home rather than using a one-size-fits-all approach.

System Components We Install

A complete radon mitigation system includes several integrated components, each of which plays a critical role in system performance:

• Suction Point — A 4-inch hole cored through your basement slab or foundation, creating the collection point for radon gas. We excavate a small pit beneath the slab to improve airflow and soil communication.
• PVC Piping — Schedule 40 PVC pipe (3" or 4" diameter) routed from the suction point through the interior of your home and out through the roof or an exterior wall. All joints are sealed with PVC primer and cement.
• Inline Radon Fan — A purpose-built, continuously rated fan mounted in the attic or on the exterior of your home. Our fans are selected based on the specific airflow and pressure requirements of your installation.
• Exhaust Point — The discharge point above your roofline, positioned away from windows and air intakes per EPA guidelines. Radon is vented safely into the atmosphere where it dilutes to harmless concentrations.
• U-Tube Manometer — A visual pressure gauge installed on the piping in your basement that allows you to verify system operation at a glance. If the liquid levels are uneven, your system is running properly.
• Sealant and Caulking — Polyurethane caulk applied to all visible foundation cracks, pipe penetrations, sump pit lids, and other potential radon entry points to maximize system performance.
