A Hidden Danger Beneath

This client's ranch home, with its finished basement and dirt crawlspace, harbored an invisible threat: radon levels of 13. The only unfinished area was a small HVAC room, with no sump pit, just a wastewater grinder. The client, already facing a lung mass, needed swift action. Plans were made to install a sub-slab extraction point by the water heater, routing into the crawlspace. The joists could have worked for venting, but the insulation, held by chicken wire mesh, complicated things. Instead, two cores would be drilled through the foundation walls. The client would clear out debris beforehand, and we’d encapsulate the space, setting a second extraction point to vent through the soffit. Everything worked out as planned.

Radon Mitigation for the Dinapolis' New Home: Addressing Crawlspace & Basement Risks

When the Dinapolis family purchased their new home, they were already one step ahead in protecting their investment and health. With radon levels testing between 10–11 pCi/L, and a 4-foot crawlspace accessible from the back of the house, radon mitigation was a clear next move. Thanks to Realtor Charlie Sutton, who had already helped the seller patch floors and seal visible cracks, the home was prepped for an efficient install. Our team designed a 2-point radon mitigation system, one extraction point in the basement and another in the crawlspace. We paid special attention to an old coal chute in the crawlspace, sealing it thoroughly to reduce radon infiltration. This approach provided a cost-effective radon reduction solution tailored to the home’s layout; giving the Dinapolis family peace of mind from the start.

Radon Mitigation for Ranch Home with High Levels and No Drain Tile

This ranch-style home had radon levels of 22.0 pCi/L, well above the EPA action level. While the basement had a sump pit, it lacked drain tile, and the layout included two main chambers separated by a stem wall with footings. To ensure proper radon reduction, a 3-point extraction system was designed:

• Point one near the plumbing stack
• Point two approximately 12 feet away in the basement corner
• Point three on the opposite side of the stem wall

The mitigation system will exit through the rim joist on the north side of the home. The homeowner expressed interest in the Breathe EZ air purification and duct cleaning, but will wait due to budget. Despite structural limitations, this setup delivers a strong foundation for radon abatement, protecting the home's air quality and ensuring a safer living space.

Should I Buy a Home with a Radon Mitigation System?

The customer was preparing to sell their house and wanted to avoid any surprises during the inspection process. Knowing that radon testing is common in real estate transactions, they decided to preemptively check for radon. The results showed elevated levels. To ensure the home was market-ready, they hired a radon mitigation service to install a system. With the radon levels under control, they successfully marketed the home as a safe and healthy environment, which helped reassure potential buyers and expedite the sale.

To mitigate radon gas from all entry points in a home, we have to take sumps into consideration. In this home, we installed a two extraction point radon mitigation system and added a new sump pit pump with a discharge line and a cover. We dug the sump pit lower so we could properly install the sump pump, put in a new discharge and seal the pit.
