Before:
A radon level of 4.2 pCi/L was detected in a home mid-renovation. With all drywall removed and the basement exposed, it provided an excellent opportunity to plan for clean air from the ground up.
After:
A one-pipe mitigation system was strategically placed in the utility room and routed through the center of the house. The clean internal route now vents safely through the roof, blending into future construction plans and ensuring the home’s safety without compromising design.
This home, built in the 1900s, tested at a radon level of 11 pCi/L and has two foundations: a main foundation and a crawl space. A three-pipe mitigation system was installed—two extraction points in the main foundation and one in the crawl space. The system was routed near the Bilco door, and cement work was required to seal the extraction points.
Before,
The client expressed uncertainty about the ideal placement of the radon mitigation system — either in the middle of the basement near the oil tank or in the corner of the house. The home, built in 1955 with one foundation and no sump pump or water guard, required careful planning due to the small layout and potential obstructions. Discussions were held with the client, and it was confirmed that they preferred Option 2, which was to install the system in the corner of the basement.
After,
Following the client’s decision, the team installed a single-pipe radon mitigation system in the designated corner of the house. The setup avoided major obstructions, respected the home’s existing structural elements, and optimized radon gas ventilation. The final system met performance and aesthetic expectations, keeping the space functional and effective for radon reduction.
The home tested at 7.9 pCi/L with no active radon mitigation system installed beneath the foundation.
A one-pipe radon mitigation system is planned near the basement window area to improve airflow beneath the slab and reduce radon levels throughout the home.
