With radon levels testing at 7.0 pCi/L, the home required a two-pipe system to effectively mitigate.
The current crawl space was previously unsealed and will be fully encapsulated during this job.

The homeowner also mentioned concern about a neighbor’s loud radon system, prompting us to ensure quiet system operation, likely with a better muffler solution or insulation.

After install, the radon system will route pipes strategically, with quiet airflow management and sealed sump or vent exits if present.
The before photos will show the unsealed dirt crawl space, and after photos will document the sealed environment and the full mitigation system in place.

Before:

• Dirt crawl space (12x5) exposed

• Small sump pump hole (4x2 inches) uncovered

• No encapsulation, radon level at 4.9 pCi/L

• Three unsealed foundations

After:

• Crawl space now encapsulated

• Sump pump hole sealed with cover

• All three foundations addressed

• Full system installed and exit point placed on left side of the home

Before: During the real estate transaction, it was identified that the home's basement system, part of an older mitigation setup, was unsealed, allowing radon levels to reach 7.1 pCi/L. After: After our intervention, where we sealed the basement system effectively, the home now maintains radon levels well below the EPA's action guidelines. This update not only ensures a safer environment but also aids in the smooth transition of property ownership.

Before our visit, the home had no existing mitigation and was registering high radon levels. After assessing the layout, we installed a two-pipe system with careful consideration for aesthetics and airflow. The laundry room and closet were selected for internal access points, minimizing disruption. Despite thick shrubbery on the exterior, the final install was tidy and efficient—leaving the home safer and ready for long-term occupancy.

Before: The home's complex basement configuration—with multiple foundation types, partially finished spaces, and limited routing options—made radon mitigation a unique challenge.
After: With two powerful systems expertly installed—one routed discreetly through the dumbwaiter closet near the furnace and another behind the chimney—we achieved a clean, efficient setup while maintaining the integrity of the living space.
