Two-Point Radon Mitigation System Planned for Sharon Home (Sump Pit / Interior Mitigation System)

Before:
The sump pit was covered with a temporary plywood lid that did not provide an airtight seal, allowing potential pathways for radon and soil gases to enter the basement.

After:
A custom sealed sump cover was installed and integrated into the radon mitigation system, creating an airtight seal around the sump opening and improving the system's ability to capture and safely vent radon from beneath the foundation.
