What to record
- Show the slab boundary, cover and accessible equipment without removing protective components.
- Share known water events and service records.
- Describe visible damage separately from assumptions about pump capacity or discharge suitability.
The decision to discuss
Ask who verifies the sump system before concrete work is planned. Preserve access needed for service and any specialist's requirements. A repaired slab does not certify pump performance, water control or radon protection.
Why the surrounding context matters
EPA does not recommend relying on sealing alone to reduce radon. Keep actual testing and qualified mitigation review separate from a concrete repair inquiry. Work near an existing system should preserve its verified requirements and service access.

Send the town, approximate size and access details with wide views and close-ups. Photos help us route the inquiry; we confirm the project scope before booking.
