What moves the price
- Size of the system — a larger tank and drain field take longer to inspect and need more materials if repairs are needed.
- Condition of the septic tank — cracks or broken baffles found during the inspection turn a check into a repair job.
- Extent of repairs needed — replacing a baffle is a small job, while repairing a failed soakaway means digging and new pipework.
- Access and depth — a septic tank buried deep or in a hard-to-reach spot needs more digging before inspection or repair can start.
