After a backup is cleared, a camera inspection reveals why it happened. It might be grease, roots, a broken section or an object stuck in the line. Knowing the cause helps you avoid repeat backups. We often recommend an inspection after any main line clearing.
Belly and Offset Detection in Williston, ND
A belly is a low spot where the pipe has sagged and holds water and waste. Offsets happen when pipe sections shift out of alignment, often because of soil movement. Heavy, expansive clay soils are common in North Dakota, and they swell and shrink with moisture and frost, stressing foundations and buried pipe. The camera shows these defects clearly, and we mark their location for repair.

A standard residential sewer camera inspection usually costs $150 to $400. Inspections that require clearing first or roof access may cost more. Compared with sewer repairs that can run $3,000 to $15,000 or more, an inspection is a small investment. It can save you from buying a home with a hidden sewer problem.
