A sewer scope inspection utilizes a specialized camera system to visually inspect the lateral sewer line from the main cleanout to the city main sewer line. It is used to identify potential defects in the sewer line that may compromise the integrity or serviceability of the building sewer. 

Common defects that cannot be found with a regular home inspection include, separated joints, root intrusion, cracks, corrosion, crushed pipes, blockages, and belly or sags.

With the cost of a typical sewer lateral replacement averaging $7,000-$15,000, it makes sense to add the service to your home inspection.
