The visit is scoped for one job: clean the main sewer run and verify the result on camera. The technician accesses the line through the cleanout, assesses the buildup type, selects the cleaning method, cleans the full affected run, and cameras the result - all in a single trip. There is no preliminary diagnostic visit. There is no scheduling a second appointment for the camera. Everything needed to clean the sewer line and document its condition happens in the same visit.
The cleaning method is determined by what the line contains. Soft blockages - paper, waste, light sludge - may respond to cabling. Wall-bonded buildup - hardened grease, root mass, mineral scale, compacted sediment - requires jetting at wall-contact pressure to strip the material from the pipe interior. The technician makes that determination on site based on what the cleanout reveals and what the line produces during the initial clearing. Both methods are available on the truck. The right one is selected for the job, not predetermined before arrival.
The camera pass after cleaning is what makes this a verified service instead of a blind clearing. The footage shows the pipe walls clean, the joint conditions, any root entry points that were hidden under the buildup, grade issues, and structural defects. If the pipe is healthy and the cleaning was the complete fix, you know. If the footage shows something that needs follow-up - a cracked section, a belly, heavy root damage at a joint - you know that too, with footage, before the truck leaves. Either way, the visit produces a definitive result.
