How do I know if I actually need repair or if cleaning is enough?
If cleaning restores flow and the camera shows a structurally sound pipe with no cracks, offsets, bellies, or root entry points, cleaning is enough. If cleaning restores flow but the camera shows structural damage — the pipe is cracked, offset, collapsed, bellied, or deteriorated — then cleaning is buying time, not fixing the problem. The blockage will return because the pipe is creating it. For the specific warning signs, see Sewer Line Repair: Warning Signs Your Pipe Needs More Than Cleaning.
