Clearing the blockage is half the job. Finding out why it happened is the other half.
Quick answer: Drain cleaning starts by distinguishing one slow fixture from a shared drain problem, so the proposed work addresses the affected part of the line. Licensed plumbing subcontractors perform the plumbing work and pull their own required trade permits.

Charleston has two conditions that make recurring blockages more common than they might be elsewhere. Mature live oaks put substantial root systems into exactly the depth range where older clay and cast iron laterals run, and roots find joints. And the region’s high water table means groundwater intrusion at those same failed joints, which carries silt into the line.
The distinction worth insisting on is between clearing and diagnosing. Cabling a line restores flow. If the same line blocks again in three months, the cable did not address the cause, and a camera inspection is what tells you whether you are dealing with roots, a bellied section, or a broken joint.

Because clearing a blockage and fixing its cause are different jobs. If a line re-blocks within a few months, something structural is usually behind it — root intrusion at a joint, a section that has settled and holds water, or a partial collapse.
A camera inspection answers it in an afternoon; repeated cabling does not.
They are generally a poor trade. They can clear a light soft blockage, and they do nothing at all against roots or a structural fault.
On older cast iron and on some plastics, repeated use is hard on the pipe, and the residual chemical is a hazard for whoever opens the line afterwards.
Routinely. The live oaks that make these neighbourhoods what they are have root systems that reach exactly the depths older laterals run at, and roots exploit any joint that leaks even slightly.
It is one of the most common causes of recurring blockage in the older parts of the county.
