This is a service North Charleston genuinely needs, which is not true of every part of the Lowcountry.
Why it fits here
Pre-war neighbourhoods have clay and cast iron laterals that are now well past their design life, and they sit under mature oaks, established driveways and small lots where open trenching is genuinely disruptive. Lining installs a new jointless pipe inside the failing one through existing access points, so the tree, the drive and the yard stay where they are.
It also solves the root problem properly
Roots enter at joints. A liner has no joints. That is why lining stops the cycle rather than delaying it, which repeated cutting does not.
Who does not need it
If your house is in Oak Terrace Preserve, Mixson or another post-1996 build, your laterals are PVC and under twenty years old. A blockage there is a cleaning problem, not a pipe failure. If lining has been proposed on a house that new, ask to see the camera footage before agreeing to anything.
When we will tell you no
A fully collapsed line, or one that has lost grade and holds water, cannot be lined — there is nothing sound to line against. Better you hear that after the inspection than halfway through a job.
