Before agreeing to a sewer replacement that means trenching your garden, it is worth finding out whether you need it at all.
Where it genuinely applies
The original Hanahan streets have clay and cast iron laterals old enough to be failing, running under settled lawns, driveways and mature trees. Lining creates a new pipe inside the old one through access points that already exist, so what is above ground stays as it is. It also removes the joints roots were getting in through, which is why it lasts rather than delaying the problem.
Where you probably do not need it
If your home is in Tanner Plantation or one of the other newer neighbourhoods, the pipe is modern PVC and nowhere near the end of its life. A blockage there is something to clean out. If lining has been suggested for a house that new, ask to see the camera footage first.
Digging here is messier than most places
Low, flat ground with a high water table means a trench fills with water and needs proper shoring. Putting the ground back afterwards becomes its own job, which is part of why lining is often the better answer here.
When it cannot be done
If a pipe has collapsed, or sagged so badly it holds water, there is nothing sound left to line against. Better you hear that after we look than partway through.
