Repiping means replacing a home's water lines, either whole-house or in sections, because the existing pipes have corroded, are leaking repeatedly, or are made of an outdated material like galvanized steel or polybutylene. Pipe repair is the smaller-scale version: fixing a burst line, patching a pinhole leak, cutting out a corroded section, or reworking a bad joint. In older parts of West Columbia, a lot of this work traces back to galvanized supply lines that have been in the ground or walls for 40-plus years and have finally rusted through from the inside.
Before hiring, ask what pipe material they'll use (PEX and copper are the common choices, each with tradeoffs on cost and longevity), whether they pressure-test the system after the work, and how they handle drywall or slab access if the job requires cutting into walls or concrete. A written estimate that separates labor, materials, and any patch-up work is worth asking for up front, since repiping jobs can run from a single-room repair to a full-house project spanning several days.
