Old galvanized steel, corroded copper, or failing polybutylene lines eventually turn into a bigger job than a single patch can fix. Repiping means replacing some or all of a home's water supply lines, usually with PEX or copper, rather than repairing one leak at a time. Pipe repair is the smaller-scale version: cutting out a corroded or burst section, fixing a pinhole leak, or addressing a slab leak without touching the rest of the plumbing. We've listed 7 businesses in West Columbia that handle this kind of work, from single-leak fixes to whole-house repipes.
What separates a good job from a bad one usually comes down to a few things: whether the contractor actually diagnoses the cause of the leak instead of just patching the symptom, whether they can work with your home's construction (slab, crawlspace, or wall cavities) without unnecessary demolition, and whether they stand behind the repair with a real warranty on both materials and labor. Ask for a written estimate that spells out pipe material, how much drywall or flooring will be opened up, and who handles patching afterward.
Our scoring weighs how each company handles licensing, insurance, response time, and the pattern of feedback across real customer reviews, not just a star average.
