The cost to fix a busted underground pipe varies widely, depending on what kind of pipe it is, how deep it sits, how long a section needs repair, and how difficult it is to access. For a short, simple spot repair with easy digging, you might pay several hundred to a couple of thousand dollars, including labor and basic restoration. If a long section of water or sewer line must be replaced, costs often move into the low to mid thousands, especially if the pipe runs under driveways, sidewalks, or landscaping that must be removed and rebuilt. Some plumbers charge per linear foot for underground work, and trenchless methods like pipe lining or pipe bursting can sometimes reduce surface damage, though the per‑foot price can still be significant. Getting multiple written quotes is usually the best approach.
