Referral service, not a contractor. Total Home Cost does not perform repairs. We may be paid if you hire a provider through a partner link. Always confirm the provider's license and get a written estimate. How this works
Main water line leak repair cost (2026)
| Main line water leak repair (Angi) | $600–$4,500 |
| Leaking pipes, typical (Angi) | $175–$550 |
Confirm it first
Use the meter test: if the meter still moves with the house shutoff closed, the leak is likely between the meter and the house.
Cost drivers
- Depth and length of the line, and what's above it (driveway, landscaping)
- Spot repair vs. full replacement
- Permits and street or sidewalk work
Know where your shutoff is (find and test it), and check pressure while you're at it (high pressure).
