When this service may be relevant

Not every hidden leak is under the slab. Similar symptoms may come from fixtures, walls, water heaters, irrigation, or drains. Diagnosis helps distinguish the source.

What to discuss with a provider

Request a clear explanation of the affected line, proposed method, testing after repair, permit considerations, and written restoration scope.

Before approving work, request a written scope that explains testing, access, materials, expected disruption, concrete or flooring restoration, exclusions, and the price basis. Permit needs can depend on the work and local requirements.

Cost and planning considerations

Costs vary with the source and location of the leak, diagnostic steps, pipe material, access, labor, and finish restoration. There is no single price that applies to every property. Compare written estimates on the same scope rather than comparing only a headline number.
