Understanding slab leak detection

A slab leak is a leak in plumbing beneath or within a concrete foundation.

Questions to ask before hiring a provider

Ask who performs the work, what diagnostic evidence supports the recommendation, which permits or inspections may apply, and what the estimate includes. Request written terms for payment, restoration, and any warranty.

If the source is unclear, review water leak detection. If a slab leak is confirmed, compare under-slab pipe repair with water-line rerouting where relevant.

Availability varies by address and provider. See our Stone Oak or Leon Valley area guides for context, then confirm service coverage directly.

Frequently asked questions

Can I confirm the leak myself?

You may observe symptoms or check an accessible meter safely, but these steps cannot reliably locate every hidden leak. A qualified professional can perform suitable tests.

Should I approve a repair before the leak is located?

Ask what has been confirmed and what remains uncertain. Before invasive work, understand the proposed access method and written scope.

How do I compare estimates?

Compare diagnostic basis, access and restoration, materials, testing, timeline, and warranty exclusions. Headline prices may not cover the same work.
