How it works
We run meter and pressure tests to confirm a leak exists and isolate whether it is on the hot or cold side, ruling out toilets, irrigation, and other causes first.
Using acoustic listening, electronic detection, and thermal imaging, we trace the leak to a precise location so the repair is targeted, not exploratory.
We explain what we found and lay out the viable repair approaches, such as spot repair, overhead reroute, or tunneling, with the trade-offs of each.
We complete the chosen repair, replacing or bypassing the failed section of pipe with durable materials and proper connections.
We pressure-test the repaired line, verify the meter holds steady, and confirm the area is dry before considering the job complete.
FAQ
We pressurize the repaired line and watch for pressure loss over time, then check the water meter with all fixtures off to confirm no water is moving. Moisture readings in the area complete the verification.
If pressure holds, the meter is steady, and the area stays dry, the repair is verified. This testing is a standard part of our process, not an optional extra.
Yes. The verification visit is built into the repair process, because a slab leak repair without testing leaves everyone guessing. We confirm before we close out the job.
