LEAK DETECTION / UNDER-SLAB PIPING
SUSPECT A SLAB LEAK? CONFIRM THE SOURCE.
A leak beneath a concrete floor can be difficult to locate from surface symptoms alone. We assess whether plumbing is implicated, explain the evidence and access involved, and compare repair approaches for the confirmed line.
LEAK DETECTION / SPECIALTY SERVICE
UNDERSTAND THE ISSUE
A slab leak is a leak in plumbing routed beneath or through a concrete slab. Warm flooring, a damp area, sound of moving water, or water use that continues when fixtures are off can raise the question, but none proves the pipe location by itself. Irrigation, exterior water, drainage, and other sources should also be considered. Confirming the source matters because a repair method depends on the pipe, route, and access conditions.

WHAT WE'LL CHECK
We review the home’s symptoms, accessible shutoffs, nearby fixtures, visible supply or return paths where relevant, and any prior repair history. The assessment determines whether signs support an under-slab plumbing leak and what further confirmation or access may be required. We explain the likely repair boundaries before discussing a reroute, an accessible repair point, or another option. No single surface symptom can establish the final method or total scope.
A localized repair can be considered when the failure point and access are sufficiently clear and the surrounding pipe condition supports that approach.
A reroute may be considered when opening the slab is impractical or when the line route and property layout support a new path. The route, connections, and finish impact need evaluation.
ESTIMATE DETAILS
The cost to fix a slab leak varies with diagnosis, access, and the chosen repair. An estimate should account for:
Request a free estimateThe amount of investigation needed and confidence in the leak area affect how the repair can be planned.
Direct access to the failed pipe and an alternate route have different labor, material, and connection requirements.
Slab cutting, flooring removal, drying, and finish restoration may be separate from the plumbing repair.
WHAT TO EXPECT
We'll explain what we found, what the work involves, and the price before you decide. An online request starts the conversation; we'll confirm the appointment with you.
Describe where warmth, moisture, or sound occurs and whether the issue changes with water use.
We review accessible lines and determine what diagnosis or access is needed to confirm a slab leak.
We explain viable repair approaches, access and finish responsibilities, and an estimate before work begins.
GOOD TO KNOW
Have a question about your plumbing? These answers cover what we’re often asked.
Warm or damp flooring, unexplained water use, water sounds with fixtures off, or repeated pressure changes can be clues. Other water sources can create similar signs, so assessment is needed.
There is no reliable price from the symptom alone. Diagnosis, pipe location, access, repair method, and slab or flooring restoration all affect the estimate.
No. The repair may involve direct access or a route that avoids the affected slab, depending on the line and property. The available options should be compared after the source is assessed.
Water that continues beneath flooring can affect materials and should be assessed promptly. A plumber can address the plumbing source; structural or finish concerns may need separate evaluation.
