Slab Leak Detection & Repair in Waco, TX

How Slab Leaks Announce Themselves
A warm spot on the floor
The classic hot-side slab leak: heated water warming the concrete from below. Pets curled up on one odd patch of tile have found more than a few of these.
The meter moves with everything off
Shut off every fixture, watch the meter. If the dial still creeps, water is going somewhere it should not — often under the slab.
A water bill that jumped without a reason
A hidden line can lose a surprising amount of water around the clock. If the bill spiked and nothing about your habits changed, take it seriously.
Damp flooring, musty smells, or the sound of running water
Moisture wicking up through the slab warps wood floors, lifts tile, and feeds mildew along baseboards long before you see standing water.
Why Slab Leaks Are a Central Texas Specialty
This region builds on slab, on clay — a combination that makes under-slab plumbing work harder here than almost anywhere.
Expansive clay flexes the slab
Blackland Prairie clay swells with rain and shrinks in drought, and the slab rides that movement. Rigid copper under the foundation takes the stress at bends and joints.
No basements, no crawlspaces
Slab-on-grade construction is the local standard, so supply lines run in or under concrete instead of somewhere a plumber can reach them. Access is the whole game.
Hard water works from the inside
Mineral-heavy water is abrasive to soft copper over decades. Pinhole leaks on hot lines under the slab are one of the most common failures we confirm.
How the Job Works
Call with what you noticed
Warm spots, meter movement, a bill spike — the symptoms help us stage the right detection equipment before we arrive.
Confirm and pinpoint
We isolate the leak with pressure testing and acoustic listening, then mark its location on your floor. Nobody should open concrete on a hunch.
Weigh the routes, in writing
Direct repair through the slab, rerouting the line overhead, or repiping if this is the third leak — each option priced and explained before you choose.
Repair, pressure-test, warranty
The repaired line is pressure-tested before anything is closed up, and the work carries our 1-year labor warranty.
What Slab Leak Repair Costs in Waco, TX
Slab leak pricing has a reputation for surprises. Ours does not, because the number is written after detection and approved before repair. What moves it:
The repair route
Opening the slab directly, tunneling beneath it, or rerouting the line overhead through walls and attic each carry very different scopes. Location and flooring decide which makes sense.
Hot side vs. cold side
Hot lines fail more often and their routing affects access. Which line failed, and where it runs, shapes the work.
One leak or a pattern
A first leak on an otherwise sound system is a repair. A second or third leak in the same aging copper is a conversation about rerouting or repiping — and we will have it honestly.

Straight Answers, Before You Call
How can I check for a slab leak myself before calling?
Turn off every fixture and appliance that uses water, then watch your water meter for several minutes. Movement with everything off means water is escaping somewhere. Feel the floors for warm patches too — a hot-side leak often gives itself away through tile. Either sign is worth a professional confirmation.
Does fixing a slab leak mean jackhammering my floor?
Not always, and this is where honest options matter. Rerouting the failed line overhead — abandoning the under-slab section entirely — often avoids opening the floor at all, and tunneling from outside the foundation can spare interior flooring. Direct access is sometimes still the right call; we price the routes side by side.
Are slab leaks connected to foundation problems?
They can run in both directions. Long-term leaks soften the clay under a foundation and contribute to movement, and foundation movement stresses the pipes into failing. If we see evidence of significant settlement during detection, we will say so — solving the plumbing while ignoring the foundation only restarts the clock.
How urgent is a suspected slab leak?
More urgent than it feels, because nothing looks dramatic yet. Every day of an active leak is water under your foundation, and clay soil responds to moisture by moving. You do not need to panic — but you should not budget it for next quarter either. Detection tells you exactly what you are dealing with.
