Slab leak detection

Slab Leak Detection in Houston

Houston's clay soil shifts, and that movement is hard on the pipes running under your slab. A leak down there can go months without a sign, then show up as a spiked water bill, a warm spot on the floor, or a crack in the foundation. We use electronic detection to pinpoint the leak — no guesswork, no tearing up floors to go looking — and where it helps, hydrostatic testing to confirm it's under the slab.

  • Electronic detection pinpoints the leak
  • Hydrostatic testing confirms under-slab leaks
  • Under-slab tunneling — no jackhammered floors

We locate the leak before we open the floor

A slab leak can quietly run for months — a spiked bill, a warm patch on the floor, a meter that ticks with every tap off. We use electronic detection and hydrostatic testing to find exactly where the pipe is leaking under the slab, so any repair is aimed at one spot instead of tearing up the whole floor to hunt for it.

  • Electronic detection that pinpoints the leak location
  • Hydrostatic testing to confirm under-slab leaks
  • Camera inspection of the line where it helps
  • Full-home walkthrough — fixtures, meter, and supply lines
  • Under-slab tunneling to repair without breaking your floors
  • Early detection that heads off foundation and mold damage
  • A written estimate and repair plan once we find it
How it works

How it works

1

Walk the home

We check fixtures, under sinks, irrigation, and your water meter for the tell-tale signs — a meter creeping with no water running, a warm floor, a musty smell.

2

Pinpoint the leak

Electronic detection locates the leak under the slab, and hydrostatic testing confirms it, so we know exactly where to work before anything is opened up.

3

Lay out the repair

You get a written estimate and a plan. For under-slab leaks that usually means tunneling in from outside, not jackhammering your floors.

4

Fix it for good

We make the repair and, where the pipe is failing throughout, talk honestly about whether a repipe is the smarter long-term fix.

“Could not recommend Lance more for plumbing needs. We used Lance for a whole house repipe, new water heaters, and toilet replacement. From the very beginning Lance was responsive, informative, and easy to work with. He explained the job thoroughly, gave us a very competitive quote, and provided a great experience from start to finish. Highly recommend!”

Questions for us

Slab Leak Detection FAQ

How do I know if I have a slab leak?
Watch for a water meter that runs when everything's off, a jump in your bill, a warm or damp spot on the floor, the sound of running water, cracks in the floor or foundation, or a musty smell. Any of those is worth a look.
How do you find a slab leak without tearing up my floors?
Electronic detection lets us locate the leak under the slab from the surface, and hydrostatic testing confirms it. We know where the problem is before we open anything up.
Why are slab leaks common in Houston?
Our clay-rich soil expands and contracts and shifts foundations, and that stress cracks the pipes running underneath. Add corrosion on older pipe and the occasional hard freeze, and slab leaks are a Houston regular.
Can you fix the leak without breaking my slab?
In most cases, yes. We tunnel in from outside to reach the pipe, so your floors, walls, and appliances stay put and you can keep living in the house while we work.
Should I repair the slab leak or repipe?
If it's a single failure, a targeted repair does it. If the pipe's corroding throughout, one leak is often the first of several — that's usually when a whole-home repipe makes more sense than chasing leaks one at a time. We'll lay it out and let you decide.
