Slab Leak Repair in Texas
Water bill spiked? Hot spots on the floor? We detect and repair slab leaks under concrete foundations using tunneling or epoxy lining methods.
What Is Slab Leak Repair?
Slab leak repair addresses leaks in the water pipes that run beneath your home's concrete slab foundation. Nearly all Texas homes are built on slab foundations, and the hot and cold water supply lines typically run through or under the concrete. When these pipes develop leaks, the water seeps into the soil beneath the slab, causing foundation erosion, flooring damage, mold growth, and dramatically increased water bills.
Detection is the first step. Electronic leak detection equipment — including acoustic amplifiers, thermal imaging cameras, and pressure isolation testing — pinpoints the exact location and depth of the leak without tearing up your floor. Once located, repair options include direct access (jackhammering through the slab to reach and repair the pipe), tunneling (digging under the foundation from outside to access the pipe without breaking the interior floor), and rerouting (abandoning the leaking line and running a new pipe through the attic or walls to bypass the slab entirely).
The best repair method depends on the leak location, pipe material, overall condition of the under-slab plumbing, and your home's layout. If one pipe under the slab has leaked, others in the same system are often in similar condition — in these cases, rerouting or full repipe may be more cost-effective than repeated spot repairs.
Slab leaks are one of the most common and expensive plumbing problems in Texas. The combination of slab foundations, expansive clay soils, hard water, and copper pipes creates conditions that accelerate pipe deterioration. Cities throughout Texas — from Houston and Dallas to small towns across the state — see high volumes of slab leak calls.
Signs You Need Slab Leak Repair
If you notice any of these symptoms, it's time to call a licensed plumber for professional assessment.
- ⚠Unexplained spike in your water bill — even a small slab leak can waste thousands of gallons monthly.
- ⚠Hot spots on the floor — a hot water line leak warms the slab above it.
- ⚠Sound of running water when all fixtures are off.
- ⚠Damp carpet, warped flooring, or mold smell without a visible leak source.
- ⚠Cracks in the foundation, walls, or floor — ongoing water erosion undermines the slab.
- ⚠Water meter running when all fixtures are turned off.
Common Causes and Why This Happens
Understanding what causes the problem helps you make an informed decision about the best repair approach.
Copper pipe corrosion from aggressive soil chemistry beneath the slab — pinhole leaks develop over years.
Thermal expansion stress on hot water lines running through concrete — joints fatigue and fail.
Abrasion from pipes rubbing against concrete or gravel as they expand and contract.
Poor original installation — insufficient protection around pipe penetrations through the slab.
Ground shifting from expansive clay soil putting lateral pressure on pipe runs.

Surface restoration plan for any concrete, tile, or flooring disturbed.
How Much Does Slab Leak Repair Cost in Texas?
| Low | Average | High |
|---|---|---|
| $500 | $2,500 | $6,000+ |
Prices vary based on the specifics of each job. We provide a detailed, itemized estimate on site before any work begins — the price you approve is the price you pay.
Factors That Affect Cost
- •Repair method — direct access is cheapest; tunneling and rerouting cost more but cause less interior disruption.
- •Leak location — center-of-home leaks require more access work than edge leaks.
- •Pipe condition — if the overall system is deteriorating, rerouting or repiping is recommended over spot repair.
- •Flooring type — tile, hardwood, and concrete require different restoration approaches after access.
- •Detection cost — typically $200-500 and billed separately from the repair.
Benefits of Professional Slab Leak Repair
Stops hidden water waste that can reach 50-100+ gallons per day.
Prevents ongoing foundation erosion that leads to structural damage and expensive foundation repair.
Professional detection limits the access area — saving thousands vs. exploratory demolition.
Reroute option permanently eliminates the under-slab pipe entirely, preventing future slab leaks on that line.
Expert Tip
If your water bill has increased significantly without a change in usage, or you notice a warm spot on a tile or concrete floor, don't wait. A slab leak that runs for weeks can erode enough soil beneath the foundation to cause visible cracking in walls, doors that won't close properly, and eventual foundation repair bills in the $5,000-$20,000 range.

How do you detect a slab leak without tearing up my floor?▼
We use electronic acoustic sensors that amplify the sound of water escaping under pressure, thermal imaging that detects temperature differences from leaking water, and pressure isolation testing to narrow down which line is leaking.
What causes slab leaks in Texas?▼
The combination of copper pipes, hard water, expansive clay soils, and thermal expansion creates conditions that accelerate pipe deterioration under Texas slab foundations.
Should I repair the slab leak or reroute the pipe?▼
If only one pipe has leaked and the rest are in good condition, spot repair is appropriate. If the system is old or multiple leaks have occurred, rerouting through the attic eliminates the problem permanently.
Does homeowners insurance cover slab leak repair?▼
Many Texas policies cover the resulting water damage but not the plumbing repair itself. Some policies include an optional slab leak rider. Check with your insurer.
How long does slab leak repair take?▼
Detection takes 1-3 hours. Spot repair via direct access takes 1 day. Tunneling takes 1-2 days. Rerouting typically takes 1-2 days.
