Written by Steven Shipler, CEO, Texas Licensed Master Plumber, Registered Master Plumber, MBA. Texas License #45825.
Before you hire anyone to cut concrete, tunnel, reroute, or repair an under-slab leak, get the leak located and documented. With Lone Star Leak Locators, you receive a Certified Master Plumber Report from a licensed Master Plumber in Texas: Texas License #45825.
The Short Answer
Yes. If you need an under-slab leak repair plumber in North Dallas, Plano, Richardson, Allen, McKinney, Frisco, or Collin County, the first step should be professional leak detection before repair.
Under-slab leaks are expensive because the leak is hidden below the concrete foundation. If the plumber guesses wrong, the homeowner may pay for unnecessary flooring removal, concrete cutting, tunneling, cabinet removal, wall repairs, or pipe work that does not solve the real problem.
Lone Star Leak Locators specializes in slab leak detection, water leak detection, pool leak detection, gas leak detection, and underground leak locating. We help homeowners understand what is leaking, where the evidence points, and what repair options make sense.
Why Under-Slab Leaks Are Hard to Diagnose
An under-slab leak may be a pressurized hot water line, cold water line, sewer line, drain line, gas line, pool line, irrigation line, or exterior water service line. The symptoms can overlap.
A wet floor does not automatically mean the water line is leaking directly under that exact spot. Water can travel through soil, cracks, pipe chases, vapor barriers, wall cavities, or flooring materials before it appears.
I have seen homeowners think the leak was in one room, only for testing to show the problem was somewhere else. That is why the best under-slab repair starts with diagnostics, not demolition.
Common Signs You May Have an Under-Slab Leak
- Sudden increase in your water bill
- Water meter movement when all fixtures are off
- Hot spots in flooring
- Damp carpet or wet flooring
- Low water pressure
- Foundation cracks or settling
- Mold or mildew odors
- Sound of water running when nothing is on
- Water appearing near baseboards
- Recurring drain backups
- Sewer smell inside the home
- Soft spots, lifting floors, or loose tile

What to Ask Before Hiring an Under-Slab Leak Repair Plumber
- Will you locate the leak before cutting concrete?
- Will I receive a written report?
- Are you a licensed Master Plumber in Texas?
- Is the leak on the hot water line, cold water line, sewer line, drain line, gas line, pool line, or service line?
- Will you pressure test the system?
- Will you use acoustic listening equipment?
- Will you check whether sewer or drain issues are involved?
- What repair options are available besides cutting the floor?
- Is rerouting possible?
- Will permits or inspections be required?
- What restoration work is excluded?
- What warranty applies?
A good under-slab leak plumber should be able to explain the evidence, not just sell the repair.
Under-Slab Leak Repair Options
| Repair Option | What It Means | When It May Make Sense |
|---|---|---|
| Spot Repair | Open the area and repair the failed pipe section. | When the leak is isolated and access is reasonable. |
| Water Line Reroute | Bypass the leaking under-slab line with a new route. | When cutting the slab is too destructive or the line is high risk. |
| Tunnel Repair | Access the pipe from beneath the foundation. | When interior finishes should be protected. |
| Sewer Line Repair | Repair or replace failed drain or sewer pipe under the slab. | When camera evidence shows bellies, breaks, offsets, or sewer leaks. |
Tools and Equipment Used
- Acoustic leak listening equipment: Used to listen for pressurized water escaping beneath concrete, walls, floors, and underground piping.
- Pressure isolation testing equipment: Used to determine whether the hot water, cold water, gas, pool, or plumbing line is losing pressure.
- Thermal imaging, moisture mapping, and electronic locating tools: Used to identify heat patterns, moisture movement, and likely leak pathways.
When sewer or drain symptoms overlap with the leak concern, additional diagnostics may include RIDGID SeeSnake sewer camera equipment, electronic line locating, and sewer inspection tools.
Why a Certified Master Plumber Report Matters
A recommendation is helpful. A written report is stronger. Lone Star Leak Locators provides a Certified Master Plumber Report from Steven Shipler, Texas Licensed Master Plumber, Registered Master Plumber, MBA, Texas License #45825.
This report helps document the symptoms, testing performed, likely leak area, system involved, and next recommended repair step. That matters for homeowners, second opinions, insurance conversations, real estate transactions, and repair planning.
If someone recommends an under-slab leak repair plumber, ask whether that plumber will give you written findings before the repair begins.

15 Frequently Asked Questions
1. What is an under-slab leak?
An under-slab leak is a hidden leak below the concrete foundation. It may involve a water line, sewer line, drain line, gas line, pool line, or service line.
2. Should I repair the slab leak before leak detection?
No. The leak should be tested and located before repair begins to reduce unnecessary demolition and wrong-area repairs.
3. Will I receive a Certified Master Plumber Report?
Yes. Lone Star Leak Locators provides a Certified Master Plumber Report from Steven Shipler, Texas License #45825.
4. Is a sewer scope inspection really necessary?
It may be necessary when symptoms could involve sewer or drain issues instead of only a pressurized water line leak.
5. How long does a sewer scope inspection take?
Many sewer scope inspections take about 30 to 90 minutes depending on access, line length, and what is found.
6. Will I receive a video of the inspection?
When a sewer camera inspection is performed, video evidence may be provided so the homeowner can see the pipe condition.
7. Can a sewer scope detect all problems?
No. A sewer scope can document visible pipe conditions, but access, standing water, obstructions, and pipe layout can limit visibility.
8. What happens if problems are found?
The next step may include locating, pressure testing, repair estimating, leak repair, sewer repair, rerouting, or additional diagnostics.
9. Is this service included in a standard home inspection?
No. Leak detection and sewer scope inspections are specialty plumbing diagnostics and are usually separate from a standard home inspection.
10. How much can sewer repairs cost?
Sewer repairs can range from smaller spot repairs to major under-slab replacement or reroute projects that may cost thousands or tens of thousands depending on the scope.
11. Can an under-slab leak damage flooring?
Yes. Water from an under-slab leak can damage carpet, wood, laminate, tile materials, baseboards, cabinets, and drywall.
12. Can an under-slab leak damage the foundation?
Yes. Ongoing water movement beneath the slab can affect soil conditions and may contribute to foundation-related concerns.
13. Is rerouting better than cutting the slab?
Sometimes. A reroute may make sense when under-slab access is too destructive or the existing line is high risk. Testing should guide the decision.
14. Can a sewer leak look like a slab leak?
Yes. Sewer leaks, drain leaks, shower leaks, and water line leaks can create overlapping symptoms. Diagnostics matter.
15. Why use a licensed Master Plumber?
A licensed Master Plumber can interpret plumbing symptoms, explain findings clearly, and provide a credible written report before repairs begin.
