Frequently Asked Questions
About Slab Leaks
1. What is a slab leak?
A slab leak is a water or sewer line leak located under your home’s concrete foundation. These pipes can crack, corrode, or burst, causing water to seep into the soil beneath your home.
2. What are the most common signs of a slab leak?
Typical symptoms include:
- High water bills
- Warm spots on the floor
- Damp carpet
- Cracks in walls or flooring
- Low water pressure
- Running water sounds
- Water pooling around the foundation
If you notice 2 or more signs, you likely have a slab leak.
3. How much does slab leak repair cost in Dallas?
Slab leak repair in Dallas typically costs:
- Leak detection: $325 flat
- Jackhammer repair: $3,700
- PEX reroute: $3,700
- Tunneling repair: $4,200 + $250/ft
Your exact cost depends on the leak’s location and the best repair method.
4. Does homeowners insurance cover slab leaks?
In most cases:
✔ Insurance covers the access to the leak (e.g., jackhammering or tunneling)
✔ Insurance may cover water damage caused by the leak
✔ Insurance does not always cover repairing the pipe itself
Coverage varies by policy, but we help guide homeowners through the process.
5. What causes slab leaks in Dallas homes?
Common causes include:
- Shifting clay soil
- High water pressure
- Corroded copper pipes
- Hot water line deterioration
- Poor construction practices
- Abrasion against concrete
Texas soil conditions make slab leaks more common than in many states.
6. How long does slab leak repair take?
Repair timelines vary:
- Leak detection: same day
- Jackhammer repair: same day
- PEX reroute: 1 day
- Tunneling repair: 1–2 days
We work efficiently while ensuring high-quality repairs.
7. Do you have to break my floors to repair a slab leak?
Not always.
Jackhammering is only used when the leak is directly beneath the floor.
But most repairs can be done without breaking interior flooring using tunneling or PEX reroutes.
8. What is the most permanent fix for slab leaks?
The most permanent solution is usually a PEX reroute.
It removes pressurized pipes from beneath the slab entirely, preventing future slab leaks.
9. How do you detect a slab leak?
We use:
✔ Acoustic listening equipment
✔ Thermal imaging
✔ Pressure testing
✔ Tracer gas detection
✔ Sewer camera inspection
These tools allow us to pinpoint leaks accurately — without unnecessary demolition.
10. Are slab leaks dangerous?
If ignored, slab leaks can cause:
- Foundation movement
- Mold growth
- Structural damage
- Increased utility bills
- Major water damage
Fast action prevents expensive repairs.
11. Can I ignore a small slab leak?
No.
Even a slow leak can cause thousands of dollars in foundation damage and mold growth. Slab leaks always get worse over time.
12. What’s the difference between a slab leak and a foundation leak?
A slab leak refers to a plumbing leak under the slab.
A foundation leak refers to water causing structural movement or cracks.
Slab leaks often cause foundation leaks — and we repair both.
13. How do I turn off the water if I suspect a slab leak?
Locate the main water shutoff valve, usually:
- Near the water meter box
- In the front yard
- Against an exterior wall
- In a garage in newer homes
Turning off water can slow the leak and prevent further damage.
14. Are hot water slab leaks more common?
Yes — hot water lines tend to deteriorate faster, often due to expansion, soil movement, and pipe corrosion.
Warm floor spots are a major indicator.
15. Can slab leaks come back after repair?
If you repair the specific pipe section, yes, future leaks can occur in other areas.
If you install a PEX reroute, the chance of future slab leaks is almost zero.
16. Do you offer financing?
If you repair the specific pipe section, yes, future leaks can occur in other areas.
If you install a PEX reroute, the chance of future slab leaks is almost zero.
