What Is a Foundation Leak?
A foundation leak occurs when a water line, hot water line, sewer line, or drain line beneath your home’s concrete slab begins to crack, burst, or deteriorate. These leaks saturate the soil under your foundation, causing shifting, cracking, and long-term structural damage.
Foundation leaks often go unnoticed until major symptoms appear, which is why early detection is critical.
Signs of a Foundation Leak in Your Dallas Home
If you’re experiencing any of the following symptoms, you may have a slab or foundation leak:
- Cracks in walls, floors, or ceiling
- Warm spots or wet spots on flooring
- High water bills
- Damp carpet or musty odors
- Soil erosion around the foundation
- Water pooling outside the home
- Low water pressure
- Sound of running water when fixtures are off
- Uneven or shifting floors
If 2 or more signs are present, a foundation leak is highly likely.
What Causes Foundation Leaks in Dallas Homes?
Texas is one of the most common states for foundation leaks due to:
✔ Expanding and contracting clay soil
✔ Old copper or galvanized pipes
✔ High water pressure
✔ Hot water line corrosion
✔ Poor original construction
✔ Soil movement from temperature swings
✔ Tree roots affecting under-slab pipes
As the soil shifts, buried pipes crack and begin to leak — weakening the foundation.
