Slab Leaks in San Diego: Signs, Risks & Detection
Slab leaks are common in older San Diego homes. Learn the warning signs, what causes them, and how professional leak detection saves thousands.
Common Causes
- Corrosion of copper pipes embedded in the concrete slab — accelerated by San Diego soil chemistry
- Abrasion from pipes rubbing against concrete as the slab shifts
- High water pressure causing stress fractures in pipe joints
- Poor original installation with pipes kinked or improperly supported
- Expansive clay soils in East County causing slab movement
- Age — homes built before 1980 are at highest risk
Warning Signs
- Unexplained spike in your water bill — even $30–$50/month increase
- Sound of running water when all fixtures are off
- Warm or hot spots on tile or hardwood floors
- Cracks appearing in walls, floors, or foundation
- Mold or mildew smell coming from floors or baseboards
- Low water pressure throughout the house
- Wet or damp carpet or flooring with no visible source
