How Do I Know If I Have a Slab Leak in My Los Angeles Home?
Slab leaks are one of the most serious and most common plumbing problems in Los Angeles. The city has thousands of homes built between 1950 and 1975 with copper water lines embedded directly in the concrete slab foundation. These pipes corrode over time, developing pinhole leaks that can go undetected for months while causing significant damage beneath your home.
Signs You May Have a Slab Leak
High water bill: An unexplained increase in your water bill — especially if nothing has changed in your usage — is often the first sign of a slab leak.
Warm or hot spots on the floor: A warm patch on your floor, especially on a concrete or tile floor, often indicates a hot water line leak beneath the slab.
Sound of running water: If you can hear water running when all fixtures are off, you likely have an active leak somewhere in the system.
Cracks in flooring or walls: As a slab leak erodes soil beneath the foundation, the concrete can shift and crack flooring, tiles, and walls.
Mold or mildew odor: Moisture from a slab leak can promote mold growth inside walls and beneath flooring without any visible water.
Water meter moving with everything off: Shut off all water inside and outside your home and watch the water meter. If it continues to move, you have an active leak.
