A lot of San Diego homes sit on concrete slab foundations, with water lines running underneath. When one of those lines springs a leak, the water has nowhere to go but into your slab, your floors, and your foundation — so catching it early matters.
What a slab leak is
It's a leak in a water line beneath the concrete foundation of your home. Older copper lines, shifting soil, and years of hard-water wear all contribute. Because it's hidden, it often shows up as symptoms long before you see water.
The 7 signs
- A spike in your water bill with no change in usage
- The sound of running water when everything's turned off
- Warm spots on the floor (from a hot-water line leak)
- Low water pressure that showed up out of nowhere
- Cracks in flooring or along walls
- Damp, warped, or discolored flooring, or a musty smell
- The water meter keeps moving with all fixtures off
A quick meter test you can do
Turn off every water fixture in the house. Find your water meter and watch the dial or leak indicator. If it's still creeping, water is moving somewhere it shouldn't be — a strong hint of a hidden leak.
Why you shouldn't wait
Slab leaks don't heal. Left alone, they undermine the foundation, ruin flooring, and invite mold. The good news: modern leak detection means we can pinpoint the spot without jackhammering your whole floor. The sooner we find it, the smaller the fix.
If two or three of these ring true, don't sit on it — give K2 a call and we'll track down whether it's a slab leak or something simpler before it turns into real money.
