Leak Detection & Slab Leak Repair in Glendale, CA
Professional leak detection uses acoustic listening equipment, thermal imaging and pressure testing to find hidden leaks in walls, ceilings and under concrete slabs without tearing things open first. Once it's found, the leak is repaired directly, rerouted around the slab, or fixed by repiping.

Signs you need leak detection help
- A water bill that jumps with no change in use
- The sound of running water when everything is off
- Warm spots on the floor (a possible hot-water slab leak)
- Damp drywall, bubbling paint or mold smell
- Cracks in tile or flooring
- The water meter's leak indicator spinning with all fixtures off
How do plumbers find a hidden leak without tearing out walls?
The plumber first isolates the leak to the hot side, cold side, irrigation or a specific fixture by pressure-testing the system. Acoustic sensors then pick up the sound of escaping water, and a thermal camera shows the temperature difference a hot-water leak makes. Only a small, targeted opening is needed once the leak is pinpointed.
Slab leak repair
Many Glendale, Burbank and San Fernando Valley homes are built on concrete slabs with copper lines running underneath. Over time, abrasion, corrosion and ground movement can cause pinhole leaks.
- Direct repair: open the slab at the leak, repair the pipe and patch the floor. Good for a single, accessible leak.
- Reroute: abandon the leaking line and run a new one through walls or the attic. Often less disruptive.
- Repipe: if the slab has leaked more than once, replacing the supply lines may be the better long-term fix. See repiping.
What are the signs of a slab leak?
The most common signs are a sudden rise in your water bill, warm spots on the floor, the sound of running water and damp carpet or flooring with no obvious source. If your meter's leak indicator moves with everything turned off, call for leak detection before the water damages the foundation.
Burst pipe repair
A burst pipe needs the main water shut off immediately, then a permanent repair and a check for water inside walls and ceilings. Pipes that burst once often have more weak points, especially old galvanized lines. See our 24/7 emergency plumbing page for what to do right away.

Will insurance cover slab leak repair?
Many policies cover the cost of accessing the leak and the water damage it causes, but not the pipe repair itself. Coverage varies, so call your insurer and keep the leak detection report.
How accurate is electronic leak detection?
In skilled hands, leaks can usually be pinpointed to within a small area, which keeps the repair opening small.
Can a small leak really be serious?
Yes. A slow leak inside a wall or under a slab can cause mold, rot and foundation damage long before it becomes visible.
