Water Leak Detection and Repair
Finding a hidden water leak before it costs you a floor, then repairing it. Slab leaks, wall leaks and yard line leaks, located with listening gear and pressure testing instead of guesswork.
Water leak detection is the work of finding water that is escaping somewhere you cannot see, and leak repair is fixing it once we know exactly where it is. The finding is the hard part. A leak under a slab or inside a wall can run for weeks before it shows. All Plumbing Services has done this work since 2013, and we locate first, then open.
What is water leak detection?
It is locating a hidden leak without demolishing the house to find it. We isolate the system and watch the meter, pressure test sections of pipe to narrow down which run is losing water, and use listening equipment to hear water escaping under concrete or behind finish. The goal is a small, confident opening in one place rather than a wall taken apart hoping to get lucky.
Signs of a hidden water leak
A water bill that jumps with no change in habits is the classic one. Others: a warm patch on a floor, the sound of running water when every tap is off, a musty smell, paint bubbling low on a wall, or a section of yard that stays green in dry weather. Any one of them is worth a look before it turns into a repair of the finishes too.
What is a slab leak?
A slab leak is a leak in a water line running under or inside the concrete foundation. Many Southern California homes are built slab on grade with the supply lines cast into or beneath the slab, which is why slab leaks are a regional problem rather than a rare one.
Because the water has nowhere obvious to go, it shows up as a warm floor, a high bill, or damage a long way from the leak.
How do we find a leak without tearing up the house?
We shut everything off and watch whether the meter still moves, which proves the leak is on the supply side. Then we isolate sections and pressure test to narrow the run. Then we listen. Electronic listening gear picks up the sound of pressurized water escaping through concrete or drywall. Only when we can point at a spot do we open anything up.
Water leak repair: your options once we find it
Once the location is known there is usually more than one honest way to fix it. A single failed section can often be cut out and repaired in place. Where a line under concrete is difficult to reach, rerouting that one run above the slab can be less disruptive and less expensive than breaking concrete. We explain the choices and what each one means for your floors before you pick.
Leaks under a slab, in a wall, or out in the yard
Where the leak sits changes the job completely. A wall leak means opening drywall and repairing a joint or a section of pipe. A slab leak means either breaking concrete at one point or rerouting the line. A yard leak on the service line between the meter and the house means digging, and it is often the reason for a wet patch with no indoor symptom at all.
What to do the moment you think you have a leak
Find your main shut-off valve and know where it is before you need it. If water is actively running where it should not be, shut the main off and call us at (818) 987-6284. If the leak is slow and hidden, take a meter reading with everything off, wait an hour, and read it again. If it moved, water is going somewhere.
Best Water Leak Detection and Repair in Chatsworth
Slab on grade construction is common across Chatsworth and the West San Fernando Valley, and homes built that way are where slab leaks show up. Older supply piping in that same housing is why weak flow and hidden leaks often turn up in the same house.
When the water problem turns out to be a drain rather than a supply line, that is drain and sewer work instead, and we will tell you which one you actually have.

FAQ
Water Leak Detection and Repair, common questions
Where can I find water leak detection near me in Chatsworth?
All Plumbing Services finds and repairs hidden water leaks in Chatsworth and the nearby West Valley. We are licensed, bonded and insured, CSLB #985835. Call (818) 987-6284 and tell us what you are seeing, whether that is a high bill, a warm floor or a damp patch. Ask for a free estimate before any work begins.
Do you charge for leak detection on top of the repair?
Detection and repair are two different pieces of work, and how they are billed depends on what the job turns into. What we will not do is start opening walls or floors on a guess and bill you for the search. We give you a free estimate first, and you know what the location work involves before we begin.
How long does it take to find a hidden water leak?
Most locations take one to three hours. A simple meter test plus a pressure isolation often narrows it fast. A slab leak under finished flooring, or a house with several possible runs, takes longer because each section has to be ruled out. We tell you what we have ruled out as we go, so you are never paying for silence.
Are you insured if a leak repair opens up my wall or floor?
Yes. All Plumbing Services is licensed, bonded and insured, CSLB #985835, and you can verify that number on the California CSLB website. Leak repair is the work most likely to involve opening finished surfaces, so being properly insured matters here more than on almost any other plumbing job. We also tell you what we plan to open before we open it.
Can a water leak raise my bill without anything showing?
Yes, and that is the most common way a slab leak announces itself. Water escaping under concrete has somewhere to go, so nothing appears indoors while the meter keeps turning. A bill that climbs with no change in how you use water is worth a meter test. It costs you nothing to check and it can save a floor.
Is a small drip worth fixing right away?
Yes, for two reasons. A slow leak is still constant, so it adds up on the bill month after month. More importantly, water in a wall or under a floor causes damage long before you would ever notice the leak itself. Small now is cheap. The same leak found later usually comes with finish repair attached to it.
