Leak Detection in Fountain Valley, CA
The expensive leaks hide in walls, under the slab, or underground. We pinpoint them with non-invasive equipment, so the only thing opened is the spot that needs the repair.
Some leaks announce themselves. The expensive ones hide, inside a wall, under the slab, or underground between the meter and the house, quietly running up your bill and damaging the structure. We locate hidden leaks precisely with non-invasive equipment, so the only thing that gets opened is the spot that actually needs the repair.
The leaks that hide in FV homes
Fountain Valley's aging copper and galvanized supply lines, run through slabs and walls in homes now half a century old, give hidden leaks plenty of places to start. The common ones:
Slab leaks
Supply lines under the concrete slab, the most common hidden leak in the city's tract homes. We cover these in depth on our slab leak page.
In-wall leaks
A pinhole in a copper line inside a wall can run for weeks before a stain appears, feeding mold behind the drywall.
Underground service-line leaks
The line between the meter and the house can leak underground, showing up only as a high bill and a meter that never stops.
Drain and sewer leaks
Leaks on the waste side hide under floors and in walls, often signaled by smell or staining rather than a high water bill.
How we find a hidden leak
Finding a leak without tearing up the house takes the right tools used in the right order. We confirm a leak exists by isolating the system and watching the meter, then narrow it down with several methods. Acoustic equipment listens for the sound of escaping water through slab and wall. Thermal imaging spots the temperature difference a hot-water leak creates behind a surface. Pressure testing isolates which line is losing water, and moisture meters confirm where it is collecting. Used together, they turn a whole-house mystery into a marked spot on a wall or floor.
Why precise location saves money
The cost of fixing most leaks is small next to the cost of finding them the wrong way. Opening drywall or breaking slab on a hunch can mean several openings before you find the leak, and several repairs afterward. Locating it first means one access cut, one repair, one patch. That precision is the whole point of leak detection, and it is why we invest the time to pinpoint before we open anything.
Reading your water bill and meter
You can catch many hidden leaks early yourself. If your water bill climbs with no change in habits, that is worth investigating. The simplest test: turn off every fixture and water-using appliance, then check the meter. If the dial is still moving, water is escaping somewhere between the meter and your fixtures. A meter that creeps with the house shut off is the clearest sign of a hidden leak, and a good reason to call before the damage grows.
What leak detection costs
A leak detection visit in central OC commonly runs about $150 to $400 depending on how involved the search is. That fee buys you a precise location and an honest diagnosis, and when it leads into a repair we are doing, we tell you up front how it factors in. Finding the leak correctly is what keeps the repair small.
Frequently asked questions
How do I know if I have a hidden leak?
Common signs are a water bill that climbs with no change in usage, a musty smell, staining on walls or ceilings, the sound of running water when everything is off, and a water meter that keeps moving after you shut off the house. Any of these is worth a call.
How do you find a leak without tearing up my home?
We use non-invasive tools in sequence: acoustic listening for escaping water, thermal imaging for the temperature signature of a hot-water leak, pressure testing to isolate the failing line, and moisture meters to confirm where water collects. Together they pinpoint the spot before anything is opened.
Can I check for a leak myself?
Yes. Turn off every fixture and water-using appliance, then watch the water meter. If the dial keeps moving, water is escaping somewhere between the meter and your fixtures, which points to a hidden leak worth investigating.
