Our Temecula crew finds hidden leaks under slab floors, inside walls and along the line from the meter, using pressure tests, acoustic listening and thermal imaging. Most homes here sit on concrete slabs, so we pinpoint a leak before anything is cut. The price is flat and written before work starts, and a real person answers at (951) 404-1594.

What's different about leak detection & repair in Temecula?
In a Temecula tract home, a hidden leak is most often under the floor or in the line from the meter, not inside an old wall. Finding it without tearing up tile is most of the job.
- Slab foundations
- Many Temecula homes are built on concrete slabs with the water lines running under the floor. A leak there shows up as a warm patch on tile, the sound of water running with every tap off, or a bill that climbs for no reason.
- Hard water and pressure
- Rancho California Water District's 2025 report lists its imported water at about 230 mg/L of hardness. Scale and high house pressure both work on fittings over the years, so we check the pressure regulator on every leak call; a failed one can be part of why a leak happened.
- Homes from the 1980s
- About a fifth of Temecula homes date to the 1980s, and some houses plumbed before the mid-1990s may have polybutylene supply pipe, which can fail at its fittings. A leak in a house like that is a reason to check what the rest of the pipe is made of.
How do you find a slab leak in a Temecula house?
First we confirm there is a leak with the meter and a pressure test, and separate the hot side from the cold side. Then acoustic equipment listens through the floor for escaping water, and a thermal camera shows the warm trail a hot water line leaves in the concrete.
The spot gets marked on the floor before anything is opened. Our leak detection page describes the tools, and slab leak repair explains the repair options.
What are the signs of a hidden leak?
A water bill that jumps without a change in use, a meter that moves with everything off, a warm spot on a tile or wood floor, damp carpet with no spill, cracks that suddenly appear in flooring, or the sound of water running behind a wall at night.
Outside, a patch of lawn that stays green or soggy in a dry week can point to a leak in the line between the meter and the house.
Spot repair or reroute?
A single leak in otherwise sound pipe can be fixed through a small opening in the floor. When a line has leaked before, rerouting it overhead through the attic and walls takes it out from under the slab for good. We give you a written price for each option.
When leaks keep coming in different places, the pipe itself may be done, and our repiping in Temecula page covers that decision.
Where in Temecula do we do this work?
- Paloma del Sol. A warm spot on a kitchen or hall floor is the classic sign of a hot water line leaking under the slab, and we confirm it before cutting anything.
- Vail Ranch. If the bill climbs and the floors are dry, we check the line from the meter to the house and the irrigation tie-in before going inside.
- Margarita Village. In a home plumbed before the mid-1990s, a leak is worth a look at the pipe material, since some houses that age may have polybutylene.
- Temeku Hills. Running water sounds with every fixture off point to a hidden leak, and a pressure test narrows it to a section in minutes.
What do Temecula homeowners ask about leak detection & repair?
How do I check my Temecula home for a hidden leak?
Turn off every fixture and appliance, then watch the water meter. If the dial or the small leak indicator moves, water is escaping between the meter and your taps.
Can you find a slab leak without breaking up my floor?
Yes. We locate it with pressure, acoustic and thermal testing first, so the only opening is at the leak itself, or none at all if the line is rerouted overhead.
Why do slab leaks happen in newer Temecula homes?
Usually wear at a fitting or where pipe rubs against concrete as hot lines expand and contract, with high house pressure adding strain. We check the pressure regulator on every leak call.
Is a small leak worth fixing right away?
Yes. A small leak under a slab keeps wetting the concrete and the soil beneath it, and the water bill rises every day it runs.
Does homeowners insurance cover leak detection?
It depends on the policy. Some cover opening and closing the floor or walls and the water damage, but not the pipe repair. Ask your insurer before work begins.
