Water leak detection in Ventura
Leak detection is the process of finding a hidden water leak's exact location without tearing open walls or floors to search for it. We use acoustic listening, thermal imaging and pressure testing to pinpoint leaks in Ventura homes, then we repair them.

- A water bill higher than usual with no change in how you use water.
- The water meter dial moves when every tap and appliance is off.
- The sound of running water inside a wall or under the floor.
- Warm spots on a tile or concrete floor, a sign of a hot water slab leak.
- Stains, bubbling paint or soft drywall on walls and ceilings.
- Musty smells or mold behind cabinets and baseboards.
- A patch of lawn that stays green or soggy in dry weather.
How to check your meter for a leak
- Turn off every tap and water-using appliance, including irrigation.
- Open the meter box near the curb and note the reading, or watch the small leak indicator (often a triangle or star).
- Wait 30 minutes without using water.
- Check again. If the reading changed or the indicator turned, water is leaking somewhere after the meter.
Ventura Water customers with the new smart meters can also see hourly use and leak alerts through the city's Web Connect tool, according to Ventura Water.
How we find leaks
| Method | What it does | Used for |
|---|---|---|
| Pressure testing | Isolates hot, cold and irrigation lines to see which one loses pressure | Confirming a leak and which system it's on |
| Acoustic listening | Ground microphones pick up the sound of water escaping a pipe | Slab leaks, buried yard lines |
| Thermal imaging | Shows temperature differences through surfaces | Hot water leaks in slabs, walls and ceilings |
| Moisture meters | Measure water content in drywall, wood and flooring | Mapping how far water has spread |
| Video inspection | Camera inside drain and sewer lines | Drain leaks and broken laterals |
Leak repair after we find it
Once we find the leak, the repair depends on the pipe and where it runs.
- Accessible pipe in a wall or ceiling: a small opening and a spot repair.
- Under a concrete slab: a spot repair through the floor, or a reroute through walls or the attic. See slab leak repair.
- Yard and main water lines: a section replaced from the meter to the house. See water main line repair.
- Repeated pinhole leaks in copper: usually a sign the system is due for whole-house repiping.
Why leaks are common in Ventura homes
Ventura's housing stock is aging: the median home was built in 1973, according to Census data. Many of those homes have copper supply lines under a concrete slab foundation. Decades of very hard water inside and soil movement outside wear those pipes down.
How pricing works
Every job is different, so the cost depends on the type of work and what the job requires. We look at the problem first, explain your options, and confirm the price with you before any work starts.
Ventura Water has a leak adjustment policy that may reduce a bill after a repaired leak. Keep your plumber's invoice; call Ventura Water at (805) 667-6500 to ask if you qualify.

Leak detection questions
Will you have to break my walls or floor?
Usually only at the leak itself. Pinpointing the location first means one small, targeted opening instead of exploratory demolition.
Does homeowners insurance pay for leak detection?
It depends on the policy. Many policies cover the cost of accessing and repairing sudden water damage. We provide a written report with photos for your claim.
Can a leak be on Ventura Water's side?
Yes. If the leak is at the meter or in the street, it belongs to Ventura Water. Call their after-hours emergency line at (805) 650-8010.
