Emergency Leak Detection in Laguna Hills, CA
A hidden leak wastes water and soaks building materials long before you see a stain. Call the 24/7 line, and we find the source with meter checks and listening equipment, then explain the repair and the price.
- 24/7 emergency line.
- Clear price before work starts.
- Licensed and insured.
When a leak is an emergency
Water coming through a ceiling, pooling on a floor or running when every fixture is off is an emergency, and our line is open 24/7. While you wait, shut off the main water valve and keep people away from wet electrical areas.
Same-day visits are offered when a crew is free, and after-hours calls are taken the same way as daytime ones.
- Turn the main water valve clockwise to close it. It is usually at the front of the house, near the meter, or in the garage.
- Stay out of rooms where water is near outlets, and switch off the breaker only if you can reach the panel without standing in water.
- Move furniture and electronics out of the wet area and lift rugs so they can dry.
- Take photos of the damage for your records and tell us where the water appears.
Check the meter before you call
You can test for a leak in two minutes. Turn off every fixture and appliance that uses water, then look at your meter. If the small leak indicator is spinning or the dial moves, water is going somewhere.
That test tells you a leak exists, not where. Locating it takes tools, and that is the work we do.
How we find a hidden leak
We combine several methods because no single tool finds every leak. A pressure test on the supply lines shows whether a leak is on the hot side, the cold side or both. Acoustic listening equipment picks up the sound of water escaping from a pressurized pipe.
- Meter and pressure tests to confirm the leak and narrow it to a line.
- Acoustic ground and wall microphones to hear water leaving the pipe.
- Thermal imaging to show warm hot water lines behind a surface.
- Moisture meters to map the wet area before any wall is opened.
- A camera inspection when a drain line is the suspect.
Once the source is located, we mark it and explain the repair. Opening a small access point costs less to restore than opening a whole wall.

Call (949) 325-3122High water bills and your water district
Laguna Hills is served by more than one water district. The El Toro Water District serves portions of the city, and Moulton Niguel Water District serves other parts. Your bill shows which one applies.
If your bill jumps, ask your district for a usage history. The El Toro Water District can be reached at (949) 837-0660, and Moulton Niguel Water District at (949) 831-2500. A steady rise with no change in habits suggests a leak.
Leaks under the house, in walls and in the yard
A leak under a raised floor shows up as a damp crawlspace, a musty smell or a floor that feels soft. A leak behind a wall or above a ceiling shows up as a stain that grows, paint that bubbles or a patch that stays warm. Both are hidden, so we locate the pipe first and open only what we must.
Outside, a buried supply line can leak for months. Look for a soggy patch of lawn with no rain, a wet meter box or a meter that moves while the house is off. Irrigation lines and pool plumbing leak the same way, and we test them separately so we can tell whose pipe is failing.
Low water pressure is a clue too. A steady drop with no change at the street can point to a leak or a corroded line, while a drop at a single fixture usually points to a clogged aerator or a worn valve.
Fixes and what they involve
Some leaks need a simple valve or fitting change. Others need a wall opened or a pipe rerouted. We explain the repair and the price before work starts, and we protect the area as we work.
Plumbing repairs follow the California Plumbing Code, which is based on the Uniform Plumbing Code (UPC). Ask the Building & Safety Division at (949) 707-2600 when a repair involves replacing a long run of pipe.
Leak Detection questions, answered
Do you handle leak emergencies at night or on weekends in Laguna Hills?
Yes. The line is open 24/7. Shut off the main water valve first, then call, and we book a visit as soon as a crew is available.
How do I know if I have a hidden leak?
Turn everything off and check the meter. A moving dial or spinning indicator means water is leaking somewhere. A warm patch on the floor or the sound of running water are other signs.
Will you cut into my walls?
Only when needed. We locate the leak with listening gear and moisture mapping first, so any opening is small and in the right place.
Can you find a leak in the yard?
Yes. Water service line leaks often show as wet soil near the meter or along the path to the house. We trace the line with listening equipment.
Do you charge to find the leak if you cannot fix it?
We explain the price for locating the leak before we start, and we tell you what is included.
