Where hidden leaks hide in Laguna Niguel homes
Inside walls and ceilings. Supply lines to bathrooms, kitchens and laundry rooms run behind drywall. A pinhole there can stay hidden for weeks before a stain, bubbling paint or a musty smell shows up. In two-story homes, a leak upstairs often first appears as a ceiling stain below.
Under the slab. Much of Laguna Niguel was built in the 1970s–90s, and many of those homes still run original copper lines through or under the concrete. A warm spot on the floor or the sound of running water with everything off are typical signs. Details on our Laguna Niguel slab leak page.
Between the meter and the house. The buried service line, and irrigation lines on hillside lots, can leak for a long time with no sign indoors except the bill. A soggy patch of lawn or a spot that stays green in a dry month can point to it.
Check for a leak yourself first
Turn off every faucet, appliance and irrigation zone, note the reading on your water meter, and check again after 30 minutes. If it moved, water is leaving the system somewhere. Our water meter test guide walks through it. Laguna Niguel is served by Moulton Niguel Water District, so your bill history there is a good place to spot an unexplained rise in use (see why is my water bill so high?).
- Pressure testing to isolate the hot line, cold line or service line
- Acoustic leak location through drywall, tile, wood or concrete
- Electronic pipe locating to trace lines in walls, under the slab and in the yard
- Thermal imaging to confirm hot-water leaks
- Repair once the leak is found, or a slab leak reroute or PEX repipe when that is the better call
- Written findings to bring to your insurer (no coverage promises)

Find the leak first, then a straight answer on the fix
Which line is leaking?
Pressure testing shows whether the hot line, cold line or the service line from the meter is losing water, so we know where to look.
Listen, trace and confirm
Acoustic equipment picks up the sound of pressurized water escaping, electronic locating traces where the pipe runs, and thermal imaging cross-checks hot-water leaks. The spot is marked for the smallest possible opening.
Repair, reroute, or repipe
A single leak in a sound line is usually a spot repair. Repeat leaks in aging copper may make a reroute or repipe the smarter call. We explain the trade-offs after diagnosis, never before.
Common questions from Laguna Niguel homeowners
Straight Flush Plumbing & Leak Detection locates hidden water leaks in Laguna Niguel homes: inside walls and ceilings, under the slab, and in the buried line between the water meter and the house. We're an owner-operated plumbing company based in Laguna Niguel, we use acoustic, electronic and thermal detection to pinpoint the leak before anything is opened, and owner Lance answers the phone at (949) 374-6524.
For most homes, leak detection runs $365 to $525. Where you fall depends on the size of the home, how many areas need testing, and whether the leak is under the slab, inside a wall or underground. You get a clear number before the visit is scheduled.
Common signs are a water bill that rises for no reason, a water meter that keeps moving with every fixture off, the sound of running water when nothing is on, a warm spot on the floor, damp or stained drywall, a musty smell, or a soggy patch in the yard. The simplest check is the water meter test: turn off every fixture and irrigation, note the meter, and look again after 30 minutes.
In most cases, yes. Pressure testing tells us which line is losing water, acoustic equipment listens for the leak through drywall, tile or concrete, electronic locating traces where the pipe runs, and thermal imaging helps confirm hot-water leaks. The goal is one small, targeted opening at the leak, not exploratory demolition.
If you're filing an insurance claim, insurance typically reimburses the leak detection cost. Coverage depends on your policy and the cause of the leak, so check with your insurer. We give you written findings, including the affected line, its location and what we found, to bring to them.
A pressure test answers that. If the house lines hold pressure but the meter still moves, the leak is usually on the service line between the meter and the house, or on an irrigation line. If a house line drops pressure, the leak is inside the home, and we narrow it down from there.
