Emergency repair for burst and leaking pipes before damage spreads.
Learn moreLeak Detection in Long Beach, CA
A water bill that jumps, a meter that never stops, or a warm spot on the floor usually means water is escaping somewhere you cannot see. California Plumbing Pros finds hidden leaks in Long Beach homes using pressure isolation, acoustic listening, thermal imaging, and tracer gas, before walls, floors, or landscaping are opened.
Non-Invasive Detection
We locate the leak with equipment first, so demolition stays small and targeted.
Slab and Wall Leaks
From under-slab copper to behind-wall supply lines, we find the source.
Meter and Pressure Testing
We confirm water loss and isolate hot from cold before recommending repairs.
Repair Options
Spot repair, reroute, or repipe, explained with the trade-offs of each.
Finding Hidden Leaks in Long Beach Homes
East Long Beach and Los Altos are full of slab-on-grade homes built after World War II. Their copper supply lines run directly under the concrete, and after decades of contact with soil, rebar, and water, pinholes form. Beachfront and coastal properties add salt air that corrodes exposed fittings, hose bibs, and water heater connections. Inland, tree roots and older galvanized lines cause a different set of leaks.
Not every leak is where the stain appears. Water follows the path of least resistance along a slab, inside a wall cavity, or through a planter bed, so the visible damage can be several feet from the failure. We confirm the loss first, isolate hot from cold, and locate the source before recommending a repair.
- Under-slab leaks on hot or cold water lines
- Leaks inside walls, ceilings, and cabinets
- Yard, irrigation, and main service line leaks
- Fixture, hose bib, and water heater connection leaks
Signs of a Hidden Leak in Long Beach
Water waste often shows up on the meter or the bill before it shows up on the floor.
Meter Keeps Moving
With every fixture off, a spinning meter means water is still flowing somewhere.
Water Bill Spike
A sudden increase without a change in usage is one of the most reliable clues.
Warm Spot on the Floor
A hot-water leak under a slab can heat the flooring above it.
Running Water Sound
Hissing or running water with everything off points to a pressurized leak.
Damp Spots or Mold
Musty odors, bubbling paint, or damp carpet can mean a slow leak behind a surface.
Cracks or Low Pressure
Shifting soil and water loss can crack finishes and drop pressure at fixtures.
How Our Long Beach Leak Detection Process Works
Detection comes before demolition. We confirm, isolate, and pinpoint the leak.
1
Confirm the Loss
We check the meter and use pressure testing to verify that a leak exists.
2
Isolate and Locate
We separate hot and cold systems, then use acoustic, thermal, or tracer-gas equipment to pinpoint the source.
3
Mark and Explain
We mark the leak location, document the finding, and explain the repair options.
What Long Beach Leak Detection Includes
Detection is a separate skill from repair. We use the meter, pressure gauges, acoustic microphones, thermal imaging, and tracer gas as needed, then mark the location so the repair can be targeted. You get a clear explanation of what failed and a plan for fixing it. Learn more about professional leak detection or return to the Long Beach plumbing page.

What Affects Leak Detection Cost in Long Beach
Finding the leak is its own job. These factors determine how much time and equipment it takes.
Leak Location
A visible fixture leak is quick; a quiet leak under tile or a slab takes more equipment.
Hot vs Cold Line
Hot-side leaks often show up thermally; cold-side leaks can be quieter and harder to find.
Access and Finishes
Tile, hardwood, cabinets, and landscaping raise the cost of both detection and repair.
Timing and Repair Scope
After-hours detection costs more, and the repair approach changes the total project.

Leak Detection in Long Beach, CA: FAQs
Answers to the questions Long Beach homeowners ask us most.
How do I know if I have a hidden water leak?
Check the meter with every fixture off. If it moves, note the reading, wait an hour, and check again. A rising bill, warm floor, or running-water sound also point to a leak.
Can you find a leak without breaking concrete?
In most cases, yes. We use pressure isolation, acoustic listening, thermal imaging, and tracer gas to locate the leak before any concrete is opened.
Do you repair the leak after finding it?
Yes. We can complete a spot repair, reroute the line, or recommend a repipe depending on the pipe condition and the leak history.
Why is my Long Beach water bill suddenly high?
Leaks, irrigation problems, running toilets, and changes in usage can all raise the bill. A meter test and a fixture check help narrow it down.
Are slab leaks covered by homeowners insurance?
Policies vary. Sudden water damage is often covered, while the pipe repair itself is frequently excluded. Check your policy before filing.
Do you offer emergency leak detection?
Yes. If a leak is active and causing damage, call (800) 390-6351 any time for 24/7 help.
