Acoustic Leak Detection
Electronic listening equipment picks up the sound of pressurised water escaping a pipe, so the leak can be pinpointed through floors and walls.
Services Directory
Our Leak Detection Services
Fifteen specialist services for Alhambra and the San Gabriel Valley — four diagnostic methods, location services for slabs, walls and underground lines, pool and sewer inspection, commercial surveys, moisture documentation, and evidence-based repair options.
Detection Methods
Thermal Imaging Leak Detection
Infrared cameras reveal temperature patterns on walls, floors and ceilings that can point to hidden moisture and hot-water leaks.
Tracer Gas Leak Detection
A safe tracer gas introduced into a drained line escapes at the leak point and is detected at the surface — ideal for tiny or silent leaks.
Video Camera Pipe Inspection
A push-camera travels inside accessible drain and sewer lines, showing roots, cracks, offsets and blockages on screen in real time.
Pipeline Pressure Testing
Isolating a line and monitoring its pressure confirms whether it leaks, and which section — hot or cold, inside or outside — is responsible.
Leak Location Services
Slab Leak Detection
Locating leaks in supply lines under a concrete slab — using meter confirmation, line isolation and acoustic, thermal or tracer-gas pinpointing.
Wall and Ceiling Leak Detection
Tracing stains, bubbling paint and damp plaster back to their true source — which is often not directly behind the visible damage.
Underground Main Line Leak Detection
Pinpointing leaks in the buried service line between the water meter and your home — without digging up the yard to search.
Emergency Water Shut-Off & Isolation
Calm, practical help for active leaks: stopping the water safely, isolating the affected line, and locating the failure.
Pool, Sewer & Pipe Inspection
Pool and Spa Leak Detection
Separating normal evaporation from real water loss, then testing shell, fittings, equipment and plumbing to find where pool water is going.
Sewer and Drain Line Tracking
Camera inspection plus surface locating: know exactly where your sewer line runs, how deep it is, and where each defect sits.
Commercial Investigations
Commercial Water Loss Surveys
A systematic investigation of unexplained water loss in commercial buildings, HOAs and multi-unit properties — zone by zone, documented.
Structural Moisture Mapping
Measuring and documenting exactly where building materials are wet, how wet they are, and how far the moisture has spread.
Pipe Repair & Rehabilitation
Trenchless Pipe Relining
Renewing a damaged drain or sewer line from the inside with a cured-in-place liner — when the pipe is a suitable candidate.
Targeted Spot Pipe Repair
Repairing one identified defect — a cracked joint, a root entry point, a single damaged section — instead of replacing the whole line.
How to choose the right service
Not sure if you have a leak?
Start with symptoms. A meter test confirms a loss; pressure testing then shows which section is responsible.
Know the system, not the spot?
Go by location: slab, wall & ceiling, underground main line, pool & spa.
Drain or sewer problem?
Start with a camera inspection. Its evidence decides between monitoring, a spot repair and relining.
Diagnosis vs repair — an important distinction
Most services on this page are diagnostic: they prove and locate a problem. Two — trenchless relining and targeted spot repair — are repairs, and both are only offered after camera evidence shows the pipe qualifies. That order (evidence first, repair second) is deliberate, and it is how unnecessary work is avoided.
Services FAQs
I don't know which service I need — what should I do?
Call and describe the symptoms. The visit normally starts with confirmation and isolation, and the specific method is chosen from the evidence — you do not need to pick the right page first.
Are all 15 services available in every area?
Core detection services are offered across our Alhambra and San Gabriel Valley service area. Repair services depend on the individual pipe's condition and are confirmed after inspection.
Do detection services include repair?
No — detection and repair are separate steps with separate scopes, so you can act on the findings with any provider. Repair options are explained once the evidence is in.

Think you have a hidden leak?
The sooner a leak is confirmed and located, the less water is wasted and the less damage spreads. Call now, or send a short request and describe what you are seeing.
