A San Diego Leak Detection Plumber Who Protects Your Home
A hidden water leak is one of the most expensive problems a home can face. It can run for months behind a wall or beneath a slab, quietly driving up your water bill while it softens drywall, rots framing, and feeds mold.
San Diego's water is part of the problem. Our supply carries roughly 16 to 18 grains per gallon of dissolved minerals, which pits copper. Add high water pressure, aging galvanized and cast-iron lines, shifting soil under slab-on-grade homes, and tree roots, and leaks become common. A&A Plumbing has repaired hidden leaks across San Diego County since 2020.
Shut off all water, note your meter reading, wait 30 to 60 minutes, and check it again. If the meter moved, you have a leak. Call (619) 637-5215 and we will pinpoint it.

Leak Detection
Acoustic listening, thermal imaging, and line tracing pinpoint the source fast.
Detection →Slab Leak Detection
Warm floors and rising bills often mean a slab leak. We locate it before opening concrete.
Slab leaks →Pinhole Leak Repair
Hard water pits copper and creates pinhole leaks. We repair or replace the pipe.
Pipe costs →Under-Sink & Supply Line Leaks
Dripping traps, loose fittings, and worn supply lines, fixed fast.
Bathroom →Water Heater Leak Repair
Leaking at a fitting, valve, or tank? We diagnose it and lay out your options.
Water heaters →Repiping for Chronic Leaks
When a home springs leak after leak, repiping with copper or PEX stops the cycle for good.
Repiping →Signs You May Have a Hidden Water Leak
Leaks rarely announce themselves. The first clue is usually a higher water bill or a small mark on a wall.
- An unexplained spike in your water bill
- A meter that still spins with every fixture off
- Damp, warm, or discolored spots on the floor
- A musty smell, mildew, or bubbling paint

Water Leak Questions, Answered
Still have a question? Call (619) 637-5215.
How much does leak detection cost in San Diego?
Leak detection in San Diego typically runs $150 to $500. Slab leak detection is usually $300 to $600, and a pinhole or supply line repair costs $250 to $900.
How do you find a leak without breaking into walls?
We start non-invasively: acoustic listening discs, thermal imaging, pressure and temperature testing, tracer gas, and electronic line tracing. That pinpoints the leak before we open walls or break concrete.
What causes water leaks in San Diego homes?
Hard water at 16 to 18 grains per gallon pits copper, and high pressure stresses joints. Aging galvanized and cast-iron pipes, shifting soil, tree roots, and worn valves also cause leaks.
What are the warning signs of a hidden water leak?
An unexplained high water bill, a meter that still spins with all fixtures off, damp or warm floor spots, a musty smell, bubbling paint, or foundation cracks.
