Leak Detection in San Diego

Professional leak detection uses acoustic listening devices, thermal imaging, moisture meters and pressure testing to pinpoint a hidden leak without tearing open walls or floors. The fastest at-home check: turn off every fixture and watch your water meter — if it still moves, you likely have a leak.

The water meter test

1. Turn off all faucets, appliances, irrigation and the ice maker.
2. Find your water meter (usually in a box near the curb) and note the reading or the small leak indicator.
3. Wait 30–60 minutes without using water and check again. Movement means water is going somewhere.

Where hidden leaks hide

• Under the slab — see slab leaks.
• Inside walls behind showers, sinks and toilets.
• Irrigation and pool lines in the yard.
• Water heater and appliance connections.

Why find it early

A small hidden leak can quietly soak framing and subfloor for weeks. The EPA's guidance is to dry water-damaged materials within 24–48 hours to help prevent mold growth (EPA).

How the tools work

• Acoustic listening: sensitive microphones pick up the sound of water escaping a pressurized pipe, even under concrete.
• Thermal imaging: hot-water leaks and evaporating moisture show up as temperature differences on walls and floors.
• Moisture meters: confirm whether materials are wet and how far it spread.
• Pressure testing: isolates sections of plumbing to show which line is losing pressure.

What happens after the leak is found

Once the spot is marked, a plumber repairs the pipe and a restoration pro dries any wet areas. Ask the leak detection company for a written report with photos; it helps with both the repair and any insurance claim.
