Leak Detection & Repair
Bay Area's #1 Choice

We use non-invasive technology to pinpoint the exact source of the moisture. Acoustic sensors allow us to "hear" the sound of water escaping under high pressure, while thermal imaging cameras detect temperature differences behind drywall or under floors. This accuracy means we only cut into your home where it is absolutely necessary for the repair.

If you notice unexplained warm spots on your floor, a sudden drop in water pressure, or the sound of rushing water when all faucets are closed, you likely have a slab leak. Left unaddressed, these leaks can wash away the soil beneath your home, leading to foundation cracks and significant structural shifting.

Most high-water-bill culprits are invisible. A leaking toilet flapper can waste over 200 gallons a day without making a sound. Similarly, a pinhole leak in a crawlspace or a service line underground won't show up in your living area. We perform a systemic pressure test to determine if the leak is in your appliances or your main supply lines.

The "Meter Test" is the most effective DIY method. Ensure all water in the house is turned off. Check your water meter’s low-flow indicator (often a small red or blue triangle). If it is spinning, water is moving somewhere in the system. If you shut off your main valve and it still spins, the leak is in the underground line between the meter and your house.

Yes. A tiny drip can release gallons of water over a 24-hour period. Constant moisture behind a wall leads to mold growth in as little as 48 hours, which compromises air quality. Long-term leaks can also cause wood rot in your floor joists and studs, requiring expensive structural restoration.

No, water and gas leak detection require different specialized equipment. For gas, we use combustible gas indicators (sniffers) to detect ppm levels of methane. If you smell gas (a "rotten egg" odor), you should evacuate immediately and call emergency services before we perform a pressure test to locate the breach.

If the leak was caused by physical damage (like a nail through a pipe), a localized patch is sufficient. However, if the leak is due to corrosion or "pitting," it’s a sign that the entire pipe is thin. In those cases, we recommend replacing the full run to prevent a "cascade" effect where new leaks appear shortly after the first one is fixed.

Most leak detection appointments take 1 to 3 hours. Once the source is found, many minor repairs can be completed on the same day. For more complex issues, like those under a concrete slab, we provide a detailed repair plan and timeline to restore your system as quickly as possible.

Yes. We use pressurized air and acoustic equipment to isolate leaks in underground sprinkler manifolds or pool supply lines. These leaks are often the cause of unexplained sinkholes in the yard or "mushy" patches of grass even when it hasn't rained.

Yes. A major burst requires immediate intervention to stop the flow and minimize property damage. We provide 24/7 emergency response to shut off the water, diagnose the failure, and perform immediate repairs, helping you get the water back on and the drying process started right away.
