Leak Detection & Emergency Plumbing

A hidden slab or main-line leak can waste thousands of gallons before you see a drop of water. We use electronic leak detection to find it fast — and we answer emergency calls 24/7.

Leak Detection & Emergency Plumbing: What's Included

Not every leak shows itself. Slab leaks, main-line leaks and leaks inside walls often hide until the water bill spikes or a floor starts feeling warm in one spot. We use acoustic and electronic leak detection equipment to pinpoint the exact location before we dig or cut into anything — the same precision that goes into a main-line repair like the one pictured here.

When it's an active emergency — a burst pipe, a flooding water heater, a main line spraying in the yard — our on-call crew answers the phone 24 hours a day and dispatches a truck immediately.

FAQ

Common Questions

For active emergencies like burst pipes or major leaks, we prioritize dispatch and aim to have a plumber on-site as quickly as possible, day or night.
Electronic acoustic detection listens for the sound signature of escaping water and pinpoints the leak location before any cutting begins.
If it's safe to do so, shut off your main water valve to limit damage, and move valuables away from the affected area.
We provide detailed photos, camera footage and repair documentation you can submit with your claim.
