A water bill that jumped for no reason, a warm patch on the floor, the sound of running water with every tap closed. We pinpoint hidden leaks across Pacifica, San Francisco, and Burlingame using acoustic listening, thermal imaging, and pressure isolation, so the wall or slab only gets opened where the leak actually is.

The expensive part of a hidden leak is rarely the repair. It is the exploratory demolition that comes from guessing. We have been called to homes where three holes had already been cut in the drywall before anyone thought to isolate the line, and the leak turned out to be in a different room entirely.
So we locate first. Pressure isolation tells us whether the loss is on the hot side, the cold side, or the irrigation, which immediately halves or quarters the search area. Acoustic equipment picks up the specific frequency of pressurised water escaping a pipe, even under a slab. Thermal imaging finds the temperature signature of a hot water line leak behind plaster without touching it. On older galvanised systems around the coast we also look for the pattern of failure rather than the single hole, because where one pinhole has gone others usually follow.
You get a clear answer on where the leak is and what the repair involves before anything is opened up. Book a free estimate any time, no obligation.
Thank you again for another job well done, and thank you for responding right away. I will continue to recommend Works Plumbing because they respond right away and get the job done efficiently.

Every leak detection visit comes with upfront pricing, licensed and background-checked technicians, and a 100% satisfaction guarantee. Works Plumbing holds California contractor license #982663, carries full bonding and insurance, and holds an A+ rating with the Better Business Bureau.
We are a plumbing-only shop, which means the tech at your door has spent years on this exact work rather than splitting time across three trades. Our crews are drug tested as well as background checked, and dispatch is staffed by real people around the clock. No surprises, no commission-driven upsells, no pressure, ever.
You can confirm a leak yourself in ten minutes. Turn off every fixture in the house, then look at the water meter and note the position of the small sweep hand or the leak indicator triangle. Wait fifteen minutes without using any water and look again. If it has moved at all, water is going somewhere it should not be. That one test tells us the search is worth starting.

Here are the questions we hear most. Don’t see yours? Give us a ring, a real human answers, day or night.
No. The whole point of the equipment is to locate the leak without opening anything. Acoustic listening, thermal imaging, and pressure isolation all work from the surface. The only thing that gets opened is the specific spot where the repair happens, once we have confirmed the location. If a company wants to start cutting drywall to hunt for a leak, get a second opinion.
The usual signs are a warm or damp patch on the floor, a persistent sound of running water with everything turned off, an unexplained jump in the water bill, or a hot water system that struggles to keep up. Cracking in flooring or a musty smell with no visible source is another. Any one of those is worth a meter test, and if the meter is moving with all fixtures closed, it is worth locating properly.
More than people expect. A pinhole leak losing a steady drip runs into thousands of gallons a year, and a slab leak under pressure can waste that in weeks. Beyond the bill, the damage compounds quietly: saturated subfloor, compromised framing, and mould in wall cavities all cost far more to put right than the leak repair. Finding it early is almost always the cheaper decision.
That depends on your policy, and we are plumbers rather than insurers, so we will not tell you what your cover includes. What we can do is give you documentation that helps: the location, what failed, photographs, and a written scope of the repair. Many policies treat sudden pipe failure differently from long-term seepage, so having a dated record of what we found and when tends to matter.
Yes. Works Plumbing holds California contractor license #982663, carries full bonding and liability insurance, and is accredited with an A+ rating from the Better Business Bureau. Every technician who comes to your door is background checked and drug tested, and arrives in a marked Works van in uniform. If you want to verify the license before booking, you can look it up on the California Contractors State License Board website.
Usually yes. We run stocked trucks out of all three of our locations in Pacifica, San Francisco, and Burlingame, so there is generally a van already working near you rather than one dispatched from across the county. Our average on-site response for emergencies is under 60 minutes, and dispatch is staffed 24/7 including weekends and holidays. A real person answers the phone, so you will know within minutes whether we can be there today.
Three Peninsula locations put a stocked truck near you, from San Francisco down to Atherton, covering 22+ cities every day.
