Water Leak Locating, Detection and Repair
Are you spending money on a water leak?
Is it threatening your landscape or your home’s foundation?
Our Leak Locating service is $375 in most cases, which is upwards of 40% less than the leading competitor.

With most water lines hidden underground or behind walls, signs of a leak, like increased water bills, damp areas, or water pressure issues, are often noticed before the actual leak location. Finding a hidden leak requires specialized equipment and expertise in using that equipment. Our Water Leak Locating Service provides a non-invasive method to pinpoint the problem so it can be repaired efficiently.
If you know the spot of your leak, call us today at 📞408-693-6018 or use our contact form to schedule a free repair estimate. If you need help finding your leak, a necessary step before a repair can be done, contact us to schedule a non-invasive Leak Locating Service. The cost is $375 for Leak Locating/Detection for most properties (longer water line runs which require most tracer gas or situations that require more than hour may be more–we will let you know when booking). We do not think you will not find a better price for this service—but if you do, let us know so we can match it for you. Once the location of the water leak is know, a repair estimate can be made and if the repair is substantial, we can credit the cost of the detection service toward the repair. We look forward to helping you with your water leak.Â
Our Water Leak Locating/Detection Service
Advanced, Non-Invasive, and Precise Water Leak Detection, Locating, and Repair Service in the Greater San Jose Area, parts of San Mateo, Santa Cruz and Alameda Counties
Water leaks drive up your monthly utility bills and, at worst, can damage your landscape and your home’s foundation. The source of a water leak is not always easy to find without specialized equipment. We can locate leaks behind walls, underground, and even beneath pavers or concrete. Freedom Underground offers top-end, non-invasive leak detection using acoustic and tracer gas equipment if you suspect a water leak but cannot find it. Any plumber can dig up and repair a leak, but no one can fix a leak they cannot find. Save your time and avoid disrupting your landscape by zeroing in on the exact location before digging.
With our service, we locate the leak, mark the spot, and provide a detailed spot repair estimate so you can make an informed decision. With our Lifetime Warranty for repairs, replacements, or new installations, you can trust that our repairs will be backed for life. If your leak requires more than a spot repair, we can credit the leak detection cost as a discount on the larger repair job.
Our tools and methods are highly sensitive, and most importantly, highly accurate.
By zeroing in the specific area of a leak, we save our customers time, money, and disruption to the landscape by only digging in the area where we detected the leak.Â
We typically use a tracer gas leak detector system which provides accurate results in finding leaks underground. We isolate a section of pipe, inject it with a non-toxic, non-flammable, and safe tracer gas mixture of 5% hydrogen and 95% nitrogen. If there is a leak, the tracer gas will escape at the leak point, then rise to the surface where we can detect it. This system works even through concrete slabs, walls, floors, and over 10 feet underground.
If the environment is not too noisy, we can, alternatively, use an acoustic detector. Even a small leak will make some noise, which can be detected with the right equipment. The other time we may want to use the acoustic detector is if the water line is PVC and lacks a tracer line, a common construction in the 1980s. If your line is PVC and without a tracer wire, we cannot use a surface detector to locate where the path of the pipe runs. In this case, an acoustic tracer system will allow us to find the line location.



If you suspect you may have a water leak but cannot easily find it, we can. We will find the leak and offer a free estimate for a quick repair. Costs for our Leak Detection Service is $375 for most cases. Call us at 📞408-693-6018 or use our contact form to schedule and result your water leak problem.
Below is a video example of the moment we found a leak for a customer in Santa Clara. To pinpoint the spot of the leak, we used our Sewerin VARIOTEC 460 system which you see in the below video. The leak was on an irrigation line and we detected the leak at a 90 elbow, right before an irrigation valve. The line branched off from there and continued across a driveway to irrigate a planting area. We also detected a small leak at one of the irrigation valves located on the far side of the driveway. The valve would not fully close and needed replacing.
The water leak fix, in this instance, was to dig in the lawn to replace a 90 elbow, and also replace the faulty irrigation valve. Both were relatively easy fixes and we recommended the homeowner ask their gardener to make the repairs as the least costly solution.
