Save yourself the trouble and call South Bay Leak Detection and Kerry first. I cannot recommend him highly enough for his comprehensive and methodical approach to leak detection. I have a 40-year-old pool with a very tricky leak in a return line that did not immediately show up with typical line pressurization settings. While a less experienced technician might have missed it, Kerry showed great perseverance. He stayed with the problem, meticulously adjusting his diagnostics until he was certain he had pinpointed the exact failure point. The accuracy of his work was absolutely spot on, as verified by the subsequent repair work--the leak was exactly where he said it would be. To top it off, he referred me to a repair company that did an excellent job, showing he's well-connected with other top-tier pros. Kerry is a true specialist who takes pride in precision. If you want a definitive and correct answer the first time, for a fair price, call South Bay Leak Detection. read more

South Bay Leak Detection - Bullseye! The leak turned out to be right there exactly. - Plumbing Near Me

I contacted South Bay Leak Detection for diagnosing a yellow stain on my downstair closet ceiling. Kerry came and did the water test as well as a thermal test in my two up stair bathrooms. He also saturated the slanted roof above my coat closet but no sign of leak was noticed. He suggested that I could wait for the rainy season to determine if the concern becomes active only during a storm and recommended that I consult with a roof expert for possible resolutions. Even though he could not recreate the leak at this time but he did take his time to do a thorough test. He also noticed there are water dripping from my garden watering faucet when it was turned on and he fixed it for me. read more

Kudo to Kerry, I had a good experience with Kerry's service for the following reasons: 1) He sent a detailed contract beforehand, and patiently answer all my questions and the response is crystal clear. 2) He is on-time, he arrives right on the time he responded. 3) He is professional, he quickly found out the leak point, it is actually from my irrigation system. 4) Extra mile, even in the contract only single leak point is promised, Kerry is still helping to try to locate the tiny leak inside or outside the house, in the end he told me his conclusion explain everything in detail. 5) Kerry also brings his own shoe cover and ask my permission for any bathroom check before doing the inspection. Finally, the price, I think he provides reasonable price in bay area nowadays. read more

Highly recommend Kerry! We had plumbers, contractors, handymen, and even a builder try to help us investigate a leak -- but Kerry was the one who actually found the source. It turned out to be our refrigerator filter. We never would have found it without his equipment and expertise. Dealing with a leak is always frustrating, but Kerry made the process so much easier. He's professional, organized, and communicates clearly. Definitely worth every penny -- the peace of mind alone made it worth hiring him. Truly appreciate his work! read more

Good value for the service - thorough, found the leak, and recommended a plumber for the fix when asked.

I chose Kerry because of his 5-star Google reviews and he did not disappoint. For years we have failed to find the leak in our landscaping. Kerry showed up on time, gave us a quote, found the issue in less than 2 hours, and recommended the fix. A few of the other firms we contacted never showed or pushed us off. I would 100% refer him and if I ever need his services to find any leak, I will use him. read more

Kerry was great to work with and helped us quickly find a tricky leak! He got on the phone and answered all of our questions and quickly scheduled us in.

We had been struggling to find this leak and we are so appreciative that we found South Bay Leak Detection! read more

I received a notification from the city that my house was leaking more than 5 gallons per hour. Unable to locate the leak on my own, I turned to a professional, and Kerry exceeded my expectations. From scheduling the appointment and answering all my questions to the methodical approach to leak detection, recommending a repair professional when needed, and providing a detailed final report, Kerry made the entire process easy and stress-free. It was an excellent experience from start to finish. read more

I can't speak more highly of Kerry and South Bay Leak Detection! I'd resolved all of the obvious irrigation leaks but unfortunately the water meter indicated a deeper issue somewhere and I chose to call Kerry based on his stellar reviews. With a meticulous approach and high attention to detail, he was able to pinpoint several hidden leaks - everything is well documented in his final report (including photos) and remediation is in process - I'm looking forward to a boring water bill soon! read more

Vinyl-lined pool started losing water. When this has happened before, I found the leaks and fixed 'em. I couldn't find this one. It took Kerry 2 visits and a lot of time but he found it, showed me, took videos, etc. So excited that he found it! I've had a few leaks in 20 years and I'm sure it'll happen again. Next time I'm not gonna even try to find it myself... I'm calling Kerry. read more

Kerry at South Bay Leak Detection did a great job finding our leak! We got a notification from the city that we were leaking 7 gallons per hour. I looked in all of the obvious places and had a plumber come out to take a look but we couldn't find the leak. Kerry came out and didn't waste time repeating the work we had already done. He was able to find the leak in just under 2 hours! read more

Prompt. Quick. Effective Found the leak easy. Showed up quickly. Would hire again but hope I don't have to.

Another excellent experience with South Bay Leak Detection. I moved homes, and the new home developed a leak I couldn't find. They did a great job for me last year and this time around was the same. Thanks again! read more

Kerry did a great job locating a leak in the underground return line on our pool. The leak was a tricky one to find, as our pool is 50 years old. He was very methodical and did a thorough job tracking down the leak, as well as making sure there were no other leaks in other suspect areas. Five star service all the way...thanks Kerry! read more

Kerry came to our home to identify water leaks that were small and not apparent to us until our new San Jose Smart Meter was installed a few weeks ago. The meter was constantly showing water consumption even when we were out of town. At first we thought it was an error with the meter. San Jose Water sent a technician out to check for functionality of the meter and it was working correctly. Thanks goodness we enlisted Kerry! He's definitely a pro at leak detection. He was polite, kind, on time, patient, and thorough. He answered all our questions and most importantly solved the mystery of where we had two very small leaks. We highly recommend his services if you should require leak detection. Thank you Kerry! read more

Kerry was prompt, fast, and efficient. He did a quick repair of one leak and confirmed the rest of the system was fine

Great experience. I called South Bay Leak Detection (SBLD) because my water bill suddenly increased 20 times higher than normal and San Jose Water Co. technician inspected the meter and confirmed the meter was working fine. I had a massive water leak somewhere but couldn't hear water running anywhere. That happened less than one week before Christmas and I panicked because some of my family members were staying with me over Christmas. Kerry, the owner/operator of came over within 24 hours on the Saturday before Christmas and worked all morning to find the leak, which he located under my concrete slab floor. He was professional and he knows what he was doing and had the proper equipment do to the job. Very happy with his service. read more

I've been dealing with an intermittent leak whose source couldn't be found by two plumbers. I was hesitant to move forward with the plumbers' recommendations of pulling out cabinets/drywall to locate the leak, so I sought a specialist who might be able to find it in a less invasive manner. I called South Bay Leak Detection and was connected with Kerry, who patiently explained his process and answered all my questions. I understood that this was solely a detection service and would not include a repair. Kerry came out to the house and was able to find the source of the leak quickly, which he subsequently explained to me both over the phone and via a thorough report which included thermal imaging of the problem areas. Leaks are serious bummers in my experience. Drywall gets ruined, you pull out the drywall, you address one area which you think is causing the leak, you repair the drywall, and then whoops - you didn't fix the right leak so now the new drywall is ruined too. As a result, I appreciate the smooth and professional service provided by South Bay Leak Detection to give me hope that the situation can be resolved quickly. read more

I can't say enough good things about South Bay Leak Detection. I noticed my pool water level dropping faster than it should in cold weather, and gave them a call to schedule an appointment. Kerry was very professional. He arrived on time and explained in detail the process for finding the leak. Kerry did an extremely thorough inspection, and found the source of the leak in a very unlikely place (an abandoned port in the hot tub). Communication during and after the inspection was excellent. I highly recommend South Bay Leak Detection. read more

Kerry was great. Super prompt with communication, friendly, professional, and efficient. Got the job done well and quickly. Highly recommend! read more

A pool service company we are working with recommended Kerry when I asked advice about leak detection. Kerry was very responsive to my inquiry, explained what would be done and set expectations. His communication was excellent throughout and he was punctual. He did a thorough investigation of our pool plumbing which turned out to be sound. He did however find a crack between our pool and spa that was responsible for our leak, and was able to seal that for us. I can highly recommend Kerry if you have a leaking pool, from every perspective of our interactions. read more

Called Kerry this week when I woke up to find my inground pool developed a crack and was leaking fast. He got in touch quickly and came by the same day to investigate and test the plumbing to make sure that wasn't leaking. Quickly send a report with pictures and today he returned to patch the crack with some epoxy. Not a permanent fix but will hopefully buy us some time to continue enjoying the pool until the winter! Highly recommended!!! read more

I had a leak on my irrigation with no idea where to start. Kerry was recommended to me by a neighbor and i couldn't be more grateful. He is very knowledgeable and was able to walk me through the process and found the leak in a timely manner. Great service, kind, and respectful. Highly recommend his services. Thank you for the help! read more

Kerry was very easy to work with, on time, and professional. He came to inspect our pool which had been inspected just 6 months ago but had resumed leaking. Kerry was extremely thorough, pressure testing the plumbing first and then even diving into the pool in order to check for hairline cracks deep below the surface. In the end, he identified two small areas near the original leak which still required patching, but also pointed out several other small cracks which we should keep an eye on. All in all, I found him great to work with and we definitely feel we got our money's worth. read more

Contacted SBLD/Kerry last week after trying to troubleshoot a persistent leak that our Flume monitor was reporting. Having done one pass earlier with another well known leak detection company with no success my expectations were rather low but with water leaking away ignoring it was not an option. The other companies leak detection tech seemed to be more interested in making a quick getaway rather than staying and owning the debug process. SBLD/Kerry arrived before our scheduled slot which is a great way to make a good first impression. My gardener had already identified a potential area where the ground was over saturated. It is always great when someone is not trying to redo a process of elimination to work up billable hours. Kerry worked off that info to quickly came up with a triage plan using a combination of some great acoustic leak detection tech as well as injected pressurized gas into the hose bibs to determine possible areas to focus on. I liked how cautious he was with making sure we were not injecting into places where you may cause more issues/His contract clearly states that to be a possibility but he was super careful. The leak/s landed up being a cracked underground 1-1/4" PVC irrigation supply line (buried 18" below) as well as a faulty sprinkler valve with roots burrowing into it forcing it to stay open. It has been a thrill to watch the zeros on the Flume monitoring after trying to chase this down for over a year. Underground leaks are not just pesky but require a patient and competent troubleshooter and debug time on larger properties. Leak detection tech is expensive but worth spending the $$ with real professionals. Kerry/SBLD are your guys. read more

Kerry was very professional and easy to work with. I had a backyard underground water leakage for a while, and was very hesitating to call large detection companies after seeing their extremely high price and very low star ratings, and I was told they might not be able to find the leak in even 10 hours. I tried to call Kerry, and he gave a reasonable price, came on time, and quickly found the leaking point in just 1 hour. He was also very kindly giving me a free hour if there is an extra leak. It's already fixed now. I am very impressed on Kerry's works, and wouldn't hesitate to call him again if there is any other problem in the future. read more

I am so glad that I called South Bay Leak Detection. Kerry found a leak in my pool when another leak detection company couldn't. I highly recommend this leak detector, and he will be my go-to person if I ever have another leak! read more
