The very best - Colin Marcee and Pacific Coast Leak Detection did a great job of finding and repairing the leak in my pool. He did this at a very reasonable cost in just two visits. read more

Colin was great! He went above and beyond. I thought I smelled mold in the home and he checked out the interior and exterior of the home and did a pressure check on all the plumbing. He investigated the source of a minor occasional drip under the sink ( not where I smelled the mold) and a checked out a defunct water heater. He concluded that the mold smell was coming through the open window from the garden, and in fact the smell was stronger out there. Because he found no area of concern, he gave me a significant discount! Thanks, Colin! read more

We had Colin Pacific Coast come out and do a leak detection due to some detected moisture in our walls. He was very professional, personable & thorough. You can tell he cares more about helping his clients rather overcharging ppl to get some work done. Prices were reasonable & I would highly recommend them! read more

Colin did a terrific job identifying and repairing my pool pipes. Highly recommend. read more

After seeing several great reviews on Yelp and noticing how Colin responded right away to their questions or concerns, I felt good about trusting him to be concerned about a leak in my pool line as well. Colin fit me in to his schedule the same day and helped me make the best decision for my particular situation. He is very knowledgeable and helpful and I will definitely give him a call for future service. Thank you Colin. read more

I was concerned abut my pool leaking so i reached out to Colin. Communication was straightforward, and I scheduled an appointment even though his quote was a lot higher than the other companies that got back to me. Im so glad i did because this guy knows what he's doing and is honest. I've come across a lot of flaky people in the pool business. Colin didn't seem that way at all. Got a text when he was en route and he showed up during the scheduled time. After i told him my reasons for suspecting a leak and his initial assessment of my pool and equipment, Colin didnt think i had leak or needed an in-depth inspection. He proceeded to spend another 15 or so minutes inspecting my skimmer and pool equipment. He spent another 10 minutes educating me on pool leaks and what to look out for. He refused to charge me anything for the visit even though I insisted I compensate him for his time, gas and expertise. Thank you again for sharing your time and knowledge! I know who to call or recommend when it comes to leaks. read more

We are new pool owners and have nothing but positive things to say about this company. We called Pacific Coast Leak Detection because they had great reviews here. They quickly returned our call and showed up later in the same afternoon. Their rates were reasonable and they took the time to explain what they were doing and how we could mitigate future problems. Collin has integrity and a wonderful work ethic. We would highly recommend his company to anyone that thinks they may have a water leak on their property (pool, plumbing, etc.). read more

We called our leak detection specialist Colin because we have bubbles coming out from one of the return jets. We also noticed the pool water level was going down. As usual, Colin arrived on time and ran some tests. He found a leak in the suction line, next to the pump. We scheduled another appointment to fix the problem. I'm endorsing Colin again because he's very trustful, skillful and honest. read more

I was very pleased with the service provided by Pacific Coast Leak Detection. Colin was very responsive to the concern and was able to detect the leak in the pool. It was very reasurring to have a knowledgable person on site who offered solutions and reliable testing information. I am so relieved to have this resolved and highly recommend their service to anyone in need of leak detection. read more

Colin came out to check my pool. He ran multiple tests to figure out where the leak was coming from. He figured out it was from my pool skimmer, so there was no need to cut into the concrete. They're a few good honest contractors out there an Colin is one of them. I highly recommend him read more

Colin is my hero. I woke up at 6am on Mother's Day to pounding on my door. A dog walker noticed I had a broken pipe in the front of my house and water was running down the street. I reached out to Colin and he was on site and issue resolved by 10am! He walked me thru the issue, fixed it, left me with his card and some guidance. His services were reasonable. I really appreciate his helping me in such a timely manner on Mother's Day. I highly recommend Pacific Coast Leak Detection! read more

The water level in my fiberglass pool was dropping about 2 inches everyday. I sent a message requesting a quote through Yelp and Colin responded within a few hours. He provided the cost, the details of the leak detection process and scheduled a visit 2-3 days later. He arrived promptly and completed the comprehensive leak detection process and explained the results. He found a problem with the sweep line. On pressure testing the sweep line, he found it was losing pressure. Upon further inspection he found a crack in the wall fitting glue joint. The area was dye tested and a leak was visually confirmed. Colin scheduled the repairs (within 5 days). On the day of the repair, he explained each step, providing updates as he worked. The bottom line is that Colin is professional, friendly (with many stories, which I enjoyed), and his prices are competitive. I recommend Pacific Coast Leak Detection, Inc. Thank you Colin for the great work! read more

We had a leak that would reveal itself on the sidewalk flowing from the edge of our lawn. I knew it was under the front porch patio because the immediate lawn area seemed to always be saturated, and was very soft to walk on. That, and high water bills, we decided it was time to get this fixed. I put a blast on Yelp and was able to speak with a few plumbers, who recommended hiring a Leak Detection Specialist since it was possibly under concrete. They also explained how typically and frightfully expensive such a job would cost. Unfortunately, it had to be done. In my research, I found the routine well known big companies who perform Leak Detection, but also found a newcomer in the business called Pacific Coast Leak Detection. Pacific Coast Leak Detection seemed to have just been established with no reviews yet on Yelp. In typical fashion, I was like, "What the Heck!" and gave them a call. I spoke with Colin Marcee, who is the owner and operator of this new company. Upon speaking with Colin, I learned that he had over a decade of experience in this field with many of those years at the big detection companies. He is also scuba certified so he is able to find and service leaks in pools. He took the time to answer all my questions and explained the leak detection process along with what to expect. I made an appointment with him and he was able to come by that afternoon. At the appointment, he went over the details in the process of finding the leak and what the repair would entail if it was under the concrete. He was very honest, easy to talk to, knowledgeable in his field, and reassured his ability to pinpoint the leak. He went ahead and pressurized the waterlines and proceeded to listen for the leak with his specialized detector. After listening in for a bit, he marked an "X" where he suspected the leak was. Unfortunately, it was under the concrete, as I had dreaded. At this point, the leak detection part was complete and I had the choice of going with a company of my choice for the repairs or have Colin go to work on the leak. I chose the latter and I made an appointment with Colin for the following day. The next day, Colin arrived to our appointment as scheduled. After setting up, he attempted to go through the dirt and dig under the concrete in hopes of saving time and money by not going through the patio. Unfortunately, it was not accessible and demo needed to be performed. He went through the concrete and dug out the area to discover the leak was EXACTLY where he had placed his listening sensor, as can be seen in my picture upload. He made the repair to the separated PVC joint with a series of right angle fittings to relieve potential torsional stress typically experienced with a single joint, which seemed to be the original cause of the leak. Then, he retested the waterlines and the pressure was holding steady with no drop off. Colin then backfilled the repair area and packed and leveled it with sand before finally pouring the concrete. In addition, he applied color to the mix before pouring and finishing with a brushed texture in attempts to match the original concrete as close as possible. When all was said and done, the final cost of the project was VERY reasonable, even undercutting the quotes I was receiving from the plumbers by more than a third! I must say that I am Very Happy with this experience. I am very glad I called Pacific Coast Leak Detection and am delighted that I can give them 5 Stars on their first Yelp review. Hopefully, we will never encounter another issue where we will require their services, but in the event that we do, Pacific Coast Leak Detection will be our first call. read more

Had a pool leak at an unidentified location. Colin came out performed all of his testing but couldn't find the leak. We came to the conclusion that the leak was likely in the pool drain at the bottom of the pool so he put on his dive suit, dove down there, confirmed the leak and patched it with Epoxy. Very knowledgable and efficient. Highly recommend. read more

I saw Colins work first hand at a residence I service and I reached out to him about more work because he did such a great job. Colin responded quickly and made an appointment. He showed up on time and found our leak quickly. It takes a man time to acquire the tools and knowledge to be as punctual and thorough as he was. Thank you Colin -Mike. read more

I give Colin 5 plus stars for his outstanding leak detection service he provided at my home in Tracy on Oct 18. He went above and beyond to test my Pool waterfall system and help prove to my pool contractor that the system was indeed leaking. To confirm there was a leak was almost impossible other than the moisture spots that were visible on the stucco. He tested various things and finally one of his tests showed a water line that confirmed a leakage inside the waterfall wall. Thanks to his expertise and consistent testing I can now have my pool contractor fix this leak since the waterfall was just recently built and under warranty. Thanks Colin! read more

Great company! On time and completed the job in a timely manner and going up and beyond past his regular hours! I definitely recommend.

We had a leak in our pool so I called around to see what my options were. I sent a message to Pacific Coast Leak Detection and Colin responded quickly. He was very professional and accommodating. He was prompt to set up an appointment. Loved his communication via text to let us know when he was in route and everything was was in writing. He showed up right on time and the job was done efficiently and quick. I would highly recommend Pacific Coast Leak Detection. Great price also! read more

It's unfortunate that I had to call a leak detection company since my pool guy insisted there was a leak rather than noticing my auto fill was running constantly and that part needed to be replaced! The best part was that the gentleman from Pacific Coast Leak was so upfront and honest. I appreciated his frankness and at least I'm now sure that there's no leak. read more

If there is anybody out there that needs some pool repairs I highly recommend Colin Marcee! I don't think I have ever had a workman of any kind with the professionalism knowledge and friendly with such good business practices as Colin! We have had a leak with the pool for a couple of years now.... pretty obvious it was something to do with the skimmers and one company came out said yes it is the skimmers , gave us a price. Of course we got a second opinion on the situation Colin was recommended from another company that was way to busy, had just met Him and did not know to much about him. Colin came out the next day took a look at the situation gave us a price a bit higher then the other company, but because of his business friendly attitude we chose him. To make along story short when he started to prepare for the skimmers replacement He called my daughter and said, now that the water is down and I am getting a closer look at these skimmers let's try resealing them ,they seem pretty solid now that I can check them closer! If it doesn't work, but I think it will get you through for awhile longer at least through the summer months....If it starts to leak again let me know and I will deduct the price you are paying today from the skimmer replacement total! Who does that???? He could have just went ahead and replace both skimmers for the amount we had agreed on.... But He didn't to me that is a good business practice! So far the pool seems to be holding its own and it's been 3 days of hot weather I would be adding water again by now! Call Him if you need pool repairs! You will not be disappointed! I can add that the boys left their basketball hoop in the middle of the driveway and he took it upon himself to move it for me (no clue how I would've done it myself). While watching him do it, I quickly KNEW I would not have been able to do it AT ALL. As he was ready to leave, he believed that he had cracked the base of the hoop and apologized profusely. We told him it was no problem but he would not let it go. Instead, he moved the hoop back to a safer place and patched the hole he thought he made. He was a cool dude start to finish. read more

after reading so many great reviews about Pacific Coast Detection and colin we decided to give him a call the Monday before thanksgiving, he scheduled us in that week the day before thanksgiving no less, was early, efficient, honest, and just all around nice guy. In a world where a lot of businesses care more about the almighty dollar than the clients they are getting them from it's refreshing and heart warming to meet an individual that is knowledgeable, honest and has integrity and good moral values and who is not trying to rip you off. thank you colin so very much you restored our faith in humanity again (no exaggeration) read more

Wish I could give Colin 10 stars! This guy is fantastic. I had been losing about an inch of water in my pool every day for about a month. I found his company on Yelp by reading the all the great reviews. Called Colin on a Saturday about noon. He came out that night at 6pm and spent a couple hours doing the leak detection. He found exactly where the leak was (nowhere near any of the areas I thought it might be). He did the repair 3 days later and like "magic" no more leaks or water loss. He's very personable and explained the "process" thoroughly. Highly recommend his company for any of his services. read more

Colin saved the day! We had an emergency leak in our irrigation system and needed a new shut off valve to disconnect the irrigation system from the main line. Although not a typical job, Colin was able to help in a pinch and was able to disconnect the irrigation system from the main line so we could have water. We are very happy and appreciate that Colin was able to help! read more

Colin is a super nice guy. He did a thorough job of checking for leaks inside and out. He wore a mask and is very polite. I highly recommend this company. read more

Wish I could give more than 5 stars! We had an above ground plumbing leak on our pool at the worst possible time, on a weekend, and was flooding our backyard. Every place I called was closed, luckily Pacific leak detection was open! Colin came out on a Sunday to address the situation. He went above and beyond for us to repair the leak and we couldn't be more thankful. He was very professional, informative, and his pricing is very reasonable. Highly recommended! read more

Responsive, thorough, honest service. Tested all pool plumbing and equipment. Needed to wait for draining pool for new plaster to test main drain under more than static pressure because water was extremely cold. Leak was small and not obvious, and didn't draw dye. Colin made 3 trips to test at the original cost and didn't try to upswell abs he followed through. He also added temporary epoxy repair of possible contributing crack in plaster. read more

Colin was on time and on cost. The company is great at communicating with the customer and he took the time to run me thru all the scenarios to fix the issues with our pool. He was able to repair our issues in a few hours. The fix looks better than the original! Really appreciate his hard work and rapid response. Would recommend to anyone needing leak detection and repairs. Colin was COVID aware and followed all the proper protocols when at my location. read more

Colin was awesome! We had two companies assess a slab leak under our kitchen island and we ultimately decided to go with Pacific Coast Leak Detection. I'm so glad that we did. Colin was able to locate the leak and fix it without a full tear out of our kitchen floor. He only recommended what was absolutely needed unlike the other company. He was easy to communicate with and he even kept in direct contact with our insurance adjuster as needed. Colin was very professional, empathetic to our situation and respectful of our space. Colin, thank you for your responsiveness and for helping us restore water to our house as quickly as possible. read more

Colin is fantastic! From start to finish, he was incredibly professional and helpful. He identified and repaired our water leak by our pool and we're now saving $200 on our water bill. Highly recommend! read more

Great communication and quality work. Easy to schedule and now the pool doesn't leak anymore. Thanks so much! :)

Colin Marcee was terrific right from the beginning. Received a quick response to my first call, came out the next day to give an estimate. He is polite, professional and very knowledgable. While a number of pool guys told us the leak was in the skimmer, Colin brought his many detection tools and determined it is a break in some spa jets near the stairs. He dug up a small area, replaced the pipe, closed it up and re-covered the area (with the exact matching material) and the pool no longer leaks! A professional leak detection company is a MUST. We came very close to hiring someone who wanted to charge us to replace the skimmer and we would have paid a lot of money and still had a leak. Thank you Colin! We couldn't be happier with your service!!! read more

I went into hiring a leak detection specialist with hesitation. Pacific Coast Leak detection has many 5 star reviews and Colin earned every one of those including mine. Professional, efficient, communicating clearly and explaining everything throughout the process. If you are hesitating, don't. Just hire Colin! read more

CALL THEM!! You will not be disappointed. Literally so glad I read the previous reviews. Collin is absolutely amazing so understanding and personable. The reality is not everybody has infinite amount of money to fix things right away. His prices were so reasonable. I called four different companies for leak detection and all of them wanted to charge me upwards from $600-$900 for leak detection only. At that Point I was like let's just drain the pool until the finances are available. I literally had done everything I could personally. He came, on time, communication was more than five star. Just genuinely a good person. Found the leak, I had an estimate in my email maybe an hour or two later. Again VERY reasonable. He will be my go to for every pool repair I need from here on out. Seriously he's your guy. Pool leak detection and repair. Thank you again for amazing service. Sorry no pictures available because I was at work during repairs. read more

Nothing more frustrating than finding an empty spa each morning. My pool service, along with two other pool repair services, could not determine the cause. I was told that I needed to contact a leak detection company to do a complete inspection of my pool and spa system. I contacted Pacific Coast Leak Detection and was immediately scheduled for an appointment the following morning. Colin arrived on time and jumped right in to search for the culprit. All the testing on his first visit turned up nothing. He returned the following day and continued to test. After several hours, I felt like we were at another dead end and I was ready to move on to another company, but Colin persisted and located the cause of the 'leak'. A failed check valve that others had overlooked. I have never seen someone so dedicated and insistent on getting to the root cause of the problem. Hats off to Colin and Pacific Coast Leak Detection for their superior service! read more
