Clearwater Leak Detection
Company Overview
We will arrive promptly to identify your water line leak. We use multiple methods to find your leak. Our advanced microphones can pick up the sound of water moving through pipes and escaping from underground leaks. We verify the leak's presence using helium gas. We pressurize your water line with helium and use a detector above ground to sense the gas escaping. We may also use acoustic tools to listen for gas escaping at the leak site. In addition to helium, we also work with other types of compressed air.
Once we identify your leak, whether through our efforts or another company's, your water line will need repair or replacement. This means less interruption to your routine, including work, by not having to engage several companies at various times for detection and repair. Sometimes, repairs can be postponed due to the necessity of marking utilities, inspections, or other location-related factors.
Our services include the replacement of your water line. Our specialties include pool leak detection, thermal imaging, smoke testing, and backflow assembly testing. For more information, please visit our website.

Recommended Customer Reviews

Simon was so knowledgeable and tried to tell me different things to try before coming out to the site.

Simon was a pleasure to work with. He had on time, great communicator, gave recommendations and imparted knowledge from his decades of being a plumber. The area he marked was exactly where the leak was found. He has a great personality and his demeanor immediately put me to ease as I knew I was in great hands. Multiple other plumbers recommended him for finding the leak and I'm glad I listened to them. If you suspect a leak and you've read your meter to confirm, your next call needs to be to Simon. I hope I never have another leak but if I do, I know Simon is the only plumber I'm calling first and not wasting time with others.

In August 2024, I was notified by my water district that I may have a water leak. I did the checks and sure enough it looked like it was in the water line from the meter box to the house. I located several businesses that do leak detection and requested service on-line. I did not hear back from any of them. I tried a second time and Simon, owner of Clearwater, responded the same day. He came to my house, and I showed him the meter box and he said it must be a small leak by how slow it was moving. The meter box is about 130 feet from the house. He did his testing and located the leak about 5 feet from the house. He said it would probably be copper pipe and a small leak. He recommended a nearby plumbing company, Trident in Monroe, and I called them and everything Simon said came to be true. Simon was great to work with, professional, very easy to communicate with and his recommendation was excellent. His price was reasonable, and I would not hesitate to recommend or use his services again.

Simon came out to my home precisely on time, despite the rain, and helped me determine the potential causes of my water leak. It was a tiny leak, and Simon advised us that detecting the issue would take hours and not be worth it. I was impressed that Simon put my interests above his own when advising me on the issue. I highly recommend Clearwater Leak Detection.

I called Simon at Clearwater Leak Detection after being robbed for $108 by Appollo Plumbing who did nothing but try sell service contracts and wanted $1200 for Leak Detection. Clearwater answered my call and asked lots of questions and told me the exact price (half of what Appollo wanted) over the phone. He was busy but fit me in 2 days later. Arrived on time and went to work. Explained everything to me. Within an hour, he located my two leaks. He was accurate and the main leak was right under where he flagged it. I wouldn't use anyone else.

I had a leak in an external water line on my property and needed to find a good leak detection company. After doing a general internet search, and then reading highly positive yelp reviews, I hired Simon from Clearwater Leak Detection. I would HIGHLY recommend Clearwater Leak Detection for the following reasons:
1. SCHEDULE: Simon called me back quickly when I first reach out to discuss my leak. He was on time for both the leak detection and leak fix, which I sincerely appreciated.
2. COST: Even though I had far more than 200 feet of water line, he did not double his price for the leak detection (which he certainly could have). As a person on a limited income, this was truly helpful to my finances.
3. EXPERTISE: In my discussion with Simon, it was clear he has deep knowledge of his craft and he was communicative in helping to explain where the lines traverse, and where he believes the leak was.
4. LEAK FIX: He had to dig about 2.5 feet down around the water hydrant and when he found the leak, he had me come out and view the issue. He filled in the whole with additional drainage gravel, installed a new hydrant, including a wood block for stability (that should have been there in the first place) and then put back the pieces of ground he cut out such that you could hardly tell any work had been done - very impressive!
Simon is a kind and personal professional and I would HIGHLY recommend hiring him for his superior knowledge, integrity, and professionalism. I would not hesitate to hire him again should the need arise. His contact information is: Phone: 206-686-9300, Website: clearwaterleakdetection.com.

We are new homeowners and still figuring out the quirks of our house. Everything weird and new is scary and daunting and we automatically fear the worst, so when our neighbors came to our door late at night a few days ago telling us there's water gushing from between the cracks in our driveway we started to panic.
We tested everything to see if our water pressure was impacted (it wasn't), turned off our main water to see if that helped ease the flow of the fusing water (it didn't), and called a plumber the next day. They said while they could fix a broken pipe, they weren't the right people to find a broken pipe and referred us over to Clearwater Leak Detection.
We called and left a message in the late afternoon on Monday and heard back from Simon Wednesday morning. He was able to squeeze us in the same day, provided us with a verbal quote, and worked with us on a time that was mutually agreeable (my partner and I both had meetings we couldn't miss or reschedule... when it rains it pours, am I right?)
Simon provided great communication throughout the day to gain additional context for our issue and arrived on time. We were greeted by a smile and a handshake. He immediately spotted where the water was still running, as by this point it was down to a notable trickle.
He helped us locate where our water meter and steer shut off were, tested our water pressure and checked our neighbors meter as well to see if it was perhaps coming from their side. All turned out well, and it was determined that it was ground water running under our driveway. This was the news we were hoping for as we're located on a hill and haven't noticed this issue before when it was dry.
Simon was quick and efficient, gave us some suggestions on possible solutions but was honest and gave us realistic likely outcomes (i.e. we can spend a bunch of money to maybe reduce/eliminate the issue but it probably won't work). While we still have some thinking to do on next steps, we at least have the piece of mind that our pipes are still in tact and our water usage isn't impacted at all.
Massive thanks to Simon for the quick reassurance and fitting us into his schedule. 10/10 for sure. While we hope to never need these services again, we know who our first call will be if we do.

Our water company came to us and let us know that we had a really bad leak somewhere (water meter was running ~1 cubic foot per minute). After a quick check inside with nothing obvious, I called around and was pointed to two options, American Leak Detection and Clearwater Leak Detection. I called both but American never returned my call. Simon from Clearwater chatted with me and said he could come by the next day.
He arrived the next afternoon and after I showed him where the meter and the water shutoff were he got to work. He used two different techniques to help locate the source of the leak, both of them leading to the same area in our easement. He marked the area clearly, showed me where it was, and recommended next steps for me to take. He even helped me with a separate question for something inside the house which he had a special infrared tool for.
Simon was very transparent about his pricing and gave me some leeway when I underestimated the distance from the house to the water meter. He's very knowledgeable and identified the issue quickly. He shared his contact information for plumbers who could help repair the leak but was transparent in letting me know that their schedules were full for a few more days, and to look around for a sooner option. Overall we were very happy with Simon's services and would definitely go back to him in the (hopefully distant) future.

Writing to say that Simon at CLD was amazing to work with. He was completely professional and extremely polite. He took the time on the phone to diagnose possible issues, came out and met with us and isolated the problem area and came back to do an incredible job fixing the leak.
Highly recommend Clearwater Leak Detection to anyone. You will be very happy with them.

The water company let me know I had a leak but my plumber could not find it. Clearwater was able to come out quickly! He checked everything and found the leak was under the foundation under my washing machine.
He marked everything so the people fixing it could find the leak. He gave me an idea what it should cost to fix which was great as I got one estimate that was really high so I knew to keep looking.
I was also able to text and ask more questions and he was awesome about responding.
I would highly recommend them!
