Clearwater Leak Detection
Company Overview
We will visit your property to locate the leak in your water line. 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. To confirm the leak's location, we also utilize helium gas. By pressurizing your water line with helium, we can use a surface detector to find the gas. In some cases, we utilize acoustic devices to detect the sound of gas escaping from the leak. Besides helium, we employ different types of compressed air for leak detection.
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. There may be delays in repairs due to utility markings, inspections, or other factors depending on the location.
We can handle the replacement of your water line as well. Additionally, we specialize in pool leak detection, thermal imaging, smoke testing, and backflow assembly testing. Visit our website for additional information.

Recommended Customer Reviews

Simon was outstanding. We have complicated plumbing here in a turn of the century house. He solved the puzzle and found the leak that was causing big problems with our water bill. He explained what he was doing, why and how. He is very professional and courteous. I would recommend him without exception. You will not be disappointed.

I had a leak somewhere between the meter and my house so I called Clearwater to find it. He came out quickly, found the leak in a little under two hours, marked everything off, and gave me a referral to a plumber who could fix it, and his price was fair. The news was bad (I needed a whole new line put in) but that's not his fault!

I had a leak somewhere along a 200 foot line from the meter to the house. Clearwater came out and spent about 30 minutes walking up the line marking its path. Eventually they drew a 4 foot square box and a tot in the middle. He said 'its should be about one foot from the center'. Couldn't have been more accurate. I dug the whole myself, about four feet wide and four feet deep and found the break in the line. It was exactly on center of the leak detection box. Couldn't have been happier not to spend days digging holes and instead dug just in the correct spot. The plumber came out and only charged me $350 to cut and repair the pipe. (other plumbers wanted 3k to fix or 10k to replace the water line) Using Clearwater to locate the break saved me thousands of dollars.

I called Clearwater recently and Simon ended up saving me thousands of dollars by correctly surmising that some very light, trickle-level flow that I had was not a leak but a different problem entirely.
Simon has expert-level knowledge on leaks and is very familiar with the intricacies of the Seattle water system; moreover he is very personable and patient in explaining the details of the detection process. I'd recommend his services to anyone.

After receiving a water bill over $500 for my rental house, I had my son call Clearwater Leak Detection to locate the leak. Simon gave us the time he would be out, and was at the residence as stated. He explained the process he would use to locate the leak and what his charges were. He promptly went to work and after a few hours he located the leak in the main water line. He stated he could fix it and gave me a price that was reasonable. He set a time to do the repair and again arrived as state with all the equipment needed to do the job. After digging a very large, deep hole, he located the leaking line exactly where he stated it was and replaced the leaking section of the line, that had been repaired 3 times before with hose clamps, with a new section of water line with brass fittings. He was at all times Friendly, Courteous, Knowledgeable and Professional in his work. I would not hesitate to call Simon again or recommend him to anyone that would need his services.

1. Quality work
2. Fair price
3. Showed up when he said he would
4. Did what he said he would do
Had a leak in my water pipe coming from street to my house. He detected the leak underground and had me good to go by the next day. No B.S., clear and to the point.
He is now my go to leak detection guy. Thanks Simon !

Called to see if they could come out and do backflow testing and they said they are too busy and not accepting new customers. So I guess they are 5 star for existing customers only. 1 star and will never call them again

City left a message on my door about a possible water leak. After trying unsuccesfully to find the leak, I looked for a plumber here on Yelp and decided to call a company called ""Good Plumber"" and recommended Simon for the leak detection. Spoke with Simon and the next day he was here at my house. He was on time, very nice and would fill you in on what he's doing while checking for the leak. He was done in less than 2 hours. The price was $375, which was reasonable, for a minimum of 2 hours. He was able to find the leak and I ended up calling Good Plumber back who also did a very good job! I will leave them a separate 5-star review as well.
I hope to not have any water leak issues again in the future. But if ever I do, I will definitely call Simon again!

Very happy with Clearwater Leak Detection company service. We had a main waterline leak on Friday afternoon, flooding the neighborhood. When I called the company, Simon, the owner agreed to come out to identify the leak on Saturday morning. No other company in the area was willing to do the job over the weekend. Simon was prompt, professional and found the issue within an hour. He also recommended most cost effective option to fix the leak. Thank you for a great service and will recommend you!!!

Great service! Knowledgeable and helpful! Very friendly and on time!! Hopefully I do not have to call again but if I do I will definitely call them!
