Clearwater Leak Detection
Company Overview
Our team will come to your location to detect the leak in your water line. We employ various techniques to pinpoint your leak. Our sensitive microphones can hear water movement within the pipes and any leaks that may occur underground. Helium gas is another tool we use to ensure we've found the leak. 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. We use various forms of compressed air alongside helium.
Once we identify your leak, whether through our efforts or another company's, your water line will need repair or replacement. This minimizes the disruption to your daily activities, including work, by avoiding the need to hire multiple companies at different times. Repairs may be delayed by the need for utility markings, inspections, or other location-specific requirements.
We are also equipped to replace your water line. Additionally, we specialize in pool leak detection, thermal imaging, smoke testing, and backflow assembly testing. Check our website for further details.
Simon has over 25 years of experience, having owned his own business since 2007, which equips him to effectively diagnose your water line and the leak's origin. With over 15 years in municipal water system management, Simon has extensive experience in the field. Clearwater Leak Detection holds a license (CLEARLD891JG) and is bonded in Washington State.

Recommended Customer Reviews

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!

Found out about a wet spot in a guest room today, did a search here on yelp and found this company at the top of the list with good reviews. So I decided to call, and since I was calling around 8:30pm, I was expecting to leave a voicemail message...but Simon (the owner) answers the phone! Wasn't expecting that! haha!
Though it was around dinner when I called, Simon took the time to address my concerns, provided his recommendation and price quote. Going to have a plumber take a look first, but if it turns out that I'll need his service, I'm definitely giving him my business!

Great service. Came faster than any other would and was priced near or lower than a few other quotes. Also recommended some good plumbers for the job.
