Best Test And Repair in Seattle WA

We've used Clearwater Detection several times as our water line was not properly installed when the house was first built. Simon always comes to the rescue from detecting the leak, digging & finishing. He quickly detected today, what we thought to be a water line leak only to find that it was a running toilet in our detached garage apartment. Always great work, thank you!!

Excellent service, staff is friendly and knowledgeable!

Sewer Friendly replaced a damaged sewer pipe in my front yard and had to excavate to get access. The team finished ahead of schedule and did a great job filling back the hole after the repair. Thank you for the excellent work!

Nick was prompt, efficient and personable. He identified quickly the parts that were missing from the box of the new faucet I wanted installed. Wasting no time, he turned to installing just the toilet and was in-and-out in no time! Thank you, NIck!

We had a leak in our attic pipes and Evan came out and fixed it. While he was fixing it he found a leaking hose bib and replaced it right away. Good quality work and we will definitely be hiring him for any future plumbing jobs! Highly recommend Evan!

I called several plumbing companies to find same-day service (even though it was not the worst emergency), and Mr. Rooter came through. Prompt and professional service. Cost acceptable although I don't know enough to compare. The tech had everything he needed to complete the job with one stop, which we appreciated. We'd call again.

Friendly and helpful staff! Very advanced business model.

Our sewer backed up the day before Thanksgiving and David and crew came in the day after Thanksgiving and cleared our sewer and then installed a liner. The whole crew is great, professional very responsive and helpful, they even loaded a generator into a trailer for me. Wonderful people, great professional and timely service and cleaned the area after they were done to be cleaner than when they started.
Thank you David and crew you are great.

I bought a fixer upper in Seattle that required significant repairs. I got a few quotes for some projects from plumbers in the area and NO ONE was as nice, professional and respectful as Zach and the team at Knockout. I am so impressed with everything they have done around this house to make it that much more liveable! I have already recommended them to everyone I know, will continue to do so, and will absolutely be back if I need more help! Thank you!!!!!!!

Bryce was very efficient and clear with us about all of our options for service. He explained the whole process very clearly and showed us exactly what was being done and the final result of his work. We were very satisfied.
