    Be very careful choosing this company. They are only concerned with THEIR time, THEIR costs. They are NOT interested in customer service.

    Absolutely excellent service from real professionals who know their trade…read more I had been calling various plumbers to fix a toilet leak, and most of them made the situation feel more complicated than it needed to be. When I called Salish, the owner, Dustin, calmly helped me identify the likely issue over the phone, and we were able to schedule an appointment for the next day very easily. Nathan and Wade were the plumbers who came over, and they were respectful, knowledgeable, and efficient. They finished the job quickly and even identified another issue in the house that I hadn't noticed. Honestly, they were pretty reasonably priced considering the area, and at the very least, they were clear and upfront about their rates. Great business. Absolutely recommend.

    VERIFIED THE BEST! The City of Mercer Island sent notice that we needed a backflow test. The notice…read moreincluded a list or 40 companies that were approved by the city. I loaded all 40 of them into my Claude AI program and asked the AI to tell me which one was the best. Which one had the highest ratings and had no bad feedback. It came back stating that 5 Star Backflow was the BEST of the 40 approved companies! I then called Josh, the owner of 5 Star Backflow, and he and his team worked around the clock to help me because I was up against a deadline. His communication with us was spectacular and thanks to him our water did not get cut off. We even had a complication with the backflow valve being broken, but he got it taken care of and he went way above and beyond to help us. I wish I could give him a 100 stars, because he is the real deal and he deserves a great review. If you need a backflow company, 5 Star Backflow is the absolute best! Thank you Josh!

    I've been using 5 Star Backflow Services for my required city backflow inspections for years now…read moreand I've always been happy with the service, so it's probably time for a review. Once they had me in their system, they started contacting me in advance to schedule the test each year, which I really appreciate since the city notice doesn't usually give a lot of turnaround time. This year the city surprised me by sending the notice a month early, and I was on vacation when the notice came. This left me with just over a week before it was due. I contacted 5 Star Backflow Services and they were able to do the test just a couple days later. After the test they always send the report directly to the city within 24 hours. I have been very pleased with the service. Thank you!
