    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!

    While the field backflow testing service itself was adequate, the company's back-office operations…read moreare poorly managed and unacceptably disorganized. Their reminder system is not aligned with municipal requirements, and their billing and accounts receivable processes are fundamentally flawed. I was repeatedly told by staff that a prior invoice had not been paid, despite the fact that I retained written confirmation showing the payment was submitted through their Intuit QuickBooks link and acknowledged with a "thank you for your payment" email. Despite providing this documentation, the company unilaterally canceled a scheduled service appointment the day before it was to occur, citing non-payment. When confronted with proof, the explanation shifted to a claim that they "never received the funds from the credit card company," which is not a defensible position to place on a customer after confirming receipt. These outdated business practices, inconsistent internal communication, and lack of basic financial controls introduce unnecessary risk for clients. While I had initially intended to continue using this company, the operational failures and resulting service disruption make them unreliable and difficult to do business with. There are other providers who can deliver the same service with greater professionalism, transparency, and reliability, and I will be pursuing those alternatives going forward.

    I don't recommend this company to anyone. I used them for over 7 years for two properties with 5…read moredevices in total. This year due to an emergency situation that I needed to go to hospital, I couldn't keep my appointment. I asked Loren Hanson, the owner, to reschedule the test date for me, he replied by saying 'we don't work for you any longer! Loren has no appreciation of customer royalty.

    Overall I think responsiveness, timeliness, and completeness there were nothing wrong at all. I…read morerarely cross over outside of reviewing restaurants but This time I had to leave a review. After the work was completed, I was told the report would be sent to the city and I would get an invoice later for the work since there was an additional device that needed to be tested. I of course said ok and thought nothing more of it. Fast forward about a month later. I had already forgotten this issue since I was expecting an email. I get a letter from the city saying my test was incomplete and that my water will be cutoff soon. I called back and was told they had forgot to submit the report and they would do it ASAP. There were no mention of the second device cost so I thought maybe they were going to throw it in for free since there was a lateness. I of course then get an email with the invoice for the additional device and finally a few days later I think I was cc'ed on the report sent to the city. Now, if I had been out or didn't check my mail for a while I really could have my water turned off and I think that even affects my credit? That's not good.

    Fantastic Experience!…read more Needed a backflow test completed, as we were late by a week according to the city. Scheduled an appointment with Good Guy for Friday, and then I sent an email asking them to come earlier, if possible. They got back to me in an hour, and confirmed they could make an earlier appointment for me! Super cool service, super easy, and well worth it! I would use Mac again in a heartbeat!
