Billy and the team at Duwamish Plumbing are my go-to choice for any plumbing project, big or small. As a real estate agent, I’ve worked with many contractors, but Billy stands out for his reliability, expertise, and professionalism. He often joins me at property inspections to provide a second set of eyes, and his insight has been invaluable time and time again. Billy is always prompt, honest, and direct, which makes working with him a seamless experience. Beyond his professionalism, his work ethic and attention to detail set him apart. He genuinely cares about the quality of his work, and it shows in the results. Over the years, he’s handled everything from installing all-new plumbing systems to troubleshooting complex issues like my pool pump system—and he’s always gone the extra mile to make sure the job is done right. His pricing is fair and transparent, and I know I can trust him to provide top-notch service every time.

I highly recommend Billy. He did all the plumbing on my recent bathroom remodel which included the installation of a new toilet (wall mount) 2 sinks and a shower/tub. He was knowledgeable, respectful and always on time. Following the remodel, I found myself reaching out to Billy for some emergency work under my 60 year old house. He has since replaced sewer lines, a leaky water line and is in the process of replacing the dryer venting that is no longer up to code. If you are looking for an experienced, friendly plumber that genuinely cares, you should contact Billy at Duwamish Plumbing.
