Thanks Jake Roderick! Fixed my disposal quickly and walked me through other plumbing things to keep my eye on as a new homeowner.

I can't say enough about how pleased I am with the service provided by Gaige and Skyler. Professional, personable, and on-time. I was especially impressed by Gaige's encyclopedic knowledge of on-demand water heaters. He evaluated and explained the problem, then laid out all the options available to us without trying to sell us on any one of them. I'd give these guys six stars if I could!

Gaige S. kept in touch about his delayed arrival. He had a pretty good idea of what was wrong with my noisy tankless water heater. He was right, and the pesky problem was fixed in minutes. Excellent service, great communication, and a very personable guy. I'm glad I have a service contract with Olympic Plumbing.

I had nothing but a positive and professional experience with Olympic Plumbing Technology. We discovered a leak in our crawl space and they got a technician out on a Sunday very fast! The fix was completed by Darin and Jake who where on point, professional, and friendly. Hopefully we won't need any plumbers anytime soon but I would call upon Olympic Plumbing Technology again.

My water heater died over the weekend and after troubleshooting it myself, I knew it needed replacement. After calling Olympic Plumbing, Darin was sent out to assess the situation and performed a safety inspection of my plumbing. He agreed with replacement and explained the possible causes for the water heater ultimately failing. The following day, Darin and Jake swapped out the water heater, improved the piping situation and somehow made the furnace room looking better than it did before which is an absolute plus! Whoever had done the plumbing in the house previously had done a terrible job. Great experience overall!

Scott is a thorough diagnostic. He evaluated for my first concern (toilet leak), and found a connection error an A/C company made. I then showed him the bad plumbing work on my water heater, and he corrected it. He is friendly, energetic, efficient and a gentleman
I am, again a pleased customer. He also did the plumbing checkup throughout my home.
