We had a full sewer replacement that required an entirely new trench dug, new pvc pipe and retro fitting of old pipes from the house. Our experience was amazing, Ron, Vernon, Garrett and Morgan served us on this job. Everyone was very professional, courteous and knowledgeable. All of our questions were addressed with honesty and there were no surprises along the way. The work was completed with great efficiency, with care and the city inspector praised the completed job as "above expectations". Olympic has made a customer for life and we will truly endorse them for any job to our friends and family. Thank you Olympic Plumbing!

Jake came out to help us with a leaking bathtub. He was helpful and knowledgeable and very friendly. This was our first time having a “significant” plumbing problem and he a great job of helping us understand the problem and give us a path to fixing it. He helped the situation immensely by breaking down the issue and making sure we fully understood what was happening. He also helped connect us to a restoration company to address the moisture issues, citing the importance of solving this problem beyond just the scope of his work. We look forward to working with him again!

This company is great. Our three experiences with Sean have been great. He was prompt, professional, and courteous. Installation was done in a timely manner and Travis helped us with a couple of small repairs. When the job was finished the cleanup was excellent. We would highly recommend this company.

I called and was given a time slot of 3 - 7 pm even though everything was booked for the day. 10 minutes after I had called, I received a call from a technician and he said he was on his way and could be there in 10 minutes! Awesome! Two trucks pulled up and two technicians. We all got along great and had discussions outside of plumbing that were enjoyable. They assessed the main issue and did a full inspection of the plumbing inside and outside the house and poited out the things I needed to keep an eye on. My main issue was the outside hose bibs were leaking and were basically shot (35 years old.) Cheaper to replace than repair. They gave a quote, I signed, and they quickly got to work and completed the job in timely fashion. Thanks guys for your work and especially your friendliness and conversation!

We had Olympic Plumbing Technology come out and replace our old kitchen faucet with a new one that we supplied and the three angle stops. Morgan did a wonderful job; he was very professional and knowledgeable. There was a small pin hole leak in the short supply line pipe threads for one of the angle stops that was hard to stop. He ended up replacing the pipe at no extra charge. He finished the insulation and thoroughly cleaned up the area. Thanks, Morgan, for a job well done.

Danny was excellent. I actually ended up resolving my own problem right before he arrived. But, he was still willing to do a quick inspection of my work on my water heater and make sure it was truly resolved with no cost to me for their drive over / dispatch or inspection. Very personable, communicative of the ETA, and would be happy to work with them again if I ever needed to.
