Rafael A and Keenon did an excellent job! They were knowledgeable, fast and precise. They explained everything in detail and were professional, yet down to earth. They were very clean and didn't leave any mess behind. I was even provided with an inspection of my toilets and sinks to ensure they were in good condition! They have definitely earned my business for future projects. Thanks!

Our repair was sort of a non event--a loose pipe fitting which my tenant had simply tightened himself by the time Alec got there. But there was no charge for the trip out, which was very classy. Thanks!

After signing up for the Membership program which initially allowed us a discount on some bib work that we had done last year, we recieved a call from Olympic Plumbing Technology (OPT) stating it was time for our free hot water tank cleaning and home plumbing inspection. Our plumber Gaige came within the indicated time window and was VERY pleasant, professional, clean and well kempt in his appearance. Since my first call for the bib work, I've had two different plumbers from OPT work in my house and I would without hesitation have either of them both back. They do a GREAT job!!!

We had a house main water valve that wouldn't shut off and refrigerator water valve that was leaking. Rafael was very friendly, he did a great job on the repairs and kept the workspace in a manner that when he left, it was as clean as it was prior to the work. He also took time to answer any questions I had.
I have to admit that I have to wonder what the margin on the parts is. But, when I need plumbing services in the future I will be calling Olympic Plumbing Technology!
