John Smintina

We replaced both the main shutoff valve and PRV. Great quality work at a fair price!

Sam Brown

We used 5 Corners Plumbing as a trusted third-party inspector for some Warranty work that came up on one of our projects. The shower pan test they performed was able to identify the point of failure that was causing the leaks the client was experiencing and set us on a path to resolution of the issue. Much appreciated 5 Corners, your knowledge and fast response was Awesome and Juan was a pleasure to work with!

Doug C

Was really pleased w 5 corners. Very much appreciated estimates via telephone and their pricing for buying toilets was comparable w online sites. Installed 3 bidet toilets that we also purchased from 5 corners

Leonard Fusselman

Emailed me immediately over the weekend and gave me a quote. Showed up, did the work, and the final price was close to the quote. Great company

Peter Beissinger

Great experience with them! Booking was straightforward and timely, and our technician, Juan, was a very pleasant guy who completed the work efficiently and without issue. They were also very knowledgable about the details and extra requirements of the particular Toto toilet/washlets we were installing, and helped me catch a few missing pieces on my end, saving us all time and headaches. Very glad I went with them instead of some other non-Toto-Certified plumbers

GC Property Service

Kenji explained everything in detail before providing the job estimate. Juan did an excellent job replacing two valves in my client’s home. He was professional, efficient, and made sure everything was working perfectly before finishing. Highly recommend this company!

Yishai Galatzer

Kenji has a phenomenal interaction with me as I was trying to figuer out which and how to install a new Toto unit in my condo. Not only he was knowledgeable, he had infinite patience, was straightforward, and guided me to a solution. By far the best interaction I ever had with a plumber/Toto expert.

Greg Braden

Overall: great and fast service, transparent pricing, plumbers had great "bedside manner" and did not try upselling or hard selling. We had a leaky toilet and 5 corner's owner gave very fast response to my email query for repair or replace options. I had an interest in replacing the faulty toilet with a new super-efficient Toto, and the owner helped me choose the best model for our needs, likewise I purchased the new Toto through 5 corners and they gave as good a price as you could find anywhere on the web; likewise labor costs were as good as or slightly better than other Seattle plumbers. 5 corners got the new toilet in 1 day and immediately worked with me to schedule an install just a day or two after that. Scheduling window was precise (not +/- 3 hours etc.) and installer showed up exactly on time. Removal of old toilet and installation of new one was smooth and took less than 2 hours. Communication very good throughtout. Overall great process/service and I recommend to others.
