"George was super helpful over the phone determining the right water heating solution for our home, was highly communicative and transparent throughout the process, and made quick work of the installation of our electric water heater. Would highly recommend to other folks in Seattle in need of a water heater upgrade!"

"Excellent experience with Jacob and Blaine from Seatown. They piped a gas line over to the tankless water heater and installed the heater. They removed the old heater and cleaned up the area. The quality of the work was very high. Both Jacob and Blaine were very personable and polite. We have already booked Seatown to upgrade our electrical panel and replace our old knob and tube wiring and sockets. Highly recommend Seatown."

"They were fantastic. Jared and Jake were very professional and courteous. They went above and beyond when replacing our water heater. The previous owners of the house installed the old water heater poorly. These guys not only replaced the water heater, but fixed all the piping and attachments as well. I’d definitely hire this company again for any plumbing issues."

"Had a big job of 4 water heaters in four different units. Platinum Plumbing blocked off the entire day to get them all done at once. They are friendly, professional, and when it comes to water heaters, very fast. I would highly recommend them to anyone who is looking at having their water heater replaced. I will use them in the future for other plumbing needs should they arise. Thank you!!"

"Previous owner used non-heat rated PVC piping on the water heater. Entire system was almost a decade old so decided to change out the heater at the same time. After giving the owner a good description of the problem he was able to give me a quote over the phone ($1950 + tax). I decided to let them come out and access the job before agreeing. They arrived on time and after a quick assessment the lead plumber quoted me a higher price but after consulting the owner they agreed to do the job for the original price quoted. Mike and John worked quick and efficiently. They were polite & professional and had the entire job complete and work site cleaned in 3-hours. Over all quick and painless process, would use their service again."
