Get matched with top tankless water heater repair pros in Mountlake Terrace, WA

"They came out quickly to give me a estimate for replacing my 10 year old Rinnai heater. They actually told me NOT to get the additional optional recirculating feature that another company was recommending, due to cost and reliability issues. When Washington Water Heater’s bid came in it was about 40% less than the other guy for the same work and same water heater (minus the recirculating feature)- $5200 vs $9100. They didn’t require any money up front (other guy wanted 50%) and were able to schedule the work for only a few days out (other guy said it could be weeks or months). The showed up on time, did excellent work and even charged me slightly LESS than the original bid because they ended up not needing to install a pump for the condenser."

"Great. I received 3 bids and Drain Pro's was the most competitive and thorough. We scheduled a date, and installation was done in a day. They removed my old electric water heater and were tidy and very professional. I paid by check as they left. Now I will have to install an electrical outlet next to the heater but meanwhile, it's on an extension cord... Looking forward to 24-hour hot water, and a lower electric bill!"

"Discovered my water heater was leaking like a sieve about 8pm on a Wednesday, called a few places none could guarantee next day. Then I contacted Knockout, were able to accommodate the next morning and price was as good or better than the others. A half hour later a tech called to walk me through turning off and draining the broken water heater. Next morning at 9:30am the Knockout guy arrived and by noon I was taking the best shower of my life. Water heater is performing great, seems like top quality as was the service. Highly recommend!"
