"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."

"My 20+ yr old water heater failed, sending a stream of water thru my garage. After turning the gas off and draining the tank, I called Seatown based on a referral from Puget Sound Energy and their solid reviews here on Angi. Scheduled the appointment over the phone. Communication was smooth & easy. Received a text 2 hrs before arrival and then 30 minutes out. It included a photo & short bio of the plumber which I thought was a nice touch, both for safety reasons & ‘cause it’s nice to treat people like they’re not anonymous drones. Chris & apprentice Jeffrey arrived promptly. Gave me clear info on options & prices, I approved the bid and they set to work installing a new 50 gal, natural gas powered Bradford White tank storage water heater. I opted for the model with the 10 yr warranty rather than the 6. They were efficient, thorough and personable. Went above & beyond, re-routing a water line and repairing a janky exhaust vent that they thought the city inspector might not like. They even shop vaced the cobwebs from the space before installing the new tank, bless ‘em. Chris explained maintenance requirements, how to read the control panel & use emergency shut offs. Seatown takes care of city permits (my city requires one) which I appreciated. Work was begun around 11 & I had hot water by 3:30. Payment was due upon completion and I got a senior discount. Price was competitive with other companies’. They hauled away the old tank and all packing materials and left a very clean worksite. All in all, a good product, well delivered."

"Rob came out to review our existing system and helped us figure out what kind and brand of heat pump would work best with our system. He was very patient and informative, and answered all our questions without any pressure or up-sells (we had quotes from five providers). We signed the contract and payed our deposit in June 2021, but unfortunately global supply chain issues delayed the parts being received. Day & Nite were communicative of the issue and offered several alternatives, including a refund of the deposit. We opted to wait for the parts. It took four months, but the techs (lead by Jeff B) were fantastic and very accommodating in how we wanted piping and wiring routed. We are very pleased with how it's turned out and loved working with a local (and family owned!) company! Our gas water heater is due for replacement soon, and we'll be coming back to Day & Nite for that!"

"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!"
