Get matched with top tankless water heater installers in Issaquah, WA

"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!"

"My water heater tank stopped working so I decided to convert to a tankless system. Chad and George were who I worked with. I had a great experience with both of them. I was very pleased with their knowledge, work, communication and help. I would highly recommend them to other house owners."

"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!"

"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."

"They came out the next day and was able to install a new water heater for me. They even matched the other bid I had received. Very friendly and professional installers."

"Dominick was on time explained what he was going to repair did a great job explained and wrote up estimate for replacing a new water heater fast service, polite technician explained my options for new water heater to be replaced in Jan great guy will hire him in Jan to replace the hot water heater"

"We called at 8 am and had a technician here by noon. A new water heater was installed by 2:30. Milton was compassionate (we were frazzled) and knew exactly what to do. Really grateful for the care and expertise."

"Install was on time and as described. '1st Response' did the job I expected for the water heater install. Good customer service for scheduling. Note that the Angie's list price of $799 only covers the installation of 50 gallon gas AO Smith hot water tank. Assuming you also do installation of new brass fittings, new flex lines and new expansion tank (which you should probably all do with the new water heater) it will cost an ADDITIONAL approx $500-600 (mostly labor costs). That's a competitive price but still, you should be aware that the original quote is just for the water tank install itself, nothing else. All-in-all they did a good job for a competitive price. A few months after the install, so far, I can say I would recommend them for this type of work."
