"My water heater died last week. I went on Home Advisor and received a number of calls. One from George at Stream Water Heaters. We discussed my problem. George requested Photos of the heater and the area around the heater. Within 30mins I received an estimate. The price was totally reasonable for equipment and install. The water heater from a well known company and carried a better than good warranty. I received an install time of 6pm next day. The team remved the old water heater, replaced an obsolete valve, and installed the new water heater. I had numerous questions. All my questions were answered in the most courteous manner. The professionalism, expertise, and timeliness of George's Team were exceptional. Highly recommend this company."

"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."

"The Seatown team did a great job. I got quotes from 3 different recommended plumbing services, but the Seatown guys were the only ones who recognized we would need to upgrade our gas meter. They did a great job explaining how to get this scheduled with PSE. The estimate Seatown gave was on par with some of the other plumbers, so we went with them. They sent 2 service people to come and install the tankless and the guys were just excellent. I expressed concern about mounting the water heater on the beams in our basement because Our house is so old, so they came up with a better solution. They built a small wall frame to mount the water heater. No extra cost. When they found there was no outlet wired near the heater they were able to get an electrician from Seatown to come out and wire one up while they worked on the water heater install. Seatown aldo had a good scheduling method, sent text reminders the day they were coming to do the work with a photo of the person who was coming and a short set of info about the person. It was a nice touch, and a thoughtful safety measure. They did a great job with the install which took several hours. I’d definitely hire them again."

"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!"

"Perfect. I know this because I had a different company come out, say they would install 7-10, after 11th day started getting run around, 20th day I called this company. They came same day, installed within 4 days, submitted my rebate from Duke for me, comes with excellent warranty and they offer a service plan cheap enough I can afford. Single woman who cant tolerate heat along with aging dogs, they put my needs in first. Very happy. Will have them back to install hot water heater! I didn't like that they added $500 to billing to get me the 0% for 5 yrs payment plan but it is what it is in this day."

"Just bought a home and the water heater is failing. Needed to figure out my options between tank and tankless water heaters. Ended up finding out they could not service my house but Matthew still shared his knowledge about my options. This was greatly appreciated as a first time home buyer."

"The need for a footing drain was a surprise to me during my basement remodel due to water leaking in through the blocks. Raman and his team got me on the schedule fairly quickly, did a great job. They also set up new plumbing for 2 bathrooms and a kitchen in the basement, and removed my old water heater and installed a tankless water heater. Any issues that came up, they were very quick to resolve (including an old copper pipe that they didn't install which welding came loose, and they were there same day to fix.) great honest service, reliable service. Pricing, well, plumbing is not cheap, but I think they are comparable to anyone in the business. I would definitely use them again. Thanks Drain Pro!"
