On the edge of Puget Sound, the city of Mukilteo has an interesting and important history. Although people often disagree about the meaning of the name, it may refer to the narrow sand spit that served as the original Mukilteo landing on Puget Sound. Historically, Mukilteo was a notable trading post and fishing village. In modern times, it is one of the more affluent suburbs of Seattle, with an important role in the metropolitan area’s manufacturing corporations.

Very pleased with the professional technician, Donavan, who came out when our water heater quit working. This was the third major problem with this water heater, so we took his advice and replaced it. Thankfully, he was able to also install the new one right away. I had confidence in his advice and ability to do the job. He was thorough and friendly. It was a five star experience. I highly recommend.

S. Lippold

Outstanding Service! Scheduler was pleasant and receptive. Technician (Collin) communicated well, arrived in the agreed upon time frame, diagnosed the problem and fixed the issue quickly. Previously, we had two other companies misdiagnose the problem and one company stand us up for a scheduled appointment. If we have plumbing issues in the future, Day & Night Plumbing will be our first call !

M. Lindell

Collin was our tech and he was very knowledgeable answered our questions and what they charged was very reasonable and we are very happy to have water again. I was really impressed by everyone that we dealt with they all were professional and helpful.

We had a great experience with Day and Nite from start to finish. Chris was great at the no obligation consult. He explained things clearly and covered everything but didn’t waste our time. They also provided lots of options and thoroughly explained them but never tried to push or up-sell us. Installation was fast and very professional. We will definitely be using Day and Nite in the future.

I had the privilege to meet Zach on two separate occasions within a two week span. He was upfront and honest about the work that needed to be done. He is a hard-working, dedicated, professional employee of Day and Nite Plumbing. He explained what needed to be done. I asked questions and he was patient and explained things further so that I truly understood.

D. Lee

The technician was great: he knew exactly what the problem was and fixed it quickly and efficiently. Even when a glitch happened in the repair, he was totally prepared to handle the situation. I will definitely contact Day & Nite Plumbing for future problems. Thank you!
