It was a challenge to build a pool that looked like it belongs on our 1875 farm, but Northern Pool & Spa (and all of their recommended contractors) knocked it out of the park!…
Our sales rep, Ryan helped us design a pool and spa that makes our backyard feel like a resort! And Patty (in the office) deserves some kind of award! She handled so much on our behalf and answered so many questions with the utmost patience. We even sent her flowers because she’s been so great! The service team has been so helpful with all the details that could be easily overlooked…I wish all of our experiences with contractors went so smoothly!
Building a pool with this level of finishes was a dream come true and we’re grateful that we picked a great company to work with.

We bought a house this spring that came with a northern pool in ground pool already installed (2 years prior).I am grateful it was northern pool who did the install, bc we referred back to…
them, and they have been SO incredibly helpful and kind, answering all of our newbie pool owner questions- even talking me through the apparatus on the phone at one point! I had them open the pool, as well as give me a maintenance lesson for $150, and it was well worth the money. I learned about each part of the mechanics, was provided an in depth ‘how to’ cheat sheet, and was taught the basics of all the chemicals. Professional and top notch. They know their stuff. We love our pool and although we were hesitant in the work it might require, we are now very confident with northern pool helping us! -thank you! Kate

We installed an in-ground pool with Northern, fall of 2023. From start to finish, every single staff member has been great to interact with, from the guys who dug the hole, to the startup…
…team. I have had lots of “beginner” questions, related to water quality and how to take care of things – the office staff has been patient and attentive, helping me to understand all of the details.
