They repaired a backflow valve in Edmonds. Early to appointment. Great work and reasonably priced work. Excellent office and call back support also. I highly recommend Northern Waters for Irrigation and backflow work and testing. read more

We continue to get EXCELLENT customer service from Northern Waters, and at our yearly activation a few days ago, Sam alerted us that we have Japanese Knotweed growing in our yard, an invasive and destructive plant. We've had all kinds of outdoor maintenance people here and he's the first to mention it. Sam is friendly, professional and well-spoken -- and he had our rather complicated system running perfectly soon after he arrived. read more

Still not entirely sure what we paid for. Charged $236 for "evaluated system and identified repairs". System still doesn't work - no evaluation was provided. When we turned on water line ourselves we identified a significant leak near the home - that wasn't addressed by tech. Clearly whoever came out did not even turn on the water line for the area of concern. After questioning what repairs/next steps were they quoted an additional $984 to actually identify the issue with our system. Diagnostic visit was a scam. Do not recommend. read more

They make appointments with us for spring sprinkler activation and winterization so that we don't have to remember to schedule them ourselves. They help with any problems in the line. Very professional. Been using them for 20 years! read more

After 20 years of service, they could not be bothered with our account anymore- saying that they left 20 messages for an old man who was hard of hearing - what they did not realize was that the law firm had RE-routed their phone system. The owners were completely awful having never missed a payment. ... it took 3 weeks to get an entirely new computerized sprinkler system put in by another company- very reasonably. They should be ashamed. Age discrimination, plus terrible service....., for friends of the Nordstrom's. And having worked at Nordstrom's for 15 years so I know better . Nothing more to add Do not call them- they can not be bothered.... read more

I generally have them come in the fall to winterize and backflow check my watering system, then in the spring I start it up myself. This spring I found a leak in a backflow valve. The owner came the next day, fixed the leak, and started up the system, no charge. These guys are keepers. read more

Dave Sheldon has done both major and minor irrigation work for me for over 5 years. In all cases his work was exceptional. He pays attention to the little details that make the difference. I highly recommend him. Superb. read more

Really shocked to find a company that charges for sales calls to install new irrigation systems. All the other irrigation companies I contacted were willing to do a free estimate but not Northern Waters. Beware! read more

After shortlisting few irrigation installation companies in North Seattle area, we went with Northern waters. They provided a free consultation and provided the estimation that was reasonable compared to others. All the workers involved were professional and completed the work timely and did an amazing job at it. We had the sprinklers installed in front and back. They even had a monitor installed to automate all the zones and had rain water detection installed to avoid sprinkler activation during rainy days Overall had a great experience working with the northern watern folks! read more

We recently moved into a new home and discovered the in-ground sprinkler system needed some work - including finding and fixing a leaking valve in one zone. Northern Waters sent out Vince to scope out the work. Vince is a super-nice guy and very competent. He spent an hr diagnosing the issues and then scheduled the repairs for the following week. He worked efficiently and was thorough. I have no problem recommending Northern Waters. My only reason for a 4-star (vs 5-star) review is that they were a bit pricey. It would have been nice to have that initial 1-hr consultation (to determine the problems) applied to our final bill for the actual repairs (like many companies do). read more

Be very careful choosing this company. They are only concerned with THEIR time, THEIR costs. They are NOT interested in customer service.

I couldn't be more pleased with the work. Matt and his partner were total professionals. I was nervous about all the problems we might dig up with our old irrigation system, but Matt made it seem easy. As the owner of a construction business I know how hard it is to keep good people and keep things lined out smoothly, you guys are top notch! And all this, under your original budget. Wow.

Excellent, knowledgeable service from Northern Waters. I've been searching for a sprinkler valve box that was located in my yard 30 years ago and was buried after decades of mulch and plant growth. Paul persevered until he found it. This is a very experienced company. read more

I am on the board of a townhouse HOA with 20 units. We've had trouble in the past with irrigation contractors - shoddy work, unreliable, etc. When trying to find someone skilled and reliable it is difficult as too many contractors won't even return phone calls. Northern Waters is different. They are friendly, reliable, skilled, and they return phone calls. Our installed-on-the-cheap by Sundquist Homes irrigation system is 22 years old and had developed multiple breaks, had jerry-rigged repairs, had many heads which needed to be raised, repaired or moved, and has the usual seasonal system turn on, test, turn off, flush, etc. When I commented to a friend that I was trying to get HOA Board approval to schedule work on a new break, my friend said he has been using Northern Waters for years with good results. His Seattle house is worth over $10,000,000 and has 2+ acres of land with massive irrigation systems (front and back yards). The reason I mention him is to show that they work on projects large and small, all provide quality for all. As an added bonus, talking to them on the phone is always a pleasant experience. read more

I have to write a review just to give some balance to the horrible review left by Sean M. If the reviewer doesn't know what backflow assembly testing is (it's required by certain municipalities like Edmonds), he shouldn't be criticizing the company, nor be rate this business low because they're not plumbers. They are irrigation and lighting specialists. Period. My review: The gentleman who came out to test our system did that, as well as found and corrected incorrect wiring on the rain sensor installed last fall by another contractor, and programmed the system for us. The people you speak to on the phone are also very polite, warm, and professional. We are so happy we found this company. read more

They really don't do plumbing, but I don't know how else to describe it. Once a year I have to get my backflow assembly tested for the water company. I don't know what it is or why its tested, but damn it they want it tested. I think its a big scam, but who am I to argue with the man. So.. I get it tested. I use this company to test it. So, it you need your do hicky tested they should be able to help you. End of story... read more

Vince has been coming for the past couple of years to service our sprinkler system and reprogram our control box after we screwed it up pretty badly! He has added sprinkler heads and drips, re-aimed sprinkler heads and made sure everything was running tip-top. From the call to their office, their really friendly office staff began the quest to get our system adjusted and repaired, then to Vince, who is so fantastic and really listens, never having to repeat requests. We have never had a better company come to our home. read more

I have worked with this company for more than 12 years and find the techs to have an incredible depth of knowledge and experience on landscape irrigation and lighting. They are dependable in taking care of the "spring on" , backflow testing and "fall off" work. They're valuable in helping us to be on top of our irrigation and lighting system maintenance. I work with the team and always get creative ideas on improving the system with great value for the dollar. The company is professional, (very friendly, helpful, efficient admin support) has high integrity and through its actions, I've experienced excellent customer service and satisfaction. In a few mishaps with our lighting and irrigation system over the years, the company has always solved issues with the highest integrity. This has resulted in a highly trusted consultant long term relationship. Recently, our main water pipe into our house had a slow leak flooding our laundry room. My husband and I were continually in and out of town on business trips during the leak. On the same day I emailed Northern Waters, Dave came out to our house, in hours, to track down the source of the leak, and determine a plumber was needed on a time and materials basis. Northern Waters does not do home plumbing. Leak now fixed, but to me, this was an 'over the top" client service experience. read more
