We’ve been assisting Flagstaff residents since 2003. Over the years, we’ve honed our skills... specifically, plumbing. But here’s a little secret...
We weren’t always this skilled.
In the beginning, we met the low expectations of plumbers. You know the type: show up “whenever”, create a muddy trail, drop a few pipe washers, deliver an invoice and depart.
Yep, that was the “standard”. Unfortunately, it remains the case for many plumbers. Then, a change occurred. Eight years ago, we discovered that plumbing is not merely about plumbing systems... it’s fundamentally about customer service.
This is why we provide easy-to-book appointments, transparent pricing and written warranties. When plumbing issues arise, it can ruin your day. We’re here to help you manage your tasks.
We aim to fix plumbing issues while helping our clients. This is why our service stands out. You’ll see we’re more than just a service; we’re your allies.
Marty entered the world with a wrench in one hand and a hammer in the other. He grew up in Tempe, AZ, on what was once his great-grandfather’s farm. He collaborated with his father and family to build and plumb homes in the area. When he was eight, his teacher requested him to lead a class tour of a house he was assisting in building near the school. Amazingly, he described the plumbing layout and how everything was linked.
During his college years, Marty met Annette, a charming dental assistant from the area and they relocated to Flagstaff. Once Marty finished his studies, he and Annette had developed such a love for Flagstaff that leaving was unthinkable. After gaining experience with various local businesses, Marty secured his Plumbing Contractor’s License in 2003 and launched Mortensen Custom Plumbing.

Rick D.Marty Mortensen, the owner, contacted me and came out to see the what work was done. He sympathized with my complaint and give me gift cards for future work. As I said in my original post, the owner was very responsive and now I can say he also responds to less than stellar reviews on Yelp. Thanks again, Marty.
Alice F.Overall, I had a very good experience with Mortensen. Chad, who worked on my project, was very professional--he showed up on time, was exceptionally courteous, and got the work done quickly. He was upfront about the charges and there was very good communication with the whole team. We have had no other issues with the repair and I also appreciated the follow up afterward to make sure everything was okay. I will concur with other reviewers, however, that this is NOT inexpensive. Yes, this is the most money I've ever spent on a plumbing repair. On the balance, however, it was worth the extra money to me to 1) not have to do it myself, or 2) wait around all day for someone to show up, like I have in the past, and have to supervise every minute of their work. I'm willing to pay more for the piece of mind that the job is getting done right the first time.
I am sad to say we did not have a positive experience with Mortensen Plumbing. Two items really ruined the experience. First, the plumber showed up three hours later than his scheduled appointment. Second, when they provided us a quote to replace our 50gal water heater the price was $3,821. Really, who pays $3,821 to have a water heater installed. I have replaced a lot of water heaters in my day and they do not cost that much. In fact the one they recommended is at Home Depot and we can get the water heater and installation for a total of $1,100.
I was in Phoenix and my wife was taking care of this. It really does feel like they were trying to take advantage of her. Bad decision! She is fully aware of the cost of construction items and their related installation services.
I would not recommend Mortensen plumbing under any circumstance. They should be ashamed of themselves for this sort of practice.
I agree that this team is fast and courteous. However my experience was that the price they quoted was easily 3 times other folks. When I brought this to their attention they simply stated that it was because of their high quality work. I found other very high quality plumbers who accomplished the work at a far more reasonable price. I simply cannot recommend them.
After I posted this not so happy review, they called me to see if we could settle the matter. The gen'l manager came over to look at the sink/drain, and he returned the next week and repaired it properly. He noted the original drain had been installed incorrectly.
I am grateful for the repair, and they didnt' charge me. However, they did not help me until after I made this unhappy customer posting. They were not interested in helping when I phoned and asked to talk about my plumbing problem.
Ah, well. They have a fabulous general manager.
We have always been happy with the fast and courteous service by Mortensen.
They have done repairs and installations in our home and have always done a thorough and professional job. In one case where there was a problem, they followed up quickly and made a corrective repair at no additional charge. Erin is always prompt and friendly with a follow up phone call to be sure that all the work is satisfactory. We purchased a maintenance plan with them and they initiate regular visits to test our plumbing and to flush out the water heaters. Yes, it was a big expense but we believe the quality of their work and their responsiveness is worth it. We would certainly recommend them to others.
Great, fast service--and work done right the first time. Mortenson Plumbing may not be the least expensive but if you believe in that old saying that you get what you pay for, you get good value and exceptional workmanship and professionalism from the folks at Mortenson. We've had them to repairs, install a new water heater, install a new sink, install new toilets and other work and have always been more than happy with their work.
Called Mortensen to fix a rental unit I have in Flagstaff. Kudos to them for calling me back first thing the next morning and getting a plumber out that after noon. My problem was my tenant said he had no hot water which of course I needed to fix ASAP. The plumber got there and diagnosed what was wrong and called me up to see what I wanted to do. The gentleman that did the repair was very knowledgeable and my tenant said he did good work. However I am rating them at a 3 due to I think I was extremely overcharged. To flush the tank and replace the two heating elements cost me $419! If you have the money and are OK with getting overcharged I would recommend Mortensen.
Matt B.The entire team communicates very well! Everyone is bright, clean, cheerful and knowledgable. From the time I recognized I had a problem (gunked up water heater and subsequent blockages all throughout the house) to the time my entire house was back to regular water pressure might have been 3 hours total.
Erin is also very responsive on the Facebook page, either to direct you to resources or to sign you up to have a tech come out.
There is an $89 charge to have a tech come out to your location, but that is applied to any work that gets done, so you're not just paying it extra. That's smart.
I don't own the home I am in, though I am the property manager. They insisted on calling the landlord before stepping foot in the house, which I know he appreciated. The issue was explained to me and then to the landlord, who paid to have everything fixed. It was done *Fast*.
Very highly recommended. They can consider me a loyal customer for any of my properties.
They do terrific work, on-tome, professional, clean, courteous ... everything the homeowner could hope for. But they charge about twice what the next most expensive Flagstaff charges. They have a REALLY slick marketing plan, but, trust me, you pay for it. If you want top quality at top prices, Mortensen is your best Flagstaff choice.
