For two decades, we’ve supported the Flagstaff community. Throughout this time, we’ve perfected our craft... which is plumbing. But I’ll let you in on something...

Our expertise didn’t come overnight.

Initially, we conformed to the typical standards of plumbing. You’re familiar with the routine: arrive “whenever”, leave a mess behind, leave behind some parts, hand you a bill and leave.

Yep, that was the “standard”. Unfortunately, it remains the case for many plumbers. Then, we had an epiphany. About eight years back, we recognized that plumbing is not merely about plumbing systems... it’s fundamentally about customer service.

That’s why we offer flexible scheduling, transparent pricing and guaranteed warranties. If your plumbing acts up, it can add to your stress. We’re here to help you manage your tasks.

We aim to fix plumbing issues while helping our clients. This is what sets us apart. You’ll see we’re more than just a service; we’re your allies.

Marty came into this world equipped with a wrench and a hammer. Raised in Tempe, AZ, on his Great Grandfather’s farm. He worked alongside his father and relatives constructing and plumbing homes locally. At the age of eight, his teacher invited him to show his classmates a home he was working on as a field trip. Surprisingly, he detailed the pipe layout and their connections.

In college, Marty crossed paths with Annette, a beautiful dental assistant from the local community and they relocated to Flagstaff. By the time Marty completed his degree, he and Annette had grown so fond of Flagstaff that they couldn’t imagine leaving. After gaining experience with various local businesses, Marty secured his Plumbing Contractor’s License in 2003 and launched Mortensen Custom Plumbing.

Since the first phone call to the last work day (in 68 mph wind). Mr. M. Mortensen was truly a professional and completed so much work on my 60 year old house. His assessments were spot on, and he completed his work with a pride I have not seen in awhile. I would highly recommend Mr. M. Mortensen not only for his great work ethic; but for his knowledge of plumbing systems and ""can do"" attitude. Mr. M. Mortensen also was patient with my endless questions and was able to guide and suggest things I could do to keep my home safe and running soundling. Long live 60's blue toilets!! And....Mortensen Plumbing. Flagstaff is a word of mouth town, and I plan on making my experience known to all my ""next door neighbors"".
Thank you for such great service!

I've come to depend on Marty for my plumbing repairs and other plumbing needs. He is on time and comes when he says he will. I recently needed a new water heater and could not face another cold shower and he moved his schedule around to accommodate me so I will have hot water for my shower in the morning. He is polite and clean (he cleans up the mess and wears booties over his shoes).

Super service. Marty is patient, thorough and respectful, he answers all my questions and tells me things I need to know that I didn't think to ask. His work is high quality - I don't have loose handles, misaligned fittings, slipping parts like I have had over the years after other plumbing experiences. The first job he did for me was 2 years ago, and all the pieces he fixed continue to work so smoothly. He takes the scary out of plumbing problems. The biggest marker for me, though, is integrity. I sense the highest integrity in Marty - he is a craftsman, not a used-car salesman, and that shines through clearly in his communication style. I most highly recommend him.

I didn't have the best experience with Mortensen Plumbing. We called Marty to video inspect a sewer line on a property we are interested in purchasing. Marty seemed very professional, but would not quote a price over the phone. He said each job is different and he prefers to look at the job before giving a quote. Once his camera was in the sewer line he told me the sewer line was very dirty and there was a lot of build-up that needed to be cleaned before he could run his camera through the line. His quote was almost $1000. I told him I couldn't afford the cost, specifically because I didn't own the property. I had another plumber come out the next day and video inspect the sewer line for $150, and there was not a terrible build-up as Marty had indicated.

We couldn't suggest Mortensen Custom Plumbing enough! Marty was extraordinarily professional. I fancy myself a bit of a DIYer and Marty was patient with my questions and thoughts. Everything about the process of working Mortensen Plumbing was above and beyond good customer service. The receptionist taking the call and making the schedule was friendly and easy to work with. For the two visits required Marty called twenty to thirty minutes prior to the agreed upon time as a much appreciated curtesy. The proposals offered were clear, concise, and offered a spectrum of options for the fix, ranging from a band-aid to a high end custom update, all options clearly laid out price, components, and warranties. On a personal note, as someone who previously worked in the Tech industry, I wholly appreciated his use of technology, he took notes and photographs of our system with his smartphone, and switched over to a tablet for other uses, took payment on the tablet etc. In the future we will use Mortensen Custom Plumbing for all of our Plumbing needs.

Marty, owner of Mortensen Custom Plumbing, talked us into an upgraded water heater for approximately 3,000. The water heater has leaked so severely that it has created mold in the surrounding walls and cabinets. Upon inspection of the heater, Marty proceeded to blame us the home owners and Doney Park Water for the leak. Although he fixed the water heater, he will not take responsibility for the leak or the mold. I agree that he takes advantage of women. I would not recommend Mortensen Plumbing under any circumstance, The plumbing company is ANYTHING but custom!

Great service and response by Marty. The on-line appointment booking was very convenient. Marty was punctual, professional and very flexible with my schedule. He communicated frequently via email and completed the project on time and on budget. Marty replace both our hot water heater and installed a new bathtub, fixtures and tile. The end result is better than we could have expected and we would definitely use Mortensen Plumbing again! Highly recommend.

Marty is as professional as they come. Great service. Even better: we made a new friend.

Our relationship with Mortensen Custom Plumbing began years ago when they diagnosed and fixed a water pressure issue that several other plumbers could not diagnose. Since then we have had them install a tankless water heater, a whole house filtration system, natural gas lines for a gas stove, faucet, sink, garbage disposal, kitchen plumbing, shower plumbing, a 2-way clean out, and low-flow toilets. Their workmanship, professionalism, and response time is outstanding. We have been happy with all work they have performed. We will only ever use and recommend Mortensen.

I have used Mortensen on two different occasions. In both cases there was good contact with their office. Marty called when he was on his way and both times arrived within the appointment window. With both repairs Marty gave me 3 options on how extensive work I wanted done and the cost involved with each. There was no pressure to go with the most expensive one. They are also very good on follow-up to make sure you are happy with the work done. They are my go to plumbers in Flagstaff.
