Business Representative

Nick Mortenson


Hi my name is Nick Mortenson. I was born and raised in Buffalo, MN by wonderful parents John & Bonnie Mortenson. I started my construction company in 1999 after graduating from high school. NMC has been growing ever since and we believe that is due to the high level of customer satisfaction that we strive for with each and every job. In my down time I enjoy hunting, fishing and spending time with my family. I have a wonderful wife Molly, an 11 year old son Jordan and twin 1 - 1/2 year olds Sawyer and Savannah. We love traveling to Florida in the winter months and spend some time with Molly's parents and family. We love our job and are very thankful for the people that trust us with their #1 investments. We plan on having the business continue for generations.

  • I would recommend this business

NMC did an excellent job installing steel siding on our house. We could not be happier with the results. Chris and Tom were extremely helpful in educating us and addressing our concerns. The crew that did the work were very respectful of our home and neighborhood. The final price was almost spot on with the estimate, and the variance was explained in detail before hand so we were not surprised. Very transparent and up front. All in all a very positive experience for us.

Customer Testimonials

NMC Exteriors is a life saver! I’ve had ice dam issues with a little bit of leaking for years, and this year it was the worst it’s been, water leaking all over my kitchen in multiple spots, I have 4 buckets catching water! I was looking for recommendations on a local Facebook bulletin board for a fix & they were referred to me. Jack was so helpful, getting all my info, and said they would send Rick out the next day to look at my issues, this was at 6pm, Rick was here at 1pm the next day! I thought it would be a while to get someone out with so many people having problems this year, but NMC is completely on top of it! Rick was such a knowledgeable guy, very professional and knew right away what my issue was & how to resolve it. This issue has been causing me so much stress, and speaking with Rick just put me at ease! I really wish I would’ve called NMC years ago to fix it! I’m looking forward to working with them and finally having proper insulation & barriers to avoid future problems! No more coming home to puddles on my kitchen floor!!!! Thanks NMC! Great people!

NMC went above and beyond to help get my project done. Nick was always just a phone call away with any questions I had. The crew did an amazing job and my roof is better than it was when my house was built because they took the extra step to make sure it was done right. I would recommend NMC for every job big or small. They are truly first class!

NMC and team was great to work with from start to finish. They replaced our siding and all windows. The sales staff to cleanup crew was professional,, friendly and top notch quality. I highly recommend NMC.

Jack Murphy and the crew over at NMC exteriors do a phenomenal job. From small residential to big commercial projects. Great customer service and always on the cutting edge of technology!

Jack and the team were great at listening to what we needed and being quick about it! Our insurance company recommended them even though it wouldn't be covered, and they did a fantastic job. In at 7am, and out by 2pm with no mess left behind! Would highly recommend.

NMC replaced our roof and siding and did a fantastic job. Installation and cleanup was great. Jeff Sklar and the team at NMC made the whole project easy and seamless. Highly recommend!

NMC Exteriors & Remodeling did an excellent job in replacing my roof that was damaged due to hail storm. All the credit goes to Jack Murphy and his team. They took care of everything, very efficiently and professionally, from working close with my insurance company from day 1 through completion. I highly recommend them.

We had storm damage to the roof of our garage and cabin. Called Nick from NMC and he came up to check it out, he found additional damage and handled the whole insurance process for us. We now have a beautiful hassle-free roof for the cost of our deductible. We also decided to have them replace our windows, doors, siding and soffits. They did an awesome job and we couldn't be more pleased. Thanks for the great job.

NMC did put a new roof on our cabin up north. They did our cabin and two garages and even did our shed for free. They gave us a fair, competitive price and the roof looks fantastic. The area was completely clean when they were finished. I highly recommend NMC, and Jack in particular.

We are very happy with the work that NMC did. Jon Was very helpful in explaining and helping us choose the right materials for our home. We would recommend them to anyone that is in need for home repairs

I'm an Insurance Broker at Novallus Insurance and Jack has helped so many of our clients! He's prompt, friendly, helpful and knowledgeable and makes a sometimes overwhelming situation easier to handle. When my clients have a roof issue (or something else I think he can help with) and don't know what to do, I always send them to Jack and NMC. We treat our clients like family and strive to give them the best service possible and NMC and Jack have always done the same! We're super happy to know you guys!!!
