I have used Mountain Man to have my chimney inspected and to do some work to make sure the connector on my wood stove met specifications. Two different crews have come out and I have talked directly to Jake (the owner). Great experience working with Mountain Man. Everyone associated with the business, from the office staff to the technicians are so professional and kind. Great to have such a high quality business in the area.

Thank you for the kind words and for trusting Mountain Man with your chimney and wood stove! We’re so glad you had a great experience with our team. We truly appreciate your support and are proud to serve our local community!
My home developer-installed gas fireplace unit had the wiring all messed up and it melted. Nick did a fantastic job working around the issue of the useless physical switch by installing remote control, cleaning the unit, doing touch-up painting for some chipped spots, and carefully arranging the interior to greatly improve the flame. Very thorough and professional work. Highly-recommended!

Hi Janet,<br><br>thank you so much for your 5-star review! We are very proud of our team and the expertise, knowledge, passion, and care we bring to each customer.
I just got off the phone with Jamie, she helped me to set up my first appointment with you guys and I would just like to say, WOW! I am very impressed with her knowledge and professionalism! I was out of your service area (Westminster) but Jamie was able to help me out and for a little extra they will be coming out to do a much needed service on my pellet stove. Jamie was so good at her job that I am not going to waste any time calling other companies, I got scheduled right away. If the service technician is as good of an employee as Jamie is then the owner needs to teach a class on how to hire such amazing staff! The owner better hold onto Jamie, because if not, she has an offer to work for the company I work for lol! Great job Jamie! And thank you!

Hi Derek,<br><br>Jamie is truly a rockstar - we don't know what we'd do without her! She, as well as the rest of our admin and sales teams and of course our technicians, go above and beyond because it's YOU, our amazing customers, who are the driving force behind what we do!
Just had Chris and Dom out to sweep and clean two chimneys at our house. They arrived on time and were courteous and professional throughout their visit. They explained everything thoroughly and welcomed any and all questions I had about the process. They made sure none of the dust escaped, and the area around both fireplaces is cleaner than before they arrived. Highly recommend them and appreciate the knowledge that we can continue to use our fireplaces with no worries.

Hi Tanya, thank you for your kind review and thank you for trusting us with your home! Our crews are the best - they're true professionals. We look forward to serving you again with all of your fireplace needs!
Mountain Man Fireplace & Chimney misinstalled a chimney liner and electric fan on my wood burning fireplace in Denver. Instead of installing a separate conduit for the electrical wire to the fan, they ran the electrical wire right on the outside of the liner, between the brick and the steel. The electrical line then melted and the fan stopped working. When MM came to inspect the problem, they pointed to hazy explanations for why the fan wasn't working, all the while never admitting the obvious installation error. It was only once I had another company do an inspection that I understood why the fan wasn't working. Mountain Man also poorly installed two Valor gas fireplaces in my house, neither of which work very well. If you live in Denver I recommend CrownUp Pros instead.

Dear Connor, thank you for voicing your concerns about our installation. On 12/1/25, you called our office to say that when we worked on the blower, we left an electrical wire inside the liner. Please note, we did not install the liner so there is no way for us to have “left” a wire inside the liner. On 12/22/25, you sent pictures from the other company’s inspection report, which revealed that the wiring was actually done correctly. Our estimation is that you were convinced to pay $12,500 for a new Enervex based on faulty information. On 12/23/25, you confirmed that the wire was not IN the liner as you previously stated. We are therefore confused as to why you would leave us a one-star review for something we did not do.
Very professional and spent time to educate me on fireplace maintenance. Would recommend 11/10

Hi Robert, thank you so much for your review! Educating our customers about their fireplaces, stoves, and inserts is an important part of what we do. We're happy to have helped you get the most from your fireplace. Best wishes for the new year!
Cliff was amazing! I made the decision to stop cleaning my chimney myself this year, and it was the best decision I've made. Cliff and team gave me more than just a cleaning, but a full consultation, and left every part of my stove in better condition than when they got here. I'll use Cliff and team again forever.

Thank you so much for your kind review, Brandon! Giving up DIY chimney cleaning to the pros is a great decision on so many levels. We're glad you chose us, and look forward to serving you for many years to come!
Bryan, thanks for the 5-Star Google Review! We love our Certified Technician Cliff, he is knowledgeable and professional, and we're so glad you think so too! Stay warm, -MMFCI
Highly recommend! Mike and Dominik were our service guys and they were awesome. Dominik did a diagnostic and cleaned our gas fireplace that hadn't been serviced in over 10 years. He did an amazing job. I couldn't even believe how clean and beautiful it was when he was finished. Thank you, thank you. Will definitely use again!
