Wow!! What a difference. Spencer was neat ( drop clothes) very professional, knowledgeable, and friendly. We are very happy with the work performed and the price line. We will ask for him again. Highly recommend!!!! Ricky D We have loved our experience with the Rocky Mountain team. Mikayla was patient and knowledgeable with our many visits in the showroom. Mike and team were experts in installing our fireplace, and carefully explained all the steps for our desire to DIY the rest. Professional and courteous- they treated us like family. Nothing but good things to say and would definitely do business again with them. Brianna Kjar A family owned and operated business, Rocky Mountain Stove & Fireplace has pride in the finished outcome of their work. From their showroom to the final project wrap up, everyone involved were terrific to work with. RECOMMEND! Cumulonimbus Rocky Mountain Stove & Fireplace was amazing. They were so good this is my first review so that speaks to what fantastic job they did for us from start to finish. Clean, polite, timely, and so detailed oriented. Bruce Stahluth The only place I would go with. Reliable, high quality, and fair pricing. David Johnson Mike and his team are amazing. Their attention to detail is second to none. We are extremely happy with the end result. I would be remiss to not mention Mykayla was so patient and helpful at the showroom. I will definitely recommend Rocky Mountain Stove & Fireplace.
