Thank goodness for Montana Insulation Systems. They are a top notch, family owned company. They answered all my questions before, during and after the job. I really appreciated their honesty. They insulated my basement in a timely and professional manner and now I can heat it with a candle. They are completely dependable and I would not hesitate to recommend them to everyone.

We needed an estimate rather quick. Dorn came out the same day when I called and it was later in the day. We new the price right after he took measurements. My husband and I appreciated his communication, value of the project and he showed up when he said he would and took as long as he said he would. We highly recommend Montana Insulation for your insulation needs.

Montana Insulation Systems (MIS) insulated our retirement cabin near Basin, MT. The owner did a great job for us. He bid what it would cost, what he would do and when he would do it. He followed through exactly as he promised. We are extremely happy with the product we received for a very fair price. They did an amazing job of keeping everything clean and organized. We have had trouble with contractors on our project but MIS was a breath of fresh air for us. I highly recommend MIS and would be happy to answer any questions.
