They did an awesome job!!! We searched locally for seamless siding and could not find anyone who had what we wanted. Then we came into contact with Big Sky Exteriors out of Montana at a Home Show in Gillette, Wy. and they had exact type of siding that we wanted PLUS stone for the front of the house!! AND they were approximately $20,000.00 cheaper!!

First, Rob spent a lot of time with me going over the options, giving the pros and cons of each siding material, considering the climate/weather. Very knowledgeable, took time to answer all my questions and concerns.

Big Sky Exteriors tore down the original siding, put up a barrier and put on insulation prior to putting on the metal siding. All windows and doors were wrapped/trimmed out with new metal material, soffits and fascia were replaced. They helped with finding a solution to an old covered patio as well.

They hid cables behind the siding, therefore no cables are visible, making the outside appearance look great.

The project went very well. I was kept informed of the timeline at all times. From ordering of the material, to the date it arrived and when the project would begin. The team that worked on site were friendly, courteous and kept me informed regarding the scope of work they were performing each day. They verified the wants and needs I had relayed to Rob regarding what cables to hidden under the siding, vents to be replaced, verified the corner wrap colors, etc… They cleaned up the job site each evening and made sure the area was tidy when the project was done. Even in April, when the weather can be cold and miserable, they were out working diligently.

I think that the communication between myself, the crew and the business owner was great. Everyone was helpful during the whole process. The home looks fantastic. Friends, family and even the previous owner of the home were impressed by how great it looks and the workmanship.

I would definitely recommend Big Sky Exterior Designs to anyone who is in the market for new siding. My home looks fantastic and I find myself staring at my home, impressed by how great it is now!

I couldn’t be more happy with the level of customer service. Rob and his team are top notch. If you want something done with fair and honest pricing look no further. From my windows to my roof and siding they have done it all and I keep coming back. Give them a call, you won’t be sorry.


We have used Big Sky Exterior Designs for a number of projects and are extremely pleased with their products and work.


We first used Big Sky ED’s services in 2007 when they replaced windows and siding on our house giving it a whole new, fresh look. We were impressed by the knowledge, friendliness and professional work done by them and their crew. Two years ago, after storm damage, siding needed to be replaced on 2 sides of the house and raingutters were ruined. Our insurance company was using an out of state adjustor that was absolutely impossible to work with. After months of jumping through hoops trying to come to terms so the work could be completed, Rob M. met with us and our local insurance agents. He had pictures of the damage and siding samples as well as pricing information from his suppliers. Thankfully, he was able to get things squared away and our repairs were done. Big Sky ED has since done jobs for numerous neighbors and relatives to their satisfaction. I will continue to recommend their services and will surely use them in the future for any construction needs.


We had new windows installed by Big Sky this summer – I can’t even begin to tell you how extremely impressed I was with the entire organization! From Curt who sold them to me and explained every little thing to me with the utmost of patience, to the awesome installers and even with issues in the arrival of the correct windows and the funky things that happened in my house when they took out the old windows they all were great to work with!!!

Last spring Big Sky Exterior Designs replaced 14 windows in our 1980’s house with Simonton 5500 series windows. Our old windows leaked badly, and, in some areas, had rotted out the sill & supporting studs. Mark and his crew rebuilt those areas and installed the new windows plus put maintenance free trim on the outside. On the inside, new wood moldings were installed. The workmanship was excellent. When winter arrived, we found the house seemed much warmer and our power bill was less even though this winter was colder than last.

One of the double-hung windows cracked for unknown reasons. Rob of Big Sky Exterior Designs immediately ordered a new window free of charge, and we replaced it before the end of the year. We couldn’t be happier with our new windows.

We attended the Home & Garden Show in Billings, and we were impressed with the presentation made by one of the owners (Rob) from “Big Sky Exterior Designs” on windows for our house. With utility bills going up, we decided to go for new Simonton windows. We were told it would take two weeks to have windows made, and they were booked until September until they could install them. But with circumstances of their work schedule, they installed the windows earlier to our surprise (end of June).

Fourteen windows and a bow window were installed in 3 days. (the bow window replaced a picture window). We were impressed with the way they were installed-well insulated, finished inside & out. This was a very professional job! Thank You.

We were also impressed that the other brother (Mark) who is also part owner of the company, was the one who installed the bow window. This tells us that they care about their work. We are very pleased with our new windows.

Big Sky came out and put siding on one of our houses. Did a great job and cleaned up before leaving every night. The job crew was very efficient and seemed to take pride in the work they were doing.

Big Sky Exterior Designs is an excellent company for siding and windows. Everyone is professional and helpful and want to make sure the customer is satisfied. The workers made sure the work space was cleaned up each day. They helped with design ideas at the beginning of the process and did not try to sell me anything I didn’t need. They use very high quality products with excellent warranties. I highly recommend them to anyone wanting a pleasant experience when getting windows or siding installed.
