We had several weather delays and schedule conflicts but Mark was very accommodating and moved our installation to a time that worked for us. Brandon, our job foreman, was outstanding – professional, courteous and friendly. The entire replacement took a little longer than anticipated but was due to extremely cold weather. At final inspection there were small flaws noticed on 12 of the double hung bottom slider and Mark immediately ordered replacements at no additional charge to us. I would recommend this company to anyone considering replacement 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.

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.


The young men that worked on both of these jobs were the best people we have ever had work on a job for us. They came early and stayed late. If there was something was something that we did not like they fixed it or explained why it was done that way. They were never impolite or disrespectful. From the owners, job bosses, project bidders, people that answered phones, they were the greatest people we have ever had do a job for us. I would recommend them in a heart beat. We found them at the home improvement show in Billings. In fact The home improvement show will be in Billings this weekend so if you are thinking of new siding or just sprucing up a part of your house that looks a little weary stop by and see them, they are the greatest people you will ever have work on your house.

We wanted to let you know how excited we are to have the house done! It looks awesome and your guys did a great job!!! They were so friendly, courteous and helpful..not to mention a joy to get to know. We were impressed with their ability to show up at 8 am on the dot every morning and work until dark! Impressed that they would check with us to see when we would be awake on the weekend as to not interrupt us..not to mentions that they were always willing to help, answer questions and talk to the kids and others that stopped by to check the place out.

We have had many great compliments already!

Thanks again for a great job!

Over the last 10 years I have regularly used Big Sky Exteriors for my siding, roofing and window needs on both my home and my businesses. The owners and crew are extremely courteous and responsive and the the work is consistently superb. The owners are also very generous donors to local non-profit organizations. I highly recommend Big Sky Exteriors.
