What customers say
Real reviews from homeowners across eastern Idaho.
★★★★★“We hired Montana and the fellas at Big Sky Builders to build a Trex deck and cover/roof. The workmanship is top notch. Montana is very easy to work with and when design changes came up, he worked with us to build what we wanted. They helped us achieve the deck of our dreams.”
John B.Trex deck and cover · April 2026
★★★★★“The mix of rock and siding completely updated the exterior, and the redesigned entry is both beautiful and safe. They also did a fantastic job refurbishing our back porch. Communication was excellent, the price was very reasonable, the craftsmanship and dedication truly stood out. They turned our house into a home we’re proud to own.”
Cynthia B.Siding, stone and entry · February 2026
★★★★★“Excellent work, professional standards. Complete reroof of home and siding, made the home look new again. We have had lots of neighbors comment on the job and how much it changed the curb appeal. We absolutely love it.”
Juanita G.Reroof and siding · June 2025
★★★★★“The deck came out better than we could have hoped for. The crew was so polite and did what they needed for us to get in and out during all of this. We are disabled and they made special steps so we can comfortably walk up and down. They cleaned everything up so nice.”
Kyra G.Deck · February 2026
★★★★★“Montana and crew did a fantastic job with installing the siding on my home. They were efficient, professional and showed up when they said they would, even working in cold, windy conditions. I highly recommend Big Sky Builders.”
Frank G.Siding · April 2026
★★★★★“I was replacing an old wobbly 10x20 deck and stairs. I got a quote from Big Sky Builders and two others. The new deck looks absolutely fantastic. The quote was reasonable and the materials were all as agreed. I would definitely use them again.”
Nathan K.Deck and stairs · May 2026
★★★★★“Impeccable work ethic, polite and very quick to do the work. The whole crew went above and beyond several times helping to move things around the house. They even went so far as to help mow the yard while our mower was in the shop!”
Jaime W.Deck · May 2026
★★★★★“Montana, with Big Sky Builders and his crew were all over my little project. We first talked on Friday, and on Monday it was knocked out. From GO he had my back. Honest, Quality and a real PRO at every turn!”
Todd F.Home project · June 2026
★★★★★“We had Big Sky Builders put siding on our home, along with new front steps and back deck. Montana was very helpful to us selecting the materials. We made a few changes and they were very accommodating. The cost stayed within our budget. Communication was very easy.”
