Keystone Builders in Alcester, SD

Built for the Great Plains — Serving Alcester and Rural Union County

Alcester sits near the confluence of the Big Sioux and Missouri River drainages, in a part of South Dakota where wind, hail, and severe thunderstorms are a regular part of life. Farm homes, rural acreage properties, and in-town residences all need exterior systems that can take a beating and keep performing year after year.

We specialize in durable, low-maintenance exterior solutions for rural properties: metal roofing that outlasts asphalt shingles by decades, LP SmartSide siding that resists moisture and impact, and energy-efficient windows that cut heating costs through long South Dakota winters.

Alcester homeowners deserve honest, reliable service from a contractor who understands rural property needs. Keystone Builders brings that expertise to every job in Union County — no shortcuts, no surprises.

We had an outstanding experience working with Keystone Builders and their owner, Brian, on residing our home. From start to finish, the quality of work and attention to detail were absolutely top notch. During the project, they discovered an issue with rot under the old siding. Brian took the time to walk us through exactly what had caused it, clearly explained our options for repair, and offered great solutions to ensure it wouldn’t happen again. His honesty and expertise gave us total confidence in the process. Communication was excellent throughout the entire job—Brian and his team were always responsive, informative, and respectful of our time. Their professionalism and the cleanliness of the jobsite really stood out. And to top it all off, the project was completed right on schedule. We couldn’t be happier with the results and highly recommend Keystone Builders to anyone looking for reliable, high-quality workmanship. Thank you, Brian and team, for making this such a smooth and positive experience!

Brian was prompt and always here when he said he would be. His skills are outstanding. He replaced siding, fascia board, window trim, an odd shaped window, a patio door and front door with precision. I would definitely recommend him for more projects.

Sheryl Frey Google review · June 2025

Brian with Keystone Builders is very friendly and a skilled professional. Brian removed our old shingle roof and replaced it with a quality metal roof. Once Brian started our roofing project he watched the weather and worked very hard to get our new roof installed in a very timely manner. If I could, I would give a six star rating! Thank you Brian with Keystone Builders!

Scott Montgomery Google review · November 2025

Brian with Keystone Builders is a very hardworking and capable craftsman. He has attention to detail and is very fair minded. He is also extremely dependable. I would highly recommend him for your next project. He was my main guy to frame my 8,500 square foot custom home with 12/12 pitch roof. This build was complex and he stayed on the project throughout treacherous weather and other very challenging aspects of this multi year project.
