Growing with Harrisburg — Quality Construction for a Booming Community

Harrisburg has exploded in growth over the past decade, and with that growth comes real demand for quality contractors. New homes in subdivisions like Harvest Hills and Dawley Farm need roofing, siding, and windows installed to the highest standards — because these are the homes where young families are putting down roots.

We also serve Harrisburg's growing number of homeowners who are upgrading existing properties — replacing builder-grade roofing and siding with premium materials, adding composite decks, or installing energy-efficient windows to cut utility costs. One contractor, one project, zero coordination headaches.

Harrisburg's proximity to Sioux Falls means homeowners here have high expectations. We meet them — with licensed, insured crews, manufacturer-backed materials, and a commitment to showing up and doing the job right the first time.

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.
