About Us
Built in Sioux Falls. Built to last.
Impact Construction is a South Dakota based construction company built on a simple principle: do the work right, treat people fairly, and stand behind every job. Owned and operated by Tony Lahman, the company brings hands on craftsmanship and straight talk reliability to every project, from residential builds and remodels to commercial construction.
Tony founded Impact Construction with a clear goal: deliver quality work that lives up to its name. Every project carries his personal attention to detail and commitment to building lasting relationships with clients, not just buildings. When you work with Impact Construction, you're working directly with an owner who's invested in getting it right the first time.
Whether you're planning a new build, a renovation, or a commercial project, Impact Construction brings the experience, work ethic, and local know-how to get the job done with integrity from start to finish.
Our Story
Since 2004, Impact Construction has built and remodeled homes across Sioux Falls, Harrisburg, Brandon, and Tea with one goal: create spaces we'd be proud to call our own.
Over 20 years later, that hasn't changed. Our team brings 100+ years of combined experience in new construction, additions, kitchen and bath remodels, basements, garages, and finish carpentry. From ground-up builds to the remodel you've been putting off, you work with the same crew, same standards, and same direct access to the people actually doing the work.
No project is too big or too small for our full attention. We show up with clear communication, honest timelines, and craftsmanship built to withstand South Dakota's weather — and decades of everyday life.
