Custom Interior Finish Carpentry in Hill City & Rapid City, SD

When the framing is done, the paint is dry, and the major installations are in place — that’s when finish carpentry begins. And it’s where the difference between a good home and a great home becomes clear.

Precision Trim and Detail Work That Sets the Standard

Finish carpentry is the final visual layer of your home’s interior. When done well, it creates crisp transitions, symmetry, and visual appeal that elevates the look and feel of every room.

We specialize in:



  • Crown Molding & Ceiling Trim – Add height and elegance to any space
  • Baseboards & Shoe Molding – Create a clean line between floors and walls
  • Door & Window Casings – Frame out features for a finished, custom look
  • Chair Rails & Wainscoting – Add visual interest and durability to walls
  • Coffered Ceilings & Beams – Architectural features that draw the eye
  • Wall Paneling & Built-In Shelves – Functional design elements with timeless appeal

We install all trim and millwork with tight joints, balanced spacing, and smooth finishes that reflect a higher standard of craftsmanship.

Built by a Carpenter Who Cares About the Details

Our approach is simple: measure twice, cut once — and never leave a job without getting it right. Brandon Faehnrich brings decades of hands-on finish carpentry experience to every project, whether it’s a single room of baseboard installation or a full interior trim package on a custom home.

Clients appreciate that we:



  • Take the time to get every line straight and every joint flush
  • Use quality materials that stand up over time
  • Collaborate with builders, designers, and homeowners seamlessly
  • Respect your home and clean up thoroughly at the end of each workday

We don’t just bring skill — we bring pride in the work.
