Custom Carpentry Services in Spearfish, SD by Master Craftsmen
At CNT Builders, we believe the little details make the biggest difference. Whether you’re remodeling one room or building a brand new home, our custom carpentry work brings warmth, character, and master craftsmanship into your space. This is made possible as part of our custom cabinetry services that make your home remodel or build unique. From beams and doors to built-ins and ceilings, we design and build wood features that are made to fit your home—and your style—perfectly.
We proudly serve Spearfish, Sturgis, Rapid City, Lead, Deadwood, Belle Fourche, and surrounding areas. Here’s what we can build for you:


Custom Beam Work
Exposed ceiling beams add a bold, beautiful touch to any room. They can give your home that rustic, farmhouse feel—or something more modern, depending on the wood and style you choose. We build and install both real and decorative beams that look great and hold up for years to come.
What to Expect:
We help you pick the right look, measure your space, build the beams, and install them securely. Whether you’re updating an old space or starting from scratch, we’ll make sure they fit just right.
Custom Doors
Why settle for a door that looks like everyone else’s? We build custom interior and exterior doors that match your home’s style and size. You can choose the wood, design, and finish that works best for you—whether it’s a bold front door or a quiet pocket door inside.
What to Expect:
We measure everything carefully, help you pick your design, build or source the door, and install it with solid craftsmanship.
Custom Built-Ins
Built-in shelves, entertainment centers, benches, and storage units make your home more functional and look more polished. We design them to fit your space exactly, so they feel like they’ve always been there.
What to Expect:
We’ll talk about how you want to use the space, design a custom piece to fit, and install it with clean lines and quality materials.

Split Jambs
Split jambs are used around doors to help everything line up nicely—especially in homes where walls aren’t perfectly straight or even. They give the doorframe a clean, finished look and help with easier installation.
What to Expect:
We build these to match your trim and door style, then install them so your doors open and close like they should.
Coffered & Trey Ceilings
Looking to make your ceilings more interesting? Coffered ceilings add a grid of beams for a high-end, traditional feel, while trey ceilings create depth and layered lighting options. These designs can really make a room feel custom and elegant.
What to Expect:
We work with you on a design, frame it in, and finish it with your choice of paint or stain. Lighting options can be added too.


Custom Millwork
Millwork is the finishing touch that ties a room together—things like baseboards, crown molding, window and door trim, and decorative woodwork. We can match what you already have or create something totally new.
What to Expect:
We measure, build, and install everything so it lines up cleanly and looks like it belongs.
