What We Offer

Custom Trims

Our high-quality custom profile trims come in straight and curved casings, jambs, and crowns. We also use various wood species and premium-grade hardwoods and softwoods, depending on your specific needs.

Brackets and Corbels

Our custom wood brackets and corbels are tailored to suit any project. We employ mortise and tenon construction to ensure durability, even for non-load-bearing units. For exterior applications, we begin with No. 1 Cedar and Douglas Fir to minimize checks, splits, and knots.


We create high-quality screen doors using premium vertical grain cedar. We also offer a variety of wood species for custom interior and exterior doors and replicate doors for historical applications. Each project is unique, so contact us for more details.

Stair Parts

We make custom floating treads, starter treads, and other select components. Contact us for more details, or send us a sketch of what you are looking for.
