Stair Parts & Custom Stair Components

From treads and risers to handrails, balusters, and newel posts, our stair parts are milled to specification using carefully selected hardwoods and proven production methods.
Stair Parts Custom Made in Mill 3
Balusters and Balustrade
Balusters are the vertical posts supporting the railing, working with the handrail to form the balustrade system. While three balusters per foot is standard, tighter spacing can add an elegant touch to your design.
Handrails
Handrails provide support and safety, resting horizontally or at an angle above the balusters. Smooth transitions in handrails are achieved using fittings like volutes, turnouts, or goosenecks, blending practicality with style.
Newel Posts
Newel posts are the larger vertical supports anchoring the balustrade system. Placed at key points—like the base, top, and turns of a staircase—they provide both structural support and a bold design element.
Treads and Risers
Treads are the horizontal steps you walk on, while risers are the vertical supports beneath them. For a sleek, modern look, risers can be omitted, creating an open tread design.
Nosing
The nosing is the edge of the tread or landing tread that extends beyond the riser, offering more walking surface and a polished appearance.
Fittings and Moldings
Fittings such as upeasings and goosenecks create smooth transitions when the handrail changes height or direction. Decorative moldings, like cove molding, enhance the design by covering joints between treads and risers.

DeckWise® Deck Cleaner Parts 1/A & 2/B
Wood traps dirt, pollen and grime and when using exotic hardwood lumber it pays to maintain it. The Part 1 cleaner eliminates mildew, dirt, mold and stubborn stains. It also removes graying and reconditions Ipe, Tigerwood, Cumaru, Redwood, Cedar decking and outdoor wooden furniture or hardwood siding. Rejuvenate the rich color and distinct wood grain patterns and restore the all-natural lavish color before properly refinishing. The concentrated powders are developed to clean external hardwood decks, fences, hardwood siding, wood railings, benches, chairs and other outside wooden objects.
The Cleaner Part 1 is an oxygen rich wood cleaner that contains no bleach. When you follow the instructions on the Deck and Wood Cleaner label, the product is safe to use and will not damage wood, vegetation or lawn and is bio-degradable. Do not use a power washer on hardwood lumber which could leave scars and raise the wood grain. Always scrub with a non-metal brush. Wood cleansers can easily increase the pH level of lumber. Always follow cleaning with the DeckWise® Deck and Wood Brightener Part 2.
DeckWise® Deck Cleaner & Brightener Part 2 restores the pH level back a neutral state. It also removes tough rust and tannin stains caused by leaves, as well as mold and fungi stains while brightening the hardwood for finishing. It is recommended for use on most species of hardwood, including Redwood, Ipe, Cedar, Cumaru, Tigerwood and thermally modified softwoods. Brighten and restore the all-natural allure of outdoor wooden decking and rainscreen wood siding, outdoor furniture, hardwood fences, wood railings and steps. The goal of our product is to prepare the wood after cleaning and to eliminate the caustic affect from the Cleaner. The Brightener Part 2 is an oxygen-rich formula that contains the ingredient Oxalic Acid. It is a pH neutralizer and will re-establish the pH level to the wood.
Once the wood pH is neutral, the wood is ready to accept your choice of stain or oil finish more evenly and will certainly improve the beauty of the wood. We recommend our Ipe Oil Hardwood Oil Finish. The brightener also prepares new wood by stripping mill glaze. It can be used to eliminate rusty areas on concrete, brick and masonry as well. The Brightener Part 2 is a powder concentrate offered in 16 oz. jars. Mix at a 4:1 ratio with warm water. For tougher jobs, you may require several applications or a more powerful mixture.
