Trim

The Detail That Defines the Room. Hardwood Trim from AB Hardwoods.

Trim is the punctuation of a well-built interior. It's the line between the wall and the floor, the frame around the door, the cap on the window, the crown that ties the ceiling to the room. Done right, it's invisible in the best possible way — it simply makes everything feel finished, intentional, and complete. Done wrong, or done with inferior material, it's the first thing people notice for all the wrong reasons. At AB Hardwoods, we supply solid American hardwood trim for the builders, woodworkers, designers, and makers who understand that the details are where the craft lives. Real wood. Real character. Milled to perform.

Finish your project with hardwood trim that adds detail, character, and craftsmanship to every room. Contractors, homebuilders, woodworkers, interior designers, DIYers, and artisans can count on American Born Hardwoods for trim that complements floors, stairs, cabinetry, walls, and custom interiors.

Who We Serve

Contractors & Homebuilders

Finish trim is the last thing that goes in and the first thing the client sees. Builders who specify solid hardwood trim are delivering a product that holds paint and stain better, nails and glues more reliably, and holds up to the wear of daily life in ways that MDF and finger-jointed pine simply cannot. Our trim stock is kiln-dried, straight, and consistent — the qualities that keep your finish carpenters moving efficiently and your clients satisfied at walkthrough. We stock the profiles and species that production builders and custom builders alike depend on, and we can supply the volume your projects require.

Woodworkers & Finish Carpenters

For the craftsman doing custom millwork, trim is an opportunity to show what's possible with real material. Running your own profiles, matching existing historic millwork, creating built-ins that flow seamlessly from floor to ceiling — all of it starts with quality stock. Our hardwood trim blanks give you the clean, stable material you need to run consistent profiles without tearout, chatter, or surprise defects. Whether you're working with a shaper, a router table, or a full moulder setup, the quality of your starting material determines the quality of your finished profile.

Interior Designers

Trim is a design element, not just a construction detail. The species you specify, the profile you choose, the finish you call out — these decisions shape how a room feels at a fundamental level. Thick, bold casing in walnut makes a statement. Delicate, painted maple trim in a historic home disappears into the architecture the way it should. White oak base and casing in a contemporary interior ties the floor to the walls with quiet authority. We work with designers who need species consistency across an entire project and can help you source trim that integrates seamlessly with your flooring, cabinetry, and millwork specifications.

Do-It-Yourselfers

Upgrading the trim in your home is one of the most transformative improvements you can make — and one of the most accessible for a motivated DIYer. Replacing hollow builder-grade casing with solid hardwood, adding base cap or crown to a room that has none, or installing picture rail in a historic home are all projects that deliver outsized visual impact for the effort involved. AB Hardwoods gives you access to the same quality material the professionals use, in the species and profiles that match your project. If you're not sure where to start, we're here to help.

Artisans & Custom Millwork Shops

Bespoke trim work — hand-carved moldings, historically accurate reproductions, custom profiles for restoration projects — demands material that's up to the task. Artisans and millwork shops working on high-end or historic projects need access to clear, straight-grained stock in species that match the original work. We source with the custom market in mind and carry the species, grades, and dimensions that make exceptional millwork possible. When the profile matters and the material has to be right, AB Hardwoods is the call to make.

Hardwood Trim Species

Walnut Trim

Walnut trim is the mark of a truly high-end interior. Its rich chocolate-brown color, straight grain, and natural luster make it the species of choice for casing, base, and built-in millwork in luxury residential and commercial applications. Walnut machines beautifully — it runs clean profiles without tearout, holds crisp detail, and finishes to a depth and warmth that no stain on a lesser species can replicate. In a room with walnut floors or cabinetry, matching walnut trim creates a cohesion that feels effortless and intentional. Even as an accent — a walnut window stool against painted walls, or walnut base against white oak floors — it commands attention without demanding it.

White Oak Trim

White oak has become the defining trim species of contemporary American design, and it earns that status every time. Its warm golden-tan color, tight grain, and exceptional stability make it ideal for base, casing, crown, and built-in millwork in modern and transitional interiors. White oak's natural hardness (1360 Janka) means it holds a profile edge cleanly and resists denting in high-traffic areas like door casings and base. Its tight pore structure takes clear finishes beautifully and responds well to wire brushing and light fuming for a more textured, contemporary look. For designers specifying white oak floors and cabinetry, white oak trim is the natural and cohesive choice.

Red Oak Trim

Red oak is the most widely used hardwood trim species in North America — a position it holds because it delivers consistent performance at an accessible price point. Its bold, open grain and warm reddish-brown tones accept stain readily and evenly, making it the go-to choice for matching existing red oak floors and millwork in traditional and transitional homes. Red oak machines well, holds a nail cleanly, and sands to a smooth finish that takes both paint and stain with equal reliability. For builders and homeowners working in classic American interior styles, red oak trim is the dependable, proven choice that has defined American homes for generations.

Hard Maple Trim

Hard maple trim is the benchmark for painted millwork. Its fine, uniform grain and creamy white color provide the smoothest possible substrate for high-gloss and semi-gloss paint finishes — the kind of crisp, clean trim work that makes a room look like it was built by someone who cared. Maple's exceptional hardness (1450 Janka) means it holds profile edges sharply and resists the dings and dents that softer species accumulate over time. For contemporary interiors where trim is painted white or off-white, hard maple delivers a surface quality that MDF cannot match and that finger-jointed pine doesn't come close to. It's also an excellent choice for natural-finish trim in modern and Scandinavian-influenced interiors where a light, clean wood tone is the goal.

Common Trim Profiles & Sizes

Hardwood trim is available in a range of standard profiles and dimensions. Understanding the options helps you specify the right material for your project and avoid substitutions that compromise the finished look.

• Base molding — Typically 3½" to 5½" tall, ¾" thick. The most visible trim element in any room, running along the floor-wall junction. Available in colonial, craftsman, contemporary, and custom profiles.
• Door & window casing — Typically 2¼" to 3½" wide, ¾" thick. Frames door and window openings and is one of the first details clients and buyers notice in a finished interior.
• Crown molding — Typically 3" to 6" face width, installed at the ceiling-wall junction. Available in simple ogee profiles through complex built-up assemblies for formal interiors.
• Chair rail — Typically 1½" to 2½" wide, installed 32"–36" above the floor. Protects walls and adds horizontal visual interest in dining rooms, hallways, and formal spaces.
• Picture rail & panel molding — Smaller profiles used to create wainscoting, board-and-batten, and decorative panel systems. Available in a range of widths and thicknesses to suit historic and contemporary applications.
• Flat stock & trim blanks — Clear, straight-grained hardwood in standard thicknesses (¾", 1", 1¼") and widths (2" to 12"+) for custom profile work, built-ins, and millwork shops running their own moldings.

The Feel of Solid Hardwood Trim

Pick up a length of solid hardwood trim and you feel the difference immediately. The weight of it. The way it doesn't flex when you hold it at the end. The clean, smooth face that's ready for finish without the skim-coating and sanding that MDF demands. Run your finger along the profile edge and feel how crisp it is — how the detail holds without crumbling or telegraphing the substrate beneath. That's what real wood does. It holds its shape, takes its finish, and improves with age in a way that no composite material can replicate. Solid hardwood trim doesn't swell and crack at the base when the floor gets wet. It doesn't telegraph fastener heads through the paint six months after installation. It doesn't need to be replaced when you refinish the floors. It's there for the life of the house, doing its job quietly and beautifully, the way good trim always has.

Frequently Asked Questions

What is the best wood for interior trim?

The best wood for interior trim depends on the finish and the application. For painted trim, hard maple and poplar are top choices because of their fine grain and smooth surface. For stained or natural-finish trim, red oak is the most widely used and cost-effective option, while white oak is the leading choice for contemporary interiors. Walnut is the premium choice for high-end natural-finish millwork. All of these species outperform MDF and finger-jointed pine in durability, nail-holding, and long-term stability.

What is the difference between base molding and casing?

Base molding (or baseboard) runs along the bottom of the wall where it meets the floor, covering the gap between the flooring and the drywall. Casing is the trim that frames door and window openings, covering the gap between the jamb and the wall surface. Both are typically the same species and profile in a well-designed interior, but they are different components with different installation methods and dimensions.

Can hardwood trim be painted?

Yes — hardwood trim takes paint exceptionally well, often better than MDF or finger-jointed pine. Hard maple is the top choice for painted trim because its fine, closed grain provides the smoothest possible paint surface. Red oak and white oak can also be painted, though their open grain may require a grain filler for the smoothest results. Walnut is rarely painted — its natural color and figure are too valuable to cover.

How do I match new trim to existing hardwood trim in my home?

Matching existing trim requires identifying the species, profile, and finish of the original material. Species can often be identified by color and grain pattern — red oak has a bold, open grain with reddish tones; white oak is more golden with a tighter grain; maple is creamy white with a fine, uniform texture; walnut is dark brown with a straight, open grain. Once the species is identified, we can help you source matching stock. Profile matching may require a millwork shop to run a custom profile if the original is no longer a standard offering.

What is the standard thickness for hardwood trim?

The standard finished thickness for most interior hardwood trim — including base, casing, and crown — is ¾ inch (three-quarters of an inch). This thickness provides the right visual weight and structural integrity for most residential applications. Heavier profiles, such as large crown assemblies or thick base in formal rooms, may use 1" or 1¼" stock. Flat trim blanks for custom millwork are available in a range of thicknesses from ¾" through 2" and beyond.
