Architectural millwork: a curved wooden staircase and railings

Millwork covers the profiled wood that finishes a building: casing, base and crown mouldings, stair parts, window and door components and wall paneling. Distributors, home centers, builders and door and window makers buy it in long runs of standard profiles. Fit-out contractors buy architectural millwork per project, from reception desks to wall panels and store fixtures.

Most mouldings are either stain grade, cut from clear solid wood, or paint grade, made from finger-jointed stock or MDF and often primed at the plant. Paint grade costs less and stays straighter. Stain grade shows the wood and needs clear, color-matched stock. Architectural millwork adds shop drawings, veneered panels, joinery and finishing, so it is quoted as a project rather than per foot.

What this covers

  • Casing, base and crown mouldings
  • Finger-jointed primed mouldings
  • Stair treads, risers, handrails, balusters and newel posts
  • Window and door components: jambs, stops, sills, stiles and rails
  • Wall paneling, wainscot and shiplap
  • Architectural millwork for commercial fit-out

Order size
Moulding programs run on repeat by the container, priced per linear foot or meter, with a minimum per profile because each profile needs its own knives. Architectural millwork is ordered per project and quoted from shop drawings.
Rules
  • TSCA Title VI for MDF mouldings and composite wood panels sold in the US
  • Fire performance for commercial interiors: building codes set flame spread classes for wall finishes, tested to ASTM E84 in the US. Confirm with the architect.
  • Lacey Act: wood imported into the US must be legally sourced, and many product codes need a plant product declaration. Confirm with your customs broker.
  • EUDR due diligence for wood placed on the EU market

Millwork and mouldings by product line

Each line has its own page with typical specs, species, construction options and the RFQ checklist factories quote from.

Primed finger-jointed mouldings

Casing, base, crown, stops and trim run from finger-jointed pine blanks, primed with gesso or acrylic, cut to length and bundled for distributors and builders.

Stair parts

Treads, risers, handrails, balusters, newel posts and fittings for interior stairs, in stain grade oak and maple or paint grade poplar, made to your profiles and sizes.

Wood slat wall panels

Acoustic slat panels with veneered MDF slats on felt backing, solid wood slat panels and battens on a board, made to size for offices, hotels, shops and homes.

How it is built

  • Clear solidOne piece of clear wood per length. Used for stain grade trim and visible stair parts.
  • Finger-jointed and primedShort clear pieces joined into long lengths, profiled and primed. Straight and stable, paint grade only.
  • MDF mouldingsProfiled from MDF and primed. Smooth for paint, but not for wet areas or exterior use.
  • Laminated or veneered blanksGlued cores with a clear face for door stiles, jambs and wide treads. Straighter than solid in long or wide parts.

What to send for a quote

  1. A profile drawing or a physical sample for each profile, with dimensions and tolerances
  2. Species and grade, finger-jointed stock or MDF, plus primer type and number of coats
  3. Lengths: fixed lengths or random lengths with a minimum length
  4. Quantity per profile in linear feet or meters
  5. For architectural millwork: shop drawings, finish schedule and the project timeline
  6. Bundling, end sealing and labels per bundle

Where orders go wrong

  • Profile drift between runsKnives wear and get reground, so the second container may not match the first at a miter. Ask the plant to keep a master sample and the knives for your profiles.
  • Finger joints showing through paintWet stock or poor primer lets joints telegraph after painting. Ask for moisture checks before jointing and a painted sample after a few weeks.
  • Shrinkage after installationMouldings installed wetter than the building open at miters. Give a target moisture content for the market and keep bundles wrapped until use.
  • Short lengthsToo many short pieces raise waste for installers. State the minimum length and the share of short lengths allowed.

Do I pay for knives for a custom moulding profile?

Usually yes. Each new profile needs its own knife set, so expect a one-time charge or a minimum quantity that covers it. Ask who keeps the knives, how long they are stored and whether repeat orders reuse them, so later runs match the first.

Should I order stain grade or paint grade millwork?

Choose stain grade when the wood will show: it needs clear, color-matched solid stock and costs more. Paint grade from finger-jointed stock or MDF is straighter, more stable and lower in cost. It often ships primed. Many projects mix both, with stain grade only where it is seen up close.

What moisture content should interior millwork ship at?

Ask for a target that matches the building it goes into. For heated interiors in most of the US, a typical target is about 6 to 9 percent, and humid regions run higher. Keep bundles wrapped until installation so the wood does not pick up moisture on site.

Can one factory handle architectural millwork for a commercial project?

Some can, if they work from shop drawings and can veneer, assemble and finish in-house. Send the drawings, finish schedule and project timeline. Say who installs, since installation is usually done by a local contractor. We match you with factories that take projects of that scope.
