Quick Answer
Finished wood products like trim, molding, cabinetry, and doors that give a building its interior character.
Definition
Definition
Millwork refers to finished wood products manufactured in a mill and used for interior architectural elements, including doors, windows, casings, baseboards, crown molding, wainscoting, cabinetry, and custom trim. Millwork is distinguished from rough lumber by its finished, decorative quality. Custom millwork is fabricated to project-specific dimensions and profiles, while stock millwork is available in standard sizes.
Context
Why It Matters in Bidding
Custom millwork is often a long-lead, shop-drawing-dependent scope, so estimators must price not just material and install but also detailing, finishing, and field measurement, then protect the schedule with realistic fabrication lead times. Because millwork is highly visible, allowances and finish-grade assumptions drive both cost and owner satisfaction, making vague specs a frequent source of change orders.
Example
Example
Pricing a bank lobby, the estimator carried a custom-millwork allowance for the quarter-sawn oak reception desk and field-verified casework, knowing shop drawings and a long fabrication lead time would gate the finish schedule.

FAQ
Questions Contractors Ask
What is the difference between stock and custom millwork in a bid?
Stock millwork uses standard profiles and sizes available off the shelf, so it is cheaper and faster. Custom millwork is fabricated to project-specific dimensions, profiles, and finishes, requiring shop drawings, field measurement, and longer lead times. Estimators should price each per the spec, since assuming stock where custom is required can badly understate cost.
Why do millwork lead times matter to the project schedule?
Custom casework and trim require approved shop drawings and shop fabrication before delivery, so the clock often starts only after award and submittal approval. Long lead times can make millwork a critical-path finish item, so estimators and PMs should release it early and flag fabrication duration as a schedule milestone.
How do finish grades affect millwork pricing?
Architectural woodwork grades, commonly economy, custom, and premium, set tolerances, material quality, and joinery, which directly change cost. A premium-grade veneer-matched panel costs far more than a custom-grade painted casework run. Estimators should confirm the specified grade and any AWI quality reference before pricing to avoid bidding the wrong level of finish.
