Frequently Asked
'Custom Millwork' Questions
The best wood species depend on your goals for durability, budget, and appearance. Poplar and paint-grade maple are popular for painted trim and cabinetry because they’re smooth and cost-effective. For stained millwork, oak, walnut, and cherry are common choices due to their attractive grain and hardness. It’s also worth considering engineered products like MDF for stable, paint-grade profiles in low-moisture areas.
Champaign experiences humid summers and dry, cold winters, so you’ll want materials that handle seasonal expansion and contraction well. Solid hardwoods perform best when properly acclimated indoors before installation and sealed on all sides. Engineered materials like MDF or finger-jointed trim can be more stable for interior applications, while exterior millwork should use weather-resistant species and finishes. Always allow time for materials to adjust to indoor conditions before cutting and installing.
Start by acclimating your millwork in the room where it will be installed for at least 48–72 hours. Use a moisture meter to verify that the wood’s moisture content matches the home’s environment as closely as possible. Fasten pieces securely into framing, not just drywall, and leave small expansion gaps where appropriate, especially on larger panels or long runs of trim. Finish all sides, including back and cut ends, to help seal out moisture and reduce movement.
MDF is smooth, stable, and great for detailed painted profiles, but it’s more vulnerable to moisture and impact damage than solid wood. Solid hardwoods offer superior strength and a premium feel, and they can be stained or painted, but they’re more expensive and move more with humidity changes. Engineered wood (like finger-jointed or laminated products) balances cost, stability, and performance, making it a strong choice for long runs of trim. In a climate with seasonal swings, many homeowners mix materials—using MDF for interior painted trim and engineered or solid wood where extra durability is needed.
