Frequently Asked
'Custom Millwork' Questions
Common choices for custom millwork include poplar, maple, oak, and cherry, each with different strengths and appearances. Poplar is cost-effective and great for painted finishes, while maple and oak are harder and more durable for high-traffic areas. Cherry offers a rich, warm tone that stains beautifully for more formal spaces. The best choice depends on whether you plan to paint or stain, your budget, and how much wear the surfaces will see.
Pontiac experiences seasonal temperature swings and humidity changes, which can cause natural wood to expand and contract. For areas prone to moisture, like basements or near exterior doors, you may want to consider engineered wood or MDF for more stability. Using properly kiln-dried lumber and sealing all sides of the material helps reduce warping and cracking. It’s also wise to let millwork acclimate indoors for a few days before installation.
Always start by checking that walls and ceilings are reasonably straight and use a level and stud finder to secure heavier pieces. Pre-priming and lightly sanding trim before installation helps paint adhere better and creates a smoother finish. Use construction adhesive along with finish nails for a stronger hold and to minimize gaps over time. Finally, fill nail holes and caulk joints before painting to get clean, seamless lines.
MDF is smooth, budget-friendly, and ideal for painted trim, but it’s less moisture-resistant and not as strong as hardwood. Solid hardwood offers superior durability, better impact resistance, and a premium look, especially when stained, but it costs more. Engineered wood combines layers of real wood with a stable core, making it more resistant to warping from Pontiac’s seasonal humidity shifts. Your choice depends on where the millwork will be installed, how you plan to finish it, and your long-term durability needs.
