Common Questions

Finish Carpentry FAQ.

WHAT'S THE DIFFERENCE BETWEEN TRIM AND MOLDING?+
Great question. Trim is the catch-all term for all the wood that finishes transitions in your home—baseboards, door casings, crown molding, railings, wainscoting. Molding is a subset of trim, usually more decorative and ornate. Think of it this way: All molding is trim, but not all trim is molding. A simple baseboard is trim. An ornate crown molding at the ceiling is both trim and molding. For us, it's all finish carpentry—the final details that make your home look complete.
HOW MUCH DOES FINISH CARPENTRY COST?+
Finish carpentry pricing depends on three things: material, linear footage, and complexity. MATERIAL PRICING (per linear foot installed): - MDF or pine baseboard: $4.50–$6.00/lf - Solid wood crown molding: $5–$8/lf - Door/window casing: $5–$10/lf - Painting or stain finish: $1–$3/lf TYPICAL PROJECT COSTS: - One room (baseboards + crown): $1,500–$3,500 - Whole house trim: $3,500–$8,000 - Complex details (railings, built-ins, wainscoting): $8,000–$20,000+ Your exact quote depends on your home's size, wall condition, material choice, and finish preference. We always provide a detailed, itemized estimate.
HOW LONG DOES FINISH CARPENTRY TAKE?+
Timeline varies by scope: SINGLE ROOM (baseboards, crown, casings): 1–2 weeks WHOLE HOUSE TRIM: 2–4 weeks COMPLEX PROJECTS (railings, built-ins, wainscoting): 3–4+ weeks The timeline also depends on how quickly materials arrive (we order premium trim stock), whether we're painting on-site, and the complexity of your walls. Older homes sometimes take longer because walls aren't perfectly square or level— but we handle that with professional techniques like coping joints and shims. We always give you a firm schedule before we start, and we keep you updated throughout the project.
DO ALL MY TRIM COLORS AND STYLES HAVE TO MATCH?+
Not at all. You have complete creative control. Here are common approaches: FULL MATCH: Same trim color and style throughout the home. Creates a cohesive, unified look. Most popular choice. MIXED & MATCHED: Crown molding in one style, baseboards in another. Baseboards painted white, doors stained dark. Many modern homes do this beautifully. ROOM BY ROOM: Different trim styles in different rooms. Kitchen with simple flat stock, dining room with ornate crown. Works if the overall aesthetic ties together. CONTRAST: Paint trim in a contrasting color (like dark trim against white walls). Creates visual interest and architectural definition. Our job is to help you choose what looks best for your home and style. There are no trim rules—just design choices.
CAN YOU INSTALL TRIM IN AN OLDER HOME?+
Absolutely—and we specialize in it. Older Wisconsin homes built before 1980 often have walls and floors that aren't level or plumb. Corners aren't square. Plaster walls have character but challenges. HERE'S HOW WE HANDLE IT: - Precise measuring and layout to account for uneven walls - Shims and spacers to make trim sit flush and level - Coping joints (instead of simple miters) for better fit in uneven corners - Flexible fastening methods that work with plaster and old framing - Paint/caulk strategies that hide minor gaps while keeping trim looking clean We actually prefer older homes—the trim work is more skilled and rewarding. Your home's character is worth preserving with quality finish carpentry.
WHAT'S THE BEST MATERIAL FOR MY TRIM?+
It depends on your budget, style, and how you want it to finish: PAINT-GRADE (Budget-friendly): Pine or MDF. Very affordable, accepts paint beautifully, works everywhere. Best for baseboards and crown molding in painted rooms. $1–$3/lf. STAIN-GRADE (Mid-range): Solid pine or poplar stained. Shows wood grain and warmth. Works great in kitchens and living areas. $3–$6/lf. HARDWOOD (Premium): Oak, maple, or walnut. High-end look. Rich grain and character. More expensive but timeless. $6–$12+/lf. CUSTOM PROFILES: Want something unique? We can source or mill custom trim. Higher cost but your home looks one-of-a-kind. OUR RECOMMENDATION: Match your material to your home's style and budget. If you love wood, go hardwood. If clean and simple appeals to you, paint-grade MDF is perfect. We help you choose during your free consultation.
DO YOU PAINT THE TRIM BEFORE OR AFTER INSTALLATION?+
We typically paint AFTER installation for the cleanest finish. Here's why: PAINT AFTER INSTALLATION: - We install trim, seal nail holes and joints with caulk - Prime and paint on-site for seamless, professional finish - No chipping or damage during transport or installation - Paint edges match perfectly with wall paint SOMETIMES WE PRIME BEFORE: - For stain-grade wood, we may pre-stain before installing - For large primer jobs, some stain work happens in the shop Either way, you get a flawless, finished look. We use high-quality paint (satin or semi-gloss finish) that's durable and easy to clean. Your trim will look great and stay looking great.
