Interior Trim Installation Boulder

Interior Trim Services We Provide

CROWN MOLDING INSTALLATION

Crown molding adds elegance where walls meet ceilings. We install crown molding in all profiles—from simple colonial to elaborate multi-piece designs. Crown molding requires precise angle cuts and coping for seamless inside corners. We handle the complexity so you get perfect results. For Boulder homes with 9-foot or cathedral ceilings, crown molding makes a dramatic impact.

DOOR CASING AND WINDOW TRIM

Door casing and window trim frame your openings and hide gaps between frames and walls. We install new door casing during renovations and replace damaged or outdated trim. Window trim takes a beating from condensation and sun exposure—we see a lot of failed window trim in Boulder homes. For older properties, we can match existing historic profiles or update to cleaner modern styles.

CHAIR RAIL AND PICTURE RAIL

Chair rail protects walls and adds visual interest at chair-back height. Picture rail lets you hang art without nail holes in plaster. Both are popular in Boulder's historic neighborhoods. We install new chair rail and repair damaged sections to maintain your home's character.

WAINSCOTING AND PANEL MOLDING

Wainscoting adds character to dining rooms, hallways, and bathrooms. We install beadboard, raised-panel, and flat-panel wainscoting with proper cap and base molding. Panel molding creates elegant wall frames without full wainscoting.

Trim Repair and Replacement

ROTTEN TRIM REPLACEMENT

Colorado's dry climate is actually hard on interior trim. Moisture from bathrooms, kitchens, and exterior walls can cause trim to rot—especially around windows, doors, and plumbing. We remove rotten trim completely, address the moisture source, and install matching replacement trim. Ignoring rotten trim lets water damage spread to framing.

DAMAGED TRIM REPAIR

Dents, cracks, gaps, and paint failure make trim look tired. We repair minor damage with wood filler and refinishing. For significant damage, we replace trim sections and blend with existing trim through careful painting or staining.

HISTORIC TRIM MATCHING

Boulder's older homes often have trim profiles that aren't available at Home Depot. We work with local millwork shops to match historic profiles or can create custom trim using router bits. Maintaining original architectural character matters—we'll find or make what you need.

Our Trim Installation Process

1. Consultation: We discuss your vision, measure spaces, and review trim options. We bring samples of common profiles.

2. Material Selection: We help you choose between solid wood, MDF, and composite trim based on location, paint vs. stain finish, and budget.

3. Preparation: We prepare walls, remove old trim if replacing, and address any underlying issues (uneven walls, gaps, damage).

4. Installation: Precision cutting, proper nailing, and tight joints. Crown molding gets coped inside corners for seamless results.

5. Finishing: Nail holes filled, caulking at wall joints, touch-up paint or stain as needed. We leave your space clean.

Trim Material Options

SOLID WOOD

Best for: Stained finishes, historic matching, high-end projects. Pine, poplar, oak, and MDF-core options available. More expensive but takes stain beautifully and feels substantial.

MDF (Medium-Density Fiberboard)

Best for: Painted trim on a budget. Smooth, consistent surface paints beautifully. Won't warp or show wood grain through paint. Not suitable for wet areas or staining.

PVC/COMPOSITE

Best for: Bathrooms, basements, areas with moisture. Won't rot, warp, or swell. More expensive than MDF but maintenance-free. Limited profiles available.

FAQ

How long does it take to install crown molding in a room?

A standard 12x12 room takes 3-5 hours for crown molding installation, including cutting, fitting, and finishing. Complex profiles, cathedral ceilings, or rooms with many corners take longer.

Should I use MDF or wood trim?

For painted trim, MDF is usually the better value—it paints smoothly and costs less. For stained trim or historic matching, solid wood is preferred. For bathrooms and wet areas, consider PVC or composite.

Can you match my existing trim profile?

Usually yes. We can match most standard profiles from lumber suppliers. For unusual or historic profiles, we work with local millwork shops for custom matching. We'll bring a sample to verify the match before ordering materials.

How do you handle uneven walls?

Older Boulder homes often have walls that aren't perfectly flat or square. We scribe trim to follow wall contours, use flexible caulk to fill gaps, and back-cut molding as needed. The result looks seamless even when walls aren't perfect.

Do I need to paint the trim after installation?

Primed trim needs painting after installation. We fill nail holes and caulk joints, but typically leave final painting to you or your painter. For smaller jobs, we can include painting—just ask.
