Interior trim is where construction technique becomes visible to everyone who walks through your home. Properly installed trim — coped inside corners, mitered outside corners, cleanly scribed to irregular walls — requires patience and skill. Trim installed with butt joints at inside corners, gaps that rely entirely on caulk to disappear, or baseboard that steps away from the wall before it reaches the corner is a permanent reminder of who built it. VResh Construction installs interior trim with the same attention to technique that we bring to exterior work.

Interior Trim Services We Offer

Crown Molding

Crown molding at the ceiling-wall intersection is one of the highest-impact trim upgrades available — it visually raises ceiling height, adds architectural character, and is a hallmark of high-quality interior finish. Crown molding installation requires accurate compound miter cuts at inside and outside corners and careful scribing to walls and ceilings that are rarely perfectly flat.

We install flat-profile crown, bed molding, and built-up crown assemblies (combining multiple profiles for a more substantial appearance). Profile selection is guided by the architectural character of the room and the scale of the space.

For rooms with out-of-square corners or wavy walls — common in Portland's older bungalows and ranch homes — we use blocking and scribing techniques rather than gaps covered with caulk.

Base Molding and Baseboard

The baseboard covers the gap between the finished floor and the wall, and is one of the most visible trim elements in any interior. We install baseboard profiles from standard colonial and ranch profiles to custom tall baseboards with built-up cap moldings.

All inside corners are coped, not butt-jointed. Coped corners stay tight as the wood moves seasonally — butt-jointed inside corners open up and require constant recaulking.

We scribe baseboard to irregular floors and walls rather than relying on caulk to fill gaps. On older Portland homes with plank subfloor and settled framing, careful scribing is essential for a clean result.

Door and Window Casing

Interior door and window casing frames the opening and covers the gap between the jamb and the rough framing. It is the trim most homeowners see most often — and where trim quality is most visible.

We install all standard casing profiles — colonial, craftsman, modern flat, and custom profiles. For homes with existing casing that needs to be matched — for a new door, an addition, or a replacement — we stock and source matching profiles.

Window casings include stool and apron at the sill in addition to the side and head casings. Properly fitted stool and apron are a sign of quality finish work; most budget installations omit them in favor of a simple picture-frame casing all around.

Wainscoting and Board-and-Batten

Wainscoting — applied panels covering the lower portion of a wall, typically from floor to chair-rail height — adds significant character to dining rooms, hallways, and entryways. We install traditional raised-panel, flat-panel, and beadboard wainscoting.

Board-and-batten, either on interior accent walls or as a full-height treatment, is a currently popular design choice we install throughout Portland homes.

Chair rail molding, picture rail, and built-up panel molding assemblies are all part of our trim capability.

Stair Treads, Handrails, and Newel Posts

Stair trim — oak or other hardwood treads, painted or stained handrails, newel posts, and baluster assemblies — combines millwork and carpentry skills. We install and repair stair trim as part of interior remodeling projects.

For stairs transitioning from carpet to hardwood, we replace the original pine treads with hardwood treads, refinish or replace the handrail, and provide a complete interior stair finish.

OUR FAQS

Interior Trim Installation FAQs — Portland Homeowners

How much does interior trim installation cost in Portland, OR?
+
Interior trim costs vary significantly by project scope, profile complexity, and whether ceilings are high or irregular. Base molding installation typically runs $3–$6 per linear foot installed. Crown molding installation runs $6–$14 per linear foot depending on profile size and ceiling complexity. Door casing per opening typically runs $200–$400 per door. Full-room trim packages including base, crown, and door casings for a typical Portland living room usually run $1,200–$3,500.
Can you match my existing trim profile for an addition or repair?
+
In most cases, yes. Standard colonial, ranch, craftsman, and ogee profiles are widely available. For older Portland bungalow profiles from the 1910s–1930s Craftsman homes, we source matching profiles through millwork suppliers and architectural salvage. If an exact match cannot be achieved, we advise you on the closest available option before ordering materials.
Do you paint the trim, or just install it?
+
We install trim and leave it paint-ready — filled, sanded, and primed — unless you specifically want us to apply the finish paint. Many homeowners already have a painter scheduled or prefer to paint themselves. If you want us to apply the finish coat, we can include it in the project estimate.
Can you repair existing trim rather than replacing it?
+
Yes. For trim damaged in a single location — such as a dented section of crown molding or a cracked baseboard corner — spot repair and refinishing is often practical. If the repair will still be visible, we explain that upfront. When trim is extensively damaged, warped, or outdated, full replacement is usually the better long-term option.
What is the difference between MDF and solid wood trim?
+
MDF (medium-density fiberboard) is the most common material for paint-grade trim because it machines cleanly and holds paint well. It is stable and does not twist or cup, but it is vulnerable to moisture at exposed edges. Solid wood is preferred for stain-grade trim or humid areas like bathrooms. In Portland homes, MDF is usually used for painted trim, while solid wood such as poplar, oak, or Douglas fir is used where natural grain or moisture resistance is needed.
We just had new windows installed — can you do the interior trim around them?
+
Yes. Window replacement projects commonly require new interior casing, stool, and apron trim. We frequently install interior trim immediately after new window installations to finish the opening cleanly and match the surrounding trim style.
Can you install crown molding on vaulted ceilings?
+
Yes, though crown molding on vaulted ceilings requires compound miter cuts calculated specifically for the ceiling angle and crown profile. We measure the vault at multiple points to ensure precise cuts and clean joints, since many vaulted ceilings are not framed perfectly consistently.
