Interior Trim Carpentry in Missoula, MT

The detail that makes a house feel finished.

Baseboards, casing, crown, wainscot, mantels. Tight miters, clean reveals, painted-grade or stained-grade.

About this service

Interior trim is the layer most clients notice last but feel first. A house with tight miters at every corner just feels right. A house with gaps and uneven reveals feels off — even if you can't say why.

We build casing on site, set crown that follows real walls (not the ones in the drawing), and scribe baseboard to floor. Painted-grade gets caulk; stained-grade gets dowels and glue. No nail-pop showthrough after paint.

What's included

Door and window casing
Baseboard and shoe
Crown molding
Wainscot, beadboard, and panel walls
Mantels and built-ins
Stair skirts and balustrades
Coffered and box-beam ceilings

The honest take

Painted trim is faster and cheaper because we caulk the joints. Stained trim takes longer because every joint has to be tight without caulk to hide it. We'll quote both so you can make the call.

Interior Trim in Missoula & Western Montana

Most of the homes we trim in Missoula and the Bitterroot are some combination of mountain-modern, craftsman, or transitional — meaning the trim profiles matter more than they do in builder-grade subdivisions. Wide casing, beefier baseboard, square or beveled crown, real wainscot in entries and dining rooms, custom mantels around stone or steel fireplaces. We do both painted-grade (MDF or paint-grade pine with caulked joints) and stained-grade (solid hardwood — oak, maple, alder, walnut) where the joints have to be tight without caulk to hide them.

On remodels in older Missoula homes, profile-matching matters. Older trim was milled to spec and the modern off-the-shelf profiles don't always match. We source from specialty suppliers or have profiles milled custom when the existing trim is worth preserving.

Common project types

Whole-home trim packages — Base, case, crown, doors, windows on new custom builds.
Single-room trim upgrades — Crown, wainscot, picture-rail in living and dining rooms.
Built-ins and millwork — Bookshelves, window seats, mudroom lockers, closet systems.
Mantels and fireplace surrounds — Stained timber or painted shaker around stone or tile.
Stair trim — Skirts, treads, risers, balustrades, newel posts.

FAQ

Interior Trim — frequently asked questions.

What's the difference between painted-grade and stained-grade trim?

Painted-grade uses MDF or paint-grade pine. Joints get caulked, gaps filled, all imperfections hidden under paint. Stained-grade uses solid hardwood (oak, maple, alder, walnut) for a natural stained finish — joints have to be tight without caulk because the grain and stain show every gap. Stained costs more in material and labor but looks higher-end.

Can you match existing trim in an older home?

Usually yes. Older trim profiles can be sourced from specialty suppliers (Schwartz Brothers, classic-trim shops) or milled custom by local millwork houses. We've matched profiles in Missoula homes from the 1920s onward. If a profile truly can't be matched, we'll tell you up front.

How long does whole-home trim work take?

2–4 weeks for an average single-family home, depending on size, ceiling heights, and detail level (crown vs no crown, wainscot, coffered ceilings). Stained-grade takes longer than painted-grade because of the no-caulk requirement.

Do you do crown molding and built-ins?

Yes. Crown, coffered ceilings, wainscoting, mantels, and built-in cabinetry/shelving are all in scope. Custom mantels around stone fireplaces, mudroom lockers, and window-seat built-ins are some of our most-requested work.
