Trim is what makes a room look finished. Builder-grade homes across the DMV often have thin “clamshell” baseboard, flat door casing and no crown at all — and upgrading them is one of the most noticeable changes you can make without touching layout or plumbing. Good trim carpentry shows up everywhere, from interior crown to exterior details like the wrapped porch columns and trim in the photo above.
2026 TRIM INSTALLATION COSTS
| Trim Type | Installed (paint-grade) |
|---|---|
| Baseboard (3–5") | $4 – $9 / linear ft |
| Tall baseboard (6–8") or built-up base | $8 – $15 / linear ft |
| Crown molding (single piece) | $9 – $18 / linear ft |
| Built-up crown (2–3 pieces) | $18 – $35 / linear ft |
| Door or window casing | $90 – $220 per opening |
| Wainscoting / picture-frame molding | $25 – $60 / linear ft of wall |
An average 12×14 room has about 52 linear feet of perimeter — so new crown in a typical bedroom or dining room runs roughly $500–$950, and closer to $1,000–$1,800 for a built-up profile. Stain-grade hardwood trim costs significantly more than painted MDF or finger-jointed pine.
WHAT AFFECTS THE PRICE
- Wall and ceiling condition: older DMV homes rarely have square corners or flat ceilings. Coped joints, scribing and caulk are what make crown look tight on imperfect walls — and they take time.
- Ceiling height: above 9 feet, crown work needs more staging and is slower.
- Number of corners: a room with bump-outs and bay windows can have twice the cuts of a simple rectangle.
- Removal: taking off old trim carefully, especially without damaging plaster, adds labor.
- Painting: nail holes filled, joints caulked, primed and painted is often 30–40% of the total. Ask whether it's included.
MATERIAL CHOICES
MDF is smooth, stable and affordable — ideal for painted trim in dry rooms. Finger-jointed pine holds nails better and tolerates bathrooms a little more. Poplar is the premium paint-grade choice. PVC belongs outside and in wet areas — it's what we use to wrap porch columns and exterior trim because it won't rot.
SCALE MATTERS
The most common mistake is trim that's too small for the room. As a rough guide, crown should get larger as ceilings get taller: 3–4" for 8-foot ceilings, 5–7" for 9-foot, and larger or built-up profiles above that. Baseboard and crown should feel proportional to each other.
If budget is limited, upgrade trim in the rooms people see first — the entry, living and dining rooms — and do door casing throughout the main level for continuity. It reads as a whole-house upgrade for a fraction of the cost.
Trim pairs naturally with new interior doors (see our door installation cost guide) and with an accent wall or paneled feature wall.
