What Drives the Final Number
Up and down — the honest answer.
Pushes price up
- Stain-grade vs paint-grade material
- Premium profiles (custom-milled trim, large crown)
- Tall ceilings
- Inset doors / dovetail joinery on built-ins
- Integrated lighting in built-ins
- Existing wall conditions requiring drywall repair first
- Color match to existing aged trim (sometimes impossible)
Keeps price down
- Paint-grade poplar / MDF substrate
- Standard stock profiles
- Single-finish project (no two-tone stain)
- Off-the-shelf hardware
Common Cost Questions
Frequently asked
How much do built-ins cost?
Custom floating shelves $185/LF ($1,250 min). Fireplace mantel and surround $2,850 min (basic). Larger built-in bookcases / wall units price by the linear foot of run plus design complexity — bring a Pinterest reference and we'll quote against it at the site walk.
What about trim — baseboard, crown, wainscot?
Whole-home baseboard install + paint: $16/LF. Crown molding (paint-grade): $24/LF, $1,850 min. Board-and-batten / wainscot wall: $32/SF, $2,500 min. Slat / accent wall: $45/SF, $3,500 min. Single-room baseboard package: $1,250 min.
Doors and windows?
Interior prehung door install: $650 each. Solid-core / commercial door: $1,250 each. Exterior door replacement: $1,850 each. Standard window replacement: $950 each allowance.
Can you build to match my existing trim profile?
Usually yes — we source a matching stock profile or have it shop-milled if the original is unusual. A perfect match against aged wood is rarely achievable, but visual cohesion is what matters. We'll be straight about what level of match is realistic.
Painted or stained?
Both. Painted (poplar substrate, MDF for non-load-bearing faces) gives clean modern lines. Stain-grade (oak, walnut, white oak) shows grain and ages differently. Stain-grade material costs more and adds finish complexity — we bring samples to the consult.
Walls and drywall too?
Yes. Frame / drywall / paint small wall package: $3,500 min. Walls over 20 LF: $185/LF. Texture match: $2.50/SF wall area, $1,250 min. Popcorn ceiling removal: $4.50/SF ceiling area, $2,500 min.
