The per-linear-foot math: $5-$8 national, $6-$9 coastal CA

HomeYou's October 2026 per-city calculators land the installed band at $5 to $8 per linear foot in most markets, rising to $6 to $9 in coastal California -- both coastal California calculator cities quote $280 to $471 for the standard 54-linear-foot job: molding material, install labor, finishing supplies, and equipment.

The 54-linear-foot reference job is the industry's standard room: roughly a 12-by-12 room at the ceiling line plus waste. At the national band that prices $268 to $424; at the coastal California band, $280 to $471. Your number moves with material choice, room count, and how much cutting each corner demands -- every outside corner and mitered joint adds labor minutes.

Material tiers: MDF to plaster ($1-$12 per foot)

Material-only pricing spans wider than the installed band. Medium-density fiberboard (MDF) is the budget workhorse at $1 to $3 per linear foot: paint-grade and uniform. Poplar runs $2 to $3, maple $2 to $5, and cherry $4 to $6 -- exotic species stretch to $10 to $45.

Polystyrene foam moldings price $1 to $12 per foot. Plaster moldings price $6 to $12 per foot before labor and demand professional handling: plaster is brittle, heavy, and unforgiving of imperfect walls. Paint-grade MDF for painted installs, wood where the finish will be stained, plaster only where the architecture demands it.

The four lines: material, labor, finishing, equipment

Every quote is four lines. The molding-material line runs $100 to $170 for the standard 54-foot job in 2026 calculator data -- the spread is material choice, not market mystery. The labor line runs $75 to $185: about 2.8 hours of carpenter time at $2 to $6 per linear foot. Job materials and supplies -- caulk, filler, fasteners, sandpaper -- add $20 to $27. Equipment allowance adds $61 to $92.

The finishing line is the one owners forget: crown arrives raw or pre-primed, and the final look needs caulking at the ceiling and wall joints, nail-hole filling, and two paint coats. Some quotes bundle finishing; others price it on top. Confirm finishing is in the line before comparing quotes.

Room math: one room vs. whole-house

The single-room number is modest; the whole-house number is where the per-foot band earns its keep. A 12-by-12 room needs roughly 48 linear feet at the ceiling line -- 54 feet purchased with the standard waste factor. At $6 to $9 installed, that room prices $288 to $486 -- under $500 for the room's entire perimeter in the coastal band.

Scale it to a 2,000-square-foot home: ceilings on every room typically total 250 to 350 linear feet, pricing $1,500 to $3,150 installed at the OC band. The per-foot rate often drops as the job grows -- mobilization spreads across more footage -- so whole-house quotes frequently beat the per-room math by 10 to 20 percent. Whole-house quotes typically beat per-room math by 10 to 20 percent.

The Orange County angle: labor premium, paint-grade preference

Orange County prices the high side of every band: coastal labor markets carry demand premiums, and skilled finish carpenters price above band mids. The California calculator cities are the proof: $6 to $9 per foot installed against $5 to $8 nationally, with labor lines running $87 to $185 for the standard job. Scheduling also prices in -- finish carpenters book out in remodeling season, and rush scheduling stretches totals.

The OC material preference skews paint-grade: pre-primed MDF and poplar dominate because the finish is paint, not stain, in most tract and custom homes -- and paint-grade material sits at the bottom of the material band ($1 to $3 per foot). Tall ceilings add a scaffold line low ceilings never trigger.

DIY vs. hiring a pro

The owner-done lanes are finishing and simple runs: caulking, nail-hole filling, and paint on installed molding -- plus straight-run installs of paint-grade MDF in low-ceiling rooms for owners who own a compound miter saw. Two-piece built-up profiles, plaster, tall ceilings, and whole-house footage are the pro lanes: coping, miter math, and overhead precision.

What drives the price up or down

Material tier -- MDF $1-$3 vs. wood $2-$6 vs. plaster $6-$12
Profile size and complexity -- bigger profiles, harder cuts
Linear footage -- whole-house beats per-room math
Corner count -- outside corners add labor minutes
Labor band -- $2 to $6 per linear foot
Finishing line -- caulk, filler, and paint bundled or not
OC labor premium -- coastal rates above band mids
Ceiling height -- scaffold line on tall ceilings

How to keep the cost down

Price the whole project before room-by-room: the second room is cheaper per foot
Choose paint-grade MDF when the finish is paint: $1-$3/lf material
Confirm finishing (caulk, filler, paint) is in the quote line
Combine with interior painting: shared prep and finish labor
