The typical price to plaster a room in the United States depends on room size, wall type, and finish quality. Common cost drivers include material choices, repair needs, labor rates, and disposal or permit requirements. The following guide provides practical, ballpark ranges in USD to help plan a plastering project.
Assumptions: room size 120–180 sq ft, standard interior walls, average ceiling height, basic smooth finish, no major repairs.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Plastering (material + labor) | $2,400 | $4,200 | $7,000 | Includes plaster mix, tapes, and basic finish |
| Repairs & Surface Prep | $300 | $1,000 | $2,000 | Cracks, damp spots, or skim repair |
| Finishing & Texture Options | $200 | $1,000 | $3,000 | Skim coat, orange peel, or knockdown |
| Preparation & Cleanup | $150 | $500 | $1,200 | Drop cloths, debris removal |
| Permits & Inspections | $0 | $250 | $1,000 | Depends on jurisdiction and scope |
Overview Of Costs
Cost ranges reflect typical interior plastering projects for a standard room. The total project often includes materials, labor, and basic finishing, with per-square-foot estimates spreading across small to mid-size rooms. For planning, consider square-foot pricing and project-wide estimates.
Cost Breakdown
| Cost Component | Low | Average | High | Notes |
|---|---|---|---|---|
| Materials | $1,000 | $2,000 | $3,500 | Plaster mix, lath, mesh, bonding agents |
| Labor | $1,600 | $2,800 | $4,000 | Skilled plasterer; room size and finish impact hours |
| Equipment | $100 | $300 | $800 | Mixers, scaffolding, float tools |
| Permits | $0 | $250 | $1,000 | Regional requirement varies |
| Delivery/Disposal | $50 | $250 | $700 | Waste removal and material transport |
| Contingency | $100 | $500 | $1,200 | cushion for unexpected issues |
| Taxes | $0 | $180 | $900 | State/local taxes where applicable |
What Drives Price
Room size, wall condition, and finish quality are primary price drivers. Larger rooms add materials and labor, while damaged or uneven substrates raise prep time. Finish texture choices (smooth vs. textured) influence sanding, coating, and drying cycles.
Pricing Variables
Regional differences and crew availability affect quotes. Sealed ceilings, high ceilings, or intricate crown molding raise costs. The need for moisture mitigation in bathrooms or kitchens also shifts pricing upward due to additional preparation and materials.
Ways To Save
Get multiple bids and specify finish type upfront. A straightforward skim coat or simple smooth finish costs less than decorative textures or specialized plaster types. Scheduling during off-peak seasons may yield modest savings on labor.
Regional Price Differences
Prices vary by market, with notable differences between metro areas and rural counties. In the Northeast, labor rates can be higher due to cost of living, while the Midwest may show lower labor hours but similar material costs. The South often presents mid-range pricing, with some regions cheaper for material supply. A typical regional spread could be +/- 15–25% from national averages depending on demand and availability.
Labor & Installation Time
Labor costs hinge on crew size and wall complexity. A standard room may require 8–14 hours of skilled plastering, plus prep and cleanup. For multi-room projects, crews may operate in parallel, reducing per-room labor hours but potentially increasing mobilization costs. Expect hourly rates in the $60–$110 range in most markets, with premium specialists charging higher for special finishes.
Additional & Hidden Costs
Hidden costs can surprise if not anticipated. Structural repairs, moisture mitigation, or insulation adjustments add to the base price. Access constraints (tight openings, crawl spaces) can require extra equipment rental. After-project touch-ups or warranty considerations may also affect the long-term budget.
