Plaster typically costs $3-$10 per square foot installed with materials, with an average near $6. Price depends on plaster type, wall condition, access, and local labor rates. Material alone often runs $0.50-$2.50 per square foot, before surface preparation and application.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Installed plaster | $3/sq ft | $6/sq ft | $10/sq ft | Standard interior wall, materials and labor |
| Materials only | $0.50/sq ft | $1.25/sq ft | $2.50/sq ft | Varies by plaster system and finish |
| 300 sq ft wall area | $900 | $1,800 | $3,000 | Installed, straightforward access |
| Repair and patching | $200 | $600 | $1,500 | Small jobs may have minimum charges |
What plaster installation costs per square foot
For new interior walls or full-wall resurfacing, a typical installed price is $3-$10 per square foot. A smooth, standard finish on sound walls often falls around $4-$7 per square foot; decorative finishes, multiple coats, or difficult access can push the rate higher. These estimates assume a professional crew and ordinary residential conditions.
For 500 square feet, budget roughly $2,000-$3,500 for a standard job, or up to $5,000 for more involved work. Contractors may price small repairs as a flat fee rather than using a square-foot rate, so a small patch can cost more per square foot than a full room.
Assumptions: U.S. residential interior, standard materials, typical access, and no major framing or moisture repairs.
How plaster materials and labor appear in a quote
Material pricing depends on whether the job uses traditional lime or gypsum plaster, veneer plaster over a suitable base, or a bonding product over existing surfaces. Labor usually represents the largest share because skilled application, layering, and finishing take time.
| Quote item | Low rate | Typical rate | High rate |
|---|---|---|---|
| Plaster and bonding materials | $0.50/sq ft | $1.25/sq ft | $2.50/sq ft |
| Application and finishing labor | $2.25/sq ft | $4.25/sq ft | $7/sq ft |
| Surface prep and protection | $0.25/sq ft | $0.75/sq ft | $2/sq ft |
| Removal and disposal, if needed | $1/sq ft | $2.50/sq ft | $5/sq ft |
Ask the contractor to separate materials, labor, preparation, and removal so competing estimates cover the same work. is a useful check when an estimate lists labor hours and an hourly rate; experienced plasterers may charge roughly $50-$100 per hour, depending on location and job complexity.
Wall height, plaster type, and damage change the rate
Wall size and condition can shift a quote substantially. A broad, unobstructed wall is generally faster per square foot than a room with many corners, windows, built-ins, or detailed trim. Ceilings, stairwells, and walls above 10 feet may require additional setup and slower overhead work.
Material and application also matter. A basic smooth finish is usually less costly than a polished, textured, or multi-coat finish. If more than 25% of a wall has loose plaster, cracks, or delamination, the contractor may recommend broader removal or reinforcement instead of patching each defect.
Get a separate price for repairs when damage extends beyond isolated areas. Water damage, mold, loose lath, or movement in the framing can require work beyond plastering and should be addressed before new material is applied.
Regional labor rates affect plaster prices across the U.S.
Prices vary with contractor availability, wages, and travel distance. Large metropolitan areas in the Northeast and West Coast can run about 15%-30% above the national midrange. Smaller Midwestern and Southern markets may be 5%-15% below it, although rural locations can have higher trip charges or fewer plaster specialists.
Compare local quotes rather than applying a national average directly to a project. For a standard $6-per-square-foot estimate, a 20% regional increase would put the comparable rate near $7.20 per square foot; a 10% decrease would put it near $5.40.
Three wall-size examples show likely project totals
A 200-square-foot bedroom wall with sound surfaces and a smooth finish could cost $800-$1,400 at $4-$7 per square foot. A 500-square-foot living-room project with moderate prep might run $2,500-$4,000 at $5-$8 per square foot. A 900-square-foot renovation requiring removal and replastering may reach $6,300-$10,800 at $7-$12 per square foot.
These examples exclude major framing repairs, painting, and unusual access equipment. Confirm whether the estimate includes protection for floors and furniture, cleanup, primer, and disposal, since those items may be listed separately.
Plaster versus drywall for new interior walls
Drywall installation commonly costs about $1.50-$3.50 per square foot for standard work, while plaster installation is often $3-$10 per square foot. Drywall is generally less expensive and quicker to install; plaster can provide a harder surface and a traditional finish, but repairs may require a specialist.
For a budget-driven new wall, drywall is often the lower-cost choice; for matching existing plaster, plaster may avoid an obvious finish mismatch. Compare the full scope, including taping, texture, finish level, and painting, rather than comparing only the board or plaster material price.
Reduce plaster costs by controlling prep and finish scope
Keep the project to sound surfaces where possible. Removing intact plaster adds labor, hauling, and disposal fees; ask whether a compatible overlay or localized repair is feasible before approving full removal. Clear furniture and wall hangings before the crew arrives if the contractor permits it.
Choose the finish before work begins and avoid paying for texture or polishing that the room does not need. Obtain at least three itemized bids, confirm minimum charges for small jobs, and schedule non-urgent work when local crews are less booked. Also check whether adjoining rooms can be completed together to reduce setup and travel costs.
