A plasterer typically charges $200-$800 for a small repair, $800-$3,000 to plaster a standard room, or $5-$15 per sq ft for new plaster, depending on finish and access. The plasterer cost also changes with damage, wall height, regional labor rates, and whether old material must be removed.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Small plaster repair | $150 | $450 | $1,000 | Cracks, holes, or limited areas |
| Skim coat | $1.50/sq ft | $3/sq ft | $5/sq ft | Existing walls in usable condition |
| New plaster installation | $5/sq ft | $9/sq ft | $15/sq ft | Labor and standard materials |
| Standard room | $800 | $1,800 | $3,500 | About 400-600 sq ft of wall area |
What plastering a standard room usually costs
For a 12-by-12-foot room with 8-foot ceilings, plastering the walls generally costs $1,000-$2,800. The estimate assumes roughly 380 sq ft of wall surface, ordinary ceiling height, standard gypsum or lime-based materials, and no major substrate repairs. Adding a plaster ceiling can bring the total to $1,500-$4,000.
Skim coating an existing surface is less expensive than building a new plaster system. A basic smooth skim coat often runs $1.50-$5 per sq ft, while multi-coat plaster over lath or new board can reach $5-$15 per sq ft. For a typical room, budget about $1,800 before unusual repairs, premium finishes, or removal.
Assumptions: U.S. mid-market labor rates, standard finish, clear access, and no extensive water or structural damage.
How labor, plaster, and surface preparation shape the quote
A quote usually combines labor, plaster or finish materials, surface preparation, and sometimes equipment or disposal. Labor is often the largest component because plastering involves multiple passes, drying time, and skilled finishing. The table gives representative ranges for a 400-sq-ft wall project; actual invoices may bundle these charges.
| Quote item | Typical price | How it is charged | What changes it |
|---|---|---|---|
| Labor | $400-$1,400 | $50-$100 per hour | Finish quality and access |
| Plaster and bonding materials | $150-$600 | $0.40-$1.50 per sq ft | Product type and coat count |
| Prep and patching | $100-$700 | $1-$4 per sq ft affected | Cracks, loose areas, lath condition |
| Equipment and protection | $50-$250 | Per project | Room size and dust control needs |
| Removal and disposal | $300-$1,200 | $2-$6 per sq ft removed | Plaster thickness and debris access |
Ask whether preparation, materials, cleanup, and disposal are included before comparing totals.
How wall area, damage, and finish level change prices
Plasterers generally price by the measured surface area, not simply the room’s floor area. A 300-sq-ft wall area might cost $450-$1,500 for skim coating, but $1,500-$4,500 for a new multi-coat finish. Ceilings, stairwells, and walls above 10 feet often require extra setup and can add 10%-30% to labor.
Condition matters as much as square footage. Hairline cracks that need mesh and patch compound may add $100-$300; widespread loose plaster or failed lath can add $500-$2,000 or more. A smooth Level 5-style surface or decorative finish may cost 20%-50% more than a standard smooth finish. Measure wall and ceiling surfaces separately, and identify damaged areas before requesting a fixed quote.
When does repair cost less than replastering?
Localized repairs are usually economical when damage is limited to a few stable cracks, small holes, or a single section. A small patch may cost $150-$400, while a larger repair covering 20-50 sq ft can run $400-$1,200, including blending and finish work. Multiple scattered repairs may carry a minimum visit charge of $150-$300.
If more than 25%-30% of a wall is loose, hollow-sounding, or crumbling, a plasterer may recommend replastering that wall instead of patching repeatedly. Replastering one 150-sq-ft wall can cost $750-$2,250, before removal or lath replacement. Compare the repair quote with the cost of resurfacing the whole wall when damage is widespread.
What three plastering quotes look like in practice
These examples show how scope and labor hours affect a realistic estimate. They exclude major structural work and assume ordinary weekday scheduling.
- Crack repair: One 8-foot crack and two small holes, 3-5 labor hours at $60-$90 per hour, plus $40-$100 in materials; total about $250-$550.
- Room skim coat: 400 sq ft at $2.50-$4 per sq ft, with 18-26 labor hours; total about $1,000-$1,800 including standard prep.
- New plaster on walls: 500 sq ft at $7-$12 per sq ft, with 35-50 labor hours and multi-coat materials; total about $3,500-$6,000.
Differences in included prep and finish can explain why quotes for the same room vary by hundreds of dollars.
How plasterer rates vary between U.S. regions
Labor costs are commonly higher in major coastal cities and dense metropolitan areas than in smaller inland markets. Compared with a mid-market U.S. estimate, quotes may be 15%-30% higher in cities such as New York, San Francisco, or Boston, while rural markets may run 10%-20% lower. These are broad comparisons; local contractor availability and building age also matter.
Older Northeast and Mid-Atlantic homes may involve traditional lime plaster, fragile lath, or preservation requirements that increase labor. In regions with many newer homes, gypsum-based finishes may be more common and easier to price. Use local bids rather than a national average when setting a final budget.
Which extras can add to plastering charges?
Removing old plaster commonly adds $2-$6 per sq ft, while hauling away a small load may cost $100-$400. Extensive furniture protection, difficult stair access, or work in an occupied home can add $100-$500. A small job may also have a minimum charge even when the measured repair area is tiny.
Moisture damage should be fixed before new plaster is applied; otherwise, the finish may fail. Drying or leak repairs are typically separate trades and are not included in a plastering quote. Confirm who handles debris, room protection, and any underlying damage before work begins.
How to lower the plastering bill without cutting corners
Combine repairs in nearby rooms when possible, since one mobilization can cost less than separate visits. Clear furniture and wall hangings before the crew arrives, but leave delicate removal or substrate work to the contractor. Choose a standard smooth finish unless a premium texture or decorative treatment has a clear purpose.
Request at least three itemized quotes using the same wall measurements, finish, and preparation scope. Ask whether a skim coat will solve the problem or whether damaged plaster must be removed, and compare repair with replacement only where deterioration is substantial. Clear scope and comparable bids are the most reliable ways to control the final price.
