Plaster repair typically costs $5-$15 per square foot for a larger, straightforward repair, while small patches often work out to $10-$30 per square foot because contractors charge a minimum service fee. Plaster repair cost depends most on damaged area, whether the lath behind it needs work, ceiling height, finish matching, and local labor rates.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Small wall patch | $150 | $300 | $600 | Minimum charge can outweigh per-square-foot pricing |
| Larger wall repair | $5/sq ft | $10/sq ft | $15/sq ft | Sound lath and standard finish |
| Ceiling repair | $8/sq ft | $16/sq ft | $30/sq ft | Height and overhead work raise labor |
| Crack repair | $150 | $350 | $800 | Price depends on length and recurring movement |
Assumptions: U.S. residential work, standard interior plaster, accessible surfaces, and no major structural repairs.
What plaster repair costs for common wall and ceiling jobs
For a larger, localized wall repair, expect about $5-$15 per square foot, or roughly $250-$750 for 50 square feet. A small hole or isolated damaged area may cost $150-$600 total, even if it covers only a few square feet, because setup, patching, and finish work take a minimum amount of time.
For small jobs, the contractor’s minimum charge is often more useful than a per-square-foot estimate. Ceiling patches generally run higher, commonly $8-$30 per square foot, as overhead work takes longer and may require scaffolding or extra protection. Painting is often quoted separately.
How labor, plaster, and lath show up in the quote
A repair quote usually combines assessment and preparation, removal of loose material, patching, finish blending, and cleanup. The table shows typical component ranges for a moderate repair; actual line items vary, and contractors may quote a single bundled amount.
| Quote component | Typical range | Pricing basis | What it covers |
|---|---|---|---|
| Labor | $50-$100/hour | Hourly or bundled | Removal, patching, and finishing |
| Plaster and bonding materials | $20-$100 | Per repair | Compound, bonding agent, and mesh |
| Lath replacement | $2-$6/sq ft | Damaged area | Wood or metal backing where needed |
| Protection and disposal | $25-$150 | Per job | Dust control and debris removal |
| Primer and finish coat | $1-$4/sq ft | Finished area | Surface preparation; paint may cost extra |
Labor is commonly the largest variable, particularly when the damaged area must be opened and rebuilt.
Why lath condition and repair size change the price
Damage limited to the plaster surface costs less than a repair that reaches the lath. If more than about 1 square foot of lath is broken or detached, the contractor may need to remove additional plaster, secure or replace the backing, and apply multiple coats. That extra work can add $100-$500 or more, depending on access and the area exposed.
Very small repairs carry a higher effective rate per square foot than jobs over 20-30 square feet, where setup costs are spread across more area. Ceilings above 10 feet, intricate trim, and repairs near plumbing or electrical work can also add labor. Ask whether the estimate includes matching the surrounding texture and securing any loose plaster beyond the visible hole.
How long a plaster crew needs for patching and drying
A straightforward patch may require 2-5 labor hours, often split across visits because plaster needs time to set between coats. A 20-50-square-foot repair with damaged lath can take 1-3 workdays from preparation to finish, though drying time is not continuous crew labor.
At $50-$100 per labor hour, 4-8 billable hours represent roughly $200-$800 in labor before materials and any minimum charge. Confirm whether the quote prices labor by the hour or as a fixed project amount, and whether return visits are included.
How regional labor rates shift plaster repair estimates
Prices in major coastal cities and high-cost metro areas can run about 15%-35% above a national midpoint. Smaller cities and rural markets may be 10%-20% below it, although fewer contractors specializing in older plaster can limit savings. Travel charges are more likely for rural homes outside a contractor’s usual service area.
For example, a $400 patch estimate in a mid-cost market might reach $460-$540 in a high-cost metro, before unusual access or finish requirements. Compare quotes from contractors who regularly work with plaster, rather than comparing a plaster specialist with a drywall-only bid.
When removal, painting, or access adds to plaster costs
Removing loose plaster and bagging debris may add $50-$200 for a typical patch, with larger demolition areas costing more. Painting can add roughly $1-$4 per square foot for the repaired area, but matching an aged wall may require painting a full wall or ceiling. A painter may also have a minimum charge of $150-$300.
High ceilings, furniture protection, occupied rooms, and difficult access can increase labor or setup fees. Water-damaged plaster may need a moisture check and correction of the leak before repairs; otherwise, the new patch can fail. Check that the estimate identifies disposal, surface protection, primer, and paint as included or excluded items.
When plaster repair beats replacing the area with drywall
Repair is usually more economical when damage is localized and the surrounding plaster remains firmly attached. A small patch often totals $150-$600, while replacing a larger section with drywall may require demolition, new board, taping, finishing, debris removal, and repainting. That broader work can cost $8-$20 per square foot or more, depending on the room and finish.
For widespread loose plaster, recurring cracks, or damaged lath across several walls, a contractor should price both stabilization and replacement. Drywall may have a lower material cost, but preserving original plaster can avoid extensive demolition and maintain the existing wall thickness and trim alignment. Compare complete finished-wall prices, not just the cost of patch material or drywall sheets.
How to lower a plaster repair quote without cutting corners
Combine nearby patches into one visit, move furniture before the crew arrives, and request a clear limit on how far the contractor will remove sound plaster. Getting two or three itemized estimates helps reveal whether a price includes lath, texture matching, cleanup, and paint. Avoid delaying active water damage, since a larger affected area can increase the eventual bill.
For stable hairline cracks, ask whether a localized mesh-and-plaster repair is sufficient before agreeing to a full-wall skim coat. Skip repainting unaffected rooms, but budget for a full wall if color or sheen cannot be matched. The most reliable savings come from controlling repair scope while keeping necessary backing, moisture, and finish work in the estimate.
