What plaster repair costs in 2026
Plaster repair is priced by what the damage needs. A surface repair fills and blends the damaged area. A full repair removes loose plaster and rebuilds it from the lath. These are Angi's national averages, updated July 2026.
| Repair | Average cost | Type |
|---|---|---|
| 3-inch hole | $50 | surface repair |
| 5-inch crack | $90 | surface repair |
| 1-foot-wide dent | $130 | surface repair |
| 48-inch crack | $180 | surface repair |
| 6-foot foundation crack | $680 | full repair, foundation work not included |
| 4-foot-wide water damage | $1,200 | full repair |
| 5 by 3 foot section | $1,350 | full repair |
| 8 feet of sagging plaster | $1,900 | full repair |
Angi notes that many pros set a minimum charge, so a single small crack can cost more than its line above. It puts plaster repair labor at $55 to $120 per hour, and ceiling plaster at up to $100 to $120 per square foot because overhead work is slower.
San Jose estimates by ZIP code
Homewyse adjusts its calculators for local labor. With the ZIP code set to 95125 (Willow Glen), its September 2026 estimates include local labor, supplies and a four-hour minimum labor charge. The national default for a wall plaster repair on the same page is $312 to $492.
| Job (Homewyse, ZIP 95125) | San Jose estimate | Notes |
|---|---|---|
| Wall plaster repair | $543 to $656 | per repair |
| Plaster crack repair | $533 to $644 | per repair |
| Ceiling plaster repair | $543 to $656 | per patch |
| Paint the patched area | add $143 to $173 | up to 4 sq ft, color and sheen matched |
The minimum charge is most of the price on a single small repair. Homewyse notes the unused part of that minimum can go to other tasks, so fixing several cracks in one visit costs far less per crack than booking them separately. Want a real number? Send a photo and get a plaster repair quote.
Is it plaster or drywall?
Many older San Jose homes, especially in Willow Glen and the Rose Garden, have plaster walls and ceilings rather than drywall. It changes the repair, so it helps to know which you have before you ask for a quote.
- Look at an edge. Take a switch plate off and look at the cut edge. Drywall shows a paper face over a chalky gypsum core. Plaster shows hard layers, often over wood strips (lath) or a gypsum board base.
- Press a pushpin. It goes into drywall easily. Plaster is much harder and usually resists.
- Knock. Drywall sounds hollow between studs. Plaster sounds solid and dense.
- Read the cracks. Diagonal cracks running from the corners of doors and windows are typical of plaster.
Not sure? Send a photo of the damage and the edge of the hole, and we will tell you which it is.
Why plaster cracks, and what the repair involves
Plaster is hard and rigid. When a house moves with settling and seasonal moisture, plaster cracks instead of flexing, and the cracks tend to start at the weak points: door and window corners and where walls meet ceilings. Over decades, the plaster can also lose its grip on the lath behind it. That is when a wall bulges, sounds loose when pressed, or sags on a ceiling.
| Repair method | Typical cost | Used for |
|---|---|---|
| Spackling | $20 to $100 per area | nail holes, hairline cracks, small chips |
| Patching with joint compound and mesh | $70 to $100 per area | larger holes and significant cracks |
| Skim coating | $1 to $3 per sq ft | walls with many cracks or imperfections |
| Replastering | $5 to $10 per sq ft | damaged sections or whole walls |
Method costs are Angi's. Loose plaster has to be reattached or cut back to solid material before any patch goes on, or the crack simply comes back. On a sagging ceiling, that step is the whole job.
Repair plaster or replace it with drywall?
Angi says plaster is almost always worth repairing unless you are already opening walls for a renovation. It lasts a long time, resists mold better than drywall, and suits the character of an older home. On cost, Angi puts replastering at $5 to $10 per square foot against $1.50 to $3 per square foot for new drywall, but tearing out plaster adds demolition, dust and trim work that a local repair avoids.

Frequently asked
How much does plaster wall repair cost in San Jose?
Angi's 2026 averages run from about $50 for a 3-inch hole to $180 for a 48-inch crack, and $1,200 to $1,900 for damage cut back to the lath. Homewyse's calculator for San Jose ZIP 95125 estimates $543 to $656 for a basic wall plaster repair, including a four-hour minimum charge. Tru Service plaster and drywall patching starts from $145, confirmed from photos before any work starts.
Can you patch plaster with drywall compound?
Yes, for many repairs. Angi lists patching with joint compound and mesh at $70 to $100 per area for larger holes and cracks. Loose plaster has to be reattached or cut back to solid material first, or the crack returns.
Is it worth repairing plaster instead of replacing it with drywall?
Usually. Angi says plaster is almost always worth repairing unless walls are being opened for a renovation. Replastering runs $5 to $10 per square foot against $1.50 to $3 for drywall, but a local repair avoids demolition, dust and trim work.
Why do plaster walls crack at door and window corners?
Plaster is rigid, so when a house settles or moves with seasonal moisture it cracks instead of flexing. Door and window corners are the weakest points, so cracks usually start there.
