  • Many projects fall around $70 per m² for standard repairs.

Typical Price by Repair Type

Small Repairs (Cracks, Minor Holes)

  • Around $50–$200 per job or at the lower end of per-m² pricing.

Wall Plaster Repairs

  • Roughly $25–$90 per m² depending on finish and condition.

Ceiling Repairs

  • Often higher due to labour difficulty, commonly $300–$1,000 per job.

Extensive or Heritage Repairs

  • Can exceed $250 per m² for intricate or decorative plasterwork.

Factors That Affect Plaster Repair Cost

Several variables influence your final quote:

  • Extent of damage — water damage or structural cracks cost more

  • Location of repair — ceilings are pricier than walls

  • Access and prep work — removing old plaster or scaffolding adds labour

  • Finish level — skim coats and paint prep increase costs

  • Type of plaster — hard plaster vs wet plaster

Larger or complex jobs may also be quoted as a fixed price rather than per square metre.
