What changes a plastering price
- the size of the room and the ceiling height
- new work or repairs to existing walls
- the number of coats and the finish level
- ceilings, cornices and detail work
- access and how much needs to be protected
Ask what the quote covers
Ask whether the price includes setting, sanding, cleanup and a final coat ready for paint. Compare quotes line by line, as in our guide on comparing tradie quotes.
