How much does it cost to replaster a house?
Replastering is priced by the area of wall and ceiling to skim. Enter the area below for a live, region-adjusted estimate, then build it into a full schedule of works.
What drives replastering cost
- 1Measure the area
Add wall areas (length × height) and ceilings. A room is usually ~2.6× its floor area in wall+ceiling.
- 2Skim vs board-and-skim
Skimming a sound wall is cheapest; walls in poor condition need overboarding first, which costs more per m².
- 3Access and prep
Removing old plaster, protecting floors and making good add labour beyond the skim rate.
Plastering quotes vary widely, so knowing the material side helps you judge a price: a 25 kg bag of Multi-Finish covers about 10 m², so materials are a small part of the job — the rest is skilled labour. This calculator separates the two so you can see where the money goes.
Replastering costs by job (indicative)

| Whole 3-bed house (skim) | ~300 m² | £4,500 – £8,000 |
| Ceiling only | ~12 m² | £180 – £300 |
| Board & skim (poor walls) | per m² | £28 – £60/m² |
Skim onto sound backgrounds; boarding out or two-coat work costs more. Indicative — confirm with quotes.
