How Much Does It Cost to Plaster a Room?

The cost to plaster a room in the UK typically depends on size, condition and how much preparation is needed. A small room with sound walls might need only a re-skim, while a larger room with damaged plaster, high ceilings or old plaster to remove costs considerably more. There is no single price that fits every room — which is why an accurate quote needs the room dimensions and a few photos.

What affects the price

• Room size — bigger walls and ceilings mean more materials and labour
• Condition of existing surfaces — sound plaster needs a re-skim; blown or damaged plaster needs removal and a full re-plaster
• Preparation — stripping wallpaper, removing old plaster, or making good all adds time
• Number of coats — a re-skim is one coat; a full re-plaster is a backing coat plus a skim
• Ceiling height — high ceilings (common in period London properties) take longer and need access equipment
• Access — tight stairwells, upper floors, or furniture to work around
• Materials — standard gypsum vs lime plaster for older properties
• Location — London labour rates are higher than much of the UK

Re-skim vs full re-plaster

The biggest price driver is whether the room needs a re-skim (a thin new finish coat over sound existing plaster or plasterboard) or a full re-plaster (removing old plaster, applying a backing coat, then skimming). A re-skim is far less work. See our skimming cost page for skimming-specific pricing.

Typical cost ranges

These are indicative ranges for a standard room in reasonable condition. Actual prices vary — use them as a rough guide, not a quote.

| Room | Typical work | Indicative range | |---|---|---| | Small room (re-skim, walls) | Re-skim walls only | Lower end | | Medium room (re-skim) | Re-skim walls + ceiling | Mid range | | Large room (full re-plaster) | Remove + re-plaster walls + ceiling | Higher end | | Ceiling only | Re-skim or overboard + skim ceiling | See ceiling plastering cost |

Labour and materials

A plasterer's cost is mainly labour. Materials (plaster, bonding, beads, scrim) are a smaller part of the bill. Plasterer day rates vary — see our plasterer day rates page for how day rates work and what influences them. Most small-to-medium rooms are quoted as a fixed price rather than a day rate.

How to get an accurate quote

The most reliable way to price a room is to have a plasterer see it — or at least see photos. To get a useful quote:

1. Measure the room (wall lengths and ceiling height)
2. Note the condition — is the existing plaster sound, cracked, or blown?
3. Say whether you want walls only, ceiling only, or both
4. Send a few photos of the walls and ceiling
5. Mention anything unusual — artex ceilings, damp, recent leaks

Why quotes vary

Two plasterers can quote very different prices for the same room because they're planning different amounts of preparation. A cheap quote may assume a quick re-skim over a surface that really needs old plaster removed. A thorough quote includes the preparation the job actually needs — which is why the cheapest quote isn't always the one that lasts.

FAQ

How much does it cost to plaster a room? It depends on size, condition and preparation. A re-skim of a small room costs far less than a full re-plaster of a large room with damaged walls.

Is it cheaper to re-skim or re-plaster? Re-skimming is cheaper because it's a thin finish coat over a sound surface. Full re-plastering involves removal and a backing coat, so it costs more.

How do I get an accurate price for my room? Send the room dimensions and a few photos of the walls and ceiling. A plasterer can then quote based on the actual condition, not a guess.

Do plasterers charge per day or per room? Both. Small and medium rooms are usually a fixed price; larger or open-ended jobs may be day-rated.

Why do quotes vary so much? Because they include different amounts of preparation. The lowest quote may skip work the room actually needs.
