Replastering in Ireland costs roughly €15–€25 per m² for a skim coat and more for a full re-plaster, with a single room typically €500–€1,500 and a whole 3-bed house around €3,000–€8,000 (indicative 2026 ranges). The exact figure depends on wall condition, ceiling height, and how much preparation is needed.
Skim vs full re-plaster
The two jobs are very different in price and scope.
A skim coat is a thin 2–3mm layer of finishing plaster applied over walls that are already sound — existing plaster in good condition, or fresh plasterboard. It gives a smooth, paint-ready surface and is the cheaper option.
A full re-plaster means hacking off failed plaster back to the block or brick, applying a base “scratch” coat, then a float coat, then the skim. You need it where walls are damp, cracked, blown (hollow-sounding), or where old lime plaster has perished. It uses more material and labour, so it costs considerably more per m².
Replastering cost table
| Job | Indicative 2026 range |
|---|---|
| Skim coat (per m²) | €15–€25 |
| Full re-plaster (per m²) | €25–€45 |
| Small room (skim) | €400–€900 |
| Average room (full re-plaster) | €800–€1,800 |
| Plaster one ceiling | €300–€700 |
| Whole 3-bed house | €3,000–€8,000 |
These are indicative 2026 ranges only. Plastering is priced by area and condition, so always get at least three written quotes after a plasterer has seen the walls.
What affects the price
- Skim vs full re-plaster — the single biggest driver. Hacking off and building up base coats can double the per-m² rate.
- Wall area and ceiling height — high ceilings need scaffolding or hop-ups and slow the work.
- Condition and prep — removing old wallpaper, treating damp, or re-bonding loose plaster all add cost before plastering even starts.
- Bonding agents and beading — fresh corners, window reveals, and metal angle beads add time and materials.
- Access and location — upstairs rooms, awkward stairwells, and rural callouts can nudge prices up.
- Drying and decoration — fresh plaster needs days to dry before painting; a mist coat and finish are usually a separate decorating cost.
Ways to save
- Bundle rooms together. A plasterer on site for a full house works more efficiently than for one-off rooms, lowering the effective per-m² rate.
- Do the prep yourself. Stripping wallpaper, clearing rooms, and lifting fittings can shave labour hours.
- Only re-plaster what needs it. Sound walls often just need a skim, not a full strip-back. A good plasterer will tell you which is which.
- Time it with other works. If you are dot-and-dabbing plasterboard as part of internal wall insulation, the skim can be done in the same pass.
There are no grants for cosmetic plastering itself. However, if plastering is part of a wider energy upgrade — for example re-finishing walls after dry-lining — the insulation element may attract SEAI insulation grants. Replastering is usually one line in a bigger project, so it is worth reading our full house renovation cost guide to see where it sits in the budget.
Plaster and energy upgrades
Replastering is often the moment to improve a wall’s performance. If you are dry-lining for warmth, the new plasterboard and skim are part of that insulation job rather than a standalone cost. Likewise, fresh plaster is the ideal base before interior painting, so sequencing the two together avoids paying twice for prep and decoration. If your walls are damp or cold, fixing the underlying cause — rather than just re-skimming over it — protects your BER rating and stops the problem returning.
FAQ
See the questions above for typical room and whole-house costs and the skim-versus-full-plaster distinction. The headline point: most homes need a skim, not a full strip-back, so an honest assessment of wall condition is the best way to keep the bill down.
