How much does it cost to skim a ceiling?
Skimming a ceiling is priced by area, with overboarding if the old ceiling is poor. Enter the ceiling area below.
What skimming a ceiling involves
- 1Assess the ceiling
A sound ceiling can be skimmed directly; a cracked, artexed or lath-and-plaster ceiling is usually overboarded first.
- 2Skim coat
A thin plaster finish coat is applied and trowelled flat for a paint-ready surface.
- 3Dry and paint
Fresh plaster dries in a few days to an even pale colour, then it's misted and painted.
A crisp, flat white ceiling quietly lifts a whole room, while a cracked or artexed one drags it down. Skimming is cheap per m²; the decision that moves the cost is whether to overboard first — and on tired ceilings, it usually pays to.
Ceiling skim costs (indicative)
| Job | Basis | Indicative cost |
|---|---|---|
| Skim over sound ceiling | per m² | £15 – £30/m² |
| Overboard + skim | per m² | £25 – £45/m² |
| One room (~12 m²) | skim | £180 – £360 |
| Whole 3-bed house ceilings | ~90 m² | £1,400 – £3,000 |
Overboarding is common where ceilings are cracked, artexed or old lath-and-plaster. Confirm with quotes.
Frequently asked questions
How much does it cost to skim a ceiling?+
Skimming a sound ceiling costs £15–£30 per m², so a room ceiling (~12 m²) is roughly £180–£360. Overboarding first (for cracked, artexed or lath ceilings) costs £25–£45 per m².
Should I overboard or skim a ceiling?+
If the ceiling is sound and flat, skim it directly. If it's cracked, sagging, artexed or old lath-and-plaster, overboarding gives a stronger, flatter, safer result — worth the extra per m².
