How Much Does It Cost to Skim a 3-Bedroom House in London? (2026 Prices)

To skim a 3-bedroom house in London in 2026 you should budget between £2,500 and £5,000. That covers skimming every wall and ceiling — typically 3 bedrooms, a living room, hallway and landing, kitchen and bathroom — using British Gypsum Thistle MultiFinish over sound existing plaster. If your walls need a backing coat first (bare brick or badly blown plaster), expect £3,500–£6,500.

Below is the full breakdown: price per square metre, room-by-room costs, the materials you're paying for, what pushes the price up, and how long it takes.

Skimming Prices Per Square Metre (2026)

| Surface | Price per m² | Notes | |---------|-------------|-------| | Wall skimming | £15–£25/m² | 2mm MultiFinish over sound plaster or board | | Ceiling skimming | £18–£35/m² | Overhead work — slower and more physically demanding | | Full re-plaster (bonding + skim) | £25–£45/m² | Needed for bare brick or badly damaged walls | | Ceiling overboard + skim | £30–£45/m² | Old lath/artex ceilings we board over first |

Room-by-Room Cost for a 3-Bed London House

| Room | Typical cost | Time on site | |------|-------------|--------------| | Living room (4x4m) | £600–£900 | 1 day | | Master bedroom (4x3.5m) | £450–£700 | 1 day | | Bedroom 2 (3x3m) | £350–£550 | ½–1 day | | Bedroom 3 / box room (2.5x2.5m) | £250–£400 | ½ day | | Hallway + landing + stairs | £500–£800 | 1 day (awkward access) | | Kitchen (walls only, units in) | £200–£400 | ½ day | | Bathroom (water-resistant board + skim) | £300–£500 | ½ day | | Whole house total | £2,500–£5,000 | 4–6 working days |

What You're Actually Paying For — Materials Breakdown

A 3-bed skim typically uses around 40–60 bags of plaster. Here's what goes into the quote:

• Thistle MultiFinish — ~£8/bag, 30–50 bags needed
• Thistle Bonding Coat (where walls need backing) — ~£9/bag
• Knauf plasterboard (for ceilings we overboard) — £6–£10 per board
• Scrim tape & stainless angle beads — £2–£5 each
• PVA bonding agent — £15–£25 per 5L
• Labour — £300–£450/day per plasterer in London (usually a 2-man team)

Materials alone run £400–£700 for a full house; the rest is labour, setup, prep and clean-up.

What Pushes the Price Up

1. Ceilings — overhead work is slower and priced higher than walls
2. High rooms & stairwells — need tower scaffolding, adds £150–£300
3. Removing old plaster — hacking off blown plaster adds £8–£15/m²
4. Artex ceilings — must be sealed and skim-tested first; asbestos risk pre-2000
5. Wallpaper or woodchip — stripping adds labour before we can skim
6. Damp or water damage — must fix the cause first, then re-plaster
7. Access — parking restrictions, upper-floor only, no lift all add time

Skim vs Re-Plaster vs Overboard — Which Do You Need?

| Option | When it's right | Cost | |--------|----------------|------| | Skim only | Existing plaster is sound, just needs a smooth finish | £15–£25/m² | | Re-plaster (bonding + skim) | Bare brick, blown plaster, or very uneven walls | £25–£45/m² | | Overboard + skim | Old lath/plaster or artex ceiling that's cracked but sound | £30–£45/m² | | Full strip + reboard | Extensively damaged, multiple layers, or damp history | £40–£60/m² |

How Long Does Skimming a 3-Bed House Take?

• On-site work: 4–6 working days for a 2-plasterer team
• Drying time: 2–4 weeks before you can paint (plaster turns pale pink when dry)
• Don't paint early — sealing in moisture causes crazing and paint peeling

How to Keep the Cost Down

• Combine rooms into one booking — setup costs are spread across the whole job
• Clear the rooms and take up carpets yourself before we arrive
• Leave sound plaster in place — only strip what's actually blown
• Avoid peak summer (June–August) when London plasterers are busiest
• Get a fixed quote, not a day rate, for anything over two rooms

Common Mistakes to Avoid

• Skimming over blown plaster — it will sound hollow and crack within months. Always tap-test and cut out hollow areas first.
• Skipping PVA on old plaster — the high suction pulls moisture out too fast and the skim peels.
• Painting too soon — wait until the plaster is uniformly pale pink, not patchy.
• One coat on ceilings — ceilings need two thin coats, not one thick one, or hairline cracks appear.

FAQs

How much to skim a 3-bed house in London? Between £2,500 and £5,000 in 2026, depending on ceiling height, access and whether any walls need a backing coat first.

Is it cheaper to reboard or re-plaster? Skimming over sound plaster is cheapest. If walls are badly damaged, dot-and-dab new board then skim is often more cost-effective than hacking everything off.

How long before I can paint new plaster? 2–4 weeks. The plaster changes from dark pink to pale pink as it dries — only paint when it's an even pale colour.

Do I need to remove artex before skimming? Not always — artex can be skimmed over if it's sound and asbestos-free. Pre-2000 artex should be tested for asbestos first. We arrange the test.

Will skimming add value to my house? Fresh, smooth plaster is one of the most cost-effective pre-sale improvements. Buyers notice cracked and textured walls immediately.
