How much does it cost to plaster or skim a room?

What are typical UK prices for plastering a room?

The table below shows typical market ranges drawn from published UK price guides in 2026. They are not my prices and they are not a quote: they are there so you know whether a figure you have been given is in the normal range.

London and the South East usually sit above these ranges. In the West Midlands, prices tend to fall within them, but the spread between two quotes for the same room can still be wide, for reasons covered below.

What is the difference between skimming and replastering?

Skimming is a thin finishing coat, usually about 2 to 3mm, trowelled over a surface that is already sound: old plaster that is still firmly attached, new plasterboard, or a wall that has been patched. It gives a smooth, flat surface ready to decorate. It is the cheaper option because there is less material and less preparation.

Replastering means taking the old plaster off back to the brick or block, then applying a base coat and a finish coat. It is needed when the old plaster is blown, crumbling, badly cracked or contaminated with salts from past damp. It costs more because of the labour of hacking off, the waste, the extra material and the longer drying time.

A good plasterer will tap the walls before quoting. Hollow-sounding areas tell you whether a skim will hold or whether those patches have to come off first, which is the single biggest reason a skim quote turns into a bigger job. My skimming and plaster repairs pages explain how I decide.

What makes a plastering quote go up or down?

Room size matters less than most people expect. Preparation and access usually decide the price. The things that move a quote most are:

• Condition of the old plaster: blown areas, cracks and holes that need cutting out and filling before any skim.
• Textured finishes: Artex or other textured ceilings need extra preparation, and any testing for asbestos comes first.
• Wallpaper and paint: stripping several layers of paper, or sealing glossy or chalky paint, adds time.
• Ceilings and height: ceilings are slower than walls, and stairwells need platforms or towers.
• Beads and edges: new angle beads on corners and window reveals, and scrim on cracks.
• Protection: a furnished room that has to be emptied, sheeted and masked takes longer than an empty one.
• Waste: hacked-off plaster is heavy, and skip or waste removal is a real cost.
• The plaster itself: lime on an old solid wall costs more than gypsum because it needs more coats, time and skill.

Why do plastering quotes for the same room differ so much?

Usually because the quotes are not for the same job. A low figure can leave out bonding agent or priming, new beads, repairs to blown areas, clearing up or waste removal, and then those come back as extras. A higher figure may include them, or it may include hacking off a wall that one person thought could be skimmed.

Ask each plasterer the same three questions: what preparation is included, which areas (if any) will be hacked off, and is the ceiling in the price. If the answers differ, the prices will too. I set out the preparation line by line in my plastering quotations so you can compare like with like.

Is it cheaper to pay a day rate or a fixed price?

A day rate looks cheaper on paper, but it puts the risk of the job running over on you. If the walls turn out worse than expected, a day rate simply grows. A fixed price for a clearly described job means the plasterer carries that risk, and you know the total before work starts.

Day rates work well for small, open-ended jobs, such as a few patches across a house. For a whole room, most homeowners are better off with a fixed written price that lists what is and is not included.

Does a damp or cold outside wall change the cost?

Yes, and this is where cheap replastering often becomes expensive. If an outside wall has damp patches, salts or blown plaster, the cause has to be found first: gutters, pointing, high ground or condensation on a cold wall. New gypsum on a wall that is still wet tends to fail again. My guide on lime plaster or gypsum explains why lime is often the better choice on old solid walls.

There is also a building regulations point. Under Approved Document L, stripping an external wall back to the brick over more than half of its area counts as renovating it, and the wall may then need to be insulated to a better standard where that is technically and economically feasible. If you are hacking off a cold outside wall anyway, it is the cheapest moment to insulate it. My guide to internal wall insulation cost sets out what that adds.

How long does plastering take, and when can I paint?

Skimming an average room usually takes 1 to 2 days, and the skim needs from several days to a week or more to dry, depending on the weather and ventilation. Full replastering takes longer to apply and can need 2 to 4 weeks before it is fully dry. New plaster turns from dark brown to an even pale pink when it is ready.

Paint it first with a mist coat: watered-down, breathable emulsion that soaks in and gives the next coats something to grip. Vinyl or wipeable paint straight onto new plaster tends to peel. Lime needs breathable paints such as limewash or mineral paint.

What should a written plastering quotation include?

A proper quotation should let you see exactly what you are paying for. Look for:

• which walls and ceilings are included, by room;
• whether each area is a skim or a hack off and replaster;
• preparation: repairs, beads, scrim, priming or bonding;
• the plaster type, gypsum or lime;
• protection of floors and furniture, and daily clearing up;
• waste removal;
• who removes and refits sockets, radiators and skirting if needed;
• how long the job should take, and how long before you can decorate.

If a quote is one line with a total, ask for the detail before you agree to anything.

When should I call a specialist?

Any good plasterer can skim a sound wall. Call someone with building knowledge when the wall itself is the problem: damp or salts on an outside wall, plaster that keeps blowing in the same place, a textured ceiling that may contain asbestos (see the HSE advice and my guide on plastering over Artex), or an old house where lime may be needed.
