Step by step

What's Involved in Hiring a Plastering

Plastering is one of those trades where the skill of the tradesperson makes all the difference — a good plasterer leaves walls perfectly smooth and ready for painting with minimal sanding.

1

Assess your walls or ceilings

Work out what needs doing — is the existing plaster crumbling, bulging, or just tired-looking? Tap the walls to check for hollow spots where plaster has come away from the brick. If it is just cosmetic, a skim coat may be enough. If the plaster is failing, a full replaster is needed.

2

Get quotes from plasterers

Invite two or three plasterers to look at the job. A good plasterer will tell you honestly whether you need a full replaster or just a skim. Ask for a fixed price per room rather than a daily rate. Check reviews and ask to see photos of previous work — the quality difference between plasterers is huge.

3

Prepare the room

Move all furniture to the centre of the room or out completely. The plasterer will cover everything with dust sheets, but plaster dust gets everywhere. Remove curtains, blinds, and anything hanging on the walls. The plasterer needs clear access to every wall and a water supply nearby.

4

Old plaster is removed if needed

For a full replaster, the old plaster is hacked off back to bare brick or block. This is the messiest stage and generates a lot of rubble. For a skim coat, the existing surface is prepared with PVA or a bonding agent to help the new plaster stick.

5

New plaster is applied

The plasterer applies the plaster in thin layers, building up to a smooth finish. A full replaster involves a scratch coat, then a finishing coat. A skim is typically two thin coats applied wet-on-wet. The plasterer works quickly as plaster sets fast — this is where experience really counts.

6

Drying and aftercare

Fresh plaster needs 2-6 weeks to fully dry before painting, depending on ventilation and temperature. Do not use a heater to speed this up as it causes cracking. The first coat of paint must always be a mist coat (watered-down emulsion) to seal the new plaster properly.

Local insights

What Affects Plasterer Costs in Barnet?

Barnet's housing stock ranges from Georgian and Victorian terraces to post-war estates and modern new-builds, with a range of property types and ages that can affect the scope and cost of work across the borough. Properties in areas like Islington, Hackney and Brixton vary enormously in age, layout and condition, all of which directly affect plasterer costs. With a population of null, Barnet is one of the more expensive areas for plasterer work in the UK. Older properties tend to need more preparation work and present access challenges that push prices toward the higher end — for example, plaster a ceiling here averages around £500.

London is the most expensive part of the UK for trade work, with labour rates running around 24% above the national average. This reflects the high cost of living, congestion charges, and expensive parking that tradespeople factor into their quotes. In Barnet, local demand for plasterer services varies depending on the mix of residential and commercial properties in the area, and there is no shortage of qualified plasterer professionals across the capital. With fewer tradespeople based locally, you may find slightly less choice, and it is worth booking ahead for larger jobs. Prices still vary by 30-50% between tradespeople for the same job, making multiple quotes essential.

Several factors affect what you will pay for plasterer work in Barnet. The scope and complexity of the job is the biggest driver — straightforward work in accessible locations will be at the lower end, while anything involving older properties, difficult access, or structural complications will cost more. Material choices also make a significant difference; opting for premium brands or higher-spec products can add 20-40% to the total. As one of the more expensive areas for trade work, Barnet residents typically pay around £810 for plaster a room (walls) and £3,110 to £8,710 for k-rend exterior finish.

When getting quotes in Barnet, aim for at least three from different qualified professionals. With fewer tradespeople based locally, you may find slightly less choice, and it is worth booking ahead for larger jobs. Ask each one to visit and assess the work in person rather than quoting over the phone. A good plasterer will check the existing setup, identify any potential complications, and give you a detailed breakdown of costs. In a area like Barnet, there is plenty of choice, so do not settle for the first quote you receive. Be wary of quotes that seem significantly cheaper than others — they may be cutting corners on materials or not including everything in the price. Always check qualifications, insurance and recent reviews before hiring.

Depending on the work involved, you may also need painting & decorating (£250–£810), builder (£37,320–£99,520), or damp proofing (£310–£1,245) in Barnet.

Common questions

Frequently Asked Questions

Common questions about plasterer costs in Barnet.

What is the difference between plastering and skimming?
Plastering typically refers to applying a full coat of plaster (undercoat and finish coat) to bare brickwork or new plasterboard. Skimming is applying just a thin finish coat over existing plasterboard or old plaster to create a smooth surface. Skimming is quicker and cheaper since only one coat is needed.
How long does plaster take to dry before I can paint?
New plaster typically takes 2-6 weeks to fully dry depending on room ventilation, temperature and humidity. You can tell it is ready when it turns a uniform light pink or white colour with no dark patches. Painting too soon traps moisture and causes the paint to peel. The first coat should always be a mist coat (diluted emulsion).
Should I replaster or use plasterboard?
Dot-and-dab plasterboard is quicker, cheaper and ideal for covering rough or uneven walls. Re-plastering gives a thinner, more traditional finish and does not reduce room size. For very uneven walls, plasterboard is usually the better option. For small patch repairs, re-plastering the affected area is more practical.
What is rendering and how is it different from plastering?
Rendering is the external equivalent of plastering — it is a cement-based coat applied to outside walls for protection and appearance. Interior plastering uses gypsum-based plaster which is not waterproof. Render can be smooth, textured, or coloured, and modern monocouche (through-colour) renders do not need painting.
How much does a plasterer charge per room?
A skim coat on a standard room costs £300-£650. A full replaster (stripping old plaster and applying new) costs £400-£1,000 per room. Ceilings are quoted separately and cost £250-£650 each. Prices vary by region — London and the South East are typically 20-30% higher than the Midlands or North.
Can I plaster over old wallpaper?
No. Wallpaper must always be stripped before plastering. Plaster will not bond properly to wallpaper and will crack and fall off. The walls need to be stripped back to a clean, stable surface. If the plaster underneath the wallpaper is in good condition, a skim coat over the top is sufficient.
How do I know if my plaster needs replacing?
Signs that plaster needs replacing include large cracks that keep reappearing after filling, hollow-sounding patches when you tap the wall, damp staining or salt deposits coming through, and plaster that crumbles when touched. Small cracks and minor damage can usually be patched without replastering the whole wall.
What is K-Rend and is it worth the extra cost?
K-Rend is a brand of silicone render that comes in a range of colours mixed into the product itself, so it never needs painting. It is breathable, water-repellent, and low-maintenance. It costs more than traditional sand and cement render, but you save on repainting every 5-10 years. For a typical semi-detached house, K-Rend costs £4,500-£7,000 compared to £2,500-£4,500 for traditional render.
How messy is plastering?
Very. Plastering is one of the messiest trades. Expect plaster dust on every surface in the room, splashes on floors, and dust spreading into adjacent rooms through doorways. A good plasterer will lay dust sheets and cover furniture, but you should remove anything valuable or delicate from the room. Plaster washes off hard floors easily but is harder to remove from carpets.
How much does a plasterer cost in Barnet in 2026?
Plaster a Room (Walls) in Barnet typically costs between £500 and £1,245, with the average being around £810. Prices vary depending on the scope of work, materials used, and the specific requirements of your property.
Are plasterer prices cheaper in Barnet than London?
Barnet prices are 24% above the national average, though still comparable to London for plaster a room (walls).
How do I find a good plasterer in Barnet?
Get at least three quotes from different tradespeople, check recent reviews, and ask whether the quote includes VAT and everything you need. A detailed written quote that breaks down all costs is a good sign. Always check qualifications, insurance and recent reviews before hiring.
What affects plasterer prices in Barnet?
The main factors are the scope and complexity of what you need, the options and products chosen, and local market rates. Barnet rates are 24% above the national average. Getting multiple quotes is the best way to ensure a fair price.
Do plasterer prices include materials in Barnet?
The prices shown on this page include all typical costs. However, when getting real quotes, always confirm what is and isn't included. Some tradespeople break out costs separately, while others give an all-in price. Ask for a detailed breakdown before agreeing to any work.
