How long does plastering a room take?

It depends on room size and the job type. A simple skim coat on a medium bedroom takes 1-2 days. Plastering from scratch (applying base coats and finish) on new stud walls takes 2-3 days for an average room, plus drying time. Between coats, you need 24-48 hours for the plaster to firm up. The plasterer won't apply the next coat until the previous one is touch-dry. Don't expect them to rush — poor timing causes cracking and failure. For larger areas or difficult surfaces, add extra days. Always ask for a realistic timeline and be prepared for weather delays (very cold or damp conditions slow drying).

Can you plaster over old damaged plaster?

Not directly. Loose, crumbly, or blown plaster (where the base has separated from the wall) needs removing first. If you plaster over it, the new coat will eventually fail and crack. A good plasterer will test the surface with a hammer or by tapping — hollow areas show where plaster isn't bonded. They'll remove the loose bits, clean back to a solid base, prime it (usually with PVA), and then plaster. This adds time and cost, but it's essential. In some old Wrexham properties with extensive damage, it's sometimes cheaper to plasterboard over the mess than repair traditional plaster wall by wall.

What's the difference between a plasterer and a drywall fitter?

A plasterer works with wet plaster (gypsum or lime mortar) and applies it to walls and ceilings, skimming, coating, and finishing by hand. A drywall fitter (or plasterboarder) hangs plasterboard sheets, tapes joints, and fills gaps — but they don't apply wet plaster. Many tradespeople do both, but ask if you're not sure. For traditional lime plaster work in older Wrexham homes, you specifically need a plasterer with lime experience. For new builds with board and finish, either might work, but plasterers typically handle the finishing coat. Know what you're asking them to do before booking.

Should I stay home while the plasterer works?

You don't need to hover, but it's useful to be around for the first hour to discuss site access, water, power, and to clarify any details about the walls. After that, they'll work faster without an audience. Do check in daily — not to supervise, but to spot any issues early. If the plaster looks wrong (very rough, uneven, or cracking before it's dried), you can discuss it while they're still on-site rather than discovering problems after they've left. During drying time between coats, keep the room reasonably ventilated and avoid draughts (which cause uneven drying and cracking). Don't use the room until plaster is fully cured — usually 2-3 weeks before decorating.

How much does it cost to fix cracks in old plaster?

Small hairline cracks (less than 2mm) can often be filled with flexible filler by a decorator, costing £30-£80 depending on how many you have. Larger cracks (3-5mm) need raking out (removing loose material from the crack) and filling with plaster or filler — typically £100-£250 depending on how many and how long they are. If cracks are widespread or caused by damp or structural movement, you need a surveyor first to diagnose the cause. A plasterer won't just plaster over a structural problem. Very old Wrexham properties sometimes have harmless settlement cracks; others indicate ongoing issues. Get professional advice before paying for cosmetic fixes that won't last.

What plasterers do and why you might need one

Plastering isn't just about making walls look smooth. A good plasterer prepares surfaces, applies base coats (scratch coat, float coat) and finishing plaster to give you a surface you can paint or paper. You'll need one if you're renovating, fixing damp damage, replacing old lath and plaster, or finishing new stud walls.

In Wrexham, many older terraced and semi-detached homes have traditional lime mortar plaster, which needs understanding and care. Newer builds need modern gypsum plaster. A plasterer knows the difference and won't ruin your walls by using the wrong material.

They also handle skimming (a thin finishing coat over existing plaster), coving, and patch repairs. It's skilled work — poor application leads to cracking, uneven surfaces, and costly redecoration later.

What plasterers charge in Wrexham

Costs vary by job type and complexity. Here's what you'll typically pay in 2026:

Skim coating a room: £250-£450 per room (depending on size and existing surface condition).

New plaster on stud walls: £12-£18 per square metre for a two-coat application.

Patch repairs and small areas: £80-£200 depending on size and difficulty.

Coving installation: £8-£15 per metre, plus materials.

Lime plaster (traditional work): £15-£22 per square metre — more expensive than modern gypsum because it takes longer and requires specialist knowledge.

Most plasterers charge either by the hour (£25-£40) or by the square metre. Get at least three quotes. Don't pick the cheapest — a plasterer rushing through will leave you with poor-quality walls. Factor in 2-3 days drying time between coats, so budget for that timeline too.

Qualifications and standards to look for

Check your plasterer holds relevant qualifications:

City & Guilds Level 2 or 3 in Plastering — the industry standard. Shows they've trained formally and can handle internal and external work, fibrous plaster, and specialist techniques.

TrustMark registration — a government-backed scheme. TrustMark plasterers meet trading standards, have public liability insurance, and follow a code of conduct. You get consumer protection if things go wrong.

CITB certification — Construction Industry Training Board. Proves ongoing professional development and safety knowledge.

Always ask to see certificates. A reputable plasterer won't mind. Check their liability insurance is current — minimum £1 million is standard. If they're working on listed buildings or heritage properties in Wrexham's conservation areas, ask if they have experience with period-appropriate materials like lime mortar.

Don't assume no qualifications means no skill, but formal training reduces risk.

Wrexham housing and plaster-specific issues

Wrexham's housing stock is a mix of Victorian and Edwardian terraces, 1960s semis, and newer developments. This matters for plastering.

Older properties often have lime mortar plaster and potentially damp issues — particularly rising damp in ground-floor rooms. Applying modern gypsum plaster over damp walls is pointless; it'll fail. A good local plasterer will spot damp, recommend fixing it first (usually with a surveyor and specialist), then plaster over it correctly.

Many Wrexham homes have lath and plaster ceilings and walls. These are brittle and need careful handling. Patching without removing surrounding loose material just delays the problem. Experienced plasterers here know how to assess what can be saved and what needs replacing.

Newer builds around the edges of town often have plasterboard over timber frames. These dry faster but need correct finishing techniques to avoid cracks at joints.

Check if your property is in a conservation area — parts of central Wrexham are. Listed buildings and conservation areas sometimes require lime mortar, not cement-based. Ask your plasterer upfront if they work with period materials and methods.

Finding and hiring a plasterer step by step

Start by asking local builders, renovation forums, or neighbours who's done good work. Word of mouth is reliable.

Use directories like Best Trades Wales to find plasterers near you. Check reviews (look for specific detail, not just 'great job'), and verify TrustMark or City & Guilds badges on their profile.

Contact at least three. Don't email a question that needs a phone call — chat to them. You'll learn more about their approach. Ask:

Have they worked on similar properties to yours?
Can they provide references from recent local jobs?
What's their timeline and will they need site access (parking, water, electricity)?
Do they handle all prep work (removal of old plaster, cleaning, priming)?

Get written quotes with scope of work clearly listed. Quotes should detail:

Square meterage or rooms covered
Number of coats
Materials included or supplied separately
Start and end dates
Payment terms

Don't book on a handshake. A contract protects both of you. Agree on payment — 50% upfront, 50% on completion is standard, though some take staged payments for longer jobs.

Ask for proof of insurance before work starts.

Key questions to ask before booking

Get these answers before you commit:

"Have you worked on properties like mine?" Lime plaster, lath and plaster, modern gypsum — different properties need different experience.

"What prep work do you do?" Will they remove loose plaster, PVA prime walls, repair cracks? Don't assume it's included.

"How long between coats and to final finish?" Plaster needs time to dry. They should explain drying times and not rush it.

"What happens if cracks appear after you've finished?" A reputable plasterer offers a warranty, typically 12 months on workmanship.

"Who supplies materials?" Some plasterers include it in the quote, others expect you to buy. Clarify.

"What's the payment schedule?" Agree upfront. Paying everything upfront is risky; paying nothing until the end leaves them short. Split payment is fairest.

"Are you TrustMark registered or City & Guilds qualified?" They'll have certificates to show.

"Do you have references I can contact?" Ask for at least two recent local jobs.

Trust your gut. A professional plasterer explains things clearly, doesn't pressure you, and is happy to answer questions.
