How long does it take to decorate a typical living room?

A standard living room (4 x 5 metres) usually takes 4-6 days if it needs full prep work — stripping old paper if there is any, filling holes, sanding, priming, and two coats of paint. If walls are in good condition and you're just repainting, you might be looking at 2-3 days. The time depends heavily on prep. Rushing prep leads to poor finishes, so a decorator who builds in realistic timeframes is usually one who cares about quality. If you're having wallpaper hung, add another 2-3 days depending on pattern complexity and how much stripping is needed first.

Should I stay home while the decorator works?

You don't need to be there every moment, but it helps to be around on the first day to discuss colours, finishes, and any questions. After that, it's up to you. Some people prefer being out (fewer interruptions), others like being home to check progress. Agree this with your decorator beforehand. You'll definitely want to be there when work's finished to check you're happy before they leave. Keep a clear room (all furniture out or heavily covered) and ensure they have access to water and a toilet. These practical things speed things up and keep everyone happy.

What's the difference between matte, satin, and gloss paint?

Matte (or matt) finish has no shine — it hides imperfections well but can be harder to clean and mark more easily. It's good for living rooms and bedrooms where you want a softer look. Satin has a subtle sheen, cleans better than matte, and works well in kitchens and bathrooms where moisture and marks are common. Gloss is shiny and very durable but shows every dust particle and imperfection; it's typically used on woodwork (doors, skirting boards) rather than walls. Your decorator will advise based on the room, but the key is choosing the right finish for the space's use and condition.

What should I do about damp before decorating?

Never decorate over damp. It's a false economy. If you've noticed damp patches, staining, or that distinctive musty smell, get the cause sorted first. Damp can be rising damp (from the ground), penetrating damp (water coming through walls or roof), or condensation (moisture from air). Each needs a different solution. A surveyor or damp specialist can identify it; sometimes it's a simple fix like improved ventilation or a new downpipe, sometimes it's more complex. Most good decorators will refuse to decorate over active damp, and they should — any paint you apply will just peel off once the underlying moisture is dealt with. Sort damp first, then decorate.

Can I negotiate the price if I want a smaller job done?

Yes, but be reasonable. A decorator has fixed costs for turning up, loading equipment, and setting up. A job that takes half a day might only save them a couple of hours compared to a full day. That said, if you're offering regular work (multiple rooms over several weeks, or repeat business), there's room to negotiate. Seasonal pricing also matters — winter is quieter for decorators, so you might get better rates then. Don't try to haggle them down to an unrealistic figure though; remember you get what you pay for, and the cheapest quote often means corners being cut on prep or materials.

What to expect when hiring a decorator in Cardiff

Decorating is one of those jobs that sounds straightforward until you're halfway through and realize you've bitten off more than you can chew. Whether it's interior painting, wallpapering, or preparing surfaces properly, professional decorators bring speed, skill, and the right equipment to do the job well.

In Cardiff, you've got a solid pool of decorators to choose from — from one-man operators who work in their local areas to slightly larger teams. The difference between a rushed job and one that lasts years often comes down to preparation. A good decorator spends time filling holes, sanding surfaces, and protecting your furniture and floors properly. They'll also be honest about what your walls need before they even touch a brush.

This guide walks you through what decorators actually do, what it costs, how to spot someone worth hiring, and the questions you need to ask before you hand over any money. We've kept it practical and based on how the trade actually works — not what the marketing departments want you to think.

What decorating costs in Cardiff in 2026

Decorating prices vary wildly depending on what you're actually asking for. Here's what you're looking at:

Interior painting: A single room (bedroom or lounge) typically costs £400-£800 depending on size, condition of walls, and number of coats needed. A full house interior (3-4 bedrooms, hallway, kitchen, lounge) runs £2,000-£4,500. If walls need significant prep — filling, sanding, treating damp patches — add another 20-40%.

Wallpapering: Hanging wallpaper costs £150-£350 per room on average, but this varies hugely based on pattern complexity and wall condition. Stripping old paper adds £80-£200 per room.

Exterior work: Painting exterior woodwork or rendering costs £40-£60 per hour for labour. A full house exterior typically runs £1,500-£3,500 depending on size and condition.

Preparation work: This is where many quotes differ. Surface prep — filling, sanding, priming — can be 30-50% of the total job cost. Don't hire someone who underestimates this or skips it entirely.

Most decorators charge either by the day (£150-£250) or by the job. Get three quotes and don't automatically pick the cheapest — the middle estimate is often the most realistic. Watch out for quotes that seem too low; they usually mean the decorator is cutting corners on prep or materials.

Materials typically add £200-£600 depending on quality and coverage needed. Budget for good paint or wallpaper — it makes a real difference to the finish.

Accreditations and credentials to look for

Not every decorator holds formal qualifications, but certain credentials do matter when you're hiring.

TrustMark is the main one to look for. It's a government-backed scheme, and TrustMark decorators have been vetted, carry insurance, and are registered with Trading Standards. Finding a TrustMark decorator significantly reduces your risk.

FESPA (the sign and graphics association) and NFDC (National Federation of Decorative & Craft Trades) both have member directories. These aren't mandatory, but members commit to standards and customer service expectations. If a decorator is a member, they'll usually mention it.

Insurance matters more than you'd think. Your decorator should carry public liability insurance (minimum £1 million) in case they damage your property or injure themselves. They should also have employer's liability if they have staff. Always ask to see certificates — don't just take their word for it.

Certifications in specific areas (asbestos awareness, lead paint handling, damp treatment) show a decorator takes health and safety seriously, especially in older Cardiff properties where these risks are genuine.

Many good decorators have no formal qualifications but years of practical experience and happy customers. What matters more than a certificate on the wall is whether they're insured, whether they do proper prep work, and whether previous customers will back them up. Check online reviews but remember that unhappy customers are often louder than satisfied ones.

Decorating in Cardiff: what's different here

Cardiff's housing stock is mixed — Victorian terraces in areas like Canton and Cathays, 1960s-70s semis in the suburbs, and newer estates in places like St Mellons. This matters because different house types need different approaches.

Victorian terraces commonly have high ceilings, original plasterwork, and — if they've been poorly maintained — damp issues. Decorators working on these properties need to understand lime mortar, breathable paints, and when NOT to use modern moisture barriers that trap water in walls. Badly applied modern paint on old lime plaster is a recipe for peeling paint and hidden damp problems.

The Welsh climate is wet. Cardiff gets significant rainfall, which affects how long exterior work lasts and why proper surface prep and priming are crucial. A decorator who understands how moisture moves through different wall types and materials will save you money long-term.

Many Cardiff properties also have solid stone or brick walls rather than cavity construction, which affects damp treatments and paint choices. Some areas, particularly near the city centre and docks, have properties with older lead paint. If you're renovating a property built before 1980, mention this to your decorator — they should know safe practices.

Local decorators in Cardiff tend to know the housing stock well. They understand which paints work on local stone, which areas are prone to damp, and which builders left the worst surfaces. That local knowledge is worth paying for — it often prevents expensive mistakes down the line.

How to find and hire a reliable decorator

Start by getting recommendations from friends, family, or local Facebook groups — word of mouth is still the best filter for tradespeople. If someone you know used a decorator and was genuinely happy (not just 'okay'), that's a solid starting point.

Search TrustMark's directory online for accredited decorators in your postcode. It takes minutes and significantly narrows down your options to vetted, insured traders.

Once you've got a shortlist of 3-5 decorators, contact them with clear details: what rooms you want decorated, their current condition, what finish you want (matte, satin, gloss), and roughly when you'd like work done. Ask them to visit for a quote rather than quoting over the phone — they need to see walls, existing finishes, and any problem areas.

When they visit, watch how they assess the space. Good decorators will ask questions: How old is the paint? Has this room been damp? What's underneath? They'll point out what prep work is needed and why. If someone walks in, glances around, and gives a quote in five minutes, they're probably underestimating the work.

Get written quotes from at least three decorators. A proper quote should list: the work being done, materials included or excluded, start and finish dates, and payment terms. Clarify whether they provide materials or if you're buying them.

Check references — ask for contact details of recent customers (not just 'happy customers' but actual people you can ring). Most good decorators have no problem with this.

Once you've chosen someone, agree everything in writing: scope of work, costs, timeline, and what happens if things change. Pay a deposit (typically 25-33%) only once you've got a written agreement.

Eight questions to ask before hiring

Before you commit, ask these questions:

1. Are you TrustMark accredited and insured? Get insurance certificates and verify them. This is non-negotiable.

2. What prep work do you think this room needs? Listen for specifics: Are they mentioning filling, sanding, priming? Or are they vague? Good decorators talk through prep in detail.

3. Do you supply materials or should I buy them? Get clarity on who's providing paint, wallpaper, undercoat, fillers, etc. If they supply it, what brands do they use? If you're buying, do they have recommendations?

4. How long will this take? Get realistic timescales per room. A well-prepped bedroom typically takes 3-5 days. If someone says 'a couple of days,' they're probably skipping prep.

5. What happens if I want changes mid-project? Ask how you'll handle extras or changes to the scope. Will they charge extra? How much notice do you need to give?

6. Can you provide references from recent customers? Ask for people with similar work done in the last year. Actually ring them — it takes ten minutes and is worth it.

7. What's your cancellation and refund policy? What happens if you change your mind before work starts? What if they abandon the job halfway through?

8. Do you have experience with properties like mine? If you've got a Victorian terrace or period features, ask if they've worked on similar properties. Experience with your house type matters.
