How long should a professional paint job last?
A professional interior repaint should last 5–10 years. If your paintwork is peeling, flaking or marking within a year or two, that's not normal wear. It's a sign the job was rushed. Here's what "lasting" really looks like.
Realistic lifespans by area
| Area / surface | Typical lifespan |
|---|---|
| Bedrooms & living rooms | 7–10 years |
| Hallways, stairs & landings | 4–6 years |
| Kitchens & bathrooms | 4–7 years |
| Ceilings | 8–12 years |
| Woodwork (doors, skirting, trim) | 5–8 years |
High-traffic and high-moisture areas naturally need refreshing sooner. A quiet spare bedroom can look great for a decade; a busy family hallway takes far more punishment. Homes with young children, pets or a lot of coming and going will always mark up faster, which is where a durable, wipeable finish earns its money.
What shortens a paint job's life?
If paintwork fails early, it's almost never bad luck. It's usually one of these:
- Thin or skipped preparation: painting over dust, grease, flaking paint or unfilled cracks means poor adhesion and early peeling.
- Too few coats: one thin coat looks patchy and wears through quickly; two proper coats of trade paint last far longer.
- Economy paint: cheap emulsions scuff, mark and fade sooner than durable trade products.
- Damp and moisture: untreated damp, condensation and poor ventilation lift and blister paint from behind.
- Wrong finish for the room: a delicate matt in a busy hallway will mark far sooner than a durable one.
- Painting over a problem: covering stains, mould or previous failures without fixing the cause just delays the same issue.
What actually makes paint last
- Preparation: up to 80% of a lasting finish. Filling, caulking, sanding and priming give paint a sound surface to grip.
- The right number of coats: two coats of quality trade paint, not one thin one.
- Quality paint: durable trade emulsions resist scuffs, marks and fading far better than economy paint.
- The right finish for the room: durable/wipeable finishes in busy areas.
- Fixing the cause: treating damp, stains or flaking before painting over them.
Signs your paintwork needs redoing
Not sure whether it's time? These are the usual tell-tale signs a room is due a refresh:
- Scuffs and marks that no longer wipe clean, especially around light switches and doorways
- Patchy sheen or colour where it's been touched up over the years
- Peeling, flaking or cracking, particularly on woodwork and around windows
- Yellowing on old gloss doors, skirting and frames
- Filler marks, hairline cracks or nail pops showing through
- The colour simply feels dated, or no longer suits how you use the room
If you're seeing several of these, a professional repaint with proper preparation will reset the clock for years, not just paper over it for a few months.
The cost-per-year test
Comparing decorating quotes on price alone is the wrong maths. Paint isn't a purchase, it's a subscription you pay up front, and the only number that matters is cost per year on the wall.
Take a hallway, the hardest-worked space in any house:
| Cheap quote | Proper job | |
|---|---|---|
| Price | £380 | £620 |
| Prep | Quick sand | Wash, fill, caulk, sand, spot-prime |
| Coats | Two, thinned | Two, full strength |
| Paint | Contract matt | Durable matt |
| Lasts | ~2 years | ~7 years |
| Cost per year | £190 | £89 |
The "expensive" quote is less than half the price. And that ignores the disruption of having decorators back in your hallway three extra times, and the fact that each repaint over failing paint gets harder, not easier.
This is the entire argument for proper preparation, expressed as a number. It isn't craftsmanship for its own sake. It's the cheaper option, and it only looks expensive on day one.
What actually kills paintwork, ranked
From what we're called out to fix, in order of frequency:
| Cause | How soon it shows | Preventable? |
|---|---|---|
| Painting over a dirty or greasy surface | 1–2 years | Entirely. Twenty minutes with sugar soap |
| Moisture and condensation | 6 months–2 years | Yes, but it's ventilation, not paint |
| Wrong finish for the room | 1–3 years | Entirely. A choice, not bad luck |
| Too few coats | 2–3 years | Entirely |
| Painting over a live problem | Weeks | Yes. Fix the cause first |
| Genuine wear | 5–10 years | No. This is the one that's allowed |
Notice that only the last row is normal. Everything else on that list is a decision someone made, usually to save an hour. If your paint failed in two years, it almost certainly wasn't the paint.
Does expensive paint last longer?
Honestly: less than the marketing suggests, and far less than good preparation.
Premium trade paint genuinely is better. More pigment, better binders, better opacity, better scrub resistance. It's worth using and it's what we include as standard. But the difference between a mid-range trade emulsion and a designer one is maybe a year on a wall.
The difference between proper preparation and skipped preparation is five years.
So if you have £60 spare on a room, spend it on prep time, not on upgrading the tin. The only exception is where the finish is doing real work: a durable matt in a hallway earns its premium because it's genuinely a different product with a different job, not just a nicer version of the same one. See our finishes guide.
How to make yours last even longer
Once it's done well, a few small habits genuinely extend it:
- Keep a labelled tin of each colour. Write the name and code inside a cupboard door. Touching up a scuff in year three is a five-minute job if you can match it, and a full wall if you can't.
- Wipe marks early and gently. A damp cloth on a fresh mark works. Scrubbing a set-in one burnishes the paint and leaves a shiny patch that's more obvious than the mark was.
- Never use abrasive or bleach-based cleaners on matt. They strip the surface and leave a permanent dull spot.
- Deal with leaks and damp immediately. Water behind paint is the fastest killer there is. See why paint peels.
- Ventilate. Run the extractor 20 minutes after a shower. It does more for your bathroom paintwork than any product.
- Keep furniture slightly off external walls. Air circulation prevents the mould that appears behind wardrobes.
- Touch up before it becomes a repaint. One scuff dealt with in year two can delay a whole-room job by a year or more.

How long should interior paint last?
Around 5–10 years. Bedrooms and living rooms often reach 7–10; busy hallways, stairs and kitchens may need refreshing every 4–6. Woodwork typically lasts 5–8 years.
Why does cheap paintwork fail early?
Almost always thin prep, too few coats, or economy paint. Proper prep and quality trade paint are what make a finish last, so the cheapest quote often costs more over time.
Does preparation really make paint last longer?
Yes, it's the single biggest factor. Filling, caulking, sanding and priming give paint a sound surface to bond to. Skip it and even the best paint fails early.
How often should I repaint my house?
As a rough guide, bedrooms and living rooms every 7–10 years, busy hallways, stairs, kitchens and bathrooms every 4–6 years, and woodwork every 5–8 years. High-traffic homes and families will be at the shorter end of those ranges.
Can I just paint over old paint?
Sometimes. If the existing paint is sound, clean and in the same finish family, a good clean and a couple of coats may be enough. But if there's flaking, damp, stains or a glossy surface, proper preparation (and sometimes priming) is needed first, or the new paint won't last.
