This guide is about how long paint lasts, not how long the job takes to do. If you want timelines for the actual work, see our companion guide on how long it takes to paint a house in Melbourne. Here we’re talking lifespan: how many years before you’re back up the ladder.

How long does interior paint last in a Melbourne home?

Interior paint in a Melbourne home lasts about 5 to 7 years on living and dining walls, with quieter rooms going longer. Inside, it’s wear and washing that age paint, not the weather, so the room and how hard it’s used matter more than anything else.

The room makes all the difference. An adult bedroom can go 6 to 10 years because almost nothing touches the walls. A hallway with kids, bags and the dog brushing past needs a freshen-up every 2 to 4 years. Kitchens and bathrooms sit around 3 to 5 years thanks to steam, grease and constant wiping.

Ceilings are the quiet achievers. They get no foot traffic and no UV, so a sound ceiling often holds a decade or more. We’ve repainted plenty of Melbourne ceilings that were easily fifteen years old and still perfectly sound underneath. Trim, doors and skirting land in the middle, usually 5 to 8 years, because they cop knocks and get cleaned often.

So is a “5 to 7 year” rule of thumb useful? Only as a starting point. A well-prepped job in a premium washable interior paint, looked after, can push past 10 years in the right room.

How long does exterior paint last in Melbourne?

Exterior paint in Melbourne typically lasts 5 to 10 years, though it swings hard with the surface and the sun. Melbourne’s harsh summer UV and damp winters work both ends against your paint, so the same product can last twice as long on one wall as another.

The big variable is what’s under the paint. Timber moves with heat and cold, so weatherboard runs at the shorter end. Render is more stable but porous, and painted brick is the most stable surface of the lot. Then there’s aspect. North and west walls take the brunt of the sun, and in our experience they always fade and chalk first while the shaded south side still looks fresh.

Coastal homes are their own story. Salt air and wind near the bay strip paint faster, so a place in Williamstown or Altona will usually need attention sooner than the same house in Glenroy. If you’re weighing up an exterior repaint, our exterior painting service page walks through the systems we use for each surface.

How long does paint last by surface? (interior vs exterior)

Paint lifespan depends as much on the surface as the paint in the tin. Timber moves and soaks up sun, so weatherboard runs short, while stable painted brick can hold for many years. Here’s how the common Melbourne surfaces stack up, inside and out.

These are typical planning ranges for Melbourne conditions, not promises. The same weatherboard wall can last 3 years or 8, and the deciding factor is almost always the prep.

What shortens the life of a paint job?

Poor preparation is the single biggest reason paint fails early. When a dirty, damp or flaking surface gets painted anyway, the new coat can’t bond and starts peeling within a couple of years. Everything else, sun, moisture and shortcuts, chips away from there.

Here’s what we see drag a paint job’s life down, in rough order of damage:

• Skipped prep. No washing, no sanding, no priming bare patches. The coat looks fine on day one and lets go by year two.
• Single thin coats. One stretched coat over budget paint gives you patchy cover and a short life.
• Sun and dark colours. UV breaks paint down, and dark colours absorb more heat, so they fade faster.
• Moisture and salt air. Rising damp, blocked gutters and bay-side salt all feed peeling, bubbling and mould.
• Cheap paint. Less pigment and weaker binders mean it chalks and fades years before a premium product would.

We’ve pulled boards off jobs where the last painter rolled straight over flaking paint to save a day. Two summers later the owner was paying twice. That’s the real cost of a cheap quote, and it’s why the lowest number on the page is rarely the best value. If yours is already letting go, our guide on how to fix peeling paint walks through the repair.

What makes a paint job last longer?

Proper prep and two full coats of premium paint are what push a job to the top of its range. Good preparation plus the right product is the gap between a coat that lasts four years and one that lasts ten.

So why does premium paint actually last longer? It carries more pigment and stronger binders, so it covers properly in two coats, holds its colour against Melbourne UV, and can be washed without rubbing through. We use Dulux exclusively for exactly this reason, and on exteriors that usually means Weathershield, which Dulux backs with a residential promise against peeling, flaking and blistering for as long as you live in the home.

The maths is simple once you spread it over the years. A job that lasts 10 years instead of 5 is half the cost per year, even if the upfront quote was a bit higher. That’s the value angle most cheap quotes hide, and it’s covered in our house painting cost guide for Melbourne.

Then there’s the work itself. We’re a family-owned team that has painted Melbourne homes since 1987, we do every job in-house rather than subcontracting it out, and we carry $20M public liability. Every job is backed by a written guarantee, which is only possible because the prep and the product are done properly every time.

How do you know it’s time to repaint?

The clearest signs are chalky, faded colour, hairline cracking, flaking, and paint that no longer beads water. On exteriors, fading and chalking mean the protective film is breaking down. Inside, scuffs you can’t wash off and patchy sheen are the usual giveaways.

Run a quick check once a year. Rub a clean cloth over a sunny external wall: if it comes away with a powdery film, the paint is chalking and protection is fading. Look for cracking around weatherboard joints and window frames, and check eaves and gutters for any peeling or mould. Catch it early and you’re repainting a sound surface, which is cheaper and lasts longer than waiting until bare timber is showing.

Not sure whether yours is genuinely due? A quick look from an experienced painter beats guessing. You can see the surfaces we work across on our Melbourne house painters page, or just send us a couple of photos.

Frequently asked questions

How often should you repaint a house in Melbourne?

Most Melbourne homes need an exterior repaint every 5 to 10 years and interior walls every 5 to 7 years. The exact timing depends on the surface, sun exposure and how well the last job was prepped. Weatherboard and high-traffic rooms come around sooner, brick and ceilings last much longer.

How long does exterior paint last?

Exterior paint typically lasts 5 to 10 years in Melbourne’s temperate climate. Weatherboard and timber run 3 to 7 years because the surface moves and bakes in the sun. Render sits at 5 to 10 years, while stable painted brick can hold 10 to 20 years before it needs another coat.

How long does interior paint last?

Interior paint lasts 5 to 7 years on living and dining walls, longer in quiet bedrooms and on ceilings. Hallways, kitchens and bathrooms wear faster, often 2 to 5 years, because of foot traffic, steam and cleaning. Wear and washing, not weather, are what age paint inside.

Does premium paint really last longer than cheap paint?

Yes. Premium paint like Dulux carries more pigment and stronger binders, so it covers in two coats, holds colour against UV and can be scrubbed without marking. Budget paint fades and chalks faster, often needing a repaint years sooner, which costs more once you add the labour back in.

Why does surface prep make paint last longer?

Prep is the single biggest factor in how long paint lasts. A clean, sound, properly primed surface lets the paint bond and stay put for its full life. Paint over dirt, damp or flaking old coatings and it can peel within a couple of years, no matter how good the tin was.

How long does Dulux Weathershield last on a Melbourne home?

Applied properly to a sound surface, Dulux Weathershield is built to last for years on a Melbourne exterior. Dulux backs it with a residential promise that it won’t peel, flake or blister for as long as you live in the home, provided it’s applied and maintained to instructions.

The bottom line

A paint job in Melbourne lasts about 5 to 7 years inside and 5 to 10 outside, but those numbers only tell half the story. The surface sets the range, and the prep decides where you land in it. Weatherboard and busy hallways come around fast; brick and ceilings can go for ages. The way to get to the top of every range is the same every time: proper preparation, two coats of premium Dulux, and a painter who doesn’t cut the job short to win it cheap.
