It’s a fair question, and the paint tin doesn’t help. How often you repaint in the east depends far more on where the house sits, what it’s made of and how it was prepared last time.
So this isn’t one number. It’s the standard I work to for an exterior, an interior and a deck, what pushes a house toward either end of each range, and where strata buildings fit. Every figure assumes properly prepared work. A cheap job over poor preparation can be peeling inside two years wherever the house is.
Exterior: where the house sits sets the cycle
Within a couple of kilometres you can go from direct onshore salt to almost none, and exposure sets the range. Salt pulls moisture out of the air and holds it against the paint film, so a salt-coated wall is effectively damp all the time. Add Sydney sun breaking down the binder in the paint, and wind pushing rain and salt haze into places roof overhangs would normally protect, and the coast shortens everything.
| Where the house sits | Typical exterior cycle | What mostly wears the paint there |
|---|---|---|
| Front row — walls taking direct onshore salt, within a couple of hundred metres of the surf (Arden Street in Coogee, Campbell Parade in Bondi, Marine Parade in Maroubra) | 5–7 years | Salt on the seaward wall and the sills |
| A few streets back — still gets the salt haze and the wind (for example, Bondi streets a few back from the beach) | 7–10 years | Less salt, plus chalk and mould |
| A kilometre or more inland (Randwick, Kensington, Queens Park, Paddington) | 10–12+ years | Sun on north and west walls, mould on the south side, general age |
These are exposures, not postcodes, and suburbs such as Coogee and Bronte contain more than one. Coogee is really three: the beachfront strip taking the full load of salt-laden onshore wind, an apartment belt of walk-up blocks, and the hill behind, far enough back that salt is a minor factor and UV on the north and west walls is the main enemy. Bronte splits three ways too, including a sheltered gully behind the park with less salt but less sun and airflow, so mould and damp on south-facing walls is the recurring problem.
Kensington is the other end. It sits three to four kilometres back from the surf, so salt is a minor factor. Sun on north- and west-facing walls, damp on shaded south walls and the age of the housing wear the paint out.
One house, several clocks
The same house can have different lifespans on different walls. The ocean-facing wall of a Maroubra home can need attention well before the sheltered side does, and the small stuff fails before the walls do: sills, the bottom edge of every weatherboard, the tops of handrails and the gloss on window frames.
Timber moves most, which is why weatherboard and trim have the shortest lives, and they wear out before render. That is why repainting the timber, trim and sun-facing walls on their own can stretch the interval on the rest of the house, and why an exposed wall that is going is worth recoating early rather than waiting until it has gone to bare timber.
What shortens the cycle, and what lengthens it
Exposure sets the range. These decide where in it a house lands.
- Preparation. Paint over salt, chalk or loose old coats has nothing to hold on to, and near the water it lets go within a couple of winters. Washing to a sound surface, scraping back to firm edges and sanding is most of the job, and it is where cheap quotes save their money. Our preparation standard spells out what “prepared” means.
- The wash. A coastal exterior should start with one, or the new paint bonds to the salt and chalk instead of the wall. Between repaints, a gentle fresh-water rinse of exposed walls, eaves, sills and railings once or twice a year is the cheapest thing you can do, and on a beachfront home it is typically the difference between five years and seven. Washing before painting covers what suits each surface.
- The coating system. Bare timber, bare render, rusty metal and chalky old paint each need their own primer, and two full topcoats matter: one coat “plus touch-ups” roughly halves the life of the job. A premium 100% acrylic exterior system, which for me means Dulux Weathershield, stays flexible and sheds water for years longer than a budget exterior paint. The coastal paint guide covers what survives here.
- Sun and colour. Sun chalks the north and west walls first. Dark colours run hotter, move more and fade faster than light and mid-tones, so dark trim on a light body is the sensible compromise.
- The material. A weatherboard wall is hundreds of small surfaces, each with a bottom edge and end grain, and paint fails at the edges first, so a weatherboard house needs its own approach. On an old terrace the walls need to breathe: non-breathable acrylic over lime render is why terrace paint peels.
- Water getting in. On a weatherboard house, if the same patch has failed twice, water is getting in somewhere and paint won’t fix it. Overflowing gutters soak the wall below, and plants hold moisture against the paint.
Interiors: a much longer clock
Interiors usually go 10–15 years before they need a full repaint, and longer in rooms that get little use. They are far less affected than the outside by how exposed the house is.
If there is damp, find the moisture source first, then repaint: on damp-affected walls paint is the last step, not the fix. And where one room is tired before the rest, a single room is quoted on its own, $600–$1,500 as a 2026 guide, so one worn room doesn’t mean repainting the whole house.
Decks run on a shorter clock
A deck is horizontal, it holds water, and in the Eastern Suburbs it sits inside the salt spray zone, so it doesn’t follow the wall schedule. Near the beach an oiled deck needs a fresh coat every 12–18 months, though a sheltered or south-facing deck can stretch closer to two years. A stained deck runs 2–4 years.
The oil, stain or paint comparison goes through the trade-offs, including why paint is a last resort and why the finish you choose sets your calendar.
Strata buildings and common property: a separate schedule
If you’re on a committee, the figures above aren’t the ones to use. Our strata guide publishes a separate schedule for common property, which the owners corporation pays for from the capital works fund. Lot owners paint inside their own lot.
| Strata common-property element | Typical repaint cycle | Coastal / exposed |
|---|---|---|
| External render and masonry | 8–10 years | 6–8 years |
| External timber and steel trim | 5–8 years | 4–6 years |
| Common-area interiors | 8–12 years | — |
| Car park / back-of-house | 10–15 years | — |
The trap on common property is deferral. Paint is the building’s sacrificial layer, and once it fails, water gets at the render.
Why a walk-through beats a rule of thumb
Everything above assumes properly prepared work on an average house, and yours may not be. A house with an ocean-facing wall and a sheltered side has two clocks on one building, and no table can tell you how far apart they are. Where the damage is tells you more than what it looks like. On a weatherboard house, one elevation peeling while the others are sound is an exposure problem. Every elevation peeling together is an adhesion problem, usually a previous coat put over chalk or salt.
Dirty and dull isn’t the same as failed either. Sometimes it is a sound paint film under a year of salt and grime, and what it needs is a wash. I’ll tell you which one you’ve got. (The signs a house really is due, such as heavy chalking, fine cracking and peeling at the edges and sills, are in the beach lifespan guide.)
For interior and exterior house painting, the free written quote starts with a walk around the house. It is itemised, names the exact product line and the number of coats, and spells out what preparation is included, so you can see what the number depends on. For budgeting across a cycle, the 2026 price guide has the ranges: $6,000–$12,000 for a 3-bedroom interior, $8,000–$25,000+ for a full exterior and $1,500–$5,000 for a deck restoration.
If the exterior is at year seven or eight on the coast and you’re selling within the next couple of years, repaint before the campaign photos rather than after the building inspection. The pre-sale guide covers where to spend first.
Frequently asked questions
How often should you repaint the outside of a house near the beach?
On a properly prepared premium job, about every 5–7 years on walls taking direct salt, 7–10 years a few streets back and 10–12+ years a kilometre or more inland. The most exposed wall usually needs attention before the rest, so repainting one elevation early is common. The beach lifespan guide goes into each band.
How often do interiors need repainting?
Usually 10–15 years before a full repaint, and longer in rooms that get little use.
Can I repaint just one wall or side of the house?
It can be. Timber, trim and the north- and west-facing walls wear out first, so repainting those on their own can stretch the interval on the rest. Whether it suits your house is a call to make on site.
How often should a deck be oiled or stained?
Near the beach an oiled deck needs re-coating every 12–18 months, and a sheltered deck can stretch closer to two years. A stained deck runs 2–4 years between coats.
How often does a strata building need repainting?
For common property, external render and masonry run 8–10 years, or 6–8 on exposed coastal elevations. External timber and steel trim run 5–8 years (4–6 on the coast), common-area interiors 8–12 years and car parks 10–15. These are strata figures, not house figures. The strata painting guide has the detail.
