The question I get on almost every exterior quote is “how long will it last?” In the Eastern Suburbs the honest answer depends on which wall you are looking at, because the same house wears differently on different elevations.
Below I have split the signs into exterior and interior and said what each usually means. Not every sign means a full repaint: some mean a wash, some mean one elevation, and one or two mean the paint is only hiding a water problem.
Exterior signs: what I look for on each wall
Look at each elevation separately, because the same house has different lifespans on different walls. On a weatherboard house, where the damage is tells you more than what it looks like: one elevation peeling while the others are sound is an exposure problem, and every elevation peeling together is an adhesion problem, usually a previous coat put over chalk or salt. This is the table I work from, and the last column is what each sign usually needs.
| What you see | What it usually means | What it needs |
|---|---|---|
| White powder on your hand from the wall | Chalking: the binder is breaking down | Light chalking: a wash. Heavy chalking that comes back: repaint that elevation within a year or two |
| Colour noticeably faded on the north and west walls | UV wear, usually with chalking | Cosmetic until it chalks heavily; plan the repaint |
| Fine cracking, like a dry riverbed | The paint film has lost its flexibility | A repaint, because water is getting through those cracks |
| Peeling or flaking, especially at edges and sills | Adhesion has gone; water is under the film | A repaint soon, with proper preparation. Not paint over it |
| Blistering | Moisture or heat trapped under the coating | The water source found first, then the repaint |
| Rust stains bleeding through | Salt has reached the fixings | The metal treated and sealed, spot-primed, then recoated |
| Green or black growth on the south wall | Mould and lichen holding moisture | Treatment and a wash; if the film underneath is sound, no repaint |
| Grey, weathered bare timber | The timber has been unprotected for a while | Sanding back to sound fibres, priming and two coats, sooner rather than later |
| Paint peeling off rendered terrace walls in sheets | Usually trapped moisture: non-breathable paint over lime render | Full preparation and a vapour-permeable system; damp source first |
Close to the surf, salt gives its own warning: a dull grey bloom on the seaward wall, sometimes crystals on the sills. Salt holds moisture against the paint film, so a salt-coated wall is effectively damp all the time.
A wash is the first step of every exterior repaint, covered in pressure washing before painting. If the list of signs is longer than a wash can fix, see house painting and the free written quote.
Why the east wears paint faster: salt, sun, wind and shade
Salt settles on every exterior surface, blocks paint from bonding, and attacks the metal it can reach: nail heads, gutter brackets, window hardware and balustrade fixings. Sun breaks down the binder, so north and west walls chalk, then fade, and eventually stop shedding water.
Wind and temperature swings push rain and salt haze into places the overhangs would normally protect, and a west wall that is cold at dawn and hot by mid-afternoon is constantly expanding and contracting under the coating. Timber moves most, which is why weatherboard and trim have the shortest lives. Shade is the opposite problem: the wall that never sees the sun stays damp, grows mould and lichen, and the film degrades from underneath.
Where you live decides which dominates. On Coogee’s beachfront strip and Bronte’s beachfront streets it is salt. In Bronte’s sheltered gully, damp on south-facing walls is the recurring problem. In Kensington, three to four kilometres from the surf, salt is minor and the sun, shaded damp and simple age do the damage. See our Coogee, Bronte and Kensington pages, and the coastal paint guide for what survives salt.
Timber, render and terraces: where to look
Trim, sills and weatherboards
Timber and trim wear out before render. Sills, the bottom edge of every weatherboard, the tops of handrails and the gloss on window frames all go before the walls do. On a weatherboard house, the classic coastal failure is paint lifting along the bottom edge of the boards. Soft or split boards are carpentry, not paint, and get priced separately and done first. See painting a weatherboard house near the coast.
Render and heritage terraces
Cracked or hollow-sounding render has to be repaired before any paint goes on. Paint over it fails within a couple of years and takes more render with it.
Victorian and Federation terraces, like those in Paddington, are solid masonry with lime render that has to breathe. Seal it with a non-breathable acrylic and the moisture has nowhere to go, so it builds up behind the film and pushes the paint off. Most of the peeling-paint calls I get in Paddington trace back to that. Anything painted before 1970 is assumed to carry lead and is prepared lead-safe under AS 4361.2. If you are changing the external colour on an older home, check with your council first. Start with our Paddington page and the heritage terrace guide.
Apartments and strata blocks
In a strata block the external walls are usually common property, so a repaint goes through the owners corporation (the strata plan and by-laws are the final word). Act on facade signs early: paint is the building’s sacrificial layer, and once it fails, water gets at the render and a repaint can become a far bigger remediation job. See the strata painting guide.
Interior signs: mostly wear, not weather
Interiors are far less affected than exteriors. Paint inside usually goes 10–15 years before a full repaint, longer in rooms that get little use, and the main exception is damp.
- Ceiling stains and cracks. Nothing ages a room faster, and nothing makes buyers think “leak” quicker.
- Flaking sills and worn trim. Flaking window sills and decades of built-up gloss add hours to a repaint, and crisp trim makes even older walls look sharper.
- Scuffed walls and tired paint. If you are selling, tired paint gives buyers a visible reason to knock money off, and living, dining and kitchen walls are where they linger.
- Damp. Interiors go 10–15 years unless there is damp.
You do not have to repaint the lot at once. Interiors are done room by room in a sequence agreed with you, so the house stays liveable. As a guide, a single room runs $600–$1,500 and a full 3-bedroom house interior $6,000–$12,000; a walked, itemised quote is the only accurate number. House painting covers how an interior job runs.
Turning the signs into a timeline
These are my guide figures for a properly prepared, two-coat premium job.
| Where the house sits | Usual repaint interval |
|---|---|
| Walls taking direct salt, such as Coogee and Bronte beachfront streets | About 5–7 years |
| Exterior a few streets back | 7–10 years |
| Exterior a kilometre or more inland | 10–12+ years |
| Interior | Usually 10–15 years, longer in rooms that get little use |
A cheap job over poor preparation can be peeling inside two years wherever you live. Timber, trim and the north and west walls wear out first, so it is common to repaint the most exposed elevation early rather than the whole house. The detail is in how long exterior paint lasts near the beach.
Decks run on a different clock: an oiled deck near the beach every 12–18 months, a stained deck every 2–4 years. See oil, stain or paint and our deck restoration page.
When you ask me to look
When I walk a house, I am working out which of three jobs it is: a wash, one exposed elevation, or a full repaint. Every quote is itemised, names the exact product line and the number of coats, and includes a start date and an estimated number of working days. A full house exterior runs $8,000–$25,000+ depending on preparation, access and condition; the cost guide shows what moves it. Ask for a free written quote and I will tell you which job you have.
If the exterior is at year seven or eight on the coast and you may sell in the next couple of years, repaint before the campaign photos rather than after the building inspection. See the pre-sale guide.
Frequently asked questions
How do I tell if my house needs a repaint or just a wash?
A sound paint film under salt and grime usually needs a wash, and so does light chalking. Heavy chalking that comes back, fine cracking, peeling or flaking at edges and sills, blistering and grey bare timber all point to a repaint. If you are not sure, I will tell you which it is.
How often should I repaint the outside of my house near the beach?
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. These assume proper preparation and two full coats, and the most exposed wall usually needs attention first.
How often should I repaint inside?
Interiors usually go 10–15 years before a full repaint, longer in rooms that get little use, unless there is damp. If only one room is tired, a single room runs $600–$1,500.
Is peeling paint always a sign the house needs repainting?
Peeling means adhesion has gone and water is getting under the film, so it needs a repaint with proper preparation, not paint over the top. If the same patch has failed twice, or the paint is blistering, the water source has to be found first. A written workmanship guarantee covers peeling, flaking and blistering caused by how the job was prepared or applied, but not fair wear such as fading on a sun-facing wall.
