Can't do everything this year? Here is where I would put the money first.
The logic is simple. Outside, the paint film is what stands between the weather and your walls. Inside, interiors are far less affected and usually go 10–15 years before a full repaint. I won't put a return figure on either choice. Below is how I'd think it through, using the 2026 price guides and repaint intervals I publish for house painting across the Eastern Suburbs.
Why a failing exterior goes first
Salt pulls moisture out of the air and holds it against the paint film, UV breaks down the binder that holds the film together, and onshore wind drives rain and salt haze into places the roof overhangs would normally protect. When the film fails, the weather reaches the substrate.
That is why I treat a failing exterior as the priority. Once the paint film is broken, water reaches the material behind it and the failure spreads from there. It starts at the weak points — sills and the bottom edge of every weatherboard. Timber left long enough goes grey and bare, and bare timber has to be sanded back to sound fibres before it can be primed. On the coast, waiting until the whole house needs it can mean the exposed side has gone to bare timber by the time you get to it.
Inside is different. Interiors are far less affected and usually go 10–15 years before a full repaint, unless there is damp. The intervals show the gap:
- Exterior walls taking direct salt: 5–7 years
- Exterior a few streets back from the beach: 7–10 years
- Exterior a kilometre or more inland: 10–12+ years
- Interiors: usually 10–15 years before a full repaint, longer in rooms that get little use
The exterior figures assume a properly prepared, two-coat premium job. The beachfront streets in Coogee and Bronte sit in the first band, and the full exposure bands are in how long exterior paint lasts near the beach.
Is it failing, or just dirty?
Before you decide, work out which one you have. A surprising number of “we need to repaint” calls turn out to be a sound paint film under salt and grime, and a proper wash buys them another two or three years. These point to a repaint:
- Peeling or flaking, especially at edges and sills: adhesion has gone and water is getting under the film
- Fine cracking like a dry riverbed: the film has lost its flexibility
- Heavy chalking that comes back after a wash
- Grey, weathered bare timber
Faded colour and green growth on the south wall are less clear-cut: fading is cosmetic until it chalks heavily, and mould can be treated and washed, with no repaint needed if the film underneath is sound.
If the film is sound, a wash costs far less than a repaint. As a guide, a standalone house wash on a typical Eastern Suburbs home is $400–$1,200, against $8,000–$25,000+ for a full exterior. There is more in pressure washing before painting.
When the exterior is bigger than the budget
If one elevation or the timber and trim are failing and a full exterior is more than you can spend, it does not have to be all or nothing. 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. The most exposed wall usually needs attention before the others, and repainting that elevation early beats waiting for the whole house.
On a terrace, the facade including iron lace and joinery has its own price guide (see painting in Paddington). A deck runs on its own clock: near the beach an oiled deck needs re-coating every 12–18 months and a stained deck every 2–4 years (oil, stain or paint).
When the interior goes first
If the exterior film is sound, the money is better spent inside. Start with the rooms that are actually worn. The spare room nobody uses can wait, since interiors last longer in rooms that get little use.
Water-stained ceilings are a special case: a stain can point to a leak, and paint will not fix water getting in, so find out whether water is still getting in before you repaint.
You can paint just a few rooms: a single room is a published guide item, and interiors are done room by room in a sequence we agree before we start, so the house stays liveable. A single room is $600–$1,500 as a 2026 guide, and high ceilings, heavy patching and a dark-to-light colour change push it toward the top. For a typical 3-bedroom house the same guide puts a full interior at $6,000–$12,000. These are broad guides, not quotes: preparation, condition, access and coastal exposure move every number, which is why I quote in person, in writing and itemised. The Sydney house painting cost guide covers the drivers.
Selling, or living in an apartment
If you are selling, the order changes. The pre-sale guide puts the facade and front entry first, then living, dining and kitchen walls, then ceilings with stains or cracks, then trims and doors, with bedrooms and hallways last. Inside wardrobes, garages and a full exterior when only the front is tired can usually be skipped. See repainting before selling.
If you own an apartment in a strata building, the choice is often made for you. The owners corporation paints common property such as external walls and render, hallways and stairwells, and lot owners paint inside their own lot. Your budget is the inside; a 2-bedroom apartment interior is priced in the cost guide. Check your strata plan and by-laws, because boundaries vary. The strata painting guide covers the committee side.
Your situation → what I'd do first
| Your situation | What I'd do first |
|---|---|
| Exterior peeling, flaking or cracking, or timber going bare | Exterior first. Repaint the failing areas with proper preparation and do not paint over failing paint. |
| Exterior dull and dirty but the paint is not lifting | Look before you repaint. A wash may be all it needs, and the money can go to worn rooms inside. |
| Beachfront home with one elevation failing and the rest sound | Repaint that elevation now and leave the rest, with the quote listing what is in and out. |
| Weatherboard with soft boards, grey timber or lifting bottom edges | Exterior first. Soft or split boards are carpentry, priced separately and done before any paint. |
| Water-stained ceilings | Check whether water is still getting in first, then repaint the ceiling. Paint will not fix water getting in. |
| Sound exterior, a few worn or tired rooms | Paint those rooms only and leave the exterior until the signs show. |
| Selling | Facade and front entry, then the main living areas, then stained ceilings. Wardrobes and garages can usually be skipped. |
| Apartment in a strata building | Spend inside your lot. The owners corporation handles the facade and common areas. |
Deciding what waits: what to ask for in the quote
Whatever you decide to leave for later, ask for the written quote to list every surface and room included, and which are excluded, so you can see exactly what is in the job. Every Proview quote lists every surface, room and repair, names the exact product line and number of coats, and gives a start date and an estimated number of working days.
You do not need to have chosen colours to get a quote: the work is quoted first and colour planning comes next. Colour planning covers whites, neutrals and accents that work together across connected rooms. We can also colour-match existing walls and trims.
If you are comparing painters, make each of them price the same list of surfaces and rooms, exclusions included; how to compare painting quotes has the wording. The 5-year written guarantee is stated on the quote, so check what the quote covers and what it leaves out.
Frequently asked questions
Should I paint the inside or outside of my house first?
If the exterior paint is peeling, flaking, cracking or the timber is going bare, do the outside first: it is what stands between the weather and your walls, and the failure spreads from the weak points. If the exterior is sound, spend only on the rooms that are actually worn, since interiors are far less affected and usually go 10–15 years before a full repaint.
Can I paint just one room, or just one side of the house?
For one room, the 2026 guide is $600–$1,500. On the outside, the most exposed wall usually needs attention before the rest of the house, so it is common to repaint one elevation early. 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, provided the quote states what is included and excluded.
How should I plan the exterior this year and the interior next?
If the exterior is failing, do it this year. Next year, paint the rooms that are actually worn; sound interiors usually go 10–15 years before a full repaint, longer in rooms that get little use. Ask for a written quote that lists every surface, room and repair included and excluded, so you can see exactly what is in the job before deciding what waits. Every Proview quote names the product line, coats, start date and estimated working days.
How do I know if my exterior needs a repaint or just a wash?
Peeling, flaking, fine cracking and heavy chalking that returns all point to a repaint. Paint that is dull, dirty or mouldy but still firmly stuck may only need washing and treating, and I will tell you which one you have when I walk the house.
How much does interior or exterior painting cost in Sydney?
For a typical 3-bedroom house the 2026 guide is $6,000–$12,000 for a full interior and $8,000–$25,000+ for a full exterior. Preparation, condition, access and coastal exposure move both, so a walked, itemised quote is the only accurate number.
