The price is driven by size, surface condition, access and exposure, not the paint on the tin. We quote from a site visit, so the price we give is the price you pay. There is no single number, and any painter who gives you one over the phone is guessing. What a job actually costs comes down to a handful of things you can see for yourself once you know what to look at. This guide breaks them down, gives indicative Perth ranges, and explains the one factor most quotes get wrong on the coast. ## What you are actually paying for Most of a paint job's cost is not paint. It is preparation: washing, stripping failed coating, filling, sanding, priming and sealing. On a sound, well-maintained home that work is quick. On a home that has been left, or was painted badly last time, it is most of the job. Two houses the same size can be thousands apart for this reason alone, which is why an honest quote comes from looking at the surfaces, not the floor plan. ## Interior vs exterior These are priced differently and it helps to think of them separately. **Interior** is driven by the number and size of rooms, ceiling heights, how much filling and sanding the walls need, and the finish you choose. A single room is often a day; a full interior is typically several days to a week. **Exterior** is driven by the size of the home, the number of storeys (access and scaffold change the price quickly), the cladding type, and how exposed the home is. Exterior is where the coastal factor below matters most. ## What drives the price In rough order of impact: 1. **Size:** wall area, not house size on paper. 2. **Surface condition:** sound paint is cheap to recoat; peeling, chalking or salt-damaged surfaces need real prep. 3. **Storeys and access:** a two-storey or steep-block home needs scaffold or height access. 4. **Cladding:** render, weatherboard, brick and fibre cement each prep differently. 5. **Finish and number of colours:** more cutting-in and more coats cost more. 6. **Exposure:** see below. This is the one most Perth quotes ignore. Estimate ### Estimate your repaint An indicative range for a Perth home. Every real quote comes from a site visit. What are you painting? Interior Exterior Both Home size Small (2–3 bed) Medium (4 bed) Large / two-storey Surface condition Good Average Needs work Exposure Inland Near coast Front-line Indicative range $5,000 – $9,450 Surface condition and exposure move the price most, which is why we quote from a site visit.

Not a quote. ## Indicative Perth ranges (2026) These are indicative Perth market ranges for 2026. Salt Coast quotes from a site visit; use these to set expectations, not as a fixed price. | Job | Indicative range (2026) | | --- | --- | | Interior, single-storey (3x1 to 4x2) | $7,000 to $14,000 | | Interior, double-storey / multi-level | $14,000 to $24,000 | | Exterior repaint, single-storey | $8,000 to $18,000 | | Exterior repaint, double-storey | $20,000 to $40,000 | - Whole home: add the interior and exterior rows together. - Double-storey adds roughly $800 to $2,500 for scaffold or elevated access. - Surface condition is the wildcard: a sound home that needs a recoat sits at the low end; a peeling, salt-affected or long-neglected exterior that needs real prep sits at the high end. Treat these as a starting point. The honest version of this number comes from a site visit, because surface condition alone can move it by thousands. ## How long will it take? A full interior on a family home is typically five to seven working days. A full exterior is similar. The disruption depends less on the size of the job than on how many painters are on site, a crew of four compresses what two painters do in twelve days into six. For a family living in the home, that difference is real: a week of people through your house instead of a fortnight. Exterior work on the coast also waits on the weather in one specific way: the salt wash and any repairs need to dry fully before coating goes on. Rushing that is how a finish fails at year two instead of year eight. ## Why a coastal home is quoted differently This is the part a standard Perth quote gets wrong. A home near the coast is a harder brief than one ten kilometres inland, and pricing it the same way is how you end up repainting in three years instead of ten. Salt settles into the surface and draws moisture back into the film. WA's UV breaks coatings down faster than almost anywhere. And wind drives both into every west and south-facing wall. Australia even has a standard that grades how corrosive a location is, **AS 4312**. The closer you sit to breaking surf, the higher the grade, and the more preparation and the better the coating system the home needs. It shows up in how often you repaint, too. Coastal Perth homes in suburbs like Cottesloe, Scarborough and Fremantle often need repainting every four to six years, where a sheltered inland home might stretch past ten. So a coastal exterior carries a little more prep and a coating specified for salt and UV. It costs marginally more up front and far less over the life of the home, because it does not fail early. A cheaper coastal quote almost always means the exposure was ignored. ## Before you sign a quote, ask about these eight things Any painter worth hiring will answer all of them without hesitation. A quote that answers them without being asked is the quote to take seriously. ![Eight things to check before signing a painting quote: salt removal, prep description, hollow render, coating system, fixed pricing, workmanship guarantee, crew size and timeline, crew consistency](https://saltcoast.com.au/assets/prep-checklist-eight-questions.svg) ## Keeping the cost down without cutting prep The two cheapest levers are honest ones: maintain the home so the next repaint is a recoat rather than a strip-and-redo, and wash salt off between repaints so coatings reach their full life. That is the whole logic of a [maintenance plan](https://saltcoast.com.au/maintenance-plans/), where a regular wash and a timely touch-up cost a fraction of stripping peeled paint. Cutting prep to save money does the opposite, it just brings the next full repaint forward. Written by [The Salt Coast Team](https://saltcoast.com.au/about/) Common questions ## FAQs **How much does it cost to paint a 3 bedroom house?** For a typical Perth three-bedroom home, a full interior runs around $7,000 to $10,000, a single-storey exterior around $8,000 to $13,000, and doing both together roughly $15,000 to $23,000. Condition and exposure move it most, which is why we quote from a site visit. **How much does it cost to paint a 4 bedroom house?** A four-bedroom home sits higher for the extra wall area: interior around $9,000 to $14,000 and a single-storey exterior around $11,000 to $18,000. A double-storey four-bedroom exterior is usually $20,000 to $40,000, with access and a larger surface area driving the upper end. **How much does interior painting cost in Perth?** It depends on the number and size of rooms, the prep needed, ceiling heights and the finish. A full interior for a small home is indicatively $7,000 to $10,000; a larger single-storey or four-bedroom runs $9,000 to $14,000; double-storey and multi-level homes sit higher again. **How much does exterior house painting cost in Perth?** For a single-storey home, indicatively $8,000 to $18,000; a double-storey runs $20,000 to $40,000, mostly for the additional wall area and access. Surface condition and exposure move it most within those ranges. **How long does it take to paint a house?** A single room is often a day. A full interior is typically several days to a week, and a full exterior similar, depending on size and prep. On the coast, exterior work also waits on weather, since salt washing and repairs need to dry before coating, and rushing that is how a finish fails early. **Should I paint the house myself or hire a painter?** For a small interior job in good condition, DIY can save on labour. Exteriors are where it rarely pays off on the coast: the cost is mostly in salt preparation, height access and a correctly specified coating, and getting any of those wrong means repainting in a couple of years instead of ten. A professional job also comes with a workmanship guarantee. **How long should a coastal repaint last?** Coastal Perth homes often need an exterior repaint every four to six years, against ten-plus for a sheltered inland home. Done properly, with real preparation and a coating specified for the exposure, you sit at the longer end of that. A cheaper job that skips coastal prep often fails within a couple of years. **Why do coastal homes cost more to paint?** Salt has to be washed out of the surface before painting, and the coating has to handle salt and heavy UV. That is a little more prep and a better system, which costs marginally more up front and far less over the life of the home.
