Perth Exterior Painting Cost Calculator.Know what it should cost in Perth.

In Perth, exterior house painting typically costs between $4,725 and $18,900 in 2026, with most projects landing around $9,975. Pricing varies with size, finish level, complexity and your specific site.

A quality exterior system on stable substrate should last 8–12 years before recoating. Weatherboard and coastal homes are at the shorter end of that range.

If your roof is structurally sound but tired, painting it during the same project is significantly cheaper than scheduling a separate job — scaffolding and prep are already in place.

Late autumn and spring tend to be ideal in most of Australia. Avoid extreme heat (>32°C) and rain — both compromise paint adhesion.

For most freestanding homes, no. Approval can be required if the property is heritage listed or sits within a heritage overlay, where councils may control external colours and finishes. If you're in a strata scheme, exterior colours are usually a common-property decision, so check with your owners corporation first.

A standard single-storey home typically takes around a week, including washing and prep. Two-storey homes, heavy weatherboard repair or scaffold-dependent access can stretch the job to two or three weeks. Weather delays are common, so build some flexibility into your timeline.

A proper quote itemises pressure washing, surface preparation and repairs, the number of coats, the specific paint system, and any access equipment such as scaffolding. When comparing quotes, look at the prep detail and paint specification rather than the total alone. The cheapest quote often cuts prep, and prep is what determines how long the job lasts.
