Exterior House Painting Cost Guide: DIY vs Professional Estimates

Painting the outside of an Australian home typically costs between $3,500 and $20,000, depending on the size of the house, the number of storeys, the condition of the existing surface and whether you hire a professional or do it yourself. This guide breaks the numbers down so you can budget with confidence — and shows how our free estimator turns those figures into a quote in minutes.

Cost per square metre (AUD)

Australian painters usually quote exterior work by the square metre of wall area (not floor area). Typical 2025 ranges:

  • Single-storey weatherboard or render: $25–$40 / m²
  • Double-storey (access & scaffolding): $40–$60 / m²
  • Heritage or heavily prepped surfaces: $55–$85 / m²

A typical 3-bedroom single-storey home has around 180–240 m² of paintable wall area, which puts most jobs in the $6,000–$10,000 range before extras like eaves, gutters and trim.

Material costs: paint and primer

Materials are usually 15–25% of the total. Budget premium exterior acrylic paint at around $25 per litre retail (trade pricing is lower), covering roughly 10 m² per litre per coat. Most jobs need two topcoats, and previously unpainted or repaired surfaces need a primer coat as well.

  • Paint (2 coats, 200 m² house): ~40 L → about $900–$1,100
  • Primer/undercoat where required: ~$150–$400
  • Sundries (rollers, brushes, tape, drop sheets, filler): $150–$300

Labour rates and hours

Professional painters in Australia charge $55–$85 per hour for a tradesperson, and more when scaffolding, cherry-pickers or lead-paint precautions are involved. A rule of thumb for exterior work: one experienced painter covers about 6–10 m² of prepped wall per hour.

For a 200 m² single-storey home that's roughly 25–35 hours of painting, plus another 10–20 hours of prep (scraping, sanding, filling, masking). Prep is often the largest single line item — and the biggest reason DIY jobs run over budget.

DIY vs professional: side-by-side

A DIY job on a single-storey home usually lands around $1,500–$3,000 in materials plus 60–100 hours of your own time. Hiring a professional for the same job typically runs $6,000–$10,000 all-in, including GST.

The trade-off isn't just money — it's access equipment, warranty, preparation quality, and time. Double-storey work in particular is rarely worth doing yourself once scaffolding hire is included.

Frequently asked questions

How long does exterior painting take?

A professional two-person crew usually finishes a single-storey home in 4–7 working days, weather permitting. DIY jobs typically stretch over 3–6 weekends.

How often do I need to repaint the outside of my house?

In Australian coastal and northern climates, exterior paint lasts 7–10 years on rendered surfaces and 5–8 years on timber. Inland southern homes can stretch to 12+ years.

Registered painters must include 10% GST. Our estimator produces a GST-ready quote you can compare like-for-like with formal painter quotes.
