If you’re planning to give your home a fresh coat of paint, one of the first questions you’ll ask is: how much does it cost to paint a house in Perth? The answer depends on several factors from the size of your home to the type of paint you choose and the amount of prep work involved. In this guide, we break down everything you need to know about interior and exterior house painting costs in Perth for 2026.
Average House Painting Cost in Perth
The average cost to paint a house in Perth ranges from $3,000 to $12,000+, depending on whether you’re painting the interior, the exterior, or the entire home. Here’s a quick overview of what you can expect to pay:
| Painting Type | Average Cost (Perth) |
|---|---|
| Interior painting (full home) | $3,000 – $7,500 |
| Exterior painting (full home) | $4,500 – $12,000 |
| Interior + Exterior combined | $7,000 – $18,000+ |
| Single room interior | $400 – $900 |
These are average costs and can vary based on your home’s condition, accessibility, and the professional painters you hire.
How Much Does a Painter Cost Per Hour in Perth?
When it comes to labour costs, most house painters in Perth charge an hourly rate of $45 to $80 per hour, with experienced tradespeople often sitting at the higher end of that range. Some professional painters may also quote on a per-project basis rather than hourly rates, which can sometimes offer better value for larger painting projects.
For a standard 4-bedroom home, expect the total labour costs to make up 70–80% of the overall budget. This is why getting multiple quotes from house painters is always a smart move.
Interior House Painting Cost in Perth
Interior painting costs in Perth are influenced by the number of rooms, ceiling height, condition of walls, and whether prep work is required (such as filling cracks or sanding surfaces).
Here’s a general breakdown of interior painting costs:
- Single room: $400 – $900
- 2-bedroom unit/apartment: $1,800 – $3,500
- 3-bedroom home: $2,500 – $5,000
- 4-bedroom home: $3,500 – $7,500
Interior painting costs also go up if you have feature walls, cornices, skirtings, or window frames that need attention. Premium paints will also add to the total cost, but they’re worth it for a longer-lasting, more durable result.
What’s Included in Interior Painting?
A quality interior painting job typically includes:
- Surface preparation (filling, sanding, priming)
- Painting of walls and ceilings
- Painting of window frames and doors
- 2 coats of paint as standard (some painters include 3 coats with premium paints)
- Final clean-up
Exterior House Painting Cost in Perth
Exterior house painting cost in Perth is generally higher than interior work due to the additional prep work involved, equipment needed (like scaffolding), and the exposure to Perth’s harsh sun and climate.
The average cost to paint the exterior of a house in Perth is:
Small home (under 150 sqm): $4,500 – $6,500
Medium home (150–250 sqm): $6,000 – $9,000
Large home (250+ sqm): $9,000 – $12,000+
Costs are often calculated per square metre, with most Perth painters charging $12 to $30 per square metre for exterior work, depending on accessibility and surface condition.
What Affects Exterior Painting Cost?
Several factors influence your exterior paint job price:
- Size of the home – More square metres means more materials and time
- Prep work required – Scraping, pressure washing, and priming can add to costs
- Type of paint – Premium paints cost more upfront but last longer
- Roof height and accessibility – Two-storey homes require scaffolding, adding to labour costs
- Painting the exterior surfaces – Cladding, brick, render, and weatherboard all require different approaches
Key Factors That Affect Your Total House Painting Cost
Whether you’re looking at interior painting costs or an exterior paint job, several variables will affect your final quote:
1. Prep Work Good prep work is the foundation of any long-lasting paint job. This includes pressure washing, filling gaps, sanding, and priming. Skipping this step may save money now but cost more down the track.
2. Type of Paint Low-sheen, semi-gloss, and premium paints vary in price. Premium paints often provide better coverage, requiring fewer coats which can reduce labour costs overall.
3. Size and Complexity The larger and more complex the home (multiple storeys, ornate window frames, detailed trims), the higher the total cost.
4. Number of Coats Most professional painters apply 2 coats. Older homes or those switching from a dark to a light colour may require 3 coats, increasing the overall cost.
5. Condition of Surfaces Homes with significant wear, water damage, or peeling paint require more prep work before a fresh coat of paint can be applied.
Tips for Reducing House Painting Costs in Perth
- Get at least 3 quotes from licensed house painters
- Do some prep work yourself (moving furniture, filling small holes)
- Choose mid-range paints rather than the cheapest option quality matters
- Plan your painting project during off-peak periods when painters may be more competitive on price
- Bundle interior and exterior painting into one project to potentially negotiate a better rate
Should You DIY or Hire Professional Painters?
While a DIY approach may seem cheaper, a professional painter brings expertise, the right equipment, and access to trade-grade premium paints. For large or complex jobs especially painting the exterior professional painters deliver better results, save time, and often provide a warranty on their work.
For smaller interior rooms or low-risk areas, a confident DIYer can save money. But for your whole home, the quality difference and time savings make hiring professional painters well worth the investment.
