Budgeting for Painting: Costs, Scope and What Impacts Price

Introduction

Painting may seem straightforward—a few tins of paint, a brush, a bit of time, and you’re done. But the reality is far more involved. Behind every finished wall is a chain of decisions that dramatically affect quality, longevity, and of course, the total price. Whether you’re freshening up a living room, protecting a rendered exterior from coastal weather, restoring a rusted roof, or applying a specialty coating to elevate your home’s look and value, painting is one of the most deceptively technical areas of residential renovation.

Costs vary not just by the square metre, but by a matrix of variables: surface conditions, height and access, number of coats, paint type, finish sheen, prep complexity, and more. Without a proper breakdown, it’s easy to misunderstand where your money is going—or get stung with a quote that seems cheap but fails to deliver. That’s where AIreno steps in.

This guide breaks down how to plan and budget your painting project, explains what impacts costs most, and introduces the tools we provide to ensure you quote and plan like a pro. Whether you’re a homeowner or a professional painter, you’ll walk away with a clear understanding of where every dollar goes.

What Does Residential Painting Cost in Australia?

Let’s start with the numbers. These are ballpark averages, and your actual quote may vary depending on location, scope, access, product choice, and painter experience.

• Interior painting: $25–$45 per square metre for walls, ceilings, trims (includes labour and materials)
• Exterior painting: $40–$65 per square metre depending on access, prep, material type (brick, render, timber)
• Roof painting: $2,000–$8,000+ depending on tile vs metal, steepness, number of coats, and required sealers
• Feature wall/specialty finish: $250–$1,500+ depending on materials and complexity (e.g. suede, metallics, murals)

These costs typically include standard prep (light patching, sanding), application of primer and two coats of a mid-range brand, and clean-up. However, they often don’t include things like:

• Mould treatment or damp sealing
• Heavy crack repairs
• Advanced coatings like anti-graffiti, rustproofing, or heat-reflective membranes
• Difficult access (multi-storey, steep terrain, tight eaves)
• Scaffolding or lift hire

AIreno takes these variables and turns them into a structured, dynamic quote—so you know exactly what’s driving the price and what’s optional.

The Hidden Costs (and Where to Save Without Compromising)

Not all costs are visible upfront. Here’s where things can catch you off guard:

• Poor surface prep: Paint will not adhere properly to a dirty, glossy, or flaky surface. If patching, washing, or sanding is skipped, expect bubbling or peeling soon after.
• Multiple colours: Every colour change requires cleaning, taping, and clean brushwork. It also increases the number of buckets and time spent.
• Changing from dark to light or vice versa: Often needs an undercoat or third coat to cover.
• Weather and season: High humidity or cold slows drying. Exterior work may take longer in winter.
• Urgent jobs: Want it done fast or after hours? Expect to pay more for the rush.

Savings? Here’s where smart planning makes a big difference:

• Stick to fewer colours
• Paint only high-impact areas (like living areas or entryways)
• Use washable low-sheen paint for practicality without splurging on high-gloss
• If ceilings or trims are still fresh, skip them
• Bundle interior and exterior work into one job to cut setup and clean-up costs

AIreno guides you through these decisions as you quote—so you get a tailored price based on real choices.

How AIreno Creates Transparent Painting Quotes

AIreno simplifies quoting into an interactive step-by-step workflow that collects everything a painter would ask:

1. Select project category: Interior, Exterior, Roof, Feature/Specialty
2. Choose surfaces to paint: Walls, ceilings, skirting, doors, window frames, cladding, fascia, eaves
3. Assess surface condition: Light, moderate, or heavy prep
4. Indicate access level: Easy, ladder only, needs scaffold, tight space
5. Choose finish quality: Budget, Standard, Premium, Specialty/Low-VOC
6. Add special requirements: Colour changes, additional coats, protection zones (near pools, gardens, etc.)
7. Instantly generate a quote with line-by-line pricing
8. Save, compare, or match with a painter based on availability, ratings, or past work

This process gives you not just a price, but an understanding of the scope behind the price—and options to adjust it.
