You pull into the driveway and see it again — the faded siding or the scuffed-up walls in the living room. You know it's time for a change, but the big question looms: how much does it cost to paint a house? While every project is different, industry data shows the average house painting cost to hire pros often falls between $3,000 and $20,000. That huge range exists because the final price depends heavily on your home's size, its current condition, and the prep work required before a single can of paint is opened.

Why Labour and Prep Work Are the Biggest Cost Drivers

When you get a quote from professional house painters, it's easy to focus on the price of the paint. Surprisingly, materials typically only make up 15–25% of your final bill. The vast majority of the cost, often 75–85%, is for the crew's labour. This labour cost covers much more than just brushing paint onto a wall; it's an investment in the meticulous prep work that ensures a lasting finish.

75–85% Labour Prep work, application, finishing
15–25% Materials Paint, primer, sundries

If your home has peeling paint, cracks, or dirty surfaces, a significant portion of the cost will go toward:

Cleaning & pressure washing — Removing dirt, mould, and chalky residue so paint can properly bond.
Scraping & sanding — Stripping away old, failing paint that would cause new coats to bubble and peel.
Patching & crack repair — Filling holes and repairing damaged drywall or siding for a smooth substrate.
Priming — Applying a special base coat that covers stains, seals the surface, and improves paint adhesion and durability.

Think of prep work as the foundation of the paint job. You can use the most expensive paint in the world, but if the surface underneath is flawed, the paint will bubble and fail. Paying for proper prep is an investment in making the final product last.

Exterior Painting Costs: What to Budget for a 3 Bedroom House

For a typical 3 bedroom house, the number of stories is a huge factor in the cost to paint a house exterior. Access, safety requirements, and the time taken for ladder or scaffold work all drive up the price significantly as you add height.

Single-Story Home

$5,000 – $10,000
  • Straightforward ladder access
  • Faster crew movement
  • Lower safety overhead
  • Less scaffolding required

Two-Story Home

$10,000 – $20,000+
  • Extensive ladder or scaffold work
  • Slower, more careful application
  • Higher safety requirements
  • Gables & high eaves add time

Intricate details like shutters, window trim, and gables also add to the time and expense. Your home's siding material matters too — wood siding often needs far more prep work than vinyl, adding hours to the labour bill.

Interior Painting Costs: A Room-by-Room Breakdown

The interior house painting cost per room typically falls between $350 and $800, depending on its size and the amount of trim and detail work involved.

$350 – $800 Per room — professional interior painting
$350+ Savings per room when bundling multiple rooms

A key choice that impacts both cost and durability is the paint's sheen:

Flat / Matte

  • Great at hiding surface imperfections
  • Softer, more subtle appearance
  • Harder to clean — marks show
  • Best for bedrooms & low-traffic areas

Glossy / Semi-Gloss

  • More durable and wipeable
  • Ideal for kitchens, bathrooms & trim
  • Reflects light, makes rooms feel larger
  • Slightly more expensive to supply

Keep in mind that hiring a professional for just one small room is less cost-effective. Bundling several rooms into one project lowers the average price per room and reduces the fixed call-out costs spread across the job.

DIY vs. Hiring a Pro: A Realistic Cost and Effort Comparison

On the surface, doing it yourself seems like the obvious way to save money. But the full picture is more nuanced than just the cost of a tin of paint.

DIY Project (Single Room)

$300 – $600
  • Paint, brushes & rollers
  • Tape, drop cloths & primer
  • Your full weekend of time
  • Risk of uneven coverage or drips
  • No warranty on the result

Hiring a Pro (Single Room)

$500 – $1,000
  • All-inclusive professional result
  • Completed in a single day
  • Proper prep included
  • High ceilings handled safely
  • Painters responsible for any errors

Beyond the dollars, factor in the hidden costs of DIY: your time and the risk involved. A project that takes a professional one day could consume your entire weekend. Pros are equipped to handle high ceilings safely and are responsible for any accidental paint spills or uneven finishes.

Your Action Plan: How to Get a Fair and Accurate Painting Quote

Follow the "rule of three" — always get detailed, written estimates from at least three different contractors. When a contractor visits, ask every painter these five questions:

1 Are you licensed and insured? A legitimate professional will carry public liability insurance and be able to provide their licence details on request.
2 What brand and sheen of paint will you use? The product used directly impacts the quality and longevity of the result. Ask for the specific product name.
3 How many coats of paint does the quote include? A single coat is rarely enough. Two coats is the industry standard for most surfaces.
4 What specific prep work is covered in this price? Ensure sanding, filling, and priming are listed clearly in the scope. Vague quotes often exclude this.
5 How will you protect my furniture and floors? Drop sheets, tape, and careful masking should be standard. Confirm this is part of the service.

Resist the urge to just look at the bottom-line price. Compare based on scope of work — does one painter include more prep work or higher quality paint? A thorough quote that seems slightly more expensive may promise a result that lasts years longer.
