Average House Painting Costs in Wellington (2025)
For homeowners in Wellington, understanding house painting costs helps you budget accurately and avoid surprise quotes. In 2025, typical pricing ranges from $35 to $65 per square metre for interior painting and $40 to $75 per square metre for exterior painting, depending on surface condition, access difficulty, and paint quality.
A standard 3-bedroom Wellington home (approximately 120 m² of wall area) typically costs between $4,500 and $8,500 for interior work. Exterior painting for the same property generally runs from $5,500 to $11,000, with weatherboard homes on the higher end due to more surface area and prep work.
These figures include surface preparation, priming, two coats of premium paint, and clean-up. Complex architectural features, steep roofs, or multi-storey homes will push costs toward the upper range.
What Affects Painting Costs?
Several key factors determine your final painting bill. Surface condition is the biggest variable — walls with cracks, peeling paint, or water damage require extensive preparation before painting can begin. Homes in coastal Wellington suburbs like Island Bay or Seatoun often need extra attention due to salt-air exposure.
Accessibility directly impacts labour time. Scaffolding for multi-storey homes, steep sections, or roof painting adds significant cost. Tight urban sites in Thorndon or Mount Victoria may require specialised equipment that rural properties don't.
Paint quality matters for longevity. Premium brands like Resene Lumbersider or Dulux Weathershield cost more upfront but last 50% longer than budget alternatives. For Wellington's wind-driven rain and high UV exposure, premium exterior paint is essential.
Colour changes also affect price. Dark-to-light transitions typically need an extra coat or tinted primer, adding 15–20% to material costs.
Interior vs Exterior: Cost Breakdown
Interior painting is generally more affordable per square metre but can add up across multiple rooms. Ceilings add approximately $15–25 per m², while detailed trim and skirting boards run $25–40 per linear metre. Open-plan living areas are more cost-effective to paint than many small rooms due to reduced cutting-in time.
Exterior painting demands more labour and materials. Weatherboard cladding averages $50–70 per m², while painted brick or stucco ranges $40–60 per m². Roof painting is a separate specialist job, typically $55–80 per m² depending on pitch and roof type.
Wellington's unique climate — high winds, salt air in coastal areas, and strong UV — means exterior jobs need superior products and thorough preparation. Skimping on prep here leads to peeling and bubbling within 2–3 years.
Getting an Accurate Quote
The most reliable way to budget is requesting an on-site assessment. At RE Decorators, we provide free, no-obligation quotes across the Wellington region. Our assessors measure surface areas, evaluate condition, and recommend appropriate products for your specific location.
When comparing quotes, ensure all painters include the same scope: surface preparation, number of coats, paint brand and line, protection of non-painted surfaces, and clean-up. A suspiciously low quote often excludes essential prep work.
