How much does it cost to paint a house in Sydney? It’s the first question most people ask, and the honest answer is that there’s no single number, because every home and every job is different. What you can do is understand what shapes the price, so you’re not comparing apples with oranges when the quotes come in. Mi Painting & Maintenance has painted homes right across Sydney for over 40 years, so this guide breaks down the real cost drivers behind a house paint job and shows you how to get an accurate quote for your residential painting services.
| Quick answer
The cost to paint a house in Sydney depends mainly on size, number of coats, surface condition and interior versus exterior work. Rather than a fixed figure, the smart approach is to understand the cost drivers so you can compare quotes fairly and avoid surprises. This guide explains what shapes a painting quote and how to get an accurate one. |
What actually drives a house painting quote?
A painting quote isn’t plucked out of thin air. It’s built up from a handful of factors, and knowing them helps you see why two quotes can differ. The main drivers are:
- Size and number of rooms: the more wall and ceiling area, the more paint and labour, so square metreage is the starting point.
- Ceiling height: high or raked ceilings need more access equipment and time than standard rooms.
- Surface condition and prep: cracked, patchy or previously poorly painted walls need more preparation, which is where a lot of the labour goes.
- Number of coats: a colour change, bare surfaces or a big contrast often needs an extra coat, which adds paint and time.
- Paint quality: premium and specialty paints, such as low-VOC, washable or weatherproof products, cost more per litre but often last longer.
- Access and scaffolding: two-storey exteriors, stairwells and hard-to-reach areas need scaffolding or platforms, which adds cost.
- Interior versus exterior: exterior work usually needs more prep, weatherproofing and access gear than interior work.
Add these together for your specific home and you get a real figure, which is exactly why a good painter wants to see the job before quoting rather than guessing over the phone.
Interior vs exterior painting costs: what’s the difference?
People are often surprised that exterior painting can cost more per square metre than interior, and it comes down to what the job involves. Interior painting is largely about preparation, cutting in and clean, even coats in a controlled environment, and quality interior painting is as much about neat lines and protecting your floors and furniture as the paint itself. Exterior painting has to battle the elements. It usually needs more thorough preparation, sanding back flaking areas, filling and sealing, treating any mould, and weatherproof coatings that stand up to Sydney’s sun, rain and salt air. It also more often needs scaffolding or height access, and it’s weather-dependent, since you can’t paint an exterior in the rain. All of that adds time and equipment, so while a single interior room can be quick, a full exterior repaint is a bigger undertaking, and the quote reflects it. It’s also why painters often quote the two separately, so you can see where the cost sits and decide whether to do both at once or stage them over time.
How surface preparation changes the price (and why cheap quotes skip it)
Here’s the part that separates a lasting paint job from one that peels in a couple of years: preparation. Prep is the unglamorous, time-consuming work that happens before any topcoat goes on, washing the surface, sanding, filling cracks and holes, repairing damaged plaster, sealing and priming. It’s also the easiest place for a cut-price quote to save money, because you can’t see what was skipped until the paint starts failing. A cheap quote that glosses over prep often costs you more in the long run, when you’re repainting far sooner than you should have to. If your walls have cracks, dents or damaged render, proper plastering and surface repairs before painting are what give you a smooth, sound surface that holds the finish. When you’re comparing quotes, the amount of preparation included is one of the biggest reasons prices differ, so it pays to ask exactly what prep each quote covers. A quick way to test a quote is to ask how much time is set aside for preparation versus painting; if prep barely rates a mention, that tells you something.
How to compare painting quotes like-for-like
To compare quotes fairly, you need to make sure they’re quoting the same thing. Before you decide, check each quote covers:
- Scope: exactly which rooms, walls, ceilings, trims and areas are included.
- Surface preparation: what cleaning, sanding, filling and repairs are part of the price.
- Number of coats: how many coats, and whether a primer or undercoat is included.
- Paint brand and quality: which products, and what sheen or finish.
- Licence and insurance: that the painter is properly insured and holds the appropriate credentials. Mi Painting holds a NSW plastering licence (244708C).
- Warranty and inclusions: what’s guaranteed, plus clean-up and rubbish removal.
When every quote spells these out, you can compare the real value rather than just the bottom-line figure, and a low number with vague prep or fewer coats usually isn’t the bargain it looks. Line the quotes up side by side on these points and the right choice usually becomes clear.
Questions to ask before you accept a quote
A few quick questions tell you a lot about who you’re dealing with:
- Is the quote fixed and in writing, and what could change it?
- What preparation is included, and how many coats?
- Are you insured, and what’s covered if something’s damaged?
- What’s the timeframe, and how do you handle weather delays?
- Do you clean up and remove rubbish when you’re done?
Frequently asked questions
What’s included in a professional house painting quote?
A proper quote should spell out the scope (which areas), the surface preparation, the number of coats, the paint brand and finish, and the clean-up. It should be a fixed price in writing after the painter has seen the job. Anything vague, especially around prep, is worth querying before you accept.
Is it cheaper to paint the interior or exterior of a house?
Per square metre, interiors are often cheaper, because exterior work usually needs more preparation, weatherproofing and height access. That said, it depends on the condition and size of each. A weathered, two-storey exterior costs more than a few tidy interior rooms, while a full interior repaint can outprice a small, sound exterior.
How long does it take to paint a house in Sydney?
It varies with the size, the amount of preparation and whether it’s interior or exterior, so a single room might take a day while a full house takes longer. Exterior work is also weather-dependent. Your painter can give you a realistic timeframe once they’ve seen the job and its condition.
Does surface preparation really affect the final cost?
Yes, significantly. Preparation is often the largest part of the labour, and it’s where cheap quotes cut corners. Skipping proper prep leads to paint that fails early, so you pay again sooner. A well-prepared surface costs more up front but gives you a finish that lasts, which is better value over time.
