Interior Painting

Interior Painting near you

Interior painting is the one part of the Australian painting trade that can be booked in any month of the year, because the weather outside stops mattering once the windows are shut. What replaces the weather as the main constraint is the age of the house. A recently built home is a straightforward job of filling, sanding and coating. A home built before 1970 carries lead in its old paint films, and a home built before about 1990 may have wall and ceiling linings that are not plasterboard at all, which changes what may be sanded and by whom.

Licensing also treats inside work differently from the rest of the trade, and it catches people out. In New South Wales a stand-alone contract for internal paintwork has not needed a contractor licence since 2015, unless that paintwork forms part of other home building work. The moment your painter also does the eaves, or the painting is one line item in a kitchen renovation, the ordinary licensing threshold applies again. Queensland takes a different route entirely and licenses painting and decorating as a trade class through the QBCC regardless of which side of the wall it is on.

That leaves a homeowner comparing quotes on the things that actually decide how an interior job looks in five years: how much preparation is priced, what goes on bare and patched areas before the topcoat, how many coats are genuinely included, and what happens to the furniture and floors while the work runs.

When interior painting needs a licensed contractor in Australia

There is no single national painting licence. Each state and territory sets its own rule, and the New South Wales position is unusual enough to be worth stating plainly: a contractor licence is required for residential building and trade work, painting included, once the job passes a set value in labour and materials including GST, but stand-alone internal paintwork has been carved out of that requirement since 2015. The carve-out is narrow. It disappears as soon as the internal painting is part of other home building work, which is the usual situation in a renovation where the same contractor is also patching, tiling or rebuilding. Where a licence is required in New South Wales, it rests on a recognised qualification such as a Certificate III in Painting and Decorating.

Queensland does not draw the internal and external distinction at all. The QBCC issues a painting and decorating trade licence covering the application of paint and other substances for protective, decorative or technical purposes, including colour matching, texture coatings, wallpaper and the surface preparation that goes with them. One variant of the class also permits cement render up to a limited thickness, and a second variant excludes render. A licensee may pick up incidental work from other trade classes only up to a small set value, and may never take on work reserved for occupational licences such as plumbing or pest control.

The practical step is the same everywhere: ask which licence the business holds, in which state, and for what class of work, then check the number on the regulator's own public register rather than trusting a logo on a quote. If the answer is that no licence is needed because the job is internal only, confirm that the job really is internal only and really is stand-alone.

Lead paint inside homes built before 1970

LeadSmart NSW puts the era bluntly: lead paint was used in most homes built in Australia before 1970. Inside the house, the places it causes trouble are the places that get handled and knocked — window sills and sashes, door frames, skirting boards and architraves, where repeated friction grinds old coating into fine dust that settles on floors and window ledges at exactly the height a small child lives at.

The important thing for an interior repaint is that removal is not automatically the goal. Official advice is that paint in good condition is often best left alone or painted over, so a painter who proposes stripping every surface back in a pre-1970 house is choosing the option that generates the most dust. Where old paint genuinely has to come off, wet sanding and wet scraping are the safest ways to prepare a surface or remove lead paint, because they stop the dust becoming airborne in the first place.

The protective measures are specific rather than general good intentions. An AS 1716-approved respirator fitted with P1 or P2 filters is what the guidance calls for, and simple paper masks are singled out as inadequate because they do not fit well and do not protect against fine dust. Clean-up matters as much as the sanding: an industrial or HEPA vacuum that is not also the household vacuum, then wet-washing and wiping the whole work area and all hard surfaces including furniture, window sills and skirting boards with a phosphate detergent such as liquid sugar soap, followed by a clean water rinse. Waste is sealed in heavy-duty plastic and taken to an approved facility.

What the wall is actually made of, and why it decides the preparation

Australian interiors are not all plasterboard, and the difference is not visible once a surface has been painted. SafeWork NSW advises that a home built before the late 1980s may contain asbestos, and the Asbestos Safety and Eradication Agency records asbestos cement flat sheeting used for interior wall and ceiling linings prior to 1990 — a product its own guide notes can be mistaken for plasterboard, particularly when painted or wallpapered. A painter who assumes plasterboard and reaches for an orbital sander in a fibro-era house is making a decision about someone's lungs.

This is why the age of the building belongs in your first conversation, not in a discovery halfway through the job. Only a laboratory test at an accredited facility can confirm what a lining contains; age and appearance are reasons to test rather than reasons to conclude.

  • Modern plasterboard: paper-faced gypsum board, easily sanded, and the assumption most quotes are built on.
  • Asbestos cement sheeting used as interior lining before 1990: harder and more brittle than plasterboard, and indistinguishable once coated.
  • Solid plaster over masonry: common in older housing, unforgiving of moisture problems and prone to hairline cracking that reopens if only filled.
  • Timber linings, VJ boards and panelling: need the gaps and end grain sealed properly or the coating fails along every joint first.
  • Previously wallpapered walls: the paper and any residual adhesive have to be dealt with before coating, not covered over.
  • Wet-area linings in bathrooms and laundries: governed by their own rules, and not simply ordinary board with better paint on it.

How a careful interior repaint runs, room by room

  • Establish the age of the house and the lining type before anything is sanded, so lead and asbestos are settled questions rather than mid-job surprises.
  • Agree what gets moved, what gets covered and who does the moving, including whether the crew shifts heavy furniture or you clear the rooms first.
  • Wash down surfaces to remove cooking residue, smoke film and the greasy band that builds up in kitchens and hallways, because coatings do not bond through it.
  • Fill, patch and make good: nail pops, cracked cornice joints, gouges and old fixing holes, each brought back flush rather than bridged.
  • Sand and dust off using the safest method the substrate allows, with wet methods on older coatings.
  • Prime the bare, patched and repaired areas with a primer chosen for that surface, since patches left unprimed flash through the finish as dull spots.
  • Apply the finish coats at the coverage rate and recoat interval the manufacturer states, resisting the temptation to stretch a tin across one more room.
  • Cut in, then inspect in raking light from a window, which is where missed holidays and thin edges actually show up.

Painting indoors through an Australian year

Interior work runs all year in Australia, but the calendar still changes how it behaves. Summer, December to February, is the fastest drying and the most awkward to live through, because rooms have to be closed up or opened up at the wrong moments and touch-dry can arrive before a wall has been properly laid off. In a humid coastal or northern summer the opposite problem appears: recoat times stretch, and a second coat applied too early stays soft.

Winter, June to August, is not the dead season an overseas guide would suggest, but it is the slow one. Shorter days, cooler rooms and damp air all lengthen drying, and closed-up houses in the southern states ventilate poorly at exactly the time ventilation matters. If the job involves strong-smelling products, plan where the household will sleep rather than discovering the problem at nine at night.

Autumn and spring are the easy windows in most of the country, with mild temperatures and enough airflow to ventilate rooms without heating or cooling the whole house for a week. Whatever the month, the useful question to ask a painter is how they will ventilate each room and how long before furniture goes back.

Bathrooms, laundries and kitchens: where paint is not the whole answer

Homeowners often expect a bathroom repaint to solve a moisture problem, and it will not. In Australia, wet areas are regulated construction rather than decoration: the National Construction Code requires building elements in wet areas to be protected with a waterproofing system, referencing AS 3740 for wet area waterproofing. The Code's housing provisions list what counts as a water-resistant substrate for walls — including water-resistant plasterboard, compressed fibre-cement sheeting to AS/NZS 2908.2, cement render treated to resist moisture movement, and masonry — and set out separate requirements for waterproof materials, with membranes complying with AS/NZS 4858.

The practical reading for a repaint is that a mould-resistant coating is the finish on a correctly built wall, not a substitute for one. If paint is bubbling behind a shower, lifting at the skirting in a laundry, or blooming back within months of being cleaned and recoated, the fault is usually water reaching the substrate or a ventilation problem, and it needs to be found before anyone opens a tin. A painter who points that out before quoting is telling you something worth more than the quote.

Written scopes, consumer guarantees and getting interior painting quotes on LokalMatch

Australian Consumer Law gives you guarantees on services that no business can remove: services must be carried out with an acceptable level of care and skill, must be fit for any particular purpose you made known, and must be supplied within a reasonable time when no time frame was agreed. The ACCC states the basic rights covered by consumer guarantees cannot be taken away by anything a business says or does, and that misleading consumers about those rights is against the law. Get the scope in writing anyway, because most interior painting disputes are arguments about what was included rather than about the law.

In New South Wales there is a further layer for larger jobs: home building work above a set contract value must be in writing, deposits are capped as a share of the price, progress payments have to relate to work actually carried out rather than time elapsed, and statutory warranties apply automatically — six years for major defects and two years for other defects — including that the work be done with due care and skill. Variations should be in writing and signed by both parties, which is the single habit that prevents the most arguments.

LokalMatch is how you reach the painters in the first place. You describe the job once — the rooms, the ceilings and trim, the age of the house, your postcode and your timing — and painters working in your area contact you directly. Those businesses pay LokalMatch for the requests they receive, which is how the service is funded; describing a job costs a homeowner nothing. LokalMatch does not carry out painting, does not quote or set prices, and does not vet, rank or recommend any business, so checking licences, insurance and past work remains yours to do.

Interior Painting: frequently asked questions

Does my painter need a licence to paint the inside of my house?

In New South Wales, often not. Since 2015 a stand-alone contract for internal paintwork has not required a contractor licence, unless the paintwork forms part of other home building work — so an interior-only repaint can sit outside the requirement while the same painter doing the exterior, or painting within a renovation, does not. Queensland licenses painting and decorating as a QBCC trade class either way. Ask your own state's building regulator, since the rule is not national.

My house is from the 1960s. Should the old paint be stripped back?

Not as a default. Lead paint was used in most homes built in Australia before 1970, and stripping is what turns a stable coating into airborne dust. Official advice is that paint in good condition is often best left alone or painted over. Where old paint must come off, wet sanding and wet scraping are the safest methods, with an AS 1716-approved respirator fitted with P1 or P2 filters rather than a paper mask.

Can the painter sand my walls if the house is older than 1990?

Only once you know what the lining is. Asbestos cement flat sheeting was used for interior wall and ceiling linings prior to 1990 and can be mistaken for plasterboard, particularly when painted or wallpapered, and SafeWork NSW advises that homes built before the late 1980s may contain asbestos. Power tools must not be used on asbestos-containing material unless the equipment is enclosed or designed to capture or suppress the fibres. A laboratory test at an accredited facility is the only way to be sure.

Will a mould-resistant paint fix my bathroom?

Not if water is reaching the wall. Wet areas in Australia must be protected with a waterproofing system under the National Construction Code, which references AS 3740, and the Code lists the water-resistant substrates permitted for wet area walls. Paint is the finish on a correctly built and ventilated wall. Bubbling behind a shower or lifting at a laundry skirting points to the substrate or the ventilation, and repainting over it buys a few months at best.

How many coats should an interior quote include?

Ask rather than assume, and get the answer written into the scope along with what happens on bare and patched areas. Patches that are filled and sanded but not primed will show through the finish as dull or uneven spots no matter how many topcoats follow. The number of coats, the primer used on repairs, and the recoat interval the manufacturer specifies matter more to the result than the brand on the tin.

What should I do with furniture and floors while the work happens?

Settle it before the crew arrives. Agree in the written scope who moves heavy furniture, what gets covered, and whether rooms are handed back one at a time or all at the end. In a pre-1970 house this matters more than convenience: clean-up after any sanding of old paint involves an industrial or HEPA vacuum and wet-washing hard surfaces including furniture, window sills and skirting boards with a phosphate detergent, then rinsing.

What affects the cost of interior painting

Prices depend on the details of your project. We only publish price ranges when they’re backed by real LokalMatch quote data or reliable sources. Until then, here’s what usually changes the price:

  • Size of the area and ceiling height
  • Condition of the walls, trim or siding
  • Amount of prep and repairs
  • Number of colours and coats
  • Paint quality
  • Access, including stairwells and upper floors

How to compare painters before you hire

  • Ask how the painter will prepare the surfaces, since patching, sanding and priming matter as much as the paint.
  • Get a written quote that lists which rooms or surfaces are included, the number of coats and who supplies the paint.
  • Ask how they'll protect floors, furniture, landscaping and anything they can't move.
  • In older homes, ask how they handle old paint that may contain lead.
  • Look at recent work, paying attention to clean lines at ceilings and trim.

Questions to ask painters before you hire

  • What prep work is included, such as patching, sanding, caulking and priming?
  • How many coats are included, and what paint will you use?
  • Are ceilings, trim, doors and closets part of the price?
  • How will you protect my floors, furniture and plants?
  • Can you show me proof of liability insurance?
  • What happens if I notice touch-ups needed after you finish?

Interior painting permits and local rules

Some interior painting work needs a permit or has to meet local bylaws. Rules vary by municipality, so ask your pro whether a permit is needed and who will apply for it — and check with your city or town if you’re unsure.
