How Much Does Floor Sanding Cost in Sydney? (2026 Price Guide)
If you have been searching for floor sanding costs in Sydney, you have probably noticed that prices vary quite a lot depending on who you ask. That variation is real and it makes sense once you understand what actually goes into the job.
This guide breaks down what you can expect to pay in 2026, what drives the price up or down, and how to know whether sanding is the right call for your floors.
What Does Floor Sanding Cost in Sydney in 2026?
For a standard residential job in Sydney, professional floor sanding and polishing typically costs between $65 and $75 per square metre. Most homes fall somewhere in the middle of that range – around $65 to $75 per square metre – depending on the condition of the floor and the finish chosen.
For a full project, that works out roughly as follows:
- Small room (20-30 m²): starts from $700 – $2,000
- Medium home (60-100 m²): starts from $2,500 – $6,500
- Large home (120-200 m²): starts from $6,000 – $14,000+
Premium finishes, significant repairs, or difficult access can push costs above $90 per square metre. Basic sanding with a water-based polyurethane finish on a floor in good condition sits at the lower end.
The Australasian Timber Flooring Association (ATFA) recommends using certified contractors for floor sanding work – not only for quality, but because an accredited professional will assess the floor’s actual condition before quoting, rather than giving you a figure without seeing it.
What Affects the Price?
Floor Condition
This is the biggest variable. A floor covered in deep scratches, staining, or worn coating requires more sanding passes to reach clean timber. That takes longer and uses more materials. A floor that has been well maintained needs far less work – and costs less as a result.
Timber Species
Different timbers respond differently to sanding. Hardwoods such as Blackbutt and Spotted Gum are resilient and straightforward to sand. Softer or older species may require more care and slower machine passes, which adds time to the job.
Floor Size
Larger areas generally mean a lower cost per square metre due to economies of scale. A 20 m² bedroom costs more per metre than a 120 m² open-plan living space because setup time, equipment, and travel are spread over more floor.
Number of Coats and Finish Type
A standard job includes sanding and two to three coats of finish. Common choices are water-based polyurethane, oil-based polyurethane, and hardwax oil. Water-based finishes are faster-drying and have lower VOC content, making them a popular choice for occupied homes. Oil-based finishes take longer to cure but offer a warmer, deeper tone. Premium finishes such as Bona-certified coatings – which AJ Flooring uses as a certified contractor – provide superior durability and UV resistance.
Repairs and Gap Filling
If boards have visible gaps, splits, or water damage, these need to be addressed before sanding begins. Gap filling with timber putty or flexible filler is typically charged separately and adds to the total.
Access and Layout
Narrow hallways, stairs, and rooms full of heavy furniture all add time. If the area is difficult to manoeuvre machinery around, expect the per-square-metre rate to increase slightly.
Sanding vs Full Replacement - Which Makes More Sense?
This is one of the most common questions homeowners ask. The short answer is: sanding almost always wins on cost, provided the boards are structurally sound.
Replacing solid timber flooring in a Sydney home can cost $100 to $180 per square metre or more once you factor in materials, labour, and subfloor preparation. Sanding and refinishing the same area costs a fraction of that – and you keep the original floor, which is often better quality than what you would buy today.
The exception is when boards are too thin to sand again (solid timber can typically be sanded 4-6 times over its lifetime), heavily warped, or damaged beyond repair. An experienced floor sanding professional will tell you honestly which situation you are in.
Our floor sanding and polishing service includes a thorough inspection before any work begins, so you get a clear picture of what is needed and why.
When Does a Floor Actually Need Sanding?
Most Sydney homes need their timber floors sanded every 7 to 10 years under normal use. Some signs it is time to act:
- Visible scratches that catch the light at an angle
- Dull or patchy areas that do not respond to cleaning
- Coating that is peeling, flaking, or worn through in high-traffic areas
- Water stains or discolouration from spills
- Boards that feel rough underfoot
Between full sands, a professional maintenance clean can extend the life of the coating and keep your floors looking fresh for longer. A Bona Deep Clean or recoat is often all a well-maintained floor needs.
What Is Actually Included in a Professional Sand and Polish?
It helps to know what you are paying for. A professional floor sanding job is not simply running a machine over the surface. A thorough job involves multiple stages.
First, the floor is inspected for loose boards, protruding nails, and any areas needing repair. Gap filling is done at this stage if required. The sanding itself is carried out in several passes with progressively finer grits, starting coarse to remove the old finish and flatten the surface, then moving finer to prepare the timber for coating.
After sanding, the floor is vacuumed and screened – a fine buffing pass that removes any sanding marks before the finish goes on. Two to three coats of finish are then applied, with light screening between each coat to ensure adhesion and a smooth result.
The total process typically takes one to three days for a standard home, depending on the area and the drying time required between coats. Water-based finishes dry faster – usually two to four hours between coats – which means less disruption to your household. Oil-based finishes can require 24 hours or more between coats.
Most contractors will ask you to stay off the floor for at least 24 hours after the final coat and avoid replacing furniture for 48 to 72 hours. Full cure – when the finish reaches its maximum hardness – typically takes around two weeks, so it is worth being careful with heavy furniture and floor mats during that period.
Choosing the Right Contractor in Sydney
Price is one factor, but it should not be the only one. Floor sanding is a skilled trade, and the difference between a careful, experienced operator and someone cutting corners is immediately visible in the finished result.
An uneven sanding job leaves chatter marks – subtle ridges across the floor that catch the light. Poor finish application shows as bubbles, brush marks, or uneven sheen. These are not minor issues; correcting them means sanding again.
The Australasian Timber Flooring Association (ATFA) maintains a database of accredited members who have been vetted against industry standards. Choosing an ATFA member significantly reduces the risk of a poor outcome. Also look for a contractor who is licensed, fully insured, and offers a written warranty on their work.
How to Get an Accurate Quote
Avoid any company that quotes you a firm price without seeing the floor. Proper pricing requires a site visit to assess the timber species, condition, finish type, room layout, and any repairs needed.
When getting quotes, ask:
- Is the quote all-inclusive (sanding, repairs, finish coats)?
- What finish product will you use, and is it water-based?
- Are you ATFA-accredited and fully insured?
- What is the cure time before I can walk on the floor and replace furniture?
