Floor sanding and polishing costs depend on the floor’s condition, the work included and the coating selected. A square-metre rate can help organise a budget, but it cannot tell you whether damaged boards, old adhesive, staining, furniture handling or difficult access are included.
For a useful Australian renovation estimate, start with a measured area and a professional inspection. Then separate sanding and coating from repairs and household disruption. The AUD examples in this guide are explicitly illustrative, with GST assumed included; they explain how to build and compare a budget rather than presenting an unverified national price average.
Confirm what the contractor means by polishing
The word polishing is used loosely in flooring conversations. One quote may describe a full sanding back to timber followed by a new coating system. Another may cover preparation and recoating of an existing finish. A cleaning or maintenance treatment is a different service again.
Ask the contractor to describe the proposed work in plain language. Confirm whether the existing coating will be removed, how repairs are handled and which products will form the new finish. This prevents a low-price comparison between services that aim for different results.
Distinguish a refresh from a full restoration
A surface refresh may be considered where the existing coating and floor condition permit it. More extensive wear, incompatible coatings or other problems may require a different approach. The contractor should assess suitability rather than choosing a method solely to meet a desired budget.
Ask what the proposed service will leave visible
Request a realistic explanation of scratches, dents, gaps and stains that may remain. A new coating can improve appearance without erasing every sign of age. Record any agreed limitations before work begins, especially where the homeowner expects a floor hidden under carpet to look like new timber.
Establish whether the floor can be sanded
Identify whether the floor is solid timber, engineered timber or a timber-look product. Its appearance alone may not be enough. Engineered timber requires assessment of the available timber face and manufacturer guidance; laminate and hybrid surfaces should not be treated as solid timber sanding projects.
Ask about previous sanding, remaining board thickness, exposed fasteners and damaged edges. The contractor may need to inspect accessible sections or obtain product information. Do not assume that a solid board can be sanded indefinitely.
Our comparison of engineered and solid timber flooring explains why construction affects refurbishment options. Establishing the floor type early avoids paying for a restoration scope that the material cannot support.
If older coverings or adhesives need removal, arrange appropriate assessment before disturbance. The floor-finishing quotation should not quietly absorb hazardous-material work into an ordinary preparation allowance. Read about asbestos checks before renovation when the existing materials are uncertain.
Measure the scope room by room
Prepare a simple plan showing each room to be treated. Include hallways, cupboards and small connecting areas if they are part of the finish. Mark thresholds where the work will stop and identify any stairs as a separate item.
Ask the contractor to confirm the measured area. A room’s nominal dimensions may include cabinetry or exclude awkward recesses, so agree how quantities are calculated. Keep the same plan when requesting multiple quotations.
Several small rooms can involve more edge work and interruptions than one open space of the same total area. Narrow passages, built-in furniture and difficult corners should be visible in the scope. An area-only comparison may overlook that difference.
- List rooms, cupboards and connecting spaces.
- Mark the boundaries of the new coating.
- Separate stairs, landings and unusually detailed areas.
- Record furniture, appliances and fixed obstacles.
- Identify access, parking and working-hour restrictions.
Use a transparent AUD budgeting model
The following rate range is an assumed sensitivity test, not a current market range: AUD $45–$75 per m² for a defined sanding-and-coating scope. GST is assumed included. Substitute actual contractor rates once the floor has been inspected.
For a hypothetical 60 m² floor, that assumed range gives a core work allowance of AUD $2,700–$4,500. The calculation shows the effect of rate changes, but it does not establish the final project cost because preparation, repairs and disruption may sit outside the rate.
In one illustrative straightforward project, allow AUD $3,300 for sanding and the specified coating, AUD $350 for minor agreed repairs, AUD $250 for protection and cleanup, and AUD $400 for furniture handling. The subtotal is AUD $4,300. Adding an AUD $500 reserve creates an AUD $4,800 working allocation.
For a more involved example, allow AUD $4,200 for the core work, AUD $1,200 for board repairs, AUD $700 for difficult preparation, AUD $500 for furniture handling and AUD $600 for temporary accommodation. The subtotal is AUD $7,200. With an AUD $800 reserve, the allocation becomes AUD $8,000.
These examples do not include structural repairs, hazardous-material removal, major moisture remediation or a new floor installation. They demonstrate why two homes with the same floor area can require different budgets without either contractor being unreasonable.
Keep a reserve separate from an allowance
An allowance covers a known item whose exact price remains uncertain. A reserve is money retained for unexpected work. Do not use the same amount for both and assume the budget still contains protection against surprises.
Carry the accepted scope into your renovation budget, with unresolved items clearly labelled. Replace estimates with agreed prices as information becomes available.
Inspect repairs before discussing the final colour
Loose boards, splits, previous patches and local damage can change the work substantially. Ask which repairs are necessary for a suitable finish and which are optional appearance improvements. A repair schedule with photographs makes that distinction easier to review.
Matching replacement timber involves more than selecting a similar colour. Board width, profile, species, grade and ageing may affect the result. Ask the contractor how closely a repair can reasonably blend and whether the proposed coating will make differences more or less visible.
Do not expect sanding to solve an active leak or movement problem. Those issues should be assessed at their source. Treat the floor finish as the final surface of a sound building element, not as a remedy for an unresolved defect beneath it.
Where the assessment identifies wider preparation issues, coordinate them with the principles in floor levelling and substrate preparation. The appropriate repair depends on the construction and the intended flooring system.
Set realistic expectations for stains and colour
The ATFA’s guidance on re-sanding older floors explains that both timber and coatings change colour over time. It also notes that existing stains can become more noticeable after sanding and may extend too deeply to remove fully.
That matters when only one room is being restored. A newly finished area may differ from an adjacent older finish even if the timber species is the same. Ask where a natural stopping point exists and whether extending the work is worth the additional cost.
Request a sample or test area where the contractor considers it practical. Compare the proposed finish on your timber rather than choosing from a generic colour card alone. The sample should represent the coating system, not merely a wet patch that temporarily darkens the boards.
Discuss how much character you want to retain. Some owners value visible age and repair marks; others prefer a more uniform appearance. Neither expectation should be left for the contractor to infer after sanding has begun.
Specify the coating system clearly
The coating affects appearance, use and future maintenance. ATFA’s coating guidance emphasises matching a system to the project and following manufacturer information. Ask the contractor to identify the actual product, sheen and maintenance expectations in the quotation.
Do not compare coatings only by the number of coats. Different systems may have different primers, application requirements and intended performance. The useful comparison is the complete specified system and its suitability for your floor.
Explain how the room is used: pets, dining chairs, direct entry from outside, office chairs and frequent entertaining can influence the discussion. Ask what everyday protection and care the selected finish needs.
Also request the relevant product information about ventilation, access and return to use. Avoid treating a low-odour description as a complete occupancy instruction. The contractor should give a schedule based on the actual coating and site conditions.
Plan household disruption before booking
Work backwards from when rooms need to be usable. Distinguish the contractor’s final visit from the time permitted for walking, replacing furniture, laying rugs or normal cleaning. These stages may have different product-specific requirements.
Decide where furniture will go and who moves it. Shifting everything into an untreated room may work for one stage but create a second move later. Compare that inconvenience with temporary storage or completing a larger connected area at once.
Confirm access to bedrooms, bathrooms and external doors while work proceeds. If the floor is the only route through the home, staged work may need careful planning or temporary accommodation. Include pets and children in the access discussion.
Add the agreed stages to your renovation timeline. A rushed return to normal use can undermine a carefully specified finish, so keep the manufacturer’s requirements visible when coordinating other trades.
Compare quotations on the same basis
Provide each contractor with the same room plan, photographs and expectations. Ask for site inspection where needed and request a written description of preparation, repairs, coating and exclusions. A quotation should make its assumptions understandable.
Confirm whether cleanup includes the surrounding rooms, what protection is provided and how waste is removed. Dust-control equipment can reduce disruption, but ask what practical cleaning remains for the homeowner rather than interpreting a marketing phrase as a promise of no dust anywhere.
Identify how variations will be handled if concealed damage or unexpected staining appears. Agree that additional work requires a defined scope and price before proceeding where practical. This is especially useful when the existing floor cannot be fully inspected until coverings are removed.
Use the wider approach in comparing renovation quotes to assess clarity, suitability and total scope alongside price. A short quotation is not automatically a simple project.
Separate stairs and detailed areas from open floors
A staircase has edges, risers, nosings and changes of direction that do not behave like a simple rectangular room in a quotation. Ask whether the contractor prices it per step or as a defined lump sum, and confirm which surfaces receive treatment. A landing may be included in the floor area while the flight is charged separately.
Built-in bench bases, fireplaces and narrow cupboard interiors can also add detailed work. Photograph these locations and ask how they will be finished. If an area will remain concealed beneath permanent joinery, discuss whether its treatment is necessary and how the boundary will be handled.
Access restrictions can have a similar effect. In an apartment, confirm the permitted work hours, equipment route, lift booking and protection requirements before accepting a schedule. These are practical project conditions that may affect labour and attendance. They should be included in the quotation when known, rather than treated as unexpected extras after the contractor has committed to a price.
Choose sensible savings
Reduce cost by simplifying scope where it does not compromise the result. Clearing furniture yourself may help if the contractor agrees and the move can be done safely. Coordinating painting and other dusty work before final coating can also avoid unnecessary disruption.
Consider whether every room must be completed now, but assess the visual transition before splitting the work. A staged plan that creates an unwanted colour mismatch may lead to another project sooner than intended.
Retain sound existing timber where suitable and avoid specifying a dramatic colour change without understanding the process. The most expensive choice can be a finish selected quickly and replaced because it never matched the homeowner’s expectations.
At handover, inspect the floor in ordinary room lighting, review agreed limitations and collect the care instructions. Keep the coating name and date with your records. A useful sanding budget pays for an appropriate restoration and a floor you know how to maintain, not simply the lowest advertised square-metre rate.
