WHAT OUR CUSTOMER SAY
Hardwood floors are the pride of many Australian homes, offering both aesthetic appeal and durability. However, like all things pretty, it requires periodic care to maintain its lustre especially since you’re stepping on it all the time.
And one of the most common questions homeowners ask is, “How much does floor sanding cost?” This guide aims to provide a comprehensive answer, breaking down the costs and factors that influence them.
Average Cost of Floor Sanding
Before diving into specific cost ranges, it’s important to understand that floor sanding is not a “one price fits all” service. The total investment depends on the floor’s condition, how many rooms are being worked on, and whether the job requires additional preparation such as removing old coatings or adhesives. These variables explain why quotes for seemingly similar homes may differ.
In Australia, the cost of floor sanding is typically calculated per square metre, making it easier for homeowners to estimate expenses based on the size of their space.
On a national scale, homeowners can expect to pay between $25 and $40 per square metre for floor sanding. This range isn’t arbitrary but is derived from extensive market research, encompassing quotes from various professionals across different states and territories. It’s worth noting that while this is the average range, prices can fluctuate based on several factors, including the specific region, the expertise of the professional hired, and the current demand for floor sanding services.
Why Square Metre Pricing Varies
Even though pricing is advertised per square metre, professionals rarely calculate costs using this number alone. Other considerations include:
- Time required for detailed edge sanding
- Whether stairs or small sections are involved
- Access to the home (including parking and furniture load)
- The number of coats needed for an even finish
This explains why two 50m² jobs may differ significantly in total cost.
One of the primary determinants of this cost is the type of coating chosen. The finish not only affects the final appearance of the floor but also its durability and maintenance requirements. Two of the most popular coatings in the Australian market are solvent-based and water-based polyurethanes and their details are below:
Solvent-Based Polyurethane
This type of coating is known for its high durability and glossy finish. It’s a favourite among homeowners who desire a high-shine, reflective surface that accentuates the natural grain of the wood. On average, sanding and polishing with a solvent-based polyurethane will cost between $25 and $35 per square metre. While it offers a stunning finish, it’s worth noting that solvent-based polyurethanes tend to have a stronger odour during application, which dissipates once dried.
When Solvent-Based Is the Better Choice
Solvent-based coatings often perform better in:
- Older homes with deep, rich timbers
- High-traffic areas requiring greater durability
- Spaces where a bold, glossy finish is part of the design
This finish also tends to hide imperfections less effectively, so proper sanding is crucial.
Water-Based Polyurethane
A more environmentally friendly option, water-based polyurethanes are low in volatile organic compounds (VOCs), making them a safer choice for households, especially those with children or pets. They provide a clear finish, preserving the natural look of the wood. The cost for sanding and polishing with a water-based polyurethane typically ranges from $30 to $40 per square metre. Besides being eco-friendly, they also dry faster and have a milder odour compared to their solvent-based counterparts.
Water-based finishes have grown in popularity throughout Sydney due to their modern aesthetic and quicker turnaround time. They also experience far less yellowing over the years, making them the preferred option for lighter timbers such as Blackbutt and Oak.
Factors Affecting Cost
Understanding the intricacies of floor sanding costs also requires a deep dive into the various factors that influence the final price. While a ballpark figure can be helpful, it’s the nuances of each project that determine the actual expenses. Here’s a comprehensive breakdown of how various factors determine the final price:
1. Size of the Space
The area slated for sanding is a significant cost influencer. Typically, larger spaces can offer a cost-benefit. For instance, while sanding a 20m² room might cost around $600 (at $30 per square metre), a more expansive 100m² area might be quoted at $2,500, effectively reducing the rate to $25 per square metre. This economy of scale is something homeowners with larger spaces can leverage.
Homes with many small rooms often cost more per metre than open-plan spaces. Detailed edging along skirting boards is one of the most labour-intensive parts of the job, and properties with multiple narrow entryways or built-in cabinetry increase this time significantly.
2. Type of Wood
Different timbers come with varied sanding costs. Common Australian woods like oak might cost around $30 per square metre to sand and refinish, while cherry, being slightly harder, could push the cost to $35 per square metre. Exotic or imported woods, due to their rarity or unique properties, might command prices upwards of $40 per square metre.
Woods such as Spotted Gum and Brushbox are also common across NSW and may require additional sanding stages to ensure a consistent finish. The hardness of the timber directly impacts the longevity of the coating, which is why professionals consider timber type when recommending the appropriate number of coats.
3. Refinishing Method
The battle between traditional and dustless refinishing also affects the price. Traditional sanding, while thorough, generates a lot of dust and might cost around $25 per square metre. In contrast, dustless refinishing, which minimises airborne particles, could be priced slightly higher, say $35 per square metre, given the specialised equipment and cleaner process.
Some homeowners choose dustless sanding specifically when renovating while living in the home. This method can significantly reduce airborne dust, making it ideal for those with allergies or sensitive household members.
4. Labor Costs
The expertise of the professionals hired can significantly sway labour costs. Experienced professionals with a robust portfolio might charge around $30 to $40 per hour, while newer entrants to the field might offer rates of $20 to $25 per hour. Additionally, metropolitan areas, with their higher living costs, might see labour rates 10-15% higher than more rural regions.
Labour also includes travel time, material handling, and setup. Professional-grade sanding machines require careful calibration, and more experienced tradespeople typically produce a more even finish with fewer visible marks or swirls.
5. Additional Costs
There are always potential add-ons to consider. For instance, furniture relocation might add an extra $5 per square metre to the bill. Removing old flooring or carpeting on top of the hardwood could introduce another $10 per square metre. Addressing minor damages or securing loose floorboards might range from $50 to $100 per repair. And if you’re opting for traditional sanding, factor in another $50 to $100 for post-sanding cleanup.
Another commonly overlooked factor is stain removal. If the timber has dark water damage, pet stains, or ink marks, additional sanding or targeted bleaching may be required — each of which affects pricing.
Real Examples of How These Factors Affect a Final Quote
To help illustrate how these cost factors work together, here are practical examples based on the most common project types:
Small Bedroom (12–15m²)
A standard bedroom in good condition usually sits at the lower end of the cost scale. With minimal repairs and a straightforward layout, most homeowners fall between $350 and $550, depending on coating choice. Water-based finishes add a slight premium, but the faster drying time often appeals to households.
Medium Living Area (25–40m²)
Spaces like lounges or combined dining areas often include more edging and detailed preparation. If older coatings need removal or the floor has moderate scratching, the range typically increases to $800–$1,400. Homes with pets or high foot traffic may also require additional gap filling or board securing.
Whole-Home Projects (70–120m²)
Larger sanding projects benefit from improved cost efficiency per square metre but require more labour overall. Full-home refinishing commonly ranges between $2,200 and $4,500, depending on the timber type, coating system, and how much furniture or preparation is required before starting.
These examples help set realistic expectations so homeowners may better understand where their project might sit within the broader price range.
Types of Finishes and Their Costs
The finish on a hardwood floor doesn’t just dictate its final appearance; it also plays a pivotal role in the floor’s durability and maintenance. With a myriad of finishes available in the market, understanding each type and its associated costs is crucial for homeowners. Here’s a detailed exploration:
Clear Finish
Gloss Finish
For those seeking a shiny, reflective surface, the gloss finish is the go-to option. It offers a luxurious sheen, making the floor a centrepiece of the room though it might show scratches more prominently. The premium appearance of a gloss finish comes with a price tag of approximately $40 to $45 per square metre.
Satin & Matte Finishes: The New Standard
In modern Australian homes, satin and matte finishes have overtaken gloss as the preferred choice. They hide imperfections more effectively, suit contemporary interior design, and create a more natural timber appearance.
Types of Hardwood Flooring and Their Refinishing Costs
As you consider the finish, bear in mind that the type of wood also plays a significant role in both aesthetics and financial considerations. This time, let’s get into some popular hardwood flooring types, diving into their intricacies and how they resonate with the costs:
1. Oak
Oak remains a classic choice for hardwood flooring, known for its resilience and adaptable appearance. Its distinct grain patterns can range from straight and tight to more intricate and swirling. The cost of refinishing oak floors typically falls within an average range of $20 to $25 per square meter. Oak’s versatility extends to staining options, allowing you to tailor the colour to your preferences.
2. Jarrah
Native to Australia, Jarrah hardwood boasts a deep reddish-brown hue that matures over time. Its unique colour variation, coupled with natural termite resistance, makes it sought-after. Refinishing Jarrah floors is slightly more intricate due to the wood’s density and rich colour, resulting in costs ranging from $25 to $30 per square meter. However, the investment translates into a floor radiating warmth and character.
3. Blackbutt
Blackbutt, another Australian native, is celebrated for its light appearance and versatility. Subtle grain patterns and neutral tones make it a canvas for various design styles. Refinishing Blackbutt floors typically ranges from $20 to $25 per square meter, thanks to its straightforward process. The lighter colour allows for diverse stain options, enabling you to tailor the aesthetics to your home.
4. Teak
Teak hardwood stands out for its durability and moisture resistance, often seen in bathrooms and kitchens. With a golden-brown hue and distinct grain, teak floors bring exotic charm indoors. Refinishing teak requires nuanced attention due to its natural oils, with costs ranging from $30 to $35 per square meter. The expertise invested translates into both stunning visuals and durability.
Other popular timber species in NSW include:
- Tasmanian Oak: Light, versatile, and easy to sand
- Spotted Gum: Known for variation in colour tones
- Pine: Softer, requiring careful sanding techniques
Each timber type influences the sanding sequence used, which affects time and cost.
Wood Type and Traits Affecting the Cost
On top of the usual costs for the sanding, your chosen wood also contributes to the overall cost. As each hardwood type contributes distinct traits to your home’s personality, these attributes also play a pivotal role in the refinishing process and costs:
- Grain Patterns: Intricate patterns may necessitate meticulous sanding for an even finish.
- Wood Hardness: Harder woods, such as Jarrah, may require additional sanding and expertise.
- Colour Variation: Woods like Jarrah with colour variation might demand extra attention during staining.
- Oil Content: Woods with natural oils, like teak, might necessitate specialized finishing techniques.
- Stain Flexibility: The ability to customize staining options can influence refinishing costs.
Timbers with high oil content, such as Teak, may reject certain coatings unless properly prepared. This is why professionals test small sections before applying coats to the entire floor.
Navigating Investment for Business Spaces
While the focus on residential floor sanding is paramount, the realm of floor sanding extends to commercial spaces as well. Just as homes reflect the personalities of their occupants, commercial establishments convey the ethos of their businesses and understanding the nuances of commercial floor sanding costs is essential for businesses seeking to create an inviting and professional environment that resonates with clients and employees alike.
Commercial properties may also require fast-curing coatings to minimise downtime. Some businesses opt for commercial-grade water-based polyurethanes with enhanced scratch resistance, which can alter the cost per metre.
Factors Influencing Commercial Floor Sanding Costs
- Square Footage: The size of the commercial space directly impacts the cost. Larger areas require more materials, labour, and time, leading to increased expenses. On average, commercial floor sanding costs range from $30 to $40 per square meter.
- Type of Flooring: Commercial spaces often feature a variety of flooring types, from hardwood to concrete. The type of flooring and its condition influence the complexity of the sanding process and, consequently, the cost.
- Traffic Levels: Businesses experience varying degrees of foot traffic, impacting the wear and tear on floors. High-traffic areas might require more frequent maintenance, affecting refinishing frequency and cost.
- Customization and Branding: Commercial spaces often incorporate custom designs, logos, or patterns into the flooring. The complexity of these designs can influence the cost of sanding and refinishing. Business
- Downtime: The timing of floor sanding plays a role in cost considerations. Businesses might need to schedule sanding during off-hours to minimize disruption, potentially impacting labour costs.
- Materials and Finish: Commercial spaces might opt for specialized finishes that enhance durability and aesthetics. The choice of materials and finishes contributes to the overall cost.

Why Proper Floor Maintenance Matters
Beyond aesthetics, regular floor maintenance is crucial for preserving property value. Well-maintained floors are resistant to wear and tear, ensuring they remain a home’s centrepiece for years. Plus, with proper care post-sanding, you can ensure longevity and a lasting shine.
A well-maintained floor not only lasts longer but also reduces the need for full re-sanding. In many cases, a simple re-coat may extend the life of the floor by several years at a fraction of the cost.
