How Much Does Pressure Cleaning Cost?

Pressure cleaning is one of the most effective ways to restore the look of your home’s exterior surfaces. Over time, dirt, mould, mildew, and stains build up on driveways, patios, decking, roofs, and walls, leaving them looking tired and worn. A professional pressure clean can instantly transform these areas, improving curb appeal and protecting surfaces from long-term damage. For example, removing moss or algae from pathways not only improves appearance but also makes them safer by reducing slip hazards. Pressure cleaning is also highly versatile, capable of tackling everything from concrete driveways and brick walls to timber decking and tiled roofs.

The cost of pressure cleaning in Australia varies depending on the size of the area, the type of surface being cleaned, and the condition of the material. A simple driveway clean may cost a few hundred dollars, while a full exterior house wash could run into the thousands. Factors such as accessibility, water usage, and whether special treatments are needed (for stains, oil, or mould) can also affect the final price. Hiring a professional ensures the correct pressure and cleaning techniques are used for each surface, avoiding the risk of damage that comes with DIY high-pressure washers.

How much does pressure cleaning cost?

On average, pressure cleaning in Australia costs between $150 and $600 for smaller jobs, such as a patio or driveway, while larger jobs like a full house exterior can range from $700 to $2,000+. Rates are typically calculated per square metre, with prices averaging $3 to $10 per m², depending on surface type and condition.

What Affects the Cost of Pressure Cleaning?

The size of the area to be cleaned is the most obvious factor. Larger surfaces, such as long driveways, patios, or full house exteriors, will cost more simply because they require more time, water, and labour. Pressure cleaning is often charged by the square metre, so the bigger the job, the higher the overall price.

The type of surface also influences cost. Concrete and brick are usually straightforward to clean, while more delicate surfaces like timber decking, tiled roofs, or painted walls require lower pressure settings and more careful handling. These surfaces may take longer to clean, increasing labour costs.

The condition of the surface plays a big role too. Light dirt and dust are quick to wash away, but heavy build-up of mould, moss, algae, or oil stains can require pre-treatment with chemicals or multiple passes with the pressure washer, driving up the cost.

Accessibility can also affect pricing. Flat, open driveways are easier and cheaper to clean than high, steep, or difficult-to-reach roofs. Jobs that require ladders, scaffolding, or safety equipment will add to the final bill.

Finally, location and labour rates make a difference. In metropolitan areas where demand for professional cleaners is higher, rates are generally more expensive than in regional areas.

In summary, pressure cleaning costs depend on:

• Size of the area

• Type of surface (concrete, timber, brick, roof tiles, etc.)

• Condition of the surface (light dirt vs heavy stains or mould)

• Accessibility of the area

• Labour rates and location

Average Cost of Pressure Cleaning in Australia

Here’s what you can generally expect when getting pressure cleaning done in Australia:

• A common rate is $3 to $5 per m² for standard surface cleaning.

• Hourly rates often fall between $120 and $165 per hour.

• Some sources give a broader range of $3 to $10 per m², depending on surface type, access, and condition.

• Smaller jobs (1–30 m²) typically cost $150, while 100 m² may go for $325 under standard conditions.

• For typical surfaces:

• A standard driveway clean might cost around $200
• Exterior home walls might cost about $350 
• Roof cleaning jobs often range between $150 and $350, depending on pitch and material.

Pressure Cleaning Costs by Surface Type

• Concrete / driveways / paths
  These are the most common and straightforward surfaces to clean. Expect rates in the lower end of the per-m² scale (e.g. $3 to $6 per m²) for basic concrete.

• House exteriors / walls
  Cleaning walls involves vertical surfaces, windows, and potential obstacles. The cost is usually higher—around $5 to $10+ per m², depending on the wall material and condition.

• Roof surfaces / tiles
  Roof cleaning is more complex due to safety, access and fragility of tiles. Repairs or replacements may be needed. Rates might range $6 to $12+ per m².

• Timber decking / wood surfaces
  Timber is delicate and requires gentler pressure, which slows work. Prices are often in the mid to higher band, depending on wear, stains and algae.

• Pavers / natural stone
  Natural stone or pavers can require special cleaners and lower pressure to avoid damage, adding to cost.

Hidden & Additional Costs

When planning for pressure cleaning, it’s important to keep in mind the extra costs that can come up beyond the basic square metre rate. Surfaces that are heavily stained with oil, rust, mould or graffiti may require chemical treatments or specialised detergents, which increase the overall price. If your property has high or difficult-to-access areas, the use of ladders, scaffolding or additional safety equipment may also add to the cost. Water usage and runoff management can be a factor, especially in regions with restrictions. Sometimes, pressure cleaning can reveal underlying issues such as cracked tiles, loose mortar or damaged paintwork, which may require additional repair work. You might also need to account for the cost of waste removal, as moss, dirt and other debris must be cleared away after cleaning. Finally, professionals may charge extra for protecting surrounding areas such as plants, windows or outdoor furniture to ensure they are not damaged during the cleaning process.

Benefits of Pressure Cleaning

The main advantage of pressure cleaning is the way it restores surfaces, leaving them looking clean, fresh and well maintained. By removing dirt, mould, moss and algae, pressure cleaning not only improves the appearance of outdoor areas but also extends the lifespan of finishes by preventing long-term damage. It enhances safety by eliminating slippery growth on paths, driveways and decks, reducing the risk of accidents. A freshly cleaned property also boosts street appeal and overall property value, which can be especially beneficial if you’re preparing to sell. Compared to manual scrubbing, pressure cleaning is far more efficient, saving homeowners both time and effort while achieving a professional result.

How to Save on Pressure Cleaning Costs

There are several ways to keep pressure cleaning affordable without compromising on quality. One of the best strategies is to combine jobs—for example, having your driveway, patio and exterior walls cleaned in the same session—to reduce setup costs. Carrying out light maintenance between professional cleans, such as sweeping or rinsing with a garden hose, can also prevent heavy build-up and keep future costs down. Preparing your surfaces before the tradesperson arrives, by removing plants, furniture and loose debris, allows them to get started quickly and saves labour time. Always compare quotes from multiple cleaners to ensure you’re getting a fair price and clear inclusions. Finally, consider scheduling your job during off-peak periods, as you may be able to secure better rates when demand is lower.

Finding the Right Pressure Cleaning Specialist

While DIY pressure washers are available, professional pressure cleaning delivers far superior results and avoids the risk of damaging delicate surfaces. The right specialist will know how to adjust pressure settings for different materials—using stronger streams for concrete driveways and gentler techniques for timber decking or tiled roofs. They’ll also come equipped with commercial-grade machines, safety gear, and cleaning solutions to remove even the toughest stains.

When hiring a pressure cleaning specialist, always check that they are experienced, insured, and use the correct techniques for your property. Ask for a detailed written quote that explains what areas will be cleaned, whether detergents are included, and if waste removal is covered. Looking at past projects or customer reviews can give you confidence in their workmanship.
