Your Complete Guide to Pressure Washing Costs in 2026

Pressure washing is one of those jobs where the before-and-after can be seriously satisfying. The less satisfying part? Working out what it’s going to cost.

So, how much does pressure washing cost?

In Australia, many residential jobs fall somewhere between $150 and $500, although the final price can vary depending on the surface, size, access, and how much dirt, mould, oil, or staining needs to be removed.

A small patio with light grime is one thing. A steep roof or heavily stained driveway is another.

This guide breaks down typical 2026 Australian pressure washing costs, the factors that affect pricing, and when DIY cleaning may make more sense than hiring a professional.

What Factors Determine the Cost of Pressure Washing?

There is no neat one-price-fits-all answer. Two areas of the same size can take very different amounts of time and effort to clean.

Here are some of the main factors that can affect the pricing.

1. Surface Type. Concrete is usually straightforward to pressure clean, while timber, painted surfaces, render, roofing, and other delicate materials need more care. Some may require soft washing rather than high pressure.
2. Size of the Area. More square metres generally means more labour, water, and cleaning product. Larger jobs may attract a lower per-square-metre rate, but the total cost will still be higher.
3. Condition. A light layer of dust is quick work. Years of mould, algae, oil, tyre marks, grease or grime may need chemical treatment, longer dwell times, and multiple passes.
4. Access. Stairs, narrow side passages, steep slopes, height, limited water access, and awkward building layouts can all add more time to the job.
5. Location. Labour, travel, parking, and call-out costs vary across Australia. A contractor travelling to a rural property may price differently from someone working locally in a metropolitan area.
6. Extra Services. Gutter cleaning, soft washing, stain treatment, sealing, or cleaning several areas at once can change the final quote.

So, how much does pressure washing cost in Australia? The safest answer is to use general price ranges for budgeting, then get an actual quote once the contractor can see what they are dealing with.

Average Pressure Washing Costs by Surface and Size

Australian pressure cleaning is commonly priced by the square metre, by the hour, or as a fixed job.

As a broad 2026 guide, general pressure cleaning may cost around $3-5 per square metre, or roughly $120-165 per hour.

• Driveways. Around $150-350 for many residential driveways. Large areas, oil stains, heavy mould, or difficult access can push the price higher.
• Patios and Decks. Roughly $150-300 depending on the size, material, condition, and cleaning method. Timber may need gentler pressure than concrete or paving.
• House Exteriors. Around $200-600 as a ballpark, with larger multi-storey homes or difficult surfaces costing more.
• Roof Cleaning. Often around $350-850+, depending on roof size, pitch, access, material, and contamination. Many roofs are better suited to soft washing than aggressive pressure cleaning.
• Commercial Areas. Straightforward hard-surface cleaning may start around $3-5 per square metre, while detailed, heavily contaminated, difficult-access, or specialised commercial work can rise considerably.

If you’re specifically wondering “How much does driveway pressure washing cost”, around $150-350 gives you a reasonable starting point for an average residential job.

Still, take the numbers with a grain of salt. A spotless 30m² courtyard and a grease-covered 30m² workshop floor may occupy the same space on a tape measure, but they certainly won’t clean the same way!

Residential vs Commercial Pressure Washing: What’s the Difference?

Residential pressure washing usually involves smaller areas such as driveways, paths, patios, fences, and house exteriors.

The equipment can be relatively compact, and most jobs can be completed without the logistical juggling that comes with large commercial sites. Commercial pressure washing is another story.

Businesses may need to clean

• Car parks
• Warehouses
• Loading areas
• Shopfronts
• Workshops
• Commercial paths
• Large concrete areas
• Machinery zones

Size alone can change the equipment required. Commercial operators often need pressure washers with higher litres per minute (LPM), longer hoses, surface cleaners, larger water supplies, or skid-mounted systems so they can cover more ground efficiently.

There may also be tighter operating windows, public safety requirements, grease or chemical contamination, and the need to work around staff, customers, vehicles, or equipment.

DIY vs Professional Pressure Washing: Which is Better for Your Budget?

Hiring a professional costs more upfront. Doing it yourself costs less… sometimes.

For occasional jobs, hiring or renting equipment can avoid the cost of buying a pressure washer, hoses, nozzles, surface cleaners, chemicals, and safety gear.

But regular cleaning changes the maths.

Homeowners with large outdoor areas, facility teams, contractors, and businesses may get better long-term value from owning equipment. NWC Softwash’s 24LPM Pressure Washer Skid, for example, is designed for users who need higher water flow and professional cleaning performance.

Before buying, factor in

• Pressure washer or skid
• Hoses and fittings
• Nozzles
• Surface cleaners
• Cleaning chemicals
• Fuel or electricity
• Servicing and maintenance
• Storage

Professional cleaning has its own advantages. You are paying for labour, equipment, experience, and someone who already knows that full pressure on old paint is a spectacularly bad idea.

For small, straightforward areas, DIY can make sense. For roofs, large commercial jobs, difficult stains, height work, or delicate surfaces, paying someone with the right equipment and experience may save money in the long run.

Tips to Save Money on Pressure Washing Services

You don’t necessarily need to hunt down the cheapest contractor in town to spend less.

A few smarter moves can help.

• Get a few different quotes: Compare what is included rather than looking at the final number alone.
• Bundle areas together: Cleaning the driveway, patio, and paths in one visit may be better value than booking three separate jobs.
• Clear the area beforehand: Moving outdoor furniture, pot plants, vehicles, and other obstacles can reduce setup time.
• Keep up with maintenance: Regular cleaning can prevent mould, algae, oil, and grime from reaching the “bring in the cavalry” stage.
• Buy equipment if you clean regularly: For businesses or serious DIY users, ownership can reduce repeat service costs.
• Learn proper technique: NWC Softwash training workshops can help professional cleaners and DIY users understand equipment, chemicals, surface safety, and efficient cleaning methods.

And remember, the cheapest clean is not much of a bargain if damaged paint, timber, render, or paving needs repairing afterwards.

Why Choose NWC Softwash for Pressure Washing Solutions?

If you’d rather build your own cleaning setup, NWC Softwash stocks equipment for homeowners, DIYers, contractors, and professional cleaners.

The range covers high-pressure cleaners, pressure washer skids, hoses, reels, nozzles, lances, surface cleaners, fittings, soft washing equipment, and cleaning chemicals. That means you can put together a setup that suits the work you actually plan to do, rather than buying bits and pieces that don’t quite work together.

The right accessories can also make a big difference. A surface cleaner can speed up large concrete jobs, while the right nozzle gives you more control over how much force reaches the surface.
