The driveway’s gone green. There’s a grey tide mark along the fence, and the paving by the back door is a slip risk after the first proper rain. You’ve been meaning to sort it for a year, and the weekend hire machine has started to look tempting.
High pressure cleaning Perth WA homeowners can book is a service that blasts dirt, algae and grime off hard surfaces with pressurised water, so driveways, paths and walls look clean again. Prices vary a lot by surface and size. Booking at the right time, and asking the right questions, saves more than haggling.
If you want a quote, our pressure cleaning Perth page covers what we offer. This article covers what the work includes, what Perth jobs tend to cost, and when to book.
What is high pressure cleaning?
Quick definitions first. High pressure cleaning refers to using a machine that forces water through a narrow nozzle at high force to lift dirt off a surface. Soft washing is a gentler method that uses lower pressure and a cleaning solution, and it suits delicate surfaces. Hardstand means any paved or concreted outdoor area, like a driveway or patio.
Our service page lists fences, windows, doors, tiles and driveways, and says the service suits other parts of a building too. It says chemical free detergents are used. It doesn’t list roofs, so if you want yours done, ask before you book.
What does it cover?
Most jobs fall into a few groups:
- Driveways, paths and patios.
- Exterior walls and fences.
- Tiles and paving.
- Windows and doors.
- Whole house exterior washes.
Pavers, exposed aggregate and rendered walls need lower pressure than plain concrete, so a good operator changes the setup for each surface. A blast that’s fine on a driveway can strip render or lift paver sand. Ask what they’ll use on yours.
What does it cost in Perth?
Prices shift with the size of the job, the surface and how dirty it is. Treat these as a guide, not a quote. According to What’s the Damage (2026), typical Perth prices look like this:
| Job | Typical price | Usual range |
| Driveway | $260 | $160 to $420 |
| Roof, standard home | $735 | $315 to $1,375 |
| House exterior, single storey | $440 | $260 to $735 |
| House exterior, double storey | $790 | $470 to $1,150 |
| Hourly rate | $68 | $42 to $105 |
Nationally, Airtasker (2025) says most companies charge $1.50 to $5 per square metre, with an average of about $3. That’s a useful sanity check for larger areas.
What pushes a quote up? Heavy mould or lichen, bore water staining, a second storey, delicate surfaces and awkward access. A site without a nearby tap takes longer too. The same guide notes that pavers, exposed aggregate and rendered walls need more time than plain concrete.
Gutters Perth doesn’t publish prices, so I haven’t made any up. Ask for a written quote that lists the areas, the method and the price.
When should you book?
There’s no single right month. But some moments are smarter than others:
- Before painting. Paint won’t stick to a dirty or flaking surface.
- Before you sell or list a rental. Clean paths and a clean driveway lift the first impression.
- After winter, when algae and mould show up on shaded paving.
- After a big storm that leaves mud or leaf stain.
- Before gutter or roof work, so the surfaces below are clean when the job’s done.
Think about the order, too. Gutters shed dirt. If you clean the paving first and the gutters later, you’ll rinse debris onto clean surfaces. Our gutter cleaning and guttering pages explain that side of things, and so does our roof repair page if the roof needs work as well.
The wastewater rule people forget
Pressure cleaning makes dirty water. Where it goes matters. According to the Department of Water and Environmental Regulation (2025), the stormwater system is meant only for uncontaminated rain runoff, and it isn’t designed to carry wastewater. The department’s fact sheet says even washing with water alone or with biodegradable products still produces wastewater that isn’t safe to discharge into the environment.
That fact sheet is written for light industry, not for homeowners. Still, it makes the principle clear. Ask any cleaner how they’ll handle runoff, and whether they keep it out of the street drain and the garden beds.
Questions to ask before you book
- What pressure will you use on my surfaces?
- Do you cover roofs, or only hard surfaces?
- How will you manage the runoff?
- Is the quote written, with the areas and method listed?
- Are you insured?
- How long will the job take?
If a cleaner can’t answer the runoff question, think twice. It tells you how they work.
Should you hire a machine instead?
You can. Hire machines work. But a machine isn’t a technique. Too much pressure scars concrete, chips paint and blasts sand out of pavers. A 20 second mistake leaves a stripe you can see for years.
Honestly, for a small patio, DIY is fine. For a big driveway, a render wall or a two storey job, a professional usually makes more sense. The ladder risk alone is worth the fee.
The mistake that costs twice
Cleaning without fixing the cause. Green paving under a leaking downpipe will be green again by spring. Mould on a wall under a blocked gutter will return. Clean it, then fix what’s feeding it.
My view: book the clean after the repair, not before. You’ll only pay for it once.
FAQ
How much does pressure cleaning cost in Perth?
According to What’s the Damage (2026), a typical Perth driveway costs about $260, with a range of $160 to $420. Roofs and house exteriors cost more, so ask for a written quote.
Is high pressure cleaning safe for my driveway?
Usually, if the operator adjusts the pressure. Plain concrete takes it well. Pavers, exposed aggregate and render need a gentler approach.
Does high pressure cleaning remove mould and algae?
It can. Heavy mould or lichen may need extra treatment, which can add to the price.
Can wastewater go down the stormwater drain?
No. According to the Department of Water and Environmental Regulation (2025), the stormwater system is for clean rain runoff only. Ask your cleaner how they’ll manage runoff.
How often should I pressure clean?
It depends on shade, trees and moisture. Shaded paving often grows algae faster, so those areas may need it more often.
