Pressure Washing in Whangarei and throughout Northland
What is Pressure Washing?
Pressure washing is a specialised cleaning technique that uses high-pressure water to remove dirt, grime, mould, algae, and other nasties from various surfaces.
Unlike traditional cleaning methods, pressure washing can tackle tough stains and build-ups efficiently. It's particularly suitable for hard surfaces like concrete, bricks, and metals, making it an ideal choice for cleaning driveways, sidewalks and carparks.
Benefits of Pressure Washing
- Pressure washing can remove stubborn stains, and tricky grime to brighten surfaces that other cleaning methods can't, ensuring a thorough clean.
- The process provides a satisfying before and after because the difference is usually extreme.
- Pressure washing enhances the look of an area which makes you feel happier. Plus, it makes the areas washed look well-maintained to impress the paints of visitors and your neighbours.
- We use eco-friendly detergents when we pressure wash that are safe for the environment, ensuring a sustainable cleaning process.

Frequently Asked Questions
Is hot water blasting suitable for food prep or hygiene areas?
Yes. It's perfect for sanitising areas like kitchens, butchery loading docks, supermarket forecourts, and cafes. It removes fats and bacteria while leaving no residues behind.
Can you remove chewing gum safely?
Yes. We soften and lift gum using heated water and specialised gum removal tools. This avoids gouging or damaging the concrete surface, unlike some aggressive cold blasting methods.
Do you use chemicals?
No. Hot water alone does the heavy lifting. This means no chemical runoff, no residue, and no harm to nearby vegetation. It's also ideal for sensitive environments where chemical use is restricted.
What surfaces can you clean using hot water?
We clean workshop floors, car parks, public walkways, food courts, factory yards, and building exteriors. The method is suitable for concrete, asphalt, tiles, and metal — and we adjust pressure and temperature based on your surface type.
How is it different from regular water blasting?
Traditional water blasting relies solely on pressure. Hot water blasting combines pressure with heat, which allows us to break down tough contaminants faster and more safely — especially on greasy or oily surfaces. It’s also gentler on some materials when used correctly.
Do I need to move anything off the surface beforehand?
If possible, we recommend clearing the area of vehicles, planters, or outdoor furniture to allow for a more thorough clean. If there are any access issues or large items you need help with, just let us know ahead of time.
Will this make my driveway or paths less slippery?
Yes. Our cleaning process removes organic build-up like moss and algae that makes surfaces slippery. After we’re done, your concrete will be safer to walk or drive on — particularly useful in shaded zones or before winter.
How long will my concrete stay clean after washing?
The post-wash mould treatment significantly slows down regrowth, so most surfaces stay clean for 6–12 months. Shady or damp areas may need more frequent treatment. Our goal is not just to clean the surface but to help it stay that way for longer.
Is it safe for coloured or decorative concrete?
Absolutely. We adjust the pressure, cleaning method, and detergent type based on your surface. This ensures decorative, stamped, or coloured finishes are not damaged. We’ve cleaned everything from exposed aggregate to dyed driveways with excellent results.
Will this remove black mould, moss, and tyre marks?
Yes. Our high-powered concrete-safe process is effective at lifting black mould, green algae, moss, and even stubborn tyre marks. For oil stains or heavy discolouration, we use specialised degreasers where needed. You’ll see a brighter, more even surface with improved safety and presentation.
How long does it take to pressure wash an area?
The duration varies based on the size of the specific areas being cleaned. Bumpy concrete takes a longer than smooth concrete. If the concrete does not have a fall for the water to drain it can also take longer.
The dirtier the concrete the longer it takes. Ditto if the water pressure is not great.
Pressure washing vs. soft washing: Which is better for houses?
Pressure washing is suitable for tougher materials like driveways and sidewalks, while soft washing is better for delicate surfaces like wood, cladding and painted walls.
What’s the difference between pressure washing and soft washing?
Pressure washing uses high-pressure water to blast away grime, while soft washing relies on low-pressure water and specialised detergents. Soft washing is safer for painted surfaces and materials like stucco and wood.
What chemicals are used for pressure washing?
We use biodegradable detergents that effectively break down contaminants without harming your property or the environment.
