High Pressure Cleaning Northern Beaches
Why outdoor surfaces on the Northern Beaches need more care
Life on the Northern Beaches is all about the outdoors. From BBQs in Balgowlah to beach days in Freshwater, our patios, driveways, fences, and pool surrounds get a workout. But the same coastal lifestyle that makes this area so popular also wears down outdoor surfaces fast.
Salt spray from the ocean settles on stone, timber, and tiles. Summer storms dump dirt and leaf litter into courtyards. Shaded spots in Seaforth and Forestville stay damp for weeks, letting moss and mould take hold. After just a season or two, paths become slippery, fences go green, and patios lose their colour. That’s why regular high pressure cleaning Northern Beaches services are more than cosmetic — they’re about safety and protecting your property.
Locals tell us the same thing: “I’ve scrubbed it, but it still looks the same.” That’s because deep stains and algae sit below the surface. Done properly, professional high pressure cleaning restores concrete, stone, timber, and tiles without damage — leaving your home safer and sharper.
What happens if you don’t pressure clean outdoor areas
It’s tempting to think high pressure cleaning is just about looks, but it actually prevents bigger problems:
-
Safety risks – Moss and algae make driveways, stairs, and pool surrounds dangerously slippery.
-
Permanent stains – Oil, mould, and dirt sink deeper into surfaces if left untreated.
-
Surface damage – Organic growth holds moisture that eats into stone, timber, and grout.
-
Reduced property value – A stained driveway or courtyard makes a home look neglected.
In short: leaving outdoor areas dirty isn’t just bad for street appeal — it can cost you in repairs, safety hazards, or even lower resale value.
How we clean surfaces on the Northern Beaches
Every surface reacts differently, so we don’t use a one-size-fits-all approach.
-
Concrete & stone – Can handle controlled high pressure to strip away years of stains, tyre marks, and grime.
-
Pavers & smooth tiles – Need even, consistent cleaning with rotary surface tools to prevent streaks.
-
Timber fences & decks – Require low pressure plus safe cleaning solutions to remove mould without splintering wood.
-
Sandstone & softer stone – Cleaned with reduced pressure and biocide treatments so the stone isn’t eroded.
-
Pool areas & patios – Treated for algae and then cleaned evenly, leaving them safe and slip-resistant.
We often pair high pressure cleaning with pre-treatments that kill mould and algae spores. This means areas stay cleaner for longer instead of regrowing a week later.
Our process
High pressure cleaning sounds simple — just blasting water at a surface — but in reality, it’s about using the right pressure, angle, and method for each job.
-
Concrete and stone can handle stronger jets that strip away stains quickly.
-
Pavers and brickwork often need a gentler approach to avoid damage.
-
Timber decks require lower pressure combined with cleaning solutions to lift dirt without splintering the wood.
We also treat surfaces for moss and mould so they stay cleaner for longer.
Real Projects: Case Studies
Seaforth: Sandstone stairs covered in moss
A family in Seaforth called after their sandstone entry stairs turned black with moss. Not only did the stairs look old, but they had also become dangerous when wet.
Sandstone is soft, so blasting it with full pressure can chip and erode the stone. Instead, we applied a moss-killing solution to penetrate deep into the pores. After dwell time, we used a wide spray fan on reduced pressure to rinse the surface clean.
The result: stairs that looked bright again, with restored grip and no damage to the sandstone. This approach keeps the stairs safe while protecting the stone’s natural character — a must for heritage-style homes on the Beaches.
Balgowlah: Timber fence green with mould
In Balgowlah, a boundary fence had gone green with lichen and algae. The homeowner had tried scrubbing it but only managed to smear the growth into the grain.
Timber needs careful handling. We first applied a gentle cleaning solution that loosened the lichen. Then, using low-pressure water and a wide spray pattern, we cleaned along the grain of the wood. This lifted the mould without leaving gouges or splinters.
Once dry, the fence looked almost new. We advised the owner to apply a protective sealant — something many locals choose to keep timber looking sharp after a clean.
Dee Why: Smooth tiled pool surrounds
A modern property in Dee Why had light-coloured tiles around the pool. Over time, algae had spread across the shaded edges, making the tiles dangerously slick.
Because these tiles were smooth and delicate, we couldn’t rely on raw pressure alone. We treated the area with an anti-algae solution, then used a rotary surface cleaner on a low setting to spread pressure evenly across the tiles. This prevented streaks and ensured the grout wasn’t damaged.
The pool surround came up spotless, and the family could safely enjoy their outdoor area again. It’s a perfect example of how local knowledge and the right equipment make all the difference.
