Safe, Reliable & Long-Lasting Deck Cleaning Services for Homes, Strata & Businesses

Has your deck lost its appeal due to grime, weathering, or mould? At Clean Machine Sydney, we specialise in safe and thorough deck cleaning services in Sydney, catering to residential, strata, and commercial properties. Whether you have a hardwood timber deck, eco deck, or composite material, we provide tailored cleaning solutions to restore its beauty and maintain its longevity.

Decks are valuable outdoor features but are constantly exposed to the elements. Over time, rain, sun, foot traffic, and organic build-up can cause discolouration, slippery surfaces, and even rot or decay. Our expert team uses professional-grade equipment, eco-friendly cleaning agents, and low-pressure soft washing techniques to clean your deck without causing surface damage.

Why Deck Cleaning is Essential

A dirty or slippery deck isn’t just unattractive—it can also be dangerous and deteriorate faster if not properly maintained. Build-up of mould, algae, lichen, and mildew creates a hazardous walking surface, while grime and pollutants can degrade the timber or composite material.

By scheduling routine professional cleaning, you can:

• Extend the lifespan of your decking

• Improve safety by eliminating slippery spots

• Enhance visual appeal for entertaining or selling

• Prepare the surface for staining, sealing, or painting

Whether your deck is timber, composite, or modular, Clean Machine Sydney ensures it gets the right care to keep it functional and attractive.

What We Clean

We provide specialist deck cleaning for all deck types, including:

• Hardwood timber decks (Merbau, Spotted Gum, Blackbutt, etc.)

• Composite decking (ModWood, Trex, Futurewood)

• Eco decks and recycled plastic surfaces

• Modular and prefinished deck systems

Each material requires a specific approach—too much pressure can scar the wood or delaminate composite boards. That’s why we use gentle, controlled soft washing methods paired with surface-specific biodegradable cleaning agents that remove dirt and mould while protecting your deck’s integrity.

Our Sydney Deck Cleaning Services Include

1. Timber Deck Cleaning

We restore natural timber decks using soft washing techniques that preserve wood fibres and coatings. We remove grey weathering, mould, mildew, and embedded dirt without using excessive pressure that might splinter or scar the surface.

2. Composite & Eco Deck Washing

Composite materials may not rot like wood, but they can still harbour mould and grime in the surface texture. We clean composite decks without fading or damaging the protective outer shell, using safe, effective chemicals and gentle rinsing.

3. Mould & Algae Removal

Our targeted cleaning solutions remove green and black algae, moss, mildew, and lichen from your deck and surrounding structures. These not only make decks unsafe but also lead to faster material decay.

4. Deck Prep for Staining, Sealing & Painting

Planning to re-seal or paint your deck? We provide pre-treatment cleaning to remove old residue, dirt, and contaminants—ensuring a smooth, clean surface that absorbs new coatings evenly.

5. Cleaning of Surrounding Features

Our deck cleaning services can also include:

• Railing and balustrade cleaning

• Staircases and steps

• Outdoor furniture and decking surrounds

• Pergola and patio washing
