Professional Deck & Patio Cleaning on the Gold Coast

Your deck or patio should be an inviting outdoor space for entertaining, relaxing, and enjoying Queensland’s beautiful weather. But over time, the Gold Coast’s humid climate causes mould, mildew, and algae to turn beautiful timber grey and make stone surfaces slippery and stained.

Our professional deck and patio cleaning service safely restores all outdoor surfaces to their original beauty. We use specialized techniques tailored to each material type - gentle soft washing for timber, appropriate methods for composite, and high-pressure cleaning for stone and pavers.

Why Your Deck or Patio Needs Professional Cleaning

DIY pressure washing seems simple, but using the wrong pressure or technique can cause expensive damage:

  • Timber Damage: Too much pressure gouges wood fibers, creating a fuzzy, splintered surface that holds moisture and accelerates decay
  • Composite Issues: Harsh cleaning or high pressure can scratch composite surfaces and void warranties
  • Uneven Results: Inconsistent technique creates tiger striping and patchy cleaning
  • Safety Risks: Slippery surfaces when wet create dangerous fall hazards for family and guests
  • Shortened Lifespan: Improper cleaning damages protective finishes and accelerates weathering

Specialized Cleaning for Every Surface Type

Different outdoor surfaces require different cleaning approaches:

Timber Decking

We identify your timber species (Merbau, spotted gum, pine, etc.) and adjust our cleaning method accordingly. Soft wash cleaning with specialized timber treatments removes mould, grey weathering, and tannin stains without damaging wood fibers. Perfect preparation for oiling or staining.

Composite Decking

Composite materials from brands like NewTechWood, Trex, and Ekodeck require specific cleaning solutions that won’t damage the surface or void warranties. We use manufacturer-approved methods to remove stains, mould, and buildup safely.

Stone & Paver Patios

Natural stone, sandstone, bluestone, travertine, and concrete pavers can handle higher pressure cleaning. We remove embedded dirt, efflorescence, and organic growth while protecting joint sand and surface finishes.

Pool Decks

Pool surrounds require special attention to remove chlorine stains, calcium buildup, and the slippery biofilm that forms in wet areas. We clean all pool deck materials safely and effectively.

Restore Natural Timber Color

Timber decking turns grey from a combination of UV damage, dirt, and mould growth. Our restoration process uses specialized treatments including:

  • Mould Killing: Biocide treatments eliminate black mould spots
  • Deep Cleaning: Gentle cleaning removes dirt and organic matter
  • Timber Brightening: Oxalic acid treatment restores natural timber color by neutralizing tannins and removing grey weathering
  • Sealing Prep: Perfectly clean, open timber pores ready for oil or sealer application

Perfect Preparation for Oiling or Sealing

Planning to oil, stain, or seal your deck? Professional cleaning is essential for proper adhesion and longevity:

  • Removes dirt and mould that prevent penetration
  • Opens timber pores for maximum absorption
  • Creates a clean, uniform surface for even coating
  • Identifies any repairs needed before sealing
  • Extends the life of your oil or sealer investment

While we focus on cleaning, we can recommend experienced timber treatment professionals for sealing services.
