Deck Cleaning
Professional Pressure Cleaning Specialists | Sunshine Coast
Surface Co. provides professional timber deck cleaning and restoration services across the Sunshine Coast using specialised pressure cleaning techniques designed specifically for timber surfaces. Deck cleaning removes years of grey weathering, mould, algae, and dirt buildup, restoring timber to its natural colour and preparing it for oiling or sealing. Our controlled pressure washing approach delivers commercial-quality results while protecting your deck from the splintering, grain raising, and damage that inexperienced or DIY pressure cleaning can cause.
Our Method: Combined Approach
Deck cleaning requires a specialised combination of soft washing and controlled pressure cleaning. We first apply timber-safe cleaning solutions at low pressure to break down mould and organic growth, then use carefully controlled pressure washing to restore the timber without causing damage. Pressure settings are adjusted based on timber type (hardwood vs pine), age, and condition. This balanced approach achieves professional restoration results while protecting the timber from the damage caused by excessive pressure or aggressive techniques.

Safety & Quality Assurance
Frequently Asked Questions
Will pressure washing damage my timber deck?
Not when done correctly with proper equipment and technique. Damage occurs when inexperienced operators use too much pressure, work across the grain, or use unsuitable equipment. We use controlled pressure appropriate for your timber type, work with the grain direction, and combine pressure cleaning with chemical pre-treatment to achieve safe, professional results. This is why hiring experienced deck cleaning specialists matters.
Can you clean really old, grey weathered decks?
Yes, this is our specialty. Even severely weathered decks can be restored to near-original colour with professional pressure cleaning. The grey appearance is weathered timber fibres on the surface - once removed, the natural timber colour underneath is revealed. Very old or damaged decks may have some permanent discolouration, but results are typically excellent.
Should I oil my deck after cleaning, and when?
Yes, absolutely. Deck oiling or sealing after cleaning is essential to protect your investment and maintain the restored appearance. We recommend oiling 2-7 days after cleaning once the timber has dried but is still receptive. Delaying too long (more than 2-3 weeks) allows weathering to restart. We'll provide specific timing advice based on weather conditions and your timber type.
Do you clean composite or Trex decking?
Yes. Composite decking requires lower pressure than timber but still benefits from professional cleaning to remove mould, dirt, and staining. We adjust our technique specifically for composite materials to deliver safe, effective results without surface damage. Composite decking doesn't require oiling but should be cleaned regularly for appearance and safety.
How long does deck cleaning take?
Most residential decks take 2-4 hours depending on size and condition. Heavily weathered or stained decks may require additional time for proper restoration. Large multi-level decks can take a full day. We'll provide an accurate time estimate during your free quote after assessing your specific deck.
How often should timber decks be cleaned?
We recommend cleaning and re-oiling every 12-18 months for best results on the Sunshine Coast. This prevents buildup of organic growth and maintains timber protection. Neglected decks that go years without maintenance require more intensive restoration and may have suffered damage that could have been prevented with regular care.
