Safe & Damage-Free Deck Cleaning
Deck cleaning requires the right balance of pressure and technique. Too much pressure can damage timber and strip away its natural oils, while insufficient cleaning can leave behind dirt, mould, and algae.
At Spray & Wash, we use controlled pressure and suitable cleaning solutions to safely remove buildup without harming your decking. This approach helps maintain your deck’s condition and prevents premature ageing. For longer-lasting results, we also recommend a follow-up treatment to help control mould regrowth.
Exterior Cleaning Safety & Professional Standards
Exterior Cleaning, Water Blasting, and Chemical Washing involve potential risks if not handled correctly. Spray & Wash follows strict health and safety practices to ensure all work is carried out safely and responsibly.
Our team is fully trained and equipped to handle both residential and commercial projects, and can meet site-specific safety requirements when needed.
Our Deck Washing Process
At Spray & Wash, our expert deck washing process is tailored to restore the beauty and safety of your outdoor space.
We begin with a detailed inspection to assess your deck’s condition and identify problem areas like dirt, mildew, or algae buildup. A cleaning solution is then applied to loosen grime while being gentle on the environment. We carefully remove debris using state-of-the-art soft washing equipment, ensuring the correct pressure to clean thoroughly without damaging the deck surface. Finally, we rinse and dry the area, leaving your deck refreshed, slip-resistant, and ready for use or further maintenance like staining or sealing.
