We use controlled pressure washing with fan nozzles to clean effectively without splintering wood fibres, combined with specialist decking cleaners that break down slippery biological growth at the root level. ### Who It's For This service is for any homeowner in Milton Keynes with a timber or composite deck that has become slippery, discoloured or weathered. Whether you have a small raised deck, a wraparound garden platform or composite decking boards, our service restores the surface safely. It is especially important for families with children and elderly residents, where slippery decking presents a genuine slip hazard. ### When You Need It Spring is the ideal time to clean decking — preparing your outdoor space for summer use after winter weathering. However, we clean decking year-round. Signs it needs attention include a green or black surface film, visible algae growth, slippery patches when wet, grey discolouration on timber, or splinters forming on neglected boards. ### Why Professional Algae-covered decking is a serious slip hazard — one of the most common causes of garden injuries. Beyond safety, neglected decking deteriorates rapidly. Moisture-retaining algae accelerates timber rot, warping and splitting. Professional cleaning removes the hazard, restores the appearance and extends the life of your decking investment. ## The Hidden Dangers of Dirty Decking 1 Algae-covered decking is one of the leading causes of garden slip injuries in the UK. The biological film that forms on timber and composite surfaces becomes incredibly slippery when wet — and in the British climate, that means most of the year. 2 Moss and algae hold moisture against timber fibres, accelerating the rot process. Boards that could last 15–20 years with proper maintenance may need replacing within 5–7 years if left uncleaned. 3 Grey, weathered decking drags down the appearance of your entire garden. What should be an attractive outdoor living space becomes an area you avoid — a wasted investment that detracts from your home. 4 Composite decking is not immune. While it resists rot, it still becomes colonised by algae and develops slippery biofilm. Without cleaning, the textured anti-slip surface becomes ineffective. Professional decking cleaning eliminates the slip hazard and restores your outdoor space to its full potential. How It Works ## Our 5-Step Process 1 ### Assessment We inspect your decking to identify the material type, condition and level of contamination, then select the appropriate cleaning method and solution. 2 ### Pre-Treatment A specialist decking cleaner is applied to break down algae, moss and biological growth. This is left to dwell for optimal results. 3 ### Controlled Pressure Washing Using wide fan nozzles at carefully calibrated pressure, we clean each board along the grain to remove all contamination without damaging the surface. 4 ### Edge & Detail Work Railings, steps, edges and gaps between boards are cleaned by hand to ensure a thorough, even result across the entire deck. 5 ### Optional Treatment For timber decking, we offer oil or stain application to restore colour and provide weather protection. We advise on the best product for your wood type. Why Choose Us ## The Benefits of Professional Decking Cleaning & Restoration ### Eliminates Slip Hazards Removing algae and biofilm restores the safe, non-slip surface of your decking — protecting your family from dangerous garden falls. ### Restores Natural Colour Professional cleaning reveals the warm, natural tones hidden beneath years of grey weathering and green algae — transforming your outdoor space. ### Extends Decking Lifespan Removing moisture-retaining growth prevents rot, warping and splitting, adding years of life to your timber or composite boards. ### Improves Garden Appeal Clean decking becomes the focal point of your garden again — an inviting space for entertaining, relaxing and family time. ### Safe for All Materials Our techniques are calibrated for timber softwood, hardwood and composite decking. We never use excessive pressure that could damage surfaces. ### Optional Protection Post-cleaning oil or stain treatment nourishes timber, restores colour and provides months of weather protection. Expert Guide ## Expert Decking Restoration Guide Milton Keynes homes commonly feature softwood decking (typically pressure-treated pine) installed during the building phase or added later as a garden improvement. The region's mix of clay and sandy soils creates varying drainage conditions that affect how quickly decking deteriorates. Composite decking, increasingly popular on newer estates, requires a different approach. While it does not rot like timber, composite boards develop a biofilm of algae that makes the surface dangerously slippery. Our cleaning removes this biofilm and restores the textured surface grip that is built into the board design. For timber decking, we recommend cleaning followed by an appropriate oil or stain treatment. Oil penetrates the wood grain, nourishing the fibres from within and providing water-repellent protection. Stains add colour while forming a surface barrier against UV damage and moisture. We advise on the best option based on your wood type and desired finish.
