Service Overview
Everything You Need to Know
What Is It
Decking cleaning and restoration is the professional removal of algae, moss, dirt and weathering from timber and composite decking boards, followed by optional treatments to restore colour and protect the surface. 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
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.
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.
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.
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
Assessment
We inspect your decking to identify the material type, condition and level of contamination, then select the appropriate cleaning method and solution.
Pre-Treatment
A specialist decking cleaner is applied to break down algae, moss and biological growth. This is left to dwell for optimal results.
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.
Edge & Detail Work
Railings, steps, edges and gaps between boards are cleaned by hand to ensure a thorough, even result across the entire deck.
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.

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.
