Devon Surface Care provide expert decking cleaning in Exeter, Barnstaple, Tiverton, Cullompton, Exmouth and Taunton, that removes moss, algae and slippery decking stains and restores the decking back to a smart, appealing outdoor space that can be enjoyed.

What is Decking Cleaning?

Decking cleaning is a specialist exterior service designed to restore, protect and prolong the life of your wooden or composite decking. Across Devon, decking has become a popular alternative to paving, extending outdoor dining areas and creating attractive garden features. However, without regular maintenance, algae, fungi and general surface dirt can quickly cause decking to become slippery, weathered and unsafe.

Professional deck cleaning removes harmful surface growth, restores colour and improves safety underfoot — especially during damp and wet weather.

Wood & Composite Deck Cleaning Specialists

We provide expert wood and composite deck cleaning services tailored to the material and condition of your decking.

• Professional deck cleaning in Devon for timber and composite surfaces

• 
  

• Removal of green algae growth, moss and surface grime

• 
  

• Safe cleaning methods that reduce the risk of splintering or surface damage

• 
  

• Restoration of weathered, grey decking to enhance natural colour

When first installed, decking looks fresh and vibrant. Over time, natural decomposition, algae growth and UV exposure can leave it grey, dull and potentially hazardous. Our decking cleaning specialists use proven methods to revitalise tired decking and restore its original appeal.

Our Deck Cleaning Process

Our structured decking cleaning process ensures long-lasting results and a safer outdoor space.

• Gentle pressure washing using a rotary lance for precision cleaning at every angle

• 
  

• Application of Blackwash biocidal treatment to inhibit algae and fungi regrowth

• 
  

• Careful sanding to create a smooth, splinter-free surface (where necessary) 

• 
  

• Inspection of screws, joints and boards during the cleaning stage

We gently pressure wash all surfaces and joints, removing dirt, algae and debris while minimising the risk of splintering. The use of a specialist rotary lance allows for a thorough clean without damaging the wood fibres. Once cleaned, the deck can safely get wet — but it will no longer be slippery.

Deck Restoration & Deep Cleaning Solutions

If your decking is heavily weathered, grey or structurally worn, our deck restoration services go beyond basic cleaning. We provide complete decking restoration and deep cleaning solutions to revitalise your outdoor space.

Surface growth and moisture not only affect appearance but can accelerate rot and structural deterioration. Regular cleaning and oiling helps prevent decay and maintain the strength and integrity of your deck.

Remove Moss, Algae & Slippery Decking Stains

One of the most common decking problems is slippery algae growth. In damp and shaded areas, green algae and fungi thrive, creating a hazardous surface.

• Effective removal of moss, algae and black stains

• 
  

• Elimination of slippery build-up to improve decking safety

• 
  

• Treatment to prevent rapid regrowth of organic matter

• 
  

• Improved appearance and traction in wet conditions

By removing the surface layer of dirt and algae, we restore a safer walking surface. Once properly cleaned and treated, your decking may still get wet — but it won’t remain dangerously slippery.

Decking Repairs, Oiling and Protection

After cleaning, we strongly recommend oiling your decking to protect the newly exposed timber. Once surface growth has been removed, the bare wood becomes more vulnerable to moisture and further contamination.

• Replacement of damaged boards and corroded decking screws

• 
  

• Hand application of high-quality decking oil such as Liberon

• 
  

• Feeding and nourishing timber to restore natural oils

• 
  

• UV-enhanced, water-resistant protection to prevent weathering

We oil every deck by hand using small brushes, ensuring the wood is “fed” with as much fine-quality oil as it can absorb. This enhances the natural beauty of the timber, restores colour and provides long-lasting protection against water and UV damage.

Where required, we can also re-stain decking to its original tone or adapt and extend existing decking areas, carefully matching the finish as closely as possible.
