Decking Cleaning & Pressure Washing in Chichester

Timber & composite decking

A deck is meant to be the best seat in the garden — but left to the coastal damp it turns green, grey and slippery long before its time. We bring it back. Our decking cleaning lifts the algae, black spot and ingrained grime off the boards and out of the grooves, so the timber looks cared for again and is safe to walk barefoot. We clean every kind we see across Chichester and the Witterings:

• Timber & softwood decking — weathered, greying boards cleaned at a gentle, controlled pressure that lifts the grime without furring or gouging the wood.
• Composite decking — the modern boards on so many newer coastal homes, cleaned thoroughly and evenly so the colour comes back without surface damage.
• Steps, rails & edges — the shaded, slow-to-dry corners that go slipperiest first, cleaned along with the main run.

We clean the boards — we do not oil, stain or seal them. It is the same surface-appropriate thinking that runs through the wider pressure washing service and our gentler soft washing work: the right method for the material, never one harsh tool for everything.

Removing algae & black spot

The green slime and stubborn black spots that creep across decking are not just unsightly — they are what makes the boards dangerous. Decking sits low, shaded and slow to dry, and the damp salt air off the coast keeps it wet for weeks, so algae and mould take hold fast:

• Green algae film — the slippery layer washed back to clean, bare board.
• Black spot & mould — the ingrained dark staining lifted out of the timber grain and grooves.
• Salt & sand grime — the fine film the sea air leaves on every deck near Selsey and Bracklesham, rinsed away to bring the colour back.

Slip-hazard removal

A clean deck is a safer deck. Almost everything that makes decking treacherous — the green film, the black mould, the wet slime in the grooves — is exactly what our clean strips away, which matters most on the shaded, sea-facing decks through the wet West Sussex winters. It is work we do right across the harbour villages, from town gardens in Chichester to coastal decks out at West Wittering and East Wittering. If the patio alongside needs the same care, see our dedicated patio cleaning, or for the drive, our driveway cleaning.

Areas we cover

We clean timber and composite decking right across Chichester and the harbour villages: Chichester (PO18, PO19), West Wittering, East Wittering, Bracklesham, Birdham, Itchenor and Selsey (PO20), out to Bognor Regis (PO21, PO22) and Emsworth (PO10) on the Hampshire border. A clean deck is also a safer one — clearing the algae and black spot takes the slip hazard away through the damp coastal winters.
