Decking Cleaning
Decking can quickly become green and slippery, especially in shaded gardens. We clean timber and composite decking using a method that suits the boards, so they are clean without being stripped or splintered.

Timber decking
Softwood decking is easily damaged by high pressure, which raises the grain and causes splintering. We use a lower pressure and a cleaning solution, working along the boards.
Composite decking
Composite boards are cleaned with a gentle wash suitable for the manufacturer's guidance, to remove algae and dirt without marking the surface.
What we clean
- Softwood timber decking
- Hardwood decking
- Composite decking
- Timber steps and walkways
Our process
- Clear — Furniture and pots are moved off the deck.
- Treat — A cleaning solution is applied to loosen algae and dirt.
- Wash — Boards are cleaned along the grain at a suitable pressure.
- Rinse — The deck is rinsed and left to dry.
What to expect
Cleaning removes green growth and dirt. It does not repair rotten boards or restore the colour of weathered grey timber - re-staining or oiling is a separate job once the deck is dry.
Frequently asked questions
Will cleaning make my decking less slippery?
Yes. Most slipperiness comes from algae, which cleaning removes.
Can you stain or oil my decking?
Our service is cleaning. Decking should be left to dry fully before any stain or oil is applied.
Is composite decking safe to wash?
Yes, with a gentle method that follows the manufacturer's guidance.
