Decking cleaning and restoration in Larkfield. Timber decking goes green and dangerously slippery in winter. We clean the boards and the gaps between them, then treat or oil the timber to bring the colour back. Free quotes.
Wet decking with algae on it is one of the most slippery surfaces in a garden, worse than a patio because the boards are often raised with a step. Cleaning the film off restores the grip. It is the main reason people call us about decking, ahead of how it looks.
More Information
The gaps between deck boards fill with leaf mulch, grit and moss. That packed layer holds water against the timber and is what rots a deck from below. We work the gaps as well as the board faces so the deck can drain and dry properly again.
Bare timber takes oil or stain far better once the grey surface layer is gone. The wood needs a couple of dry days first, so treatment is usually a second visit. Oiled decking sheds water instead of soaking it up, which is what buys you extra years.
Decking needs a lighter touch than paving. Too much pressure furs up the timber and raises the grain, leaving a rough deck that traps dirt faster than before. Seventeen years of cleaning decks around Larkfield has taught us where that line sits on softwood, hardwood and composite boards.

STILL NOT SURE?
Yes, at the right pressure and with the lance kept moving along the grain. Softwood decking is easily furred up by a hard jet held in one spot. We work at lower pressure with a wider fan, which takes the algae off and leaves the board face smooth.
Once a year for most decks, ideally in spring before heavy use or in autumn before the wet months. Decking in shade or under trees greens up faster and may want doing twice. Re-oiling every two to three years keeps the timber protected.
Yes. Composite still collects algae in the grooves even though it does not rot. It cleans at low pressure and does not need oiling afterwards. Composite boards can mark if a lance is held too close, so we keep the pressure down and the distance up.
