Reviving Grey, Slippery Decking in Spring
Cleaning, sanding and protecting your deck for summer
Timber decking takes a real beating over the winter months. Months of rain, frost and low sunlight leave many decks grey, covered in green algae and dangerously slippery. With the right restoration, though, even a very tired deck can look warm and inviting again in time for summer.
What winter does to decking
Grey decking is caused by sunlight and weather breaking down the surface of the wood. Damp, shady conditions encourage algae, moss and mould, which make the surface slippery and can trap moisture against the timber. Over time, boards can crack, split or lift, and fixings can rust or loosen.
Step by step
Removing dirt and algae
We start by deep cleaning the deck to remove grime, algae and any flaking old finish. Using dedicated cleaners, we lift the dirt and growth out of the grain. The deck then needs time to dry thoroughly before sanding.
Making it safe
Loose boards are re-fixed, protruding screws are replaced and badly damaged boards are swapped for new ones. A sound deck is safer and looks better once finished.
Taking it back to fresh timber
Sanding removes the grey, weathered surface and any remaining coatings, revealing fresh timber underneath. It also smooths raised grain and splinters, making the deck more comfortable underfoot, particularly for bare feet and children.
Protecting
The last step is a protective coat of UV-resistant decking oil. Oils soak into the timber, help repel water and slow down greying from sunlight, without forming a film that can peel. You can choose a clear oil for a natural look or a tinted oil to warm up or even out the colour.
Is your deck worth restoring?
Most timber decks can be restored, even if they look very tired. As long as the boards are not rotten and the frame underneath is sound, cleaning, sanding and oiling will usually bring them back. Try pressing a screwdriver into the timber; if it goes in easily, there may be rot that needs attention. A few damaged boards can be replaced as part of the restoration without the cost of a new deck.
Restoration is a more sustainable choice than ripping up and replacing timber that still has years of life left.
The best time of year
Late spring and early summer are usually the best times for decking restoration. The timber needs to be dry for sanding and oiling, and the oil needs a few dry days to soak in and cure properly. Booking early is a good idea, as many people want their decks ready for the first warm weekends. Autumn restorations are also possible, giving your deck extra protection before winter arrives.
A safer outdoor space
Slippery decking is more than an eyesore; it is a real safety concern, particularly for children and older family members. Regular cleaning and a good protective oil make the surface much safer underfoot.
Key points to remember
Even a grey, mossy and slippery deck can usually be brought back after a hard winter.
Restoration involves deep cleaning, repairs, sanding and a protective UV-resistant decking oil.
Check for rot with a screwdriver; soft timber may need replacing before restoration.
Late spring and early summer are ideal, as the timber and oil need dry weather.
Re-oiling once a year keeps the deck protected and avoids a bigger restoration later.
Keeping decking looking good
Sweep regularly to remove leaves and debris, especially in autumn.
Clean off algae early, before it builds up.
Keep drainage gaps between boards clear.
Apply a maintenance coat of oil annually.
Shift planters and furniture so the timber can dry.
A yearly coat of oil keeps decking healthy and attractive season after season. Leaving it longer usually means a deeper restoration next time.
