How to Bring Your Decking Back After Winter
Getting your outdoor space ready
Winter weather is tough on outdoor timber. 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.
Why decks go grey and green
Untreated or poorly protected timber turns grey as UV light breaks down the surface fibres. In damp or shaded spots, algae and moss grow quickly, creating a slippery and potentially hazardous surface. Left untreated, boards may split, warp or loosen.
How we restore decking
Cleaning
We start by deep cleaning the deck to remove grime, algae and any flaking old finish. A specialist decking cleaner is applied, worked into the grain and rinsed off, often revealing more colour than you would expect. Before the next step, the timber must be fully dry.
Fixing loose and damaged boards
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 gets rid of splinters and rough patches, which matters if children or pets use the deck.
The finishing coat
Finally, the deck is treated with a quality UV-resistant decking oil. Decking oil penetrates the wood, repels moisture and slows down UV greying, without peeling like some paints and stains. You can choose a clear oil for a natural look or a tinted oil to warm up or even out the colour.
When restoration makes sense
Most timber decks can be restored, even if they look very tired. If the boards and frame beneath are structurally sound, restoration is normally possible. A simple test is to press a screwdriver into the boards and joists: if it sinks in easily, the timber may be rotten and need replacing. A few damaged boards can be replaced as part of the restoration without the cost of a new deck.
Restoring rather than replacing is also better for the environment, as it keeps good timber in use for longer.
When to restore decking
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. It is worth booking ahead, as demand rises quickly once the weather improves. Autumn restorations are also possible, giving your deck extra protection before winter arrives.
Reducing slips
Slippery decking is more than an eyesore; it is a real safety concern, particularly for children and older family members. Keeping it clean and properly oiled greatly reduces the risk of slipping.
In summary
Winter rain, frost and shade leave decks grey, green and slippery, but most can be restored.
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.
Plan the work for a dry spell in late spring or early summer for the best results.
Re-oiling once a year keeps the deck protected and avoids a bigger restoration later.
Between restorations
Keep the deck clear of leaves and debris.
Clean off algae early, before it builds up.
Keep drainage gaps between boards clear.
Re-oil once a year, ideally in spring or early summer.
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.
