A decking job in Easingwold late last month started with a familiar phone call. The boards had gone silver-grey, the shaded end was slippery enough to be a worry, and the owner was halfway to pricing up replacement timber. He didn’t need it. He needed a clean, and if your deck has gone the same way, it helps to know what’s actually involved in decking cleaning. Easingwold has plenty of gardens like this one: a raised softwood deck, ten or eleven years old, the north end shaded by a fence, and the whole thing the colour of an old five pence piece.
The good news is that grey timber is nearly always a surface problem. The colour you remember is still in the wood. It just needs uncovering properly, not blasted at or sanded off.
Grey timber is weathered, not rotten
The silver-grey comes from two things working together. UV light breaks down the surface fibres of the wood and bleaches them, and a thin film of algae settles into the grain on top, which is what makes the boards slippery when it rains. Neither one means the deck is finished.
Before we quote, we check the structure. Press something firm, a key or a screwdriver tip, into the worst-looking board and into the joists underneath where you can reach them. Sound timber resists. Soft, spongy timber that takes a dent is a repair conversation, not a cleaning one. On this Easingwold deck every board passed, which is typical. In our experience most “tired” decks in North Yorkshire are structurally fine and cosmetically miserable.
The decking cleaning Easingwold job, start to finish
The method matters more on decking than on almost any other surface we clean. Softwood boards are exactly that, soft, and a pressure washer used close up chews visible furrows into the grain that never come out.
So the job is a deck soft wash first. A low-pressure application kills the algae and lifts the biological film out of the grain, including down in the grooves where a jet never reaches cleanly. After a gentle rinse, the boards come up clean but still look pale and washed out. That’s expected.
The second stage is the one most people haven’t seen: a timber brightener. It’s a mild acid-based treatment that reverses the grey oxidised layer and lets the original warm tone come back through. Watching it work is the best part of the day. The boards go from driftwood to honey in about twenty minutes, and that’s the “back to gold” in the title, done with chemistry rather than sanding.
This is timber decking restoration without taking anything off the boards. No dust, no hire tools, no millimetres lost.
Why we don’t sand decks back
Sanding gets suggested a lot and it’s nearly always the wrong call. Grooved boards can’t be sanded evenly, the ridges come off before the channels are touched. It generates a garden full of dust, it takes a full weekend, and it removes sound timber you can’t put back. A deck only has so many millimetres to give.
The soft wash and brightener route gets the colour back while leaving the board profile, and the anti-slip grooves, exactly as the manufacturer cut them.
A word on price, since the Easingwold owner asked what most people ask. A typical domestic deck clean and brighten runs from £150 to £300 depending on the size of the deck, access, and how established the growth is. Your quote will depend on all three, which is why we look first and price after.
Keeping the colour once it’s back
Once the timber has dried out for a few days, a decking oil will hold the colour for two to three seasons and slow the greying right down. Skip it and the deck will still be clean and safe, it’ll just drift back to silver sooner. Either way, keeping leaves swept off the shaded end over autumn makes a real difference, because trapped leaf litter is where the algae starts.
