Restore your decking without the risk of damage with our professional Decking Cleaning Liverpool service. We use a gentle soft wash method to remove green algae, black mould and dirt from your timber. No high pressure, no splintered wood — just a deep clean that brings your deck back to life.
If you’re looking for Decking Cleaning Liverpool that won’t ruin your timber, you’ve come to the right place. Decking takes a real battering from the rain and damp. Green algae builds up, mould gets in the grain and before you know it, your deck’s slippery and looking tired. We use soft washing techniques to clean it safely without damaging the wood.
When people search for Decking Cleaners Near Me, they want someone who knows timber isn’t the same as concrete. We get that. Low pressure, the right cleaning solutions and a finish that leaves your deck ready for staining or just enjoying as it is.
Green slippery algae that turns your deck into an ice rink when it rains, black mould growing in the grain, dirt ground in from foot traffic, and timber that’s gone grey and lifeless. Sound familiar? Liverpool’s wet weather means algae and mould spread fast on decking. Leave it too long and it gets ingrained.
That’s why regular Liverpool Decking Cleaning is the way to go. We remove the algae, lift the mould and bring the natural colour back to your timber. No damage, no pressure blasting — just a proper clean done right.
That green film isn’t just ugly — it’s lethal when wet. Our Decking Cleaning Liverpool removes the algae completely, giving you a safe surface for the kids, the dog and summer barbecues.
Grey, tired-looking decking can make your whole garden feel drab. We strip away the dirt and oxidation, revealing the warm natural colour of the timber underneath. It’ll look like new.
If you’re planning to oil or stain your deck, it needs to be properly clean first. We remove all the old grime and mould so your new treatment can soak in properly and last longer.
Mould and mildew don’t just sit on the surface — they get into the wood grain. Our cleaning kills the mould and washes it away, stopping it from spreading further.
We don’t use high pressure on decking. Blasting timber with a pressure washer can splinter the wood, roughen the grain and force water into the joints. Instead, we use a soft wash system — low pressure combined with specialist cleaning solutions that lift the algae and mould without damaging the wood.
This method is gentler on your decking but just as effective. The results speak for themselves. Clean timber, safe surface, no damage done.
We check the type of timber, the condition of the boards and how much algae and mould has built up. We also look for any loose boards or damaged areas that need attention.
We spray a biodegradable cleaning solution across your decking. This breaks down the algae, mould and dirt without you needing harsh chemicals or high pressure.
Using low-pressure water, we rinse the solution and the loosened dirt away. The algae and mould come off with it, leaving the wood grain clean and intact.
We clear away any debris and leave your decking looking fresh. If you want it staining or oiling after, we can sort that too. Otherwise, it’s ready to enjoy.
Once a year keeps most decks looking good. If your decking is in a shaded spot or under trees, you might need it doing every six months. Algae grows fast in damp conditions, so don’t let it build up.

Sweep your decking regularly to stop dirt and leaves building up. Move your pots and furniture around now and then so the whole deck gets sunlight. If you see algae starting to appear, get it cleaned off before it spreads. And if you’re staining, make sure the timber is bone dry first.
Our decking cleaning services start from £100. The price covers a standard-sized garden deck (approximately 20-30 square metres) and includes a full soft-wash treatment to remove green algae, black mould, and general dirt. We use a specialist decking cleaner that is applied at low pressure to avoid damaging the wood fibres. Unlike a high-pressure jet wash, which can splinter and ruin timber decking, our method is gentle and thorough. The price includes a full rinse and a prepared surface ready for staining or oiling. For larger decks, composite decking, or decking that has not been cleaned for many years, the cost will be higher. We provide a clear, upfront quote with no hidden extras.
We aim to provide a same-day quote for decking cleaning across Liverpool, Wirral, and Sefton. A simple photo of your deck showing the level of green algae or mould is usually enough for us to give you a firm price. We know that you want to get your garden ready for summer barbecues or family gatherings. We can often schedule the work within a few days of your quote. We keep our diary flexible to accommodate urgent requests. As a local family-run business, we are responsive and committed to getting your garden looking its best quickly.
Pressure washing is often too aggressive for wooden decking and can cause significant damage. The high-pressure water can strip the soft grain of the wood, leaving a rough, splintered surface that is uncomfortable to walk on. It can also force water deep into the wood, causing it to rot from the inside out. The pressure can dislodge nails and screws, leaving your decking loose and dangerous. Our soft-wash method uses a specialist decking cleaner applied at low pressure. This cleaner lifts the algae and mould without damaging the timber. The result is a clean, smooth deck that is ready for oiling and safe for bare feet and children.
Yes, we clean composite decking, but we use a different approach. Composite decking is made from a mix of wood fibres and plastic. It is more durable than timber, but it can still get a film of green algae and dirt that makes it look dull. Because composite decking can be scratched by abrasive cleaning, we use a specialist composite cleaner and a soft brush attachment. This lifts the dirt and algae without scratching the surface. We then rinse thoroughly to leave a clean, streak-free finish. Composite decking does not require the same level of care as timber, but it still benefits from a professional clean once a year to keep it looking its best.
Your decking will typically be dry enough to walk on within a few hours after cleaning, but we recommend waiting 24 to 48 hours before applying a stain or oil. The wood needs time to dry out fully after the soft-wash treatment. If you apply oil to damp wood, it will not penetrate properly and will peel off quickly. We always advise our customers to allow the decking to dry for a full day in good weather. If the weather is cooler or damp, we recommend waiting two days. Once the decking is fully dry, it is ready for oiling, which will protect it and keep it looking great for the rest of the season.
