Restore your decking without the risk of damage with our 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.
Decking takes a real battering from the rain and damp. Green algae builds up, mould gets into 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.
Timber isn’t the same as concrete, so it needs a different approach. Low pressure, the right cleaning solution, 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, and leaving it too long means it gets ingrained.
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 dangerous when wet. We remove 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.
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 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 a specialist cleaning solution that lifts the algae and mould without damaging the wood.
This method’s gentler on your decking but just as effective. Clean timber, safe surface, no damage done. If your patio needs the same treatment, we can sort both on the same visit.
We price by the size of the job in front of us, not a fixed rate per square metre. Here’s a rough guide, but the exact figure always depends on the size of your deck and how much algae or mould we’re dealing with.
| Deck size | What’s included | Typical price |
|---|---|---|
| Small | Soft-wash treatment, algae and mould removal | from £100 |
| Medium | Soft-wash treatment, algae and mould removal | from £150 |
| Large | Soft-wash treatment, algae and mould removal | from £200 |
These are starting prices for a standard clean. Heavy mould, decking that hasn’t been cleaned in years, or composite decking needing a specialist cleaner can push the price toward the top of each range, we’ll always be upfront about that before we start. The easiest way to get an exact figure is to send us a couple of photos on WhatsApp, we’ll usually get a firm price back to you within about 10 minutes.
We check the type of timber, the condition of the boards and how much algae and mould has built up, and look for any loose boards or damaged areas that need attention.
We spray on a specialist decking cleaner. This breaks down the algae, mould and dirt without 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’s 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.
We’re a family-run Liverpool business, trading since 2018, with over 200 properties restored and a 5.0 rating. We know timber needs a different approach to paving, and we’ve got the right kit and know-how to do it properly. No call centres, no hard sell, just honest, reliable work.
Fully insured, we turn up when we say we will and we don’t leave till you’re happy. Whether it’s a one-off clean or regular maintenance, we’ll look after it properly.
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’s bone dry first. If the garden around your decking’s gotten away from you, our garden restoration service clears it in the same visit.
Our decking cleaning starts from £100. That covers a small garden deck, and includes a full soft-wash treatment to remove green algae, black mould and general dirt. We use a specialist decking cleaner applied at low pressure to avoid damaging the wood fibres, unlike a high-pressure jet wash, which can splinter and ruin timber decking. The price includes a full rinse and a prepared surface ready for staining or oiling. Larger decks, composite decking, or decking that’s not been cleaned for years cost more.
Usually a same-day quote. A simple photo of your deck showing the level of green algae or mould is usually enough for a firm price. We know you want the garden ready for summer barbecues or family gatherings, and we can often schedule the work within a few days. As a local family-run business, we keep the diary flexible for urgent requests.
It’s often too aggressive and can cause real damage. High-pressure water can strip the soft grain of the wood, leaving a rough, splintered surface that’s uncomfortable to walk on, and it can force water deep into the wood, causing it to rot from the inside out. It can even dislodge nails and screws, leaving your decking loose and dangerous. Our soft-wash method uses a specialist cleaner applied at low pressure that lifts the algae and mould without damaging the timber, leaving a clean, smooth deck safe for bare feet and children.
Yes, though we use a different approach. Composite decking’s a mix of wood fibres and plastic, more durable than timber, but it still gets a film of green algae and dirt that dulls it down. Because composite can be scratched by abrasive cleaning, we use a specialist composite cleaner and a soft brush attachment that lifts dirt and algae without scratching the surface, then rinse thoroughly for a clean, streak-free finish. It doesn’t need the same care as timber, but still benefits from a professional clean once a year.
Usually dry enough to walk on within a few hours, but wait 24 to 48 hours before staining or oiling. The wood needs time to dry out fully after the soft-wash treatment. Oil applied to damp wood won’t penetrate properly and will peel off quickly. We’d advise a full day in good weather, or two days if it’s cooler or damp. Once fully dry, it’s ready for oiling, which protects it and keeps it looking great for the rest of the season.
