Decking Cleaning Liverpool, a safe soft-wash for your timber

Our decking cleaning starts from £100 for a small deck, from £150 for a medium deck and from £200 for a large one. Every price includes a full soft-wash treatment to remove green algae, black mould and general dirt, a thorough rinse, and a surface left ready for staining or oiling if you want it.

We use a specialist decking cleaner applied at low pressure, so the wood fibres aren’t damaged the way they would be with a high-pressure jet wash. Heavy mould, decking that hasn’t been cleaned for years, or composite boards that need a dedicated cleaner can push the price towards the top of each range, and we’ll always tell you that before we start.

Most decks sit right next to a patio or path, and it’s usually cheaper to have both done on the same visit than to book them separately. Our patio cleaning can be added to the same quote, and the whole garden will look finished rather than half done.

• Small decks from £100
• Medium decks from £150
• Large decks from £200
• Soft-wash method protects the wood

Usually the same day. A couple of photos of your deck showing the size and how much green algae or mould is on it are normally enough for a firm price. A wide shot of the whole deck and a close-up of the boards gives us everything we need.

We know you want the garden ready for barbecues, birthdays and sunny weekends, so we try to book the clean within a few days of your quote. As a local family-run business, we keep the diary flexible, and we’re open seven days a week from 7am to 7pm, which makes it easier to fit in around you.

Send your photos over WhatsApp and you’ll get 10% off your quote. If you’d rather speak to someone, give us a ring or fill in the form on our contact page and we’ll get straight back to you. There’s no obligation, and if we think the boards need repairs rather than a clean, we’ll tell you honestly.

Because it’s often too aggressive and can do real damage. High-pressure water strips away the soft grain of the timber, leaving a rough, furry surface that splinters and feels horrible under bare feet. It can also force water deep into the boards and the joints, which leads to swelling and rot over time.

Too much pressure can even loosen screws and nails, leaving boards that rock or lift. Lots of decks we’re asked to look at were damaged by a DIY jet wash rather than by the weather. Our soft-wash method uses a specialist cleaner applied at low pressure, which lifts the algae and mould without tearing up the timber, leaving a smooth, clean deck that’s safe for children and pets.

It’s a different job altogether from our driveway cleaning, where block paving and concrete can take a 5000 PSI machine. Timber needs a gentler touch, and that’s exactly how we treat it.

• High pressure strips the wood grain
• Causes splinters and rough boards
• Can loosen screws and nails
• Soft-washing is the safe alternative

Yes, but we use a different approach. Composite decking is a mix of wood fibres and plastic. It’s tougher than timber and won’t rot in the same way, but it still picks up a film of green algae, dirt and black spots that dull the colour and make it slippery.

Composite can scratch if it’s cleaned with harsh brushes or the wrong products, so we use a specialist composite cleaner and a soft brush attachment that lifts the dirt and algae without marking the surface. We then rinse it thoroughly for a clean, streak-free finish. It doesn’t need oiling or staining afterwards, and a yearly clean keeps it looking its best.

We clean a lot of newer composite decks on modern homes and extensions across the Wirral, including Heswall. Composite often sits alongside plastic doors and window frames, and our UPVC cleaning can be done on the same visit to bring the whole back of the house up together.

• Specialist cleaner for composite boards
• Soft brush prevents scratching
• No oiling or staining needed
• Yearly clean recommended

It’s usually dry enough to walk on within a few hours, but you should wait 24 to 48 hours before staining or oiling. Timber soaks up water during the clean, and it needs time to dry right through, not just on the surface. Oil or stain applied to damp wood won’t soak in properly and tends to peel off quickly.

In good weather a full day is normally enough. If it’s cool, damp or the deck is in shade, give it two days. Keep heavy furniture and plant pots off the boards until they’re dry, because trapped moisture under a pot can leave a mark. Composite decking dries much faster than timber, and you can usually use it the same day.

While your deck is drying, it’s a good time to get other jobs done. If leaves and moss from the roof keep landing on the deck, our gutter cleaning stops overflowing water dripping onto the boards, which is one of the main reasons decks go green in the first place.

• Walkable within a few hours
• Fully dry in 24 to 48 hours
• Wait before oiling or staining
• Composite dries much faster

It’s almost always a film of green algae, and cleaning it off makes a big difference. Algae grows on timber that stays damp, especially in shade, under trees or where water drips from the roof. When it rains, that green layer turns slimy and the deck becomes dangerous, particularly for children, older relatives and pets.

Our soft-wash treatment kills the algae and lifts it out of the grain rather than just smearing it about. Once it’s gone, the boards have proper grip again. Keeping the deck swept, moving pots around so the whole surface gets light, and trimming overhanging branches all help it stay safer for longer.

Patios suffer from exactly the same problem, especially in the colder months. Our guide on why your patio goes slippery in winter explains what causes it and what you can do, and most of the advice applies to decking too. If your deck feels like an ice rink every time it rains, send us a photo and we’ll take a look.

• Green algae is the usual cause
• Soft-wash kills it in the grain
• Grip comes back once it’s gone
• Sweep regularly and let the light in

Yes, we can sort that for you once the timber is fully dry. A proper clean is the most important part of any staining job, because oil and stain can’t soak into wood that’s covered in algae, mould and dirt. Cleaning first means the new finish bonds properly and lasts much longer.

After the soft-wash we leave the deck to dry right through, which usually takes 24 to 48 hours depending on the weather. Then the oil or stain can go on evenly, with no trapped moisture underneath. We’ll talk to you about the finish you want before we start, whether that’s a clear oil to bring out the natural colour or a tinted stain to freshen up older boards.

If the rest of the garden has got away from you, our garden restoration service can clear the overgrown beds and borders around the deck. That way, when the deck is clean and freshly oiled, the garden around it looks just as good.

• Clean first so the finish lasts
• Timber dried for 24 to 48 hours
• Oil or stain applied evenly
• Garden tidy-ups available too

Once a year keeps most decks looking good. A yearly clean stops algae and mould getting a proper hold, keeps the boards safe to walk on, and makes each clean quicker because there’s less to remove. Spring is a popular time, so the deck is ready for the summer.

If your decking sits in a shaded spot, near a hedge or under trees, you might need it doing every six months. Algae grows fast in damp, sheltered conditions, and leaves sitting on the boards hold moisture against the wood. Gardens with lots of mature trees, like many around Woolton, tend to need a clean more often than open, sunny ones.

The same goes for homes near pine woods, where needles and sap collect between the boards, such as in parts of Formby. Regular sweeping between cleans makes a real difference wherever you live. A quick brush once a week clears leaves and needles before they hold moisture against the timber and start to stain it.

• Once a year for most decks
• Every six months in shade
• More often under trees
• Sweep between cleans

Yes, as long as it isn’t freezing. We can soft-wash decking for most of the year, and winter is often when algae is at its worst and the boards are at their most slippery. We avoid working in hard frosts, because water left on the boards can freeze and make them even more dangerous.

The main thing to know is that drying takes longer in the colder months. If you’re planning to oil or stain the deck after the clean, it’s usually better to wait until spring when the timber can dry out properly. A winter clean still gets rid of the green layer and makes the deck safer to use, and the finish can be added later.

If you’re wondering whether to book now or wait, our guide on whether winter is a good time for exterior cleaning explains the pros and cons for decking, patios and other surfaces. Our diary is often more flexible in winter too, so it can be easier to get a date.

• We avoid hard frosts
• Algae is often worst in winter
• Oiling is best left until spring
• More flexible winter diary

Yes, we take care with everything around the deck. Our cleaner is designed for timber and is used at low pressure, so there’s no harsh spray drifting across the garden. We rinse nearby plants before and after the clean, and we ask you to keep pets inside until we’ve finished and the boards have been rinsed down.

If you’ve got a pond, a vegetable patch or a water feature close to the deck, just let us know before we start. We’ll cover or protect it and control the run-off so it doesn’t end up where it shouldn’t. Once the deck has been rinsed and dried, it’s fine for children and pets to use again.

While we’re in the back garden, it’s worth looking at the walls around the deck too. If the house or garden walls have gone green from the same damp conditions, our brickwork cleaning uses a gentle soft-wash and biocide, and can be done on the same day.

• Low pressure, no harsh spray
• Plants rinsed before and after
• Ponds and beds protected
• Pets back out once rinsed
