Frequently Asked Questions

Will high-pressure power washing gouge or splinter my wooden decking?

Yes, using standard high-pressure power washers too close to timber can easily strip wood fibres, cause splintering, gouge deep lines, and ruin the smooth finish of your deck. We use specialized, low-pressure rotary wood washers and gentle softwash cleaning solutions to lift surface grime and organic growth cleanly without destroying the timber surface.

Yes. Composite decking features synthetic capped coatings and delicate wood-plastic grains that require low-pressure care. We use non-abrasive, pH-neutral cleaning agents combined with soft-bristled brushes and low-pressure rinses to dissolve grease, food spills, and green algae without scratching, dulling, or stripping the composite surface finish.

Decking turns dangerously slick due to the buildup of micro-algae, fungi, and wet leaf mould that thrive in Central Scotland’s damp, shaded climate. This organic film traps moisture along the timber grooves, creating a invisible, slippery layer underfoot that poses a serious fall hazard for family and guests.

Yes! Once your wooden deck has been thoroughly deep-cleaned and allowed to dry completely, we offer professional decking oil and wood stain application. Applying high-quality penetrating oils restores lost natural moisture, protects against UV greying, seals out rainwater, and brings out the rich, natural grain of the timber.

Standard surface washing clears surface dirt and organic growth, but peeling paint or flaking thick stains may require targeted wood-stripping treatments. We assess the condition of your timber coating during your initial quote and apply appropriate softwash strippers or wood restorers to lift failing finishes back to bare wood.

Timber must dry out thoroughly before any oil, stain, or protective seal can be applied—typically requiring 24 to 48 hours of clear, dry weather following a deep wash. Applying oil to damp wood traps moisture inside, leading to wood rot, premature flaking, and cloudy grey patches.

Yes, property and plant safety is guaranteed. We exclusively use fully compliant, biodegradable softwash solutions. Prior to applying any chemical treatment, we thoroughly saturate adjacent lawn borders, flowerbeds, and shrubs with fresh water to shield them, rinsing everything clean again once the process is complete.

Our rotary surface cleaners and soft-bristled brush attachments force cleaning solutions and water streams down into the narrow grooves and joint gaps between boards. This lifts trapped leaf sludge, dirt, and moss that hold moisture and cause structural timber rot beneath the surface.

For residential properties in Central Scotland, an annual professional clean in early spring is ideal to strip away winter moss, algae, and leaf decay. Annual maintenance prevents slippery hazards and keeps timber conditioned to withstand harsh seasonal weather.

Our pricing is completely transparent and based on the total surface area (square meters) of your deck, the decking material (hardwood, softwood, or composite), its current condition (level of algae, peeling stain), and whether post-clean oiling or sealing is requested. We provide instant, accurate fixed quotes via satellite and photo assessments.

Expert Decking Care & Timber Restoration Across Central Scotland

A garden deck should be a stylish, functional extension of your living space, ideal for outdoor dining and relaxing. However, Central Scotland’s wet weather and falling leaves quickly cause timber and composite decking to accumulate green algae, black mold, and atmospheric pollution. Over time, this transforms beautiful outdoor spaces into hazardous, unsightly, and slippery surfaces.

Our professional decking cleaning service restores your timber and composite decking back to a safe, pristine state. Combining low-pressure softwash treatments with specialized non-strip washing, we eliminate stubborn organic growth without splintering wood fibres or scratching composite panels. We revitalize your entire deck area, extending its structural lifespan and making your garden safe for year-round use. For roof cleaning in Glasgow, choose Outside Clean.

Softwood & Hardwood Timber Deep Wash

Controlled, low-impact cleaning that lifts green algae, moss, and weathered grey wood film while preserving natural timber grain.

Composite Decking Softwash

Gentle, non-abrasive chemical cleaning engineered to lift stubborn food stains, grease, and algae without scratching composite caps.

Timber Re-Oiling & UV Protection

Optional application of deep-penetrating exterior wood oils that nourish timber, resist water ingress, and block UV greying.

Gentle, Damage-Free Cleaning for Lasting Safety

Restoring wooden or composite decking requires delicate, specialist equipment suited to timber care. Using domestic high-pressure lances on wooden boards often results in gouged grooves, raised splinters, and ruined timber surfaces that require expensive replacement. We use controlled rotary wood washers and tailored softwash solutions to deliver a deep, uniform clean that protects your investment.

By eradicating algae spores deep within timber grooves and board gaps, our chemical softwash treatments prevent slippery moss and fungi from rapidly returning. Whether preparing your garden for summer entertaining or restoring a weather-worn deck, our expert care delivers safe, long-lasting, and visually impressive results every time.

Low-Impact Wood Rotary Cleaners

Enclosed surface cleaner technology designed specifically for timber, providing even water distribution without stripping wood fibres.

Biodegradable Softwash Biocides

Deep-sanitizing washes that digest green algae, lichen, and mildew spores buried deep inside timber pores and board joints.

Grain-Enhancing Wood Preservation

Professional application of protective stains and oils that seal timber against water rot, splitting, and winter frost damage.

Why Choose Professional Decking Cleaning

Attempting to clean timber or composite decking with domestic high-pressure washers can easily strip wood fibres, cause severe splintering, and permanently gouge board surfaces. Wooden and composite decks require gentle pressure control and targeted chemical treatments to lift embedded organic growth safely. Investing in professional decking cleaning ensures your outdoor living space is thoroughly sanitized, slip-free, and protected against structural decay. Here is why homeowners across Central Scotland trust our expert team to care for their decking.

Non-Destructive Low-Impact Cleaning

We utilize specialized rotary wood cleaners and low-pressure softwash methods that lift surface grime and algae without splintering timber, gouging grooves, or scratching synthetic composite panels.

Deep-Pore Algae & Spore Sanitization

Our biodegradable softwash biocides digest green algae, moss, and mildew spores buried deep within timber pores and board gaps, preventing rapid regrowth and keeping surfaces clean longer.

Restoration of Slip-Free Safety

Eliminating the slick layer of micro-algae, wet leaf sludge, and fungi removes dangerous fall hazards, making your garden decking safe for family and guests year-round.

Protective Timber Oiling & UV Sealing

We offer deep-penetrating exterior wood oils and stains that nourish dry timber, restore lost natural colour, block UV greying, and form a water-repellent seal against winter rot.

Complete Board Gap & Joist Sludge Removal

Our high-volume wash technique clears out trapped leaves and rotting debris from narrow board gaps, allowing proper drainage and preventing hidden structural joist decay.

I am extremely happy with the roof and driveway cleaning services provided by Jaimie and the team at Outside Cleaning Limited. They thoroughly removed the moss from the roof, cleaned the gutters and even cleaned all the windows, doors, and the garage door as part of the job. Once the cleaning was complete they made sure all the debris was cleared away and left everything spotless. Jaimie also took the time to provide helpful advice on how to maintain the roof and keep it in good condition. The team was professional and thorough. I would highly recommend Outside Cleaning Limited to anyone looking for exterior cleaning services.

Jaimie and the team cleaned our roof and we were really happy with the results. It’s spotless and they left the garden and bits around the house incredibly tidy. What I think sets these guys apart though is how they look after customers. Communication was brilliant throughout the whole process, they sent a really helpful video before the job that told us what to expect and that no surprises approach made a big difference for us. On price, we got a few different quotes and Outside Clean Ltd were really competitive. I’d have no hesitation using them again and have already recommended to friends and family.

Just had our roof cleaned by Outside Cleaning. They arrived early, very friendly and approachable. Jaimie and team were very professional and did a fantastic job. Our roof was completely transformed and everything was cleaned up afterwards including our neighbours paths. Great job and well worth the money. We don't recommend people that often but would certainly recommend Jaimie and team. Basically they completely do what they advertise. Thanks for a cracking job.
