A deck that stays safe, barefoot-ready, and clean every day
Removal of ingrained calima dust and grime
Specialist chemical lifting breaks the bond between micro-fine desert sand and the timber surface. The grain is cleared of embedded dirt, leaving the boards completely smooth under bare feet.
A non-slip walking surface around pools
Clearing the slick film of winter algae and built-up soap residue restores physical traction to wet areas. Swimming pool surrounds become safe for family and visiting guests to walk on safely.
Elimination of silvered grey oxidation
We remove dead surface fibres and sun bleaching without cutting away healthy structural timber. The natural rich amber or dark golden hues of your hardwood return with a balanced, uniform appearance.
Direct sun breaks down natural timber oils, leaving boards pale and thirsty. Fine calima dust enters open pores with morning moisture. This abrasive paste cuts into soft grain under foot traffic.
Heavy rain and poor drainage in shaded corners turn wet boards into an ice rink of black mould. Slipping poolside becomes an immediate danger, while hidden fungal decay softens timber joists beneath the surface.
Leaving untreated decking exposed across the Costa del Sol leads to cupped boards, deep splits, and raised splinters. Once rot reaches the substructure, complete timber replacement is the only remaining fix, costing thousands more than scheduled maintenance.
The right order ensures lasting timber protection
Surrounding areas are masked off — We mask planters, render walls, and polished stone terraces with protective sheeting. Delicate Mediterranean garden foliage receives a thorough fresh-water soak to shield plants against runoff.
Specialist wood cleaner is applied — We apply a tailored exterior wood detergent across the dry deck. The solution sits for ten to fifteen minutes to emulsify oxidised surface oils, ingrained dirt, and red calima dust.
Surfaces are scrubbed along the grain — Stiff-bristled deck brooms work the chemical deep into grooves and timber pores. Manual agitation dislodges stubborn black algae without gouging soft earlywood fibres. We work systematically across each plank.
Residue is washed away gently — Controlled low-pressure washing rinses away detached grime, dead wood cells, and chemical remnants. We keep pressure below eighty bar to prevent the surface splintering caused by aggressive domestic power washers.
Wood brightener restores natural colour — We apply an organic acid neutraliser to balance the timber surface pH after cleaning. The brightener removes dark grey tannin stains and immediately exposes the authentic warm wood tone.
Timber dries to moisture threshold — The wood cures naturally until an electronic moisture meter registers internal levels below twelve percent. Coating damp decking traps moisture inside and causes rot.
Protective penetrating oil is applied — We brush breathable, pigment-rich exterior oil into the open timber pores. The deep saturating treatment repels standing pool water and blocks ultraviolet rays from baking the wood.

Is this what you are looking at?
Black ring marks under planters
Trapped irrigation water leaches natural tannins into wet timber grain beneath heavy pots. Gentle cleaning lifts these dark circles cleanly, provided the timber fibres have not completely rotted underneath.
Peeling clear varnish on steps
Intense heat bakes hard topcoats until they blister and separate from moving wood. Stripping these stubborn flakes leaves bare, open timber ready for breathable care, though uneven shading may linger briefly.
Greasy cooking splatters around grills
Hot cooking oils soak straight into unsealed softwood fibres during outdoor meals. Targeted degreasing dissolves the slippery residue, though very old cooking fat marks may leave faint shadows behind.
Chlorine haze across poolside decking
Splashed pool water evaporates under the afternoon sun, depositing concentrated sanitising salts into the timber face. Thorough rinsing dissolves the pale crust and restores even colour if caught early in the season.
Raised screw heads catching shoes
Repeated drying cycles shrink and twist unsecured boards away from their supporting joists underneath. Deep washing resets the grain before boards curl beyond rescue, but severely warped planks will eventually require physical refastening.
Sun and moisture control how often boards clean
A chemical wash clears out built-up grime, mildew, and gray weathered wood fibers. How long the surface remains clean depends directly on light, moisture, and surrounding plants. Boards open to Mediterranean sun and steady coastal breezes dry rapidly after rain, which stops damp spores from rooting deeply into the timber grain.
Constant shade under a dense tree canopy creates a completely different environment. Falling leaves gather in the joints between planks, trapping moisture against the wood. Standing water and trapped garden litter quickly invite dark algae and slippery mildew back onto the surface, creating serious slip hazards and premature fiber degradation.
Our recommendation is an annual wash cycle whenever planks remain shaded under heavy trees or struggle with trapped water. Boards exposed to open sunlight and clear drainage stay clean for up to 3 years before another full chemical wash becomes necessary.
Complex railings and multiple levels raise job time
A flat residential deck with open borders follows a predictable washing routine. Applying oxygen-based cleaners and rinsing the boards with wide-fan spray tips takes between 2 to 6 hours on an average layout. Water flows off the flat planks easily, allowing uninterrupted progress across the entire floor area without complex detailing.
Extra vertical surfaces change the scope entirely. Handrails, close-set balusters, stairs, and decorative lattice multiply the total square meters of exposed timber. Each individual upright must be washed and rinsed from multiple angles without letting chemicals dry unevenly or leave run marks on lower surfaces. Neglecting these detailed vertical surfaces leaves patchy discolored sections that ruin the look of the finished deck.
A simple 2 to 6 hour schedule suits flat, open floor surfaces without uprights. Planning for extended labor detailing hours is necessary whenever a deck features multi-level steps, dense railings, or surrounding perimeter lattice.
Your questions, answered
Can old weathered boards still be saved by cleaning? +
Surface graying can be washed away, but internal decay cannot. In coastal villas across Marbella, intense sun breaks down surface fibers while joists stay intact. If a screwdriver sinks into soft timber, the board has structural rot and must be replaced rather than cleaned.
What must be checked before washing the timber deck? +
Fasteners, joists, and surface boards must be mechanically sound to bear weight safely. On the Costa del Sol, strong midday heat dries chemicals too fast, so surface temperatures must stay moderate. Washing weak or loose boards causes splintering and risks breaking the subframe.
What happens when too much water pressure is used? +
Narrow, high-pressure jets rip the wood fibers, creating a fuzzy, splintered texture across the planks. It begins as light furring along the grain and leads to deep grooving. Once torn, timber holds moisture longer and catches dirt much faster.
Is a specific trade license required for deck cleaning? +
Washing wooden decks does not require a formal building trade license, and homeowners can legally clean their own timber. However, strict environmental rules govern chemical runoff into storm drains. Strong industrial strippers and specialized biocides also require compliance with regional handling guidelines.
Can solid paint be blasted off with high pressure? +
No, high water pressure tears through soft wood grain long before stubborn paint lifts. That approach ruins the timber profile and causes severe gouging. Where heavy solid coatings fail, we use mechanical sanding or dedicated chemical strippers instead.
Can new protective oil go directly onto cleaned boards? +
We only apply new treatments after the timber dries for 24 to 72 hours. We confirm moisture levels with a calibrated moisture meter first. Sealing wet boards traps water inside, causing stains to blister and wood to rot.
What happens if I am not happy with the wood & deck cleaning? +
