A clean villa exterior that lasts through changing seasons
Surfaces cleared of embedded atmospheric dirt
Wall coatings look uniform and bright again once baked-in dust layers are cleared away. Mineral films lift off completely without leaving patchy discolouration across the facade.
Algae and black mould eradicated completely
Targeted wash treatments destroy fungal spores inside the render pores instead of just stripping the surface layer. North-facing walls remain free of organic staining throughout damp winter stretches.
Render integrity and paint coatings preserved
Gentle wash techniques clean without chipping plaster edges or abrading paint coats. Preserving the protective finish delays expensive full repainting projects by several years.
Saharan dust settles on porous paint during dry months along the Costa del Sol. Left alone, rain turns mineral dust into gritty paste. The hot sun bakes this residue deep into textured surfaces, turning white walls yellow-brown. Shaded north-facing elevations in Mijas Golf trap coastal damp. Green algae colonies take root in micro-crevices and spread black mould. This organic growth breaks down paint binders and forces water beneath plaster. Pressure washing strips fragile paint, scars base render, and leaves unsightly wand lines across facades.
The sequence that protects delicate facade coatings
Wall surfaces are inspected closely — We examine plaster integrity, expansion joints, and hairline fissures to detect failed paint or active leaks. Catching weak plaster spots early stops liquid seeping behind the decorative finish.
Surrounding landscaping is shielded — We cover mature bougainvillea, citrus trees, paving, and light fixtures with protective sheeting. Pre-wetting adjacent garden beds keeps root systems safe from runoff.
Softwash biocide is gently applied — We spray a low-pressure wash solution formulated for mineral substrates across the walls. The formula loosens bonded dust and neutralises organic growth safely.
Solution is allowed to dwell — The active treatment remains on the wall to reach fungal spores nested inside the texture. Killing fungal roots stops fast winter regrowth.
Render is thoroughly rinsed clean — We use low-pressure water to remove lifted dirt, organic residue, and biocide without scouring the plaster. The controlled spray preserves the coating profile and avoids wand marks.
Mineral streaks receive spot treatment — We treat runoff stains beneath copings and sills with targeted mineral-dissolving products. Removing calcium marks restores a uniform appearance across the facade.
Hairline surface cracks are sealed — We fill minor render fissures identified during washing with breathable, flexible exterior acrylic filler. Sealing small fractures keeps damp coastal air out.
We cover the Costa del Sol
Exterior facade maintenance and gentle render cleaning are delivered across residential estates along the coast. Properties from coastal foothills to beachfront locations receive regular seasonal care.
Is this what you are looking at?
Dark vertical drip marks below window sills
Rainwater collects airborne soot from sill edges and carries it straight down the wall face. Targeted detergent lifts these grey tracks completely if the pigment underneath remains intact.
Brown irrigation spray rings along garden walls
Mineral-rich garden sprinkler water bakes against warm exterior plaster throughout the dry summer weeks. Mild chemical wash treatments dissolve the crusty ring before mineral deposits bind permanently with your paint.
Orange rust stains under metal light fittings
Moist coastal air rusts tiny internal screws inside decorative fixtures and bleeds orange fluid down the plaster. Acid-based spot cleaners lift the streak cleanly, though unsealed fittings will eventually weep again.
Grey soot smudges over outdoor kitchen grills
Charcoal smoke and warm airborne cooking fats settle directly into coarse wall texture during summer dining. Gentle degreasing cleans the darkened patch back to an even tone without scouring the base render.
Spiderweb cracks trapping dark moisture lines
Microscopic shrinkage cracks draw in damp winter mist and trap tiny airborne mould spores inside the gaps. Washing removes the shadowed lines now, though widening fissures eventually require flexible caulking to stop water ingress.

Washing during hot midday sun or cooler hours
Exterior render heats up rapidly under strong coastal sunlight. When chemical cleaning solutions land on a hot wall, the liquid flashes off before it can break down ingrained organic growth. Softwash treatments require an active dwell time of at least 15 minutes to eliminate living spores properly. Intense surface heat causes chemical detergents to evaporate within seconds instead of working into the render texture.
Rapid drying forces active salts out onto the wall surface, leaving unsightly mineral blooming and permanent bleached spots across decorative paint films. Early morning or overcast hours keep wall temperatures safely within the working range of 5°C to 30°C. Sticking to cooler hours prevents chemical burn, eliminates costly remedial re-coating, and allows the washing solutions to lift stains safely without drying out.
Direct ground access or hired aerial lift equipment
A typical residential property takes 0.5 to 1.5 days to wash thoroughly from exterior perimeter boundaries. Low-level walls allow operators to apply detergents and rinse facades safely using ground-based telescopic lances. However, trying to reach upper storeys from the lawn changes the spray angle completely. Spraying upward from a steep distance pushes water behind window seals and strips surface aggregate unevenly.
We handle single-storey elevations efficiently using ground-level application equipment without machinery surcharges. Whenever building heights exceed safe ground reach, budgeting for a mobile elevated work platform or fixed scaffolding becomes necessary. Aerial access machinery adds hire fees and requires certified operators, but it keeps nozzle angles straight. Proper working height prevents permanent gouging to brittle monocouche renders and protects surrounding roof tiles from heavy foot traffic.
On-site checks that determine your final facade quote
Our preliminary survey examines your walls for structural faults and underlying moisture before any washing starts. If the assessment reveals active penetrating rainwater leaks or untreated rising damp, wet cleaning is postponed entirely. Washing a saturated wall forces trapped water deep into the structure and risks major delamination. Correcting underlying structural faults through facade and render repair must happen first, meaning cleaning is quoted as a secondary phase once masonry dries out fully.
The inspection also tests whether wall discolouration consists of standard green algae or dense atmospheric carbon soot and grease. Light organic biofilms require low-pressure chemical biocides, keeping equipment needs minimal and turnaround times within one standard working day. Heavy exhaust carbon, tree sap, or old paint residues demand low-pressure superheated steam reaching 150°C at the nozzle. This thermal treatment cleans thoroughly without soaking porous plaster, but it adds specialized machinery setup and extra labour hours to your final quote.
Your questions, answered
How long will a clean render surface stay clear? +
A biocidal wash keeps growth away for 2 to 5 years. Leaking gutters, dense garden shade, or persistent damp shorten this span quickly. A breathable repaint lasts 10 to 15 years before a new coat is needed.
Can damaged or hollow render still be washed? +
No, detached render must be repaired before washing. Hollow sections cannot hold moisture, and cleaning forces water behind loose shells. We also refuse pressure washing on thin-coat finishes because high pressure strips the protective aggregate.
Can scarred render from past power washing be fixed? +
Wand gouges and stripped aggregate cannot be washed away. High pressure tears the outer render shell permanently. Minor surface damage can be smoothed with breathable mineral coatings, but blown or hollow sections require fresh plastering before any future wash.
Is regular washing cheaper than repainting the walls? +
Washing costs far less than premature painting when render has merely discoloured. On villas across Marbella, clearing biological build-up every few years preserves the original plaster. Skipping maintenance forces early repainting, which costs substantially more across large exterior wall surfaces.
How many days does facade cleaning usually take? +
Masking glass and plants takes 1 to 3 hours before work starts. Cleaning a standard detached home takes 0.5 to 1.5 days. The walls must then dry fully for 24 to 48 hours before applying sealants or paint.
How is the right cleaning method chosen for facades? +
Our choice depends on the wall finish and dirt level. Modern synthetic renders on the Costa del Sol suit low-pressure biocidal washing, whereas mineral plasters benefit from superheated steam up to 150°C. Steam lifts tough grease without soaking old wall fabric.
