Red algae, green mould, and dark atmospheric streaks ruin modern render. We restore K-Rend, silicone, and painted exterior walls safely using low-pressure soft washing — never high-pressure jet washing.

We specialize in low-pressure soft washing designed specifically for delicate exterior renders, through-coloured monocouche, and painted masonry facades.
High-pressure jet washing should never be used on render. Blasting render with high-pressure water strips the protective surface layer, causes permanent gouging, and forces water into structural substrate gaps. Instead, we apply specialized, eco-friendly biocide solutions at low pressure to kill organic growth and microscopic spores at the root.
Every render clean includes a gentle rinse down of surrounding glass, windows, and downpipes, restoring your building facade safely without requiring an expensive repainting job.
Crawley’s damp climate and road pollution cause rapid colonization of biological growth on rendered walls. Left untreated, algae eats into porous render finishes and severely degrades your property’s exterior appearance.
Dirty or stained render rarely needs painting. Professional soft washing removes organic discolouration and restores the original pigment of your render at a fraction of the cost of scaffolding and repainting.
High-pressure washing destroys render surfaces and forces water behind insulation layers. Soft washing relies on safe chemical action to sanitize the wall without causing physical structural damage.
Unlike pressure washing which leaves microscopic algae spores alive inside porous render, our soft wash treatments sterilise the substrate to prevent red and green algae from returning for years.
Crawley’s damp climate, humid winters, and road pollution provide the ideal conditions for red algae (Trentepohlia), green mould, and dark carbon streaks to colonise modern rendered facades. Most rendered properties here look prematurely aged and discoloured long before the render itself is compromised — what you’re seeing is organic biological growth and traffic film bonded to the outer porous surface.
Our approach is safe, chemical-led, and careful: we avoid high-pressure water blasting entirely, as intense pressure strips protective render coats and forces water into structural cavities. Instead, we rely on specialised low-pressure soft wash treatments that neutralise spores at the root, lifting stains and restoring your building’s original appearance without the expense of scaffolding and repainting.
Red algae stains and atmospheric carbon pollution can make a modern rendered property look neglected within just a few years. At Jet It All, we restore K-Rend, silicone render, monocouche, and painted exterior walls back to their original vibrant finish across Crawley and West Sussex. We use specialized, low-pressure soft washing equipment that cleans thoroughly without compromising delicate render coatings or forcing water into internal wall cavities.
Render surfaces are fragile and prone to chipping under high pressure. We use low-pressure delivery pumps—applying gentle pressure—to saturate the wall surface safely without blowing holes or eroding surface textures.
Crawley’s damp atmospheric conditions cause heavy vertical red and green algae streaking. Our biocide solutions target these organic growths, dissolving them completely and bringing back clean wall surfaces.
Different render types require tailored chemical treatment formulations. Whether your property features through-coloured K-Rend, flexible silicone, or traditional pebble dash, we match our biocide mix precisely to your surface material.
Property owners often believe dirty render needs a full repaint. Professional soft washing lifts organic staining and reveals the original bright colour beneath, preserving render breathability and saving you thousands of pounds.
Properties located near busy roads, M23 access points, or Gatwick flight paths absorb carbon pollution and traffic film. We wash away environmental grime to leave a clean, uniform wall finish.
Our soft wash treatments penetrate deep into the pores of the render to kill invisible spores. The residual biocide active ingredient stays inside the substrate pores, inhibiting regrowth for up to 5 years.
High pressure washing causes permanent, irreversible damage to rendered walls. Intense water streams strip the protective top skin, etch unsightly lines into the surface finish, and force water into structural cavities causing internal damp. Soft washing relies on safe chemical action rather than mechanical force to clean render safely.
Because soft washing sterilises organic growth at a microscopic level, results last significantly longer than high-pressure blasting. Depending on shade, tree cover, and elevation exposure, a soft-washed rendered wall in West Sussex typically remains free of red and green algae for 3 to 5 years.
In the vast majority of cases, no! Most render staining is caused by surface-dwelling algae and lichen rather than faded pigment. Once we remove the organic staining via soft washing, the original colour of your K-Rend or monocouche render is revealed beneath.
We take thorough protective measures to safeguard your garden. Before applying any soft wash solutions, we wet down all nearby grass, shrubs, and flower beds with fresh water. We cover sensitive foliage and thoroughly rinse surrounding areas after treatment to keep your garden safe.
Render cleaning costs depend on the total surface area, building height, access requirements (such as cherry pickers or towers), and the severity of the algae buildup. A typical domestic render clean in Crawley ranges from £300 to £800. We always provide a fixed, written quote upfront.
