Restore the pristine appearance of your property’s exterior walls without risking structural damage. Serving Porthmadog and a 40-mile surrounding radius, we specialise in professional render cleaning that safely eliminates ugly red, green, and black algae staining. Using advanced low-pressure soft washing technology, we treat K-Rend, monocouche, and traditional sand-and-cement renders, bringing your home or commercial building back to its original showroom finish safely and effectively.
Modern building renders look stunning when first applied, but the damp, humid, and coastal climate across North Wales creates the perfect breeding ground for organic growths. Within just a few years, beautiful exterior walls can become disfigured by unsightly streaks of bright green algae, black mold, and aggressive red staining. Our professional render cleaning service offers the ultimate solution. Instead of using aggressive high pressure, which can easily crack and scar delicate wall surfaces, we apply a specialised soft wash treatment. This process gently dissolves heavy environmental staining and kills the underlying organic spores at a molecular level, entirely reviving your property’s kerb appeal while protecting the underlying fabric of the building.
Stained exterior walls don’t just lower your property’s market value; they also signal a deeper biological problem that can damage your building materials. Render requires highly specialised maintenance, and treating it incorrectly can lead to catastrophic, expensive mistakes. Here is how our professional render cleaning service eliminates your worries and safely restores your walls.
Many homeowners and inexperienced contractors mistakenly try to clear wall stains using a standard high-pressure jet wash. This brutal force easily punches holes into the surface, tears the render away from the brickwork, and causes permanent structural scabs. We solve this by using zero-force soft washing, depending entirely on safe chemical reactions to lift the stains flawlessly.
Aggressive atmospheric spores like Trentepohlia create vibrant red streaks down property gables, while black mold establishes itself beneath gutters, making even luxury buildings look derelict. Ordinary soapy water cannot shift these deeply embedded organisms. Our target treatments neutralise these specific biocide strains instantly, bleaching out the ugly discolouration perfectly.
Scrubbing your walls with a brush and standard household bleach might clear the surface dirt temporarily, but it leaves the living root spores untouched inside the porous render, meaning the stains return twice as thick within months. Our professional soft wash system sterilises the entire substrate, ensuring the algae is dead at the root to retard future growth for years.

Have a question about how we clean or whether we cover your area? We believe in complete transparency and want to make sure you have all the information you need before booking. Below, we have answered the most common questions we receive from homeowners, businesses, and caravan owners in Porthmadog and across North Wales.
Soft washing is a highly safe, low-pressure exterior cleaning method. It utilizes specialized, biodegradable biocide solutions applied at a pressure similar to a garden hose. We use it on render because high-pressure washing can permanently crack, chip, or delaminate through-colour render systems. Soft washing relies on chemical science rather than raw force to lift stains safely.
Yes, absolutely. With four years of industry experience, we are fully trained to clean all modern render variants, including K-Rend, silicone-based renders, monocouche, acrylic finishes, and traditional painted sand-and-cement surfaces. We adjust our cleaning solutions specifically to suit each manufacturer’s technical guidelines.
Render cleaning prices vary depending on the total surface area of the walls, the height of the property (whether scaffolding or specialized reach equipment is required), and the severity of the algae infestation. For a quick, accurate quote, message us on WhatsApp at 07900995131 with a few clear photos of your house walls.
Not at all. We take property protection very seriously. Before starting, we thoroughly pre-soak any surrounding grass, borders, or flower beds with fresh water to shield them. Once our treatment is applied, we thoroughly rinse the area down again. Our solutions dilute quickly to harmless levels, making them completely safe for your pets and landscaping.
Because our soft wash biocide treatments kill the microscopic spores deep inside the pores of the render rather than just washing the top layer, the results last significantly longer than standard pressure washing. On average, a treated render wall will remain completely clean and algae-free for three to five years, depending on tree shelter.
In the vast majority of residential projects across Porthmadog, scaffolding is completely unnecessary. Our mobile unit comes fully equipped with professional, carbon-fibre water-fed reach poles that allow us to apply treatments and safely rinse two-to-three-storey property gables directly from the safety of the ground.
