K-Rend, monocouche, pebbledash - safely restored using softwash to remove algae and staining.
Rendered walls are prone to algae, moss, and atmospheric staining, particularly on north-facing elevations. High pressure can cause significant damage, which is why our render cleaning services rely exclusively on specialist softwash treatments. We provide expert render cleaning in the North East that kills organic growth at the root and lifts staining without forcing water through the surface. Our use of biocides ensures your property stays cleaner for longer, offering a safe alternative to pressure washing that protects your home from premature deterioration.
Gentle softwash cleaning that preserves the self-cleaning properties and coloured finish of silicone-based systems. Our professional approach ensures a deep clean without the risk of surface abrasion.
A low-pressure treatment to remove algae and restore colour without damaging the through-coloured surface. This is ideal for maintaining the porous texture of monocouche across the North East.
Careful cleaning to remove dirt and organic growth without stripping or fading the paint. This refreshes your property's appearance while keeping the existing finish intact.
Softwash treatment to safely remove moss, algae and staining from older rendered walls. We focus on restoring the surface without weakening the structural bond.
Deep cleaning of textured surfaces to remove embedded dirt and organic growth. Our methods reach into the gaps of the dash that standard washing often misses.
Ultra-gentle cleaning for delicate lime render on listed or period properties. We prioritise preservation to ensure heritage finishes are handled with the necessary care.
Safe cleaning of insulated render systems without damaging the finish or waterproofing. This protects both the appearance and the thermal efficiency of your home.
Specialist treatment for modern polymer-based render systems to restore their original appearance. Softwash is the perfect match for the flexible nature of polymer finishes.
Careful cleaning of textured Tyrolean render without damaging the distinctive pattern. We clear the grime while ensuring the textured depth remains unharmed.
Targeted treatment for stubborn red and orange algae staining common on rendered walls. Results develop gradually over the following weeks as the growth dies off and the staining fades with rainfall.
No. Pressure washing damages render by forcing water behind the surface, stripping the protective finish and potentially voiding warranties. We use softwash - a low-pressure chemical treatment that kills algae, moss and organic growth safely. It's approved by K-Rend and other manufacturers, and actually extends the life of your render rather than shortening it.
That's red algae, scientifically known as Trentepohlia. It's particularly common on white or light-coloured render and thrives in damp, shaded areas. We treat it using specialist biocides that kill the algae at the cellular level. Results build over the following weeks, often up to around 12–14 weeks depending on the severity of the staining and exposure to weather.
Our biocide treatments continue working for several months after application, killing regrowth as it appears. Most renders stay clean for 3–5 years depending on exposure, orientation and environmental factors. North-facing walls and properties near trees may need more frequent treatment. We can advise on realistic maintenance schedules based on your specific property.
Softwash cleaning is safe and won't void warranties - in fact, many render manufacturers recommend it as the approved cleaning method. Pressure washing, on the other hand, often does void warranties. We follow manufacturer guidelines and can provide documentation if needed for warranty purposes.
Yes, provided the paint is in reasonable condition. We use gentle softwash treatments that clean without stripping or fading the paint. If the paint is already flaking or failing, cleaning may highlight this - but that's a sign the render needs repainting anyway. We'll assess the condition before starting and advise honestly.
With standard softwash treatments on render, results build gradually. You'll usually notice an improvement within the first few weeks, but full results typically develop over 12–14 weeks as the organic growth breaks down and washes away with rainfall. Where stronger chemistry is appropriate and agreed in advance, results can be much faster and in some cases almost immediate.
