If you have rendered walls on your property, you may have noticed some unpleasant algae stains that ruin the appearance of your exterior. These stains can be green, red or black and are caused by moisture and organic matter. You may think that the only way to get rid of them is to repaint your walls or use a pressure washer, but both of these methods can be costly and damaging to your render. Fortunately, there is a better solution: render cleaning. Render cleaning is a gentle and effective way to remove algae stains from your walls without harming the surface or the environment. It uses specially formulated biocides and soft-washing techniques that kill the algae and restore the original colour of your render. Render cleaning can save you money and time and make your property look as good as new.
