This study has provided significant insight and understanding in to what is causing your render to discolour, whether it is green, red or black algae blooms. We are proud to be recommended by K-Rend themselves, and our render cleaning solutions will not invalidate your K-Rend warranty. For render cleaning we only use eco-friendly biocides combined with a non aggressive method developed for the treatment of roofs and walls called Softwashing. The Softwashing system and equipment combined with specialised training allows our team to deliver the chemicals effectively and safely every time. We guarantee a deep clean of your render, leaving it in the best physical condition, free from both organic growth and any discolouration. Whether you need a full clean of your building’s exterior render or localised cleaning for the removal of unsightly stains, we are happy to help.
