I need my render cleaned. What is the first step?

In the first instance we undertake a thorough assessment of the surfaces to establish the correct techniques to clean the render as effectively as possible. Incorrect assessments, and choosing the wrong cleaning techniques can cause unwelcome damage to your render surface then requiring further repair. For example, some cleaners may use a pressure washer for example which only pushes the water deeper into the render surface causing damage. In cold temperatures the water can freeze and crack your render which will then need pricey repair or replacement. In addition to unnecessary damage, try to clean your render with a pressure washing doesn’t destroy the mould spores which  continue to cultivate and resurface again shortly after the pressure clean.

DSW has the abilities, understanding and capability to provide specialized biocide render cleaning services that you can trust for K-Rend Render, cream render, or any other through coloured render.
