Render Cleaning Cardiff

Whilst newly built k-render buildings look fantastic the UK climate can rapidly degrade the original coloured render finish of a building, meaning you may require render cleaning in Cardiff, Bristol or Swansea. In just a few years, your “maintenance free” rendered exterior can be covered in unsightly algae staining which will get thicker and more unsightly over time if left untreated.

Algae is a natural phenomenon and the climate in the UK is ideal to nurture its growth due to our damp and mild weather. The most common staining on k-render is “green” algae growth, but luckily this is usually the easiest to treat. If the algae staining has been left untreated for a long period these stains may turn “black” in colour and on certain elevations of buildings in many areas of the UK your building may suffer from “red” algae staining.

The good news is that we are experienced in the removal of all types of algae staining from K Render, Monocouche Render and Weber Render and can quickly and cost effectively return your building to it’s former glory with our cost effective render cleaning services.

You will not have to paint the render on your building which on large commercial buildings can save tens of thousands of pounds in expensive scaffolding costs. Our render cleaning service relies on specialist access platforms which can work on both hard standing areas and grass and can fit through the smallest of gates and alleyways which means that we can usually reach even the most awkward of buildings.

We can also, where the site dictates, apply our soft wash render cleaning chemicals from the ground which means neither scaffolding or access equipment is needed. This is often the case with domestic render cleaning on houses.

K Rend Cleaning

Before commencing work, we will visit your site so as to inspect the building and ensure that we are fully prepared for the task at hand.

We use a wide variety of render cleaning equipment to get the best results for each and every client; furthermore, since we specialise in high level work, we are able to clean tall buildings and hard-to-reach areas safely and efficiently.

Here are some of the buildings our K-Rend cleaning specialists have worked on in the past:

  • Blocks of flats
  • Office buildings
  • Warehouses and factories.

Remove Stains From Render

If the outside of your building is coated in render, you may have noticed that render is a magnet for moss, algae, and other unsightly growths. This is due to the high porosity of K-Rend and other render products.
