Specialist in Removing Red Stains From External Walls

Take a look at our Before and After pictures.
We use a technique known as soft washing, which is ideal for a variety of render surfaces, like pebble dash, monocouche (K-Rend, Webber, Fassa), thin coat acrylic, sand cement mix, wet dash and painted surfaces. Our tailored approach allows us to customize the chemicals we use based on the specific surface at hand.
We will clean the outside surfaces of your property, starting from the outside of the gutter, fascia's, and external render down to the ground, ensuring every aspect is spotless.
Step 1- Our expert team will treat the walls using our specialized chemical mix, effective in killing and removing mould, algae, and other organic stains from the surface.
Step 2- We will use low pressure to safely rinse off the chemicals from the walls without damaging the finished surface.
Step 3- We will repeat the process as necessary until we achieve the desired result making a noticeable difference to your property’s appearance.
Before we leave, we will ensure that any remnants of chemicals are rinsed away from windows, doors, steps, driveways, paths, and other surfaces, leaving your property safe, clean, and tidy.
We fully guarantee that we will not cause any damage to your property or its surroundings.
