Render, Wall & House Washing

Render that has gone green, red or black makes the whole house look neglected. Soft washing kills the growth at the root and lets the true colour of your walls show through again.

What is soft washing?

Soft washing uses low pressure combined with specialist cleaning solutions, rather than relying on high-pressure water. That matters for render: blasting it can damage the surface, strip paint and force water into the wall. A soft wash kills the algae, lichen and bacteria that cause the staining, and they rinse away without harming the finish.

Surfaces we clean

  • Silicone and through-coloured render (e.g. K-Rend, monocouche)
  • Painted and pebble-dashed render
  • Brick and flint walls
  • Timber and uPVC cladding
  • Garden and boundary walls
  • Outbuildings, garages and sheds

Staining we remove

Green algae is the most common, especially on north-facing walls and near trees. Red and orange staining on modern silicone render is also a type of algae, and black streaking is usually a mix of dirt, mould and run-off. All of these respond well to the right treatment.

Our process

  • Plants, windows and doors protected before we start.
  • Cleaning solution applied at low pressure and given time to work.
  • Walls gently rinsed to remove the loosened growth and dirt.
  • Any remaining staining treated and the area left clean and tidy.

For the full front-of-house refresh, combine it with a soffit and fascia clean and a driveway clean.

Frequently asked questions

Will you use a pressure washer on my render?

No — render is cleaned using a soft-wash system at low pressure with cleaning solutions designed for the job. That protects the surface while still removing the staining.

Is soft washing safe for my plants and pets?

Plants are protected and rinsed before and after, and we'll ask you to keep pets indoors while we work. Once rinsed and dry, the area is safe to use.

How long does the result last?

Soft washing kills the growth rather than just removing the surface layer, so results typically last much longer than pressure washing alone — often several years depending on the location.
