Render cleaning

Tired render? Bring it back to life

Green algae, black streaks and weathering can make even a good render look tired. Here on the edge of the Pennines, with plenty of rain and little sun on north-facing walls, it doesn't take long for organic growth to take hold. Transform Render Systems & Building Services now offers specialist render cleaning and restoration, using professional low-pressure softwashing to bring your walls back to their original colour.

Softwashing is the safe way to clean render. Rather than blasting the surface with a pressure washer – which can damage the finish, strip the texture and force water into the wall – we apply specialist cleaning solutions at low pressure that break down algae, lichen and organic staining, then rinse the render clean. Because it treats the growth itself rather than just the surface, your render stays cleaner for longer.

We have invested in a high-spec softwash machine so we can do the best job possible, efficiently and safely, for every client. And after more than 20 years applying render as K Rend approved applicators, we know how Weber, K Rend, silicone and monocouche systems are made – and how to clean them without causing damage.

Regular maintenance helps keep biological growth under control and avoids the need for more intensive cleaning later, so ask us about keeping your render looking its best.

Our render cleaning service covers:

  • Green algae, moss and lichen removal
  • Black streaking and organic staining
  • General weathering and grime
  • Weber, K Rend, silicone and monocouche renders
  • Homes and commercial buildings
  • Regular maintenance cleans

We're based in Colne and cover most of the North West, including Burnley, Nelson, Barrowford, Barnoldswick, Clitheroe and Skipton. If your render is cracked or failing rather than just dirty, our rendering team can repair or replace it.

How it works

Our render cleaning process

  1. 01

    Survey & quote

    We check the type of render, the staining and the access, then give you a clear, no-obligation price.

  2. 02

    Protect

    Windows, doors, plants and the areas around your property are protected before any cleaning starts.

  3. 03

    Softwash

    Render-safe cleaning solutions are applied at low pressure and left to break down algae and organic growth.

  4. 04

    Rinse & finish

    A gentle rinse leaves an even, clean finish. Any faint staining left behind continues to fade over the following weeks.

FAQs

FREQUENTLY ASKED QUESTIONS

Can't see your question? Call us on 07849 496810 or send us a message and we'll get back to you.

Will softwashing damage my render?

No. Softwashing uses low pressure and specialist cleaning solutions made for render, so it cleans without eroding the surface or stripping the texture. It's the approach we recommend for modern renders such as Weber, K Rend, silicone and monocouche.

Why not just pressure wash the render?

High-pressure washing can erode the surface, strip the texture, force water into cracks and damage the water-repellent finish of silicone renders. It also tends to remove only the visible growth, so the algae soon comes back. Softwashing treats the growth itself at low pressure, which is safer for the render and gives a longer-lasting result.

How long will my render stay clean?

It depends on which way the walls face, nearby trees and how exposed the property is. Because softwashing treats the growth rather than just blasting off the surface, the results last longer than a pressure wash. Regular maintenance helps keep biological growth under control and avoids the need for more intensive cleaning later.

Do I need scaffolding for render cleaning?

Not usually. Our softwash system works from the ground using extendable reach poles, which keeps costs down for most properties. For very tall or awkward elevations we'll talk you through the access options when we quote.

Do you clean render on commercial buildings?

Yes. We clean render on homes and commercial properties alike – the before and after photos on this page are from a commercial building and café.

How much does render cleaning cost?

It depends on the size of the property, the type of render, how heavy the staining is and access. We give free, no-obligation quotes – call 07849 496810 or send us a message with a few details.
