Common Questions

Find clear answers to frequent inquiries about our commercial window cleaning services, helping you make informed decisions with confidence.

    Soft washing is a low-pressure cleaning method using specialist solutions to kill organic growth at the root, providing a longer-lasting clean without damaging render.

  • Is render cleaning safe for all surfaces?

    Yes, when carried out correctly. We use the appropriate methods and treatments to safely clean different types of render without causing damage.

  • Do you work on large commercial buildings?

    Yes, we provide render cleaning for commercial and industrial properties of all sizes, including multi-storey and large-scale developments.
