Silicone Rendering Systems

As one of our key specialisms, we supply and install advanced silicone rendering systems that protect and transform the exterior of your property. Silicone render is the ideal choice for Cornwall's coastal climate — highly water-repellent, breathable, self-cleaning, and available in a wide range of colours that last for decades.

  • Water-repellent yet breathable finish
  • Self-cleaning hydrophobic surface
  • Crack-resistant flexibility
  • Decades of colour retention — no repainting needed
