Product & Performance
How Long Does Silicone Render Last?
When professionally installed, silicone render typically lasts 20–30 years or more. Its flexibility helps prevent cracking, while its water-repellent surface protects against moisture damage — making it more durable than traditional sand and cement render.
Is Silicone Render Waterproof?
Silicone render is highly water-repellent, meaning rainwater runs off the surface rather than soaking in. However, it is also breathable, allowing trapped moisture within the wall to escape. This balance helps prevent damp issues and structural damage.
Does Silicone Render Crack?
Silicone render is far less likely to crack than traditional render. Its flexible properties allow it to move slightly with temperature changes and building movement, reducing the risk of hairline cracking. Correct preparation and professional installation are essential for long-term performance.
Does Silicone Render Need Painting?
No. The colour is built into the render finish itself, meaning it does not require repainting like traditional sand and cement render. This reduces long-term maintenance costs.
Cost & Comparison
How Much Does Silicone Rendering Cost?
Silicone rendering in Kent typically costs between £80–£140 per m². Final pricing depends on property size, wall condition, access requirements, and insulation requirements. For a detailed quotation tailored to your property, contact us for a free assessment.
Is Silicone Render Better Than Traditional Render?
Silicone render offers several advantages over sand and cement render: greater flexibility, improved crack resistance, lower maintenance, no repainting required, and longer lifespan. For most modern homes and renovations, silicone render provides better long-term value.
Installation & Process
Can Silicone Render Be Applied Over Existing Render?
In some cases, yes — but it depends on the condition of the existing surface. If the current render is stable and structurally sound, over-rendering may be possible. If it is cracked or failing, removal and proper preparation will be required. We assess each property individually before recommending the best approach.
How Long Does Installation Take?
Most residential rendering projects take between 1–3 weeks, depending on property size and weather conditions. We provide a clear project timeline before work begins.
Energy & Coverage
Can Silicone Render Improve Energy Efficiency?
Yes — when combined with external wall insulation (EWI), silicone render can significantly improve your home's thermal performance. Benefits include lower heating bills, improved comfort, reduced condensation, and better EPC rating. We can advise whether insulation would benefit your property.
