Professional External Rendering & Insulation Solutions
Serving London and the Home Counties
At Fastset Ltd, we provide external rendering and insulation solutions to transform and protect your property. Our team specializes in durable exterior finishes, including high-performance silicone render systems designed to withstand the elements.
Whether you need to improve energy efficiency through wall insulation or simply want to refresh your home's look, we are the rendering specialists you can trust.
Exterior Rendering Solutions
Silicone render is our most recommended finish because it is hydrophobic, breathable, and highly resistant to cracking. It is a superior choice for external rendering projects compared to traditional systems.
While we specialise in silicone systems, we are also able to adapt our services to your preferences or needs.

Structured, Professional Process
From assessment to completion, we follow a clear, methodical approach. This means no rushed jobs, no shortcuts, and consistent results you can rely on.
Clear Timelines & Communication
We keep you informed throughout the project, explaining the process and timelines clearly so there are no surprises along the way.
Our rendering systems include a 10-Year Guarantee for long-term protection and peace of mind.
