Sand and cement rendering is a time-tested technique that provides exceptional weatherproofing. By creating a dense, protective skin over your exterior walls, it effectively prevents moisture penetration, which is a common cause of damp and heat loss in older homes. Improving the external condition of your property is also a vital step in preparing for thermal upgrades, helping to tackle cold wall issues and supporting broader energy efficiency goals. Our team takes pride in delivering a clean, uniform finish that restores the character of your building.

Our rendering process follows strict industry standards to ensure longevity and performance. We begin by preparing the substrate, which is crucial for a strong bond. We apply an initial scratch coat, which provides a key for the subsequent layers and helps level the wall. Once dried, we apply a finishing coat, floated to your preferred texture, whether that is a smooth contemporary look or a more traditional finish. Throughout the project, we adhere to PAS 2030 requirements, ensuring that every layer is applied correctly to meet modern building regulations.

For landlords and homeowners in Cardiff concerned about MEES regulations, upgrading your external envelope is a proactive way to improve your home's EPC rating. Enhancing your wall structure can help reduce heat loss, making your property more attractive to tenants and more affordable to heat. As PAS 2030 accredited specialists, we offer professional advice on how rendering fits into your wider property maintenance plan. We work alongside our sister company, Global Plastering, to provide a seamless transition between external weatherproofing and high-quality internal finishing.
