Measurable Benefits, Lasting Value

Rendering & Roughcasting, Answered
Render is a general term for an external wall coating. Roughcasting (or harling) is a specific traditional finish that throws a mix of aggregate and binder onto the wall for a textured, weather-resistant surface. We deliver both smooth render and roughcast finishes.
