External rendering involves applying a protective and decorative coating to the exterior walls of a building. It improves the property’s appearance, adds weather resistance, enhances thermal performance, and protects against water ingress, cracks, and environmental damage. It’s especially important in the Hertfordshire climate to maintain structural integrity and boost curb appeal.
The lifespan of external render depends on the type used and the quality of application. Traditional sand and cement renders last around 15–20 years, while modern silicone or monocouche renders can last 25–30 years or more with proper maintenance. Regular inspections help extend render life.
