External Rendering Services in Johnstone

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 Johnstone 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.

The best render depends on your property type, wall material, and aesthetic goals:

• Silicone render: Flexible, breathable, water-repellent—ideal for modern homes.
  
  
• Acrylic render: Durable and comes in a wide range of colours.
  
  
• Monocouche render: Low-maintenance, decorative finish in a single coat.
  
  

Lime render: Breathable—perfect for older or heritage buildings.
We can advise you on the most suitable option during your site visit.

Costs vary based on the render type, surface area, and site conditions. On average:

• Sand & cement: £40–£60 per m²
  
  
• Monocouche: £50–£70 per m²
  
  
• Silicone/acrylic: £55–£80 per m²

Rendering is best done in mild, dry conditions. However, we use specialist additives and techniques that allow us to work in slightly cooler temperatures. Rain and freezing conditions are generally avoided as they can affect curing. We always schedule work with weather forecasts in mind to ensure a lasting finish.
