How Often Should You Render Your House

House Rendering

Re-rendering your house is a renovation project that can revitalize the appearance, protect the exterior, and enhance the overall longevity of your home. While the need for house rendering depends on various factors, understanding when and why it’s necessary is essential to maintain the integrity of your property. In this article, we will explore the factors that influence how often you should consider re-rendering your house.

The Lifespan of Render

Render, the protective and decorative coating applied to your exterior walls, is not a permanent feature. The lifespan of a render varies depending on the type of render used, environmental factors, and maintenance practices.

Traditional Cement Render

Traditional cement render, when properly maintained, can last anywhere from 20 to 40 years. This type of render is known for its durability but may require more frequent maintenance.

Modern Renders

Acrylic render and silicone render, as well as other modern render systems, offer increased longevity, often reaching 30 to 50 years or more. Their flexibility and resistance to cracking and peeling contribute to their longer lifespan.


Regular maintenance is a critical factor in determining the lifespan of your render. Cracks and damage should be repaired promptly, and cleaning to remove dirt and debris is essential.

Environmental Factors

The climate and environment in which your house is located play a significant role in the need for re-rendering. Factors to consider include:

1. Climate. Harsh weather conditions, such as frequent rain, strong winds, or extreme temperatures, can accelerate the deterioration of mineral or silicone render. Wet and humid climates are particularly challenging.

2. Pollution. Houses located in areas with high pollution levels may require more frequent cleaning and maintenance to prevent the build-up of grime and pollutants.

3. Microorganisms. In humid climates, mold, mildew, and algae growth on the exterior walls can degrade the render, requiring more frequent re-rendering.

Visual Indicators

Visually inspecting your exterior walls can provide valuable insights into the condition of your render. Consider re-rendering if you observe the following signs:

  • Cracks: Cracks in the render can allow moisture to penetrate the walls, potentially leading to structural damage. Address these issues promptly.
  • Peeling or Flaking: If your lime or acrylic render is peeling or flaking, it’s a clear sign that it needs attention. This type of damage can compromise the protection provided by the render.
  • Discoloration: Discoloration, stains, or fading of the render may indicate that it is no longer adequately protecting the walls.
  • Dampness: If you notice dampness or water infiltration on your interior walls, it could be a sign of render failure and may require re-rendering.

Lifestyle and Aesthetic Considerations

In some cases, you may choose to re-render for aesthetic or lifestyle reasons. Changing the appearance of your home, updating it to match current trends, or personal preferences can also drive the decision to re-render.

Professional Assessment

To determine the precise need for re-rendering, it’s advisable to consult with a professional renderer or contractor. They can conduct a thorough evaluation of your exterior walls, taking into account the type of render, environmental conditions, and visual indicators. Their expertise can provide valuable guidance on the most appropriate timing for house rendering.


Re-rendering your house is a crucial step in maintaining its structural integrity and visual appeal. The frequency of re-rendering depends on various factors, including the type of render, environmental conditions, maintenance practices, visual indicators, and personal preferences. Regular inspections and professional assessments can help you make informed decisions about when to re-render your home, ensuring it remains well-protected and visually stunning for years to come.
