Render is a type of coating that is applied to the exterior walls of buildings. It serves as a protective layer and adds aesthetic value to the structure. However, over time, the render can become damaged due to various reasons such as weathering, cracking, or water damage, which leads to problems like dampness and structural damage if not addressed promptly.

Common Causes of Render Damage

Render damage is a common issue that can occur in buildings due to various reasons. One of the primary causes of render damage is water penetration. Water can seep through cracks, gaps or faulty seals in the render and cause it to weaken and eventually break down. This problem may be exacerbated if the building is in an area with high rainfall or humidity.

Another cause of render damage is exposure to extreme weather conditions such as frost, heat, and wind. If your building’s render has not been applied correctly, it may start to crack when exposed to these conditions. Furthermore, if the underlying structure has settled since the rendering was installed, this could also lead to cracking.

Finally, poor maintenance can also contribute to rendering damage. For example, if you neglect cleaning your rendered surfaces regularly, they may become covered by moss or other plant growths, which will penetrate the surface of the render over time, causing long-term damage.

Signs That Your Render Needs Repair

1. Visible cracks or gaps

One of the most obvious signs that your render needs repair is visible cracks or gaps in its surface. These can occur for various reasons, including weathering, settling of the building’s foundation, or poor application technique during initial installation.

2. Discoloration and stains

Another sign that your render may need repair is discolouration and stains on its surface. It can be caused by mould growth, water damage, or general wear and tear over time.

3. Bulging or warping

If you notice any bulging or warping in your render’s surface, it could indicate issues with its underlying structure. It can be caused by moisture accumulation behind the render, which creates pressure against the wall and causes it to deform.

Hiring a Professional for Render Repair

A professional renderer has the skills and expertise needed to assess any damage and provide necessary repairs. In addition, they have access to specialized tools and equipment that help them work efficiently and effectively. They also know how to mix different render materials to match the existing texture and colour of your building’s exterior.

Hiring a professional to render repair ensures that your building is safe from further damage caused by water infiltration or other environmental factors. In addition, a well-maintained building looks attractive and adds value to your property in the long run. Therefore, you must choose a reputable renderer who can provide quality workmanship at a reasonable price.


Render repair is a crucial aspect of maintaining the appearance and structure of a building. Refrain from addressing any damage or deterioration in the render can lead to further issues, such as water damage and structural problems. In addition, regular inspection and upkeep can help prevent costly repairs down the line.

Regular maintenance and repair of your building’s render is an investment in its longevity and overall value. Don’t neglect this critical aspect of upkeep – enlist the help of professionals if needed to ensure optimal results.
