Common Cladding Problems and How to Prevent Them

Maintaining the exterior of a building is crucial for its aesthetic appeal and structural integrity. Cladding serves as a protective layer for buildings, but without proper maintenance, various problems can arise. In this article, we’ll discuss common cladding problems like mould, fading, and physical damage, along with prevention tips from leading commercial and specialist cleaners, SymClean Industrial. 

The Importance of Cladding 

Cladding is the external layer or covering of a building. Essentially serving as a protective barrier against environmental elements. It enhances the building’s appearance while providing insulation and structural support. Cladding materials range from metal and vinyl to wood and composite panels, each offering unique properties and aesthetics.

Because of this protection, cladding is crucial for maintaining the integrity and longevity of a building. It protects against weather conditions, UV rays, and temperature fluctuations, reducing wear and tear on the structure. Cladding also improves thermal insulation, enhancing energy efficiency and reducing heating and cooling costs. 

Cladding, a visual element, often enhances the visual appeal of a building. Whilst this is great for aesthetics, if not properly managed and kept, cladding could also ruin the visual appeal of your property.

There are various types of cladding solutions and systems tailored to different structures and buildings. Different types include ventilated cladding, overcladding and curtain wall cladding, all offering different benefits for properties. Materials like metal, vinyl, wood, and composite panels are commonly used in cladding, each with its unique benefits in terms of durability, aesthetics, and maintenance. 

Common Cladding Problems and How to Prevent Them

Cladding, while designed to be durable and protective, can develop problems over time due to various factors. Common causes of problems include weather exposure, moisture retention, poor installation and lack of maintenance. The environment typically plays a huge part in cladding deterioration, bad weather and pollution can be detrimental, especially when cladding is not maintained, and issues are not prevented. 

Mould and mildew

Mould and mildew growth are among the most common problems faced by both commercial and domestic property owners. These fungi thrive in moist environments and can quickly spread across the cladding surface.

The main cause of mould and mildew growth is moisture accumulation and inadequate ventilation, combined.

This cladding issue can cause an unappealing appearance. Mould also can pose health risks, which is a serious consideration when tackling cladding problems.


Fading of cladding is caused by environmental elements such as harsh weather conditions, prolonged exposure to UV rays, and pollutants. The issues caused by fading are primarily aesthetic, reducing appearance, kerb appeal and overall value.

Algae growth

Algae growth is another common cladding issue. This problem typically occurs in humid and shaded areas where moisture, shade, and organic matter accumulate. The combination of these factors creates ideal conditions for algae to thrive. 

Algae growth can make the cladding slippery, posing safety risks to occupants. To prevent algae growth, regular maintenance is essential. 


Rust is a big problem if it affects your cladding. Unfortunately, rust is not an uncommon problem, and it typically happens with metal cladding. This is another problem caused by the weather, primarily rainfall. If you find rust on your cladding, it is important to seek professional help as rust can cause structural problems. 

Physical damage

Physical damage like cracks, chips, and dents on cladding can occur due to impact from debris, extreme weather conditions, or improper installation. Physical damage can compromise the cladding’s protective barrier and lead to further, more costly damage to the building.

Prevention Tips for Maintaining Cladding Integrity

Maintaining the integrity and longevity of cladding is crucial for property owners and supervisors. Proper care and preventive measures can help avoid costly repairs and ensure the cladding continues to perform at its best. 

  1. Regular Cleaning
    Regular cleaning is essential to protect cladding and maintain appearance. Professional cleaning services can effectively remove dirt, grime, pollutants, and organic growth without causing damage to the cladding infrastructure.
  1. Proper Ventilation
    Ensuring proper ventilation is essential to reduce moisture buildup behind the cladding. Proper airflow helps prevent condensation, which can lead to moisture-related issues such as mould growth and rot. A professional assessment can help identify and improve ventilation where needed.
  1. Regular Inspections
    Regular inspections can help identify signs of damage, wear, or issues before they escalate. Early detection allows for timely intervention, minimising potential damage and extending the lifespan of the cladding.
  1. Prompt Repairs
    Repairing any damage as soon as it’s detected is crucial. This will help to prevent further deterioration and maintain the cladding’s integrity. Professional repair services address issues such as cracks, dents, or loose panels effectively, ensuring the cladding continues to provide optimal protection and aesthetics.
  1. Resistant Cladding
    Choosing resistant cladding materials can provide added protection against various issues, including pollutants, weather damage, and physical damage. It is important to work with contractors who understand the importance of this when creating structures and solutions. Investing in high-quality, durable cladding materials can offer long-term benefits and reduce maintenance needs.

Incorporating these prevention tips into your cladding maintenance strategy can help preserve the appearance, performance, and longevity of your cladding. Partnering with a professional commercial cleaning company like SymClean Industrial can ensure your cladding receives the specialised care it deserves, safeguarding your investment and enhancing your property’s value.
