24th August 2023

As a property owner or manager, it is important to keep the exterior of your building in top condition. One aspect of maintaining your building’s exterior is ensuring that the render is clean and free from dirt, grime, and algae. In this blog post, we will discuss the top 5 signs that indicate your building’s render needs professional cleaning. By recognizing these signs, you can take the necessary steps to keep your building looking its best.

1. Discolouration:

One of the most common signs that your building’s render needs professional cleaning is discolouration. Over time, dirt, pollution, and algae can accumulate on the surface of the render, leading to a dull and discoloured appearance. If you notice that your building’s render has become darker or is no longer the vibrant colour it once was, it is a clear indication that it is time for a professional cleaning.

2. Stains and Marks:

Another sign that your building’s render needs attention is the presence of stains and marks. Whether it is from bird droppings, water runoff, or other environmental factors, stains can be unsightly and diminish the overall appearance of your building. Professional render cleaning can effectively remove these stains and marks, restoring the render to its original condition.

3. Algae Growth:

Algae growth is a common problem on render surfaces, especially in areas with high humidity or damp conditions. If you notice green or black patches or streaks on your building’s render, it is a clear indication of algae growth. Not only does this detract from the aesthetic appeal of your building, but it can also lead to further damage if left untreated. Professional render cleaning can effectively remove algae and prevent its regrowth, ensuring that your building remains in pristine condition.

4. Cracks and Damage:

Cracks and damage to the render can also be signs that it is in need of professional cleaning. Over time, weather conditions, temperature changes, and ageing can cause the render to crack and deteriorate. This not only affects the appearance of your building but also compromises its structural integrity. By addressing these cracks and damage through professional cleaning and repairs, you can prevent further deterioration and extend the lifespan of your render.

5. Lack of Maintenance:

If you have neglected the maintenance of your building’s render for an extended period, it is likely in need of professional cleaning. Regular cleaning and maintenance can prevent the buildup of dirt, grime, and algae, keeping your render looking fresh and vibrant. However, if you have not kept up with this maintenance, it is important to seek professional help to restore your render to its original condition.


Maintaining the cleanliness and condition of your building’s render is crucial for its overall appearance and longevity. By recognizing the signs that indicate your render needs professional cleaning, you can take proactive steps to ensure that it remains in top condition. Whether it is discolouration, stains, algae growth, cracks, or a lack of maintenance, professional render cleaning can effectively address these issues and restore your render to its original condition.
