Algae removal - San Lorenzo Court, Cornwall

San Lorenzo Court is a contemporary development of one and two bedroom retirement apartments located in St. Ives overlooking Carbis Bay. The attractive, modern building exterior features a combination of natural grey Cornish slate, local stone and a K Rend render. The render – usually the colour of Cornish clotted cream - had become stained with unsightly black algae. This is a hazard of being near to the sea as the algae thrives in a damp atmosphere and, as is to be expected, the walls to the rear of the building and any recessed areas that do not get much direct sun were particularly affected.

Our tried and tested three-step process gets the best results

Algae can be challenging to remove but we know that our tried and tested three-step process will get the best possible results.

1. First we clean the surface using steam cleaning; pressurised steam heated to 150 degrees delivers powerful cleaning whilst still being really gentle on the render surface.

2. Next we apply a gentle chemical agent that we have specifically developed to tackle algae staining, this ensures that the final pass with steam cleaningwill completely remove all trace of the algae taking the render back to its original soft cream colour.

3. Finally, since algae is persistent, we apply a growth inhibitor to deter future growth and keep the building exterior looking clean and fresh for as long as possible.

Careful attention to detail ensures successful outcome 

San Lorenzo Court is surrounded by pretty landscaped areas with mature shrubs, flowers and lawns. We have plenty of experience of cleaning residential properties and know how important it is to avoid damaging plants by taking extra care when installing access equipment.

Clear communications with residents

Many of the apartments have spacious balconies with smoked glass panelling so it was important to make sure residents were fully aware of exactly when the cleaning would be taking place, and that they remove any outdoor furniture or other items from their balconies until the cleaning work had been completed. Clear communications with the residents, followed up by careful checking in advance of carrying out the cleaning, helped ensure that nothing was damaged. We also made sure that our team cleaned the glass panels leaving them gleaming.

San Lorenzo Court looks wonderful now that we have completed the cleaning and the residents are delighted with the outcome. The before and after images below show what a difference our cleaning has made.
