Warehouse cleaning

We recently cleaned the exterior of a huge warehouse as part of a refurbishment project. Work included cleaning external metal clad walls, yellow metal roller doors and brickwork. The unit had been out of use for some time and the exterior surfaces were covered in black and green algae and lichen, making it look very much the worse for wear. All exterior surfaces needed to be thoroughly cleaned and made ready for painting.

Algae - a perennial problem 

Algae spores are airborne; when they land on an exterior surface all they require to grow and flourish is moisture. Hard exterior surfaces, such as stone, concrete, brick or metal, located in damp, shady places are all vulnerable to contamination. Although growth tends to be more significant in autumn and winter, it can happen in any season if the surface is persistently damp and shady. As you can see from the pictures below it creates unsightly stains, moreover it can contribute to more rapid degeneration of the surface material.

A belt and braces approach gets the best results

Algae can be challenging to remove but OneFifty’s tried and tested cleaning process always achieves the best possible results.

  • First we clean the surface using SteamPLUS, pressurised steam heated to 150 degrees, which delivers powerful cleaning whilst still being gentle on the surface material. 
  • Next we apply our own chemical wash specifically developed to tackle algae staining which ensures the final pass with SteamPLUS will remove all trace of the algae and leave the surfaces really clean.
  • We can also apply a OneFifty inhibitor developed to deter future growth and keep the building exterior looking clean and fresh for as long as possible.

Pressurised steam achieves a brilliant outcome

Our team worked really hard to make sure that the cleaning of this huge unit was completed to a high standard and on deadline. Every exterior surface was left looking really clean and fresh - without a trace of algae, lichen or any other contaminant.

The property managers were delighted with the outcome, the reburbishment has now been completed ready for the new tenants to move in.
