Islington Council asked us to chemically clean and remove all evidence of pigeon guano that had built up over a long period. We set about the task with a schedule of 3 days to clean 3 water tank rooms of all the pigeon droppings. Pressure washing all areas and spraying with avian disinfectant so it could be safely removed off site and disposed of in accordance with current health and safety guidelines. Project completed within the time frame with before and after videos sent to the client as is standard with all our pigeon guano cleaning projects.
