Pigeon faeces are highly acidic and whatever surface they are deposited on will begin to break down through the corrosive action of the guano, when pigeons have taken up roosting on an area that is floored with wooden decking, the area soon becomes slippery and dangerous underfoot.
This means that people stop going out onto the balcony and so the problem intensifies, after a period of time the damage to the wood means that the decking is ruined. Sometimes we find that the birds have also nested under the decking and the wooden frame holds kilograms of pigeon poo which has rotted the subframe away as well.
In conditions like this a pigeon cleanup operation will mean taking up the top boards and its then that we find that the decking is beyond repair; we can lift the decking up, clean away all traces of pigeons and replace the entire structure as new. When combined with a properly fitted net this means that your outside space is returned to you, clean, new and pigeon free.
As licensed waste carriers all the waste material is correctly disposed of and the job is complete.
