To the left: Galvanized steel meshing can be used to prevent pigeons entering drainage gullies and handrail lower cavities and making their nests and contaminating the entire balcony with pigeon guano. Pigeon meshing is a robust alternative measure when pigeon netting cant be installed successfully.
The example to the right: We have installed galvanised steel mesh to the cladding as pigeon were getting trapped in the small drainage gap and dying, causing unwanted odours and fly issues in the property. Cleaning the pigeon guano and proofing the lower cladding was recommended in this installation.
Roof top air conditioning ducting has been pigeon proofed to prevent the pigeons nesting and colonising on the roof top, causing serous contamination within the machinery from pigeon guano.
