When people think of building damage, factors like weather and age come to mind. However, pigeon poo is a surprising culprit in causing severe erosion to buildings. Understanding why pigeon droppings are so corrosive can help with preventing damage and protecting your property.
How pigeon poo damages building surfaces
Pigeon poo contains high levels of uric acid, which is incredibly corrosive. This acid content, combined with rainwater, forms a potent mixture that erodes materials like stone, concrete, and brick. Over time, this can leave stains and weaken structures. The rough surface of bricks and concrete gives the acidic droppings plenty of contact points, intensifying the impact.
As the acid seeps into tiny cracks, it gradually enlarges them, which results in the crumbling of mortar or the softening of stone. This damage often goes unnoticed until it becomes severe. In older buildings, particularly those with sandstone or limestone, pigeon poo can cause significant erosion. In more modern structures, although concrete is slightly more resistant, prolonged exposure still creates problems. The damage caused by pigeon droppings isn’t merely cosmetic; it can weaken structural integrity, necessitating expensive repairs.
How to prevent pigeon poo erosion
To protect buildings from erosion, addressing pigeon activity early on is crucial. Start by deterring pigeons from roosting on the building’s surfaces. Installing spikes, netting, or putting sloping covers on ledges and windowsills are l effective methods. Use a professional service to do this, such as our bird control team at Diamond. Pigeons prefer flat, secure surfaces for nesting, so removing their options can significantly reduce the risk of droppings.
Alternatively, ultrasonic sound devices can deter pigeons from the area without causing them harm. Regular cleaning is essential too, as it prevents the acid from penetrating deeper into the building material. Many property owners use specialised cleaning agents that neutralise the acid in pigeon droppings.
In addition to damaging buildings, pigeon poo poses health risks. The droppings often carry pathogens that can affect humans. When dried, pigeon poo can become airborne, spreading these pathogens through dust particles. This makes cleaning pigeon droppings not only a maintenance task, but also a health precaution.
