Beyond health concerns, bird droppings cause extensive physical damage. The acid eats away at whatever surface it contacts. Limestone, sandstone and marble all deteriorate rapidly when covered in bird dropping deposits.

Pigeon droppings can block gutters and drains, leading to water damage throughout your building. When gutters fill with waste and nesting debris, rainwater overflows and seeps into walls. This creates damp problems and internal leaks that cost thousands to repair. Proper maintenance of drainage systems can help in preventing pigeon-related issues such as blockage from guano.

The weight of accumulated material stresses supporting structures. In severe cases, we have seen ceiling joists sag under hundreds of kilograms of dried droppings. Blocked gutters also become mosquito breeding sites, adding another pest problem to your property.

Guano creates serious slip hazards on walkways and steps due to its slippery texture when wet. Business owners face potential liability if customers or staff suffer injuries. Window ledges covered in waste block natural light and look unprofessional to visitors.
