Bird droppings cleanup covers pigeon, starling and sparrow droppings on roofs, ledges, balconies, rafters and rooftops. Dry droppings can turn to fine dust, so they are wetted before they are scraped and bagged.

About 76% of homes in San Francisco were built before 1980, and older attics, vents and rooflines often have gaps where bats and birds can enter. Clarendon Heights is on the drier side, with about 21 inches of rain a year, so old guano dries out fast and turns to fine dust that must be wetted before removal.
A typical bird & bat guano cleanup job includes:
- Removal and disposal of insulation soaked with guano, urine and nesting debris
- Cleanup of pigeon and bird droppings on roofs, ledges, balconies and rooftops
- Cleanup of barns, lofts, silos, chimneys and old buildings with heavy guano buildup
- Cleanup after wildlife exclusion, once bats or birds have been removed by a professional

Bat and Bird Droppings Questions Answered in Clarendon Heights
How much does guano removal cost?
It depends on the size of the area, the depth of the deposit, how much insulation must come out and how hard the space is to reach. A small ledge costs less than a full attic. The team sets the price after seeing the space.
Can pigeon droppings damage a roof or building?
Yes. Droppings are acidic and can stain and wear down paint, metal and roofing over time. They also clog gutters and drains and create slip hazards on walkways. Cleanup and deterrents work best together.
How do you clean pigeon droppings safely?
Wet the droppings lightly, scrape them into a bag, then wash and disinfect the surface. Wear gloves, eye protection and a mask. Large roost areas, rooftops and enclosed spaces are best left to a team.
Should I remove the bats first or clean the guano first?
The animals come out first. Wildlife professionals handle exclusion, and rules about bats can vary by species, season and place. Cleanup follows once the space is no longer in use by animals.
What if droppings are on a roof or high ledge?
Roof and high ledge work needs fall protection and care around other people. Crews can remove and wash droppings there, and a property manager or owner can set up access.
Does guano damage insulation?
Yes. Insulation soaks up droppings, urine and odor and rarely comes back clean, so soiled insulation is usually removed and replaced. A team can tell you how far the damage goes after seeing the attic.
