Oceanview 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. 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.
Bird & Bat Guano Cleanup in Oceanview usually includes:
- Removal and disposal of insulation soaked with guano, urine and nesting debris
- Containment and wet removal of bat guano from attics, wall voids and rafters
- Cleanup of barns, lofts, silos, chimneys and old buildings with heavy guano buildup
- Sorting, cleaning and sanitizing of stored items and belongings that can be saved
- Documentation of the work for buyers, inspectors, landlords and insurers

Guano Cleanup Frequently Asked Questions in Oceanview, San Francisco, CA
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.
What rules apply to guano cleanup in California?
Worker safety follows OSHA rules for hazardous dust, and waste disposal is handled according to local requirements. Rules about moving or excluding bats and other wildlife can vary by species and season, so check with a wildlife professional first.
Do I need to replace attic insulation after guano?
Usually, if droppings or urine have soaked into it. Soiled insulation holds contamination and odor and cannot be reliably cleaned. After removal, new insulation is installed as a separate job.
Is guano dangerous?
It can be. Dry guano releases fine dust, and some bird and bat droppings can carry a fungus linked to histoplasmosis, a lung infection. Many people never get sick, but older, heavy deposits carry more risk. Avoid stirring it up.
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.
Do barns and old buildings need special handling?
Buildings with years of buildup can hold thick, dry, dusty guano that is easy to disturb. Crews ventilate, wet down and use respirators and containment to keep spores out of the air.
