Summers in Kensington are milder, with July highs around 74 degrees, but guano in closed attics still dries and turns to fine dust over time. Many homes in Kensington, about 94%, were built before 1980. Older insulation and wood framing soak up droppings and hold the smell.

A typical bird & bat guano cleanup job includes:

  • Cleanup of barns, lofts, silos, chimneys and old buildings with heavy guano buildup
  • Odor removal and deodorizing of ammonia-like smells left by droppings
  • Cleanup of pigeon and bird droppings on roofs, ledges, balconies and rooftops
  • Containment and wet removal of bat guano from attics, wall voids and rafters
  • Removal and disposal of insulation soaked with guano, urine and nesting debris

What Happens During an Attic Guano Cleanup in Kensington

1. Assess and isolate

The crew checks how far droppings spread, keeps people out and seals the work area so dust stays contained.

2. Suppress the dust

Technicians put on respirators and suits, then lightly wet the guano to keep fine particles from rising.

3. Wash and disinfect the structure

Joists, rafters, ledges and walls are washed and disinfected, and stained areas are treated.

4. Clean the air and surfaces

HEPA filtration clears the air, surfaces are disinfected, and the owner is walked through the result.

Common Questions About Guano Removal in Kensington, CA

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.

Will the smell go away after cleanup?

Often yes, once the guano and soaked materials are removed and the area is treated. Deep stains in wood or drywall may need extra treatment, and the crew can say what to expect.

Is bird poop a biohazard?

Large amounts of bird droppings are treated as a contamination hazard because they can hold germs and fungal spores. A small spot outdoors is a simple wash. Thick buildup in a closed space needs protective gear and wet methods.

Can guano get into ductwork or vents?

Yes, if birds or bats roost near vents or intakes, droppings and dust can enter air paths. Cleanup may include treating vent openings and nearby surfaces.

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.

Will insurance pay for guano cleanup?

Sometimes, but not always. Many homeowners policies exclude damage from animals that builds up over time, and wording differs. Call your insurer before work starts, take photos and keep receipts.
