Documentation of the work for buyers, inspectors, landlords and insurers
Disinfection of wood framing, joists and hard surfaces with EPA-registered products
Removal of nests, feathers and carcasses left by birds or bats
Commercial guano cleanup on warehouses, storefronts, loading docks and parking structures

Step by Step: Safe Guano Removal in Brentwood, CA

1. Safety first

2. Suppress the dust

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

3. Take out contaminated material

Guano, matted insulation and nesting debris are packed out, and salvageable items are set aside for cleaning.

4. Disinfect and inspect

Wood, drywall and hard surfaces are cleaned and disinfected, odor is treated, and the crew checks the finished space.

Guano Cleanup Frequently Asked Questions in Brentwood, CA

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.

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.

Can you get sick from bat droppings?

Yes, mainly from breathing in dust from dry droppings. Risk is higher with old, heavy buildup in enclosed spaces. People with asthma, lung conditions or weak immune systems need extra care and should stay out of the area.

What should I do first if I find guano?

Do not sweep, blow or vacuum it. Keep people and pets away and leave it undisturbed until you know the size of the job. Call Brentwood Biohazard Cleanup Help at (877) 812-4220 to talk through the safest next step.

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.

What is histoplasmosis?

Histoplasmosis is a lung infection linked to a fungus that can grow in soil and droppings from birds and bats. People are exposed by breathing in spores. Many exposed people have no symptoms, and anyone who feels unwell after being around guano should tell a doctor.
