Summers in Holly Park are milder, with July highs around 77 degrees, but guano in closed attics still dries and turns to fine dust over time. About 53% of homes in Seattle were built before 1980, and older attics, vents and rooflines often have gaps where bats and birds can enter.

A typical bird & bat guano cleanup job includes:

  • 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
  • Removal and disposal of insulation soaked with guano, urine and nesting debris
  • HEPA-filtered vacuuming and air cleaning to capture fine dust after removal

How Guano Cleanup Works in Holly Park, Seattle, WA

1. Keep everyone away

Family members, tenants, staff and pets stay out while the crew plans the work and gets into protective equipment.

2. Wet down thick deposits

Heavy or caked droppings are softened with a light mist so they can be lifted without raising dust.

3. Wet, scrape and clear

Droppings are wetted, scraped and collected, and insulation that cannot be cleaned is cut out and bagged.

4. Document and hand back

The owner receives a summary of the work for buyers, inspectors or insurers, and the area is cleared for use.

Bat and Bird Droppings Questions Answered in Holly Park

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.

How do I get rid of the guano smell?

The odor comes from droppings and urine soaked into wood and insulation, so the fix is removing the source and treating surfaces. Air fresheners only cover it. Deep stains in wood may need extra treatment.

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.

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.

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 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.
