Completed project · Berkeley, CA 94709 · June 2026
No rodent activity turned up in this 600 sq ft Berkeley attic. What needed fixing was the old tan loose-fill spread between the joists and under the plywood boards. The crew removed all of it, cleaned and sanitized the deck, air-sealed the gaps, screened the vents with wire mesh as a precaution, and installed new insulation across the attic.

The challenge
Old loose-fill, and no rodents in it
The inspection found no rodent activity. The existing loose-fill was old and uneven, spread unevenly between the joists and under the plywood boards laid across part of the floor.
A rodent-free attic still has gaps around fixtures, wiring and vents. Removing the old layer first let the crew clean the deck, seal those gaps and screen the vents before the new insulation went in.
The service
What the crew did, in order
Prep and protection
Floor protection and dust barriers set at the access point before any material was moved, so the rest of the house stayed clean.
Remove the old insulation
The existing insulation taken out with a heavy-duty vacuum across 600 sq ft, down to a clear, bare surface.
Clean and sanitize
Dust and debris vacuumed out, then OdoBan sanitation applied across the work area.
Seal and rodent-proof
Preventative rodent proofing: likely entry points closed with wire mesh, polyurethane foam and cement, though no rodent activity was found. Gaps around fixtures, piping, wiring and vents air-sealed in the same pass.
New insulation
New insulation installed across 600 sq ft, on a clean, sealed surface rather than on top of the old layer.
The result
600 sq ft, from old loose-fill to a clean, sealed deck and new insulation
The attic finished with the old loose-fill removed, the deck cleaned and treated with OdoBan, gaps around fixtures, piping, wiring and vents air-sealed, the vents screened with wire mesh, and new insulation installed across all 600 sq ft.

Questions homeowners ask
Attic work in Berkeley, answered
I want to stop mice from getting back into my attic in Berkeley. Which companies do rodent exclusion and entry-point sealing?
Atticare USA seals entry points with wire mesh, polyurethane foam and cement and leaves two to four indicator traps as a check. On this Berkeley job there was no rodent activity, and the vents were still screened as a precaution. The rodent proofing carries a 1-year warranty. More on sealing, cleaning and reinsulating in the East Bay.
My Berkeley attic has no rodents, just old insulation. Do I need attic cleaning or only new insulation?
A free inspection answers that. Here the inspection found no rodent activity, so the job was a straight replacement: old loose-fill out, deck cleaned and sealed, new insulation in. See attic cleaning or insulation replacement.
