Completed project · San Leandro, CA 94578 · April 2026
Deep white R-38 blown-in insulation now fills this San Leandro attic, where old batts and loose-fill used to be. Atticare USA took the old layers out with a heavy-duty vacuum, sanitized the bare deck with OdoBan, rodent-proofed and air-sealed the attic, and blew in the new layer last.

The challenge
Two old layers, both past their use
The before photos show two kinds of old material: yellow batts pulled loose and broken up in one area, and grey loose-fill with debris in another.
Blowing new insulation over that would have buried the old material and whatever was in it. The job cleared the attic to a clean deck first, then sealed it, so the new layer sits on a sanitized, closed attic.
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, down to a clear, bare surface.
Clean and sanitize
Debris vacuumed from hard surfaces, then OdoBan sanitation applied to neutralize odors and bacteria.
Seal and rodent-proof
Entry points closed with wire mesh, polyurethane foam and cement, with two to four indicator traps left as a check. Gaps around fixtures, piping, wiring and vents air-sealed in the same pass.
New insulation
New R-38 Blown installed, on a clean, sealed surface rather than on top of the old layer.
The result
Old layers out, R-38 blown-in on a clean deck
Floor protection and dust barriers were set at the access point. All existing insulation came out with a heavy-duty vacuum, the deck was vacuumed and sanitized with OdoBan to neutralize odors, pheromones and bacteria, the service area was rodent-proofed with wire mesh, polyurethane foam and cement, and gaps around fixtures, piping, wiring and vents were air-sealed. New R-38 blown-in insulation went in last, with two to four indicator traps left as a check.
