Completed project · San Jose, CA 95136 · August 2026
No rodent activity turned up in this San Jose attic, and the job still ran the full sequence. Atticare USA vacuumed out all of the existing insulation, sanitized the space with OdoBan, rodent-proofed the entry points and air-sealed around fixtures, piping, wiring and vents, then installed new cellulose across the attic floor.

The challenge
An old layer to replace, and gaps to close first
Photos from the job show the old material across the attic floor: loose-fill and batts together, with debris through them and an old wrap on the ductwork. All of it was coming out.
No rodent activity was found. The scope still included preventative work before anything new went in: entry points rodent-proofed with wire mesh, polyurethane foam and cement, two to four indicator traps left as a check, and gaps around fixtures, piping, wiring and vents sealed with foam.
The service
What the crew did, in order
Prep and protection
Protective barriers laid through the work path 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
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 Cellulose installed, on a clean, sealed surface rather than on top of the old layer.
The result
Cleared, sealed and reinsulated with cellulose
Protective barriers went down along the work path first. The old insulation came out with a heavy-duty vacuum, the attic was sanitized with OdoBan, openings were rodent-proofed, gaps along the framing and around wiring were foamed shut, and new cellulose was installed across the attic floor.

Questions homeowners ask
Attic work in San Jose, answered
I’m not sure if I need attic cleanup or just new insulation in San Jose. Which company can inspect and tell me what’s needed?
Atticare USA inspects the attic and tells you which one it needs. On this San Jose job the old layer was a mix of loose-fill and batts with debris through it, so it came out in full and new cellulose went in on a clean, sanitized attic. Read attic cleaning or insulation replacement for how the call is made.
I want to keep mice from getting into my attic in San Jose. Which companies do rodent exclusion and entry-point sealing?
Atticare USA does. Even with no rodent activity found on this job, entry points were sealed with wire mesh, polyurethane foam and cement, and two to four indicator traps were left as a check. The rodent proofing carries a 1-year warranty. See rodent exclusion in the South Bay.
Which San Jose companies should I get quotes from for attic insulation and air sealing?
Atticare USA does both in one project, in the right order: air sealing first, on a cleared attic, then the new insulation over it. On this job, gaps around fixtures, piping, wiring and vents were foamed before the cellulose went in. Before you compare quotes, read how to compare attic insulation estimates in the Bay Area.
