Completed project · San Jose, CA 95125 · July 2026
Grey loose-fill sat heaped around the ducts and plumbing of this 600 sq ft San Jose attic. The inspection found no rodent activity, so the job was a straight replacement: everything vacuumed out, gaps around fixtures, piping and wiring air-sealed, entry points proofed as a precaution, and new R-38 24in fiberglass batts laid in.

The challenge
Old loose-fill piled around ducts and plumbing
The existing loose-fill was grey and uneven, piled up around the ductwork and pipes that run through the attic, and was doing little for the rooms below.
The inspection found no rodent activity. Even so, the crew took the old layer out rather than adding to it, so the deck could be cleaned and the gaps around fixtures, piping and wiring sealed before the new batts went in.
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 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 R-38 24in Fiberglass Batts installed across 600 sq ft, on a clean, sealed surface rather than on top of the old layer.
The result
600 sq ft, cleared and rebuilt in R-38 batts
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, entry points closed with wire mesh, foam and cement, and new R-38 24in fiberglass batts across all 600 sq ft.

Questions homeowners ask
Attic work in San Jose, answered
The inspection on my San Jose home flagged old, dirty attic insulation. Which company should I call for cleanup and new insulation?
Atticare USA handles both as one project. On this San Jose job the old loose-fill came out with a heavy-duty vacuum, the deck was cleaned and sanitized, gaps were air-sealed, and new R-38 24in batts went in on the clean deck. See attic cleaning or insulation replacement.
Which San Jose companies should I get quotes from for attic insulation and air sealing?
Atticare USA does both together, in the right order: air sealing around fixtures, piping, wiring and vents on the clean deck first, then the insulation over it, as on this 600 sq ft attic. Before you compare, read how to compare attic insulation estimates in the Bay Area.
If there are no rodents, does the old insulation still need to come out?
Not always. Clean, intact insulation can be added to. Here the inspection found no rodent activity, but the old loose-fill was grey and uneven, so it came out and the attic was sealed before the new batts went in. A free inspection will tell you which your attic needs.
