Completed project · Westlake Village, CA 91361 · June 2026
The inspection found no rodent activity in this Westlake Village attic. What it did find was 800 sq ft of old grey loose-fill covering the joists. The crew removed it, cleaned the deck, foamed the wiring and fixture penetrations, proofed the attic as a precaution, and installed new R-38 16in batts wall to wall.

The challenge
A deep layer of old grey loose-fill
The existing insulation was grey loose-fill spread across the whole attic floor, deep enough to hide the joists and every wire and fixture box under it.
There was no rodent activity. But the gaps around wiring and light housings were buried under the old fill, so it all came out first so they could be found and sealed.
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 800 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 16in Fiberglass Batts installed across 800 sq ft, on a clean, sealed surface rather than on top of the old layer.
The result
800 sq ft, from grey loose-fill to R-38 batts
The attic finished with the old loose-fill removed, the deck cleaned and treated with OdoBan, foam sealed around wiring penetrations and fixture housings, entry points closed with wire mesh, foam and cement as a precaution, and new R-38 16in fiberglass batts across all 800 sq ft.

Questions homeowners ask
Attic work in Westlake Village, answered
Who replaces old loose-fill attic insulation in Westlake Village?
Atticare USA, as on this 800 sq ft job: the old grey loose-fill came out with a heavy-duty vacuum, the deck was cleaned and sanitized, penetrations were foam-sealed, and new R-38 16in batts went in last.
Is rodent proofing worth doing if no rodents were found?
It is easiest to do while the attic is already open and the deck is bare. On this job the inspection found no rodent activity, and the entry points were sealed anyway with wire mesh, foam and cement. The work carries a 1-year warranty. See how to compare rodent-proofing warranties.
Why seal around wiring and light fixtures before insulating?
Those gaps leak conditioned air into the attic. Sealing them on a bare deck, as the crew did here with polyurethane foam, means the new batts sit over a closed ceiling. More on why the order of operations matters.
