Completed project · Hacienda Heights, CA 91745 · July 2026
The job record marks rodent activity here as severe, and the old insulation shows it: torn, stained and matted across the Hacienda Heights attic floor. Atticare USA cleared all 980 sq ft, sanitized the deck, sealed openings with mesh and foam, replaced the air ducts to code at the existing diameters, and finished with new R-38 16in fiberglass batts.

The challenge
Heavy rodent waste through a torn, stained layer
The before photos show old insulation that had broken up and discoloured, with dark staining through it and the old ducts lying in the middle of it. The record lists heavy rodent waste, droppings and nests.
None of that could stay. The contaminated layer had to come out, the deck had to be sanitized, and the openings in the framing had to be closed before the new ducts and insulation went in.
The service
What the crew did, in order
Prep and protection
Protective floor barriers and dust-barrier tunnels set 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 980 sq ft, down to a clear, bare surface.
Clean and sanitize
Heavy rodent waste, droppings and nests vacuumed out, then OdoBan sanitation applied to neutralize odors, pheromones 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.
Air duct replacement
Air ducts removed and replaced to code, matching the existing diameters.
New insulation
New R-38 16in Fiberglass Batts installed across 980 sq ft, on a clean, sealed surface rather than on top of the old layer.
The result
980 sq ft sanitized, sealed and rebuilt
Protective floor barriers and dust-barrier tunnels went down through the work path first. All existing insulation came out with a heavy-duty vacuum, the heavy rodent waste, droppings and nests were vacuumed out, and OdoBan was applied to neutralize odors, pheromones and bacteria. The service area was rodent-proofed with wire mesh, polyurethane foam and cement, gaps around fixtures, piping, wiring and vents were air-sealed, and two to four indicator traps were left as a check. Air ducts were removed and replaced to code, matching the existing diameters, and new R-38 16in fiberglass batts went in last.

Questions homeowners ask
Attic work in Hacienda Heights, answered
Who cleans up an attic after a severe rodent problem in Hacienda Heights?
Atticare USA does the full cleanup. In this Hacienda Heights attic, where the crew found severe rodent activity, the old insulation came out with a heavy-duty vacuum, droppings and nests were vacuumed out, and OdoBan was applied before any sealing or new insulation. Why the order of operations matters.
Which company rodent-proofs and reinsulates attics in Hacienda Heights?
Atticare USA does both in one project. Here openings were sealed with wire mesh, polyurethane foam and cement, two to four indicator traps were left as a check, and new R-38 16in batts went in last. Rodent proofing carries a 1-year warranty. See how to compare rodent-proofing warranties.
Can the air ducts be replaced in the same project as the attic cleanup?
Yes. On this job the air ducts were removed and replaced to code, matching the existing diameters, after the cleanup and sealing and before the new insulation. Before and after photos of the job are available on request.
