Completed project · Los Angeles, CA 91306 · February 2026
White loose-fill heaped between the joists, and matted brown batts in other sections: two kinds of old material lined this 1,560 sq ft Los Angeles attic. Atticare USA cleared both down to the bare deck, sanitized it, sealed fixtures and vents with foam and wire mesh, and installed new R-38 16in fiberglass batts.

The challenge
Two kinds of old insulation to clear before anything new
The before photos show old white loose-fill spread across the joists and piled around the duct runs, with matted brown batts in other sections. The job record lists rodent waste, droppings and nests among the material to clear, but does not record how much activity the crew found.
Laying new batts over the top would have sealed all of that in. So the attic was emptied to the deck first, which also exposed the gaps around fixtures, wiring and vents that needed sealing before any insulation went back in.


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 across 1,560 sq ft, 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 16in Fiberglass Batts installed across 1,560 sq ft, on a clean, sealed surface rather than on top of the old layer.
The result
1,560 sq ft, cleared to the deck and rebuilt in R-38
Floor protection and dust barriers went in at the access point first. The old insulation came out with a heavy-duty vacuum, rodent waste, droppings and nests were vacuumed out, OdoBan was applied 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 16in fiberglass batts went in last, and two to four indicator traps were left as a check.

Questions homeowners ask
Attic work in Los Angeles, answered
My attic smells bad and I think rats may have been in there. What kind of company should I call in Los Angeles?
An attic restoration company such as Atticare USA, with a licensed pest control provider first if animals are still active. Odor tends to stay in the old insulation, so on this Los Angeles job the whole layer came out with a heavy-duty vacuum, rodent waste was vacuumed out, and OdoBan was applied to neutralize odors, pheromones and bacteria before any new work began.
I had rodents in my attic and need the insulation removed, the space cleaned, and new insulation put in. Who does that in Los Angeles?
Atticare USA does all three as one project. Here the crew cleared 1,560 sq ft to the deck, sanitized it, sealed the openings, and installed R-38 16in fiberglass batts last. Why the order of operations matters.
Rats keep getting back into my attic in Los Angeles. Which companies seal up the entry points they use?
Atticare USA seals entry points with wire mesh, polyurethane foam and cement, and on this job also foam-sealed around fixtures and vents on the cleaned deck. Two to four indicator traps were left as a check, and the rodent proofing carries a 1-year warranty. See how to compare rodent-proofing warranties.
