Completed project · Lawndale, CA 90260 · August 2026
It started, like every job here, with a free inspection — and this one turned up more than expected. 1,573 sq ft of Lawndale attic, taken back to bare joists and rebuilt. New R-38 16in Fiberglass Batts installed on a stripped, sealed deck. 2-4 indicator traps left behind to confirm the space stays clear.

The challenge
Severe rodent activity through the attic
The inspection found severe rodent activity in this Lawndale attic — droppings, nests and contaminated material across the space, with open gaps around fixtures, piping, wiring and vents that rodents were using to come and go.
Once contamination is inside the insulation layer, cleaning around it does not fix the problem: the material holds the waste, the odor and the scent trail that brings the next rodent back. That set the order of work — clear the layer, treat what is underneath, close the entry points, and only then insulate. The layer covered 1,573 sq ft.
The service
What the crew did, in order
Prep and containment
Protective floor and dust barriers set through the work path before anything was opened, so the work stayed inside the attic and out of the rest of the home.
Remove the old insulation
The existing insulation layer taken out with a heavy-duty vacuum across 1,573 sq ft, leaving bare joists and a clear view of the deck.
Clean and sanitize
Rodent waste, droppings and nesting material vacuumed out, then the surfaces treated with OdoBan sanitation to clear odor, bacteria and the scent trails that draw rodents back.
Seal and rodent-proof
Entry points sealed with wire mesh, polyurethane foam and cement, with two to four indicator traps set to confirm the space stays clear. Gaps around fixtures, piping, wiring and vents air-sealed in the same pass — the openings that leak conditioned air are usually the ones rodents use.
New insulation
New R-38 16in Fiberglass Batts installed across 1,573 sq ft, bringing the attic to current California code on a clean, sealed deck rather than on top of the old layer.
The result
1,573 sq ft, cleared, sealed and re-insulated
The attic went from an active rodent problem to a code-level space in a single visit – cleared, sanitized, closed against re-entry, and rebuilt in R-38 16in Fiberglass Batts.

Questions homeowners ask
Attic work in Lawndale, answered
Does old attic insulation have to be removed, or can new insulation go on top?
It depends what the inspection finds. Where the existing layer is clean and intact, Atticare USA can add over it. On this Lawndale project the crew found severe rodent activity in the insulation itself, so the whole layer came out and the space was sanitized before new insulation went in — why the order of operations decides whether it holds. More on the choice: cleaning versus full replacement.
What does rodent proofing include in Lawndale?
Rodent proofing is exclusion work: sealing the gaps and openings rodents use to get in, with wire mesh, polyurethane foam and cement, then setting two to four indicator traps to confirm the space stays clear. Live removal, where it is needed, is handled by a licensed pest control provider. Atticare USA has written up the entry points rodents actually use and the 5-step restoration process that follows. Worth reading before you compare quotes: how to compare rodent-proofing warranties.
