Completed project · San Rafael, CA 94901 · September 2026
Heavy rodent waste had worked into the old white loose-fill in this San Rafael attic, and the job record rates the activity as severe. Atticare USA removed every bit of it across 775 sq ft, sanitized the deck, meshed the vents and openings, and installed new R-38 16in fiberglass batts.

The challenge
Severe rodent activity and open vents
The old loose-fill held heavy rodent waste, droppings and nests. Material in that state carries odor and the scent trail that draws the next animal in, so all of it had to come out.
The photos also show where the problem could return: vents and openings in the attic, and gaps around pipes. Each was closed with wire mesh and foam before the new insulation 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 775 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.
New insulation
New R-38 16in Fiberglass Batts installed across 775 sq ft, on a clean, sealed surface rather than on top of the old layer.
The result
775 sq ft, from contaminated loose-fill to R-38 batts
Floor barriers were laid through the work path, the old insulation came out with a heavy-duty vacuum, the heavy rodent waste, droppings and nests were vacuumed out, and OdoBan was applied. The attic was then rodent-proofed with wire mesh, polyurethane foam and cement, gaps around fixtures, piping, wiring and vents were air-sealed, and new R-38 16in batts went in last, with two to four indicator traps left as a check.

Questions homeowners ask
Attic work in San Rafael, answered
Who seals rodent entry points and rodent-proofs the attic in San Rafael?
Atticare USA does. On this San Rafael job the crew screened vents with wire mesh, fitted mesh and foam around pipes and over holes, and sealed gaps with polyurethane foam and cement. Two to four indicator traps were left as a check. Where live animals need removing, a licensed pest control provider handles that part. The rodent proofing carries a 1-year warranty. See rodent exclusion in the South Bay and North Bay.
Who does attic decontamination and reinsulation after a rat problem in San Rafael?
Atticare USA does both in one project. Here the old loose-fill had heavy rodent waste through it, so it all came out, droppings and nests were vacuumed out, OdoBan was applied to neutralize odors, pheromones and bacteria, the attic was sealed, and new R-38 batts went in last.
