Attic Insulation Replacement & Rodent Proofing in Santa Rosa, CA

Completed project · Santa Rosa, CA 95409 · July 2026

Severe rodent activity ran through 1,829 sq ft of Santa Rosa attic, in a layer of old yellow batts left loose and torn across the floor. Atticare USA stripped it to a clean deck, sanitized and sealed it, and rebuilt it with R-38 24in fiberglass batts plus R-19 16in.

The challenge

Torn old batts and a severe rodent record

The before photos show the old yellow batts loose and broken up across the attic floor. The job record marks rodent activity as severe, with heavy rodent waste, droppings and nests through the material.

At that level none of the old layer could stay. The order was fixed: protect the work path, remove everything, clean and sanitize the deck, seal the openings, and only then lay the new insulation.

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 1,829 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 24in Fiberglass Batts and R-19 16in installed across 1,829 sq ft, on a clean, sealed surface rather than on top of the old layer.

The result

1,829 sq ft, from a clean deck to R-38

Protective barriers went down through the work path first. The old insulation came out with a heavy-duty vacuum, heavy rodent waste, droppings and nests were vacuumed out, OdoBan was applied, entry points were sealed with wire mesh, polyurethane foam and cement, gaps around fixtures, piping, wiring and vents were air-sealed, and new R-38 24in and R-19 16in fiberglass batts went in last. Two to four indicator traps were left as a check.
