Completed project · Santa Rosa, CA 95405 · August 2026
Heavy rodent waste, droppings and nests ran through the old insulation in this 1,309 sq ft Santa Rosa attic. Atticare USA took the whole layer out, sanitized the deck, sealed the entry points and the gaps around fixtures, replaced the air ducts to code at the existing diameters, and finished with new R-38 fiberglass batts.

The challenge
Severe rodent activity, and ducts that needed replacing
The job record marks rodent activity here as severe. The old insulation held heavy rodent waste, droppings and nests, which meant none of it could stay in the attic under a new layer.
The air ducts ran through that same space, so the job covered them too. Doing the ducts while the attic floor was open, and before the new insulation went in, kept everything in one project and in the right order.
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 1,309 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 and R-38 24in Fiberglass Batts installed across 1,309 sq ft, on a clean, sealed surface rather than on top of the old layer.
The result
1,309 sq ft sanitized and sealed, with new ducts and R-38
Protective floor barriers went down through the work path first. Then 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 fiberglass batts in 16in and 24in widths went in last.

Questions homeowners ask
Attic work in Santa Rosa, answered
Who does rodent proofing and seals attic entry points in Santa Rosa?
Atticare USA does. On this Santa Rosa job the service area was sealed 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. Where live animals need removing first, a licensed pest control provider handles that part. Rodent proofing carries a 1-year warranty. See rodent exclusion in the South Bay and North Bay.
Who handles attic decontamination and reinsulation after rodents in Santa Rosa?
Atticare USA handles both in one project. In this attic, where the crew found severe rodent activity, the old insulation came out, droppings and nests were vacuumed out, OdoBan was applied, entry points were sealed, and new R-38 batts went in last on the clean deck. The 5-step process explains why the order matters.
Who does attic insulation removal and replacement in Santa Rosa?
