Attic Insulation Replacement, Rodent Proofing & Air Duct Work in Fairfield, CA

Completed project · Fairfield, CA 94533 · January 2026

Two kinds of new insulation went into this Fairfield attic: R-38 24in fiberglass batts across the floor, and R-19 16in batts in the walls. Before either, Atticare USA removed the old layer, cleaned and sanitized the attic, sealed openings with wire mesh and foam, and replaced the air ducts to code at the existing diameters.

The challenge

An old layer on the floor, and open framing around the edges

The inspection photos show old loose-fill across the attic floor, with debris mixed through it and the ducts lying on top.

The attic also had walls to insulate, not just a floor. So the job covered both surfaces, and the sealing had to reach the openings in the framing and around the pipes before any of the new batts 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, 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.

Air duct replacement

Air ducts removed and replaced to code, matching the existing diameters.

New insulation

New R-38 24in Fiberglass Batts in the attic and R-19 16in in the walls installed, on a clean, sealed surface rather than on top of the old layer.

The result

Floor and walls rebuilt, with new ducts

Protective floor barriers went down through the work path first. All existing insulation came out with a heavy-duty vacuum, 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. New R-38 24in fiberglass batts went in on the floor and R-19 16in batts in the walls, last.
