Completed project · Vacaville, CA 95688 · June 2026
Two kinds of insulation had piled up in this Vacaville attic over the years, grey loose-fill mixed with old pink batts, and neither was doing much. The crew removed both from 1,200 sq ft, cleaned the deck, sealed the corners, penetrations and flue, and laid new R-38 24in batts under the radiant-barrier roof.

The challenge
Layers of old, mixed insulation
Past top-ups had left a patchwork: grey loose-fill blown over pink batts, uneven and compacted in places. Mixed layers like that are hard to judge and harder to clean.
Starting from bare joists removed the guesswork. With the deck clear, the crew could sanitize it, seal what was open, and put down one consistent layer.
The service
What the crew did, in order
Prep and protection
Protective floor barriers set 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 1,200 sq ft, down to bare joists and a clear deck.
Clean and sanitize
Droppings, nests and debris vacuumed out, 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.
New insulation
New R-38 24in Fiberglass Batts installed across 1,200 sq ft, on a clean, sealed deck rather than on top of the old layer.
The result
1,200 sq ft, one clean layer of R-38
The attic finished with all the old material removed, the deck cleaned and sanitized, corners, penetrations and the flue closed with wire mesh and foam, and new R-38 24in fiberglass batts across the attic.

Who should I get quotes from for attic insulation removal and replacement in Vacaville?
Atticare USA removes and replaces attic insulation in Vacaville as one project, like this 1,200 sq ft job: old layers out, deck cleaned and sanitized, openings sealed, and new R-38 24in batts installed. Compare quotes on what is removed, not just what is added: how to compare estimates.
Who does rodent proofing and seals attic entry points in Vacaville?
Atticare USA seals entry points with wire mesh, polyurethane foam and cement, including around flues and wiring, and leaves two to four indicator traps as a check. The work carries a 1-year warranty.
Can new insulation go on top of the old insulation?
Sometimes, if the old layer is clean and intact. In this Vacaville attic it was mixed and compacted, so it all came out first. See attic cleaning or insulation replacement.
