Completed project · Pasadena, CA 91103 · May 2026
No rodent activity was found in this 91103 attic, but the old loose-fill was uneven and full of debris. In May 2026 Atticare USA replaced it across 1,040 sq ft with R-38 batts and closed the likely way in before anything could use it.

The challenge
Uneven old loose-fill, and openings left unguarded
The inspection photos show the old loose-fill heaped in some places and thin in others, with broken wood and debris through it. Uneven cover like that leaves gaps where heat comes straight through the ceiling.
No rodent activity was recorded, but there were openings at the base of the house. Closing them during the same job protects the new insulation from the start.
The service
The 5-step solution, in order
Prep and protection
Floor protection and dust barriers set at the access point before any material was moved, so the rest of the house stayed clean.
Remove the old insulation
All the existing loose-fill taken out with a heavy-duty vacuum across 1,040 sq ft, down to bare joists and a clear deck.
Clean and sanitize
Dust and debris vacuumed from the deck, then OdoBan sanitation applied across the attic.
Seal and rodent-proof
No rodent activity was found, but the likely entry points were closed anyway 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 1,040 sq ft, on a clean, sealed deck rather than on top of the old layer.
The result
1,040 sq ft of Pasadena attic, reinsulated and closed
The attic finished with the old loose-fill removed, the deck cleaned and treated with OdoBan, entry points sealed with wire mesh, polyurethane foam and cement, air sealing around fixtures, piping, wiring and vents, and new R-38 16in fiberglass batts across all 1,040 sq ft.

Questions homeowners ask
Attic work in Pasadena, answered
Why is my attic insulation not keeping my Pasadena house cool?
Often because the old layer has settled or shifted, leaving thin spots, as the loose-fill in this 91103 attic had. Air leaks around fixtures and wiring also let hot attic air through. This job fixed both: the old loose-fill out, air sealing, and an even layer of R-38 batts. More: why insulation stops keeping a Pasadena home cool.
Is it worth rodent-proofing a Pasadena attic if there are no rats yet?
This homeowner did it as part of the insulation job. No rodent activity was found, but the openings were sealed with wire mesh, foam and cement while the crew was there, which protects the new insulation. The rodent proofing carries a 1-year warranty.
