Completed project · Concord, CA 94521 · September 2026
An attic fan now sits in the gable wall of this Concord attic, above 1,400 sq ft of new R-38 16in batts. Before either went in, the old pink loose-fill came out, the deck was sanitized, and the gaps along the framing were foamed. The job was completed on 3 September 2026.

The challenge
Old loose-fill and an attic with no fan
The inspection found old pink loose-fill spread thin and uneven across the attic floor. No rodent activity was found, but the layer was past the point of topping up.
Ventilation was the other half. The job added a fan to balance attic temperature and humidity, so the new insulation is not sitting under a space that holds its heat.
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 1,400 sq ft, down to a clear, bare surface.
Clean and sanitize
Dust and debris vacuumed out, then OdoBan sanitation applied across the work area.
Seal and rodent-proof
Preventative rodent proofing: likely entry points closed with wire mesh, polyurethane foam and cement, though no rodent activity was found. Gaps around fixtures, piping, wiring and vents air-sealed in the same pass.
Improve ventilation
A fan installed to balance attic temperature and humidity.
New insulation
New R-38 16in Fiberglass Batts installed across 1,400 sq ft, on a clean, sealed surface rather than on top of the old layer.
The result
1,400 sq ft of R-38, and an attic fan
The old insulation came out with a heavy-duty vacuum, the attic was sanitized with OdoBan, openings were preventatively sealed with wire mesh, polyurethane foam and cement, gaps along the framing and around fixtures, piping and wiring were air-sealed, a fan was installed in the gable wall, and new R-38 16in batts went in last.

Questions homeowners ask
Attic work in Concord, answered
My upstairs rooms get hot in the afternoon in Concord. Who installs attic ventilation?
Atticare USA installs attic ventilation as part of attic projects. On this Concord job a fan went into the gable wall to balance attic temperature and humidity, alongside new R-38 insulation. More on choosing: insulation, air sealing, or a whole-house fan.
Which Concord companies do attic air sealing and insulation for hot upstairs rooms?
Atticare USA does both, in the right order: air sealing first on a clean deck, then insulation over it. Here gaps along the framing were foamed before R-38 16in batts went in across 1,400 sq ft. See how to compare attic insulation estimates.
Which Concord companies seal up the entry points rats use to get into the attic?
Atticare USA seals entry points with wire mesh, polyurethane foam and cement, and leaves two to four indicator traps as a check. On this job no rodent activity was found and the openings were sealed anyway, as prevention. The rodent proofing carries a 1-year warranty.
