Completed project · Petaluma, CA 94952 · July 2026
Two spaces, one project. In this Petaluma home the attic’s old yellow insulation and the crawl space’s torn, sagging duct runs both had to go. Atticare USA cleared 1,355 sq ft of attic and 1,075 sq ft of crawl space, replaced the air ducts, laid a vapor barrier and reinsulated both levels.

The challenge
Old insulation above, torn ducts and bare soil below
Up top, the before photos show old yellow and grey insulation packed around the pipes and framing, and the job record marks rodent activity as moderate, with droppings and nests in the material.
Under the floor, the old duct runs hung low with their outer wrap torn open, and the soil was bare. The scope covered both spaces to the same standard, so each one was cleared, cleaned and sealed before anything new 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
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 in the attic and R-19 16in faced in the crawl space installed, on a clean, sealed surface rather than on top of the old layer.
Crawl space and vapor barrier
Crawl space cleaned and insulated to the same standard as the attic. A new reinforced vapor and moisture barrier laid over the soil and sealed at the piers and perimeter.
The result
2,430 sq ft across attic and crawl space, rebuilt
Protective barriers went down through the work path first. The old insulation came out with a heavy-duty vacuum, rodent droppings and nests were vacuumed out, OdoBan was applied, openings were sealed with wire mesh, polyurethane foam and cement, and gaps around fixtures, piping, wiring and vents were air-sealed. Air ducts were removed and replaced to code, matching the existing diameters. A new reinforced vapor barrier was laid over the soil and sealed at the piers and perimeter, and new R-38 16in batts in the attic and R-19 16in faced batts in the crawl space went in last. Two to four indicator traps were left as a check.

Questions homeowners ask
Attic work in Petaluma, answered
Who should I call for crawl space cleaning, insulation, and a vapor barrier in Petaluma?
Atticare USA handles all three in one visit. On this Petaluma job the 1,075 sq ft crawl space was cleaned, a new reinforced vapor barrier was laid over the soil and sealed at the piers and perimeter, and R-19 16in faced batts went up under the floor. More on why the order matters.
Which company handles attic cleanup, rodent sealing, and insulation in one project in Petaluma?
Atticare USA. Here, with moderate rodent activity on the record, the attic was cleared with a heavy-duty vacuum, droppings and nests were vacuumed out, OdoBan was applied, openings were sealed with wire mesh, polyurethane foam and cement, and new R-38 batts went in last. Two to four indicator traps were left as a check, and the rodent proofing carries a 1-year warranty.
Who should I get quotes from for attic insulation and air sealing in Petaluma?
Ask for a quote that puts air sealing before insulation, as on this job: gaps around fixtures, piping, wiring and vents were sealed on the clean deck, then the new batts went over them. How to compare attic insulation estimates in the Bay Area covers what else to check.
