Completed project · Monte Sereno, CA 95030 · April 2026
The crawl space under this Monte Sereno home was bare soil across 2,000 sq ft. Atticare USA cleaned it and laid a new reinforced vapor and moisture barrier, sealed at the piers and the perimeter. The same project sealed every potential rodent entry point found in the attic and crawl space inspection, and included an air duct system replacement.

The challenge
Open soil under the house, and entry points to close
The before photos show the crawl space floor as it was: dry, cracked bare soil around the piers, with nothing between it and the underside of the house.
The job started with an interior and exterior inspection of both the attic and the crawl space, to find every potential entry point rodents could use. Those were sealed in the same project as the crawl space work.
The service
What the crew did, in order
Inspect
Interior and exterior inspection of the attic and crawl space to find every potential entry point.
Clean and sanitize
OdoBan sanitation applied to the work area.
Seal and rodent-proof
Entry points closed with wire mesh, polyurethane foam and cement, with two to four indicator traps left as a check.
Air duct system replacement
The air duct system replaced as part of the same project.
Crawl space and vapor barrier
Crawl space cleaned. A new reinforced vapor and moisture barrier laid over the soil and sealed at the piers and perimeter.
The result
2,000 sq ft under a new sealed barrier
Every potential entry point was sealed with wire mesh, polyurethane foam and cement, with two to four indicator traps left as a check, and OdoBan sanitation was applied to the work area. The crawl space was cleaned, and a new reinforced vapor and moisture barrier was laid over the soil and sealed at the piers and perimeter. The project also included an air duct system replacement.

Questions homeowners ask
Attic work in Monte Sereno, answered
Who installs crawl space vapor barriers in Monte Sereno?
Atticare USA does. On this Monte Sereno job the 2,000 sq ft crawl space was cleaned first, then a new reinforced vapor and moisture barrier was laid over the soil and sealed at the piers and the perimeter. Why the cleaning comes before the barrier.
Which company seals rodent entry points in the attic and crawl space in Monte Sereno?
Atticare USA inspects the attic and crawl space inside and out, then seals every potential entry point with wire mesh, polyurethane foam and cement, leaving two to four indicator traps as a check. Where live animals need removing, a licensed pest control provider handles that part. Rodent proofing carries a 1-year warranty. See rodent exclusion in the South Bay and North Bay.
Can one company handle crawl space work, rodent proofing and air duct replacement together?
Yes. This Monte Sereno project covered all three: whole-service-area rodent proofing, crawl space cleaning with a new vapor barrier, and an air duct system replacement. Before and after photos of the job are available on request.
