Completed project · Alameda, CA 94501 · August 2026
Under this Alameda home, 1,000 sq ft of crawl space was stripped of its old insulation, cleaned and sanitized, then sealed off from the soil with a new reinforced vapor barrier, wrapped at the piers and perimeter. Pipe openings and foundation vents were closed with wire mesh and foam as part of rodent proofing across the whole service area.

The challenge
Old insulation under the floor, bare soil below it
The crawl space held old insulation that had to come out. The photos show bare soil across the floor, an unsealed opening around the plumbing, and foundation vents to close.
The job ran in order: remove the old insulation, vacuum debris from hard surfaces, sanitize the full work area with OdoBan, seal the entry points, and only then lay the barrier.
The service
What the crew did, in order
Remove the old insulation
The existing insulation taken out with a heavy-duty vacuum, down to a clear, bare surface.
Clean and sanitize
Debris vacuumed from hard surfaces, 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.
Crawl space and vapor barrier
Crawl space cleaned to the same standard. A new reinforced vapor and moisture barrier laid over the soil and sealed at the piers and perimeter.
The result
1,000 sq ft of crawl space, cleaned and sealed under a vapor barrier
The crawl space finished with the old insulation removed, debris vacuumed from hard surfaces, OdoBan applied across the work area, entry points sealed with wire mesh, polyurethane foam and cement, indicator traps left as a check, and a new reinforced vapor / moisture barrier laid over the soil and sealed at the piers and perimeter.
