Recent Crawl Space Work in Duvall
Crawl Space Cleaning & Rodent Cleanup Highlight
Attic Doctor completed a residential crawl space project in Duvall on March 10, 2026, involving crawl space cleaning after rat activity was found in the home. The original plan included a new vapor barrier, but after cleanup and prep, the team determined the next step would require spray foam instead. The project followed a normal workflow overall, with extra rodent proofing needed because the home was a mobile home structure.

Next Step Identified
Spray foam needed after cleanup
Scope
- Crawl space cleaning
- Removal of insulation and loose debris
- Prep for new vapor barrier
- Extra rodent proofing for a mobile home
- Assessment of conditions after cleanout
Outcome
- Crawl space was cleaned out successfully
- Existing insulation and debris were removed
- One dripping water pipe was noted for the homeowner to address
- Vapor barrier installation was deferred in favor of spray foam
- Customer was happy with the cleaned crawl space and excited for the next step
Key Takeaway
Even routine crawl space cleanout jobs can shift once the area is fully opened up and assessed. In this Duvall project, Attic Doctor completed the cleaning, prepared the space, and identified that spray foam—not a vapor barrier—was the better next step, while also accounting for the added rodent proofing needs of a mobile home.
