The questions we hear most about crawl space work.

Most residential crawl spaces are workable with the right training, even at 18 to 24 inches of clearance.
It's not guaranteed against every scenario, but it resolves the underlying cause far more completely than surface treatment alone.
If previous work only treated visible growth without addressing vapor barrier gaps or drainage, the moisture source was never actually fixed.
Air moves between a crawl space and living areas more than most people expect, especially through gaps around plumbing and ductwork.
A standard treatment typically takes one day; full encapsulation can take two to three days depending on square footage.
