Sometimes. If hoarding led to covered damage such as water, mold, or pests, a homeowner's policy may help, though the cleanup itself often is not covered. Ask the company, since many help document the job for a claim.
Reputable Ontario crews are trained and insured for biohazards like mold, waste, and sharps, and will sanitize the home after removal. Always confirm this before hiring.
Beyond hauling, good hoarding crews work compassionately, sort and protect valuables and documents, and can coordinate with family or care providers. It is about the person, not just the property.
