Owners usually carry the cost of cleaning their own property. For rentals, the lease and local law decide who is responsible, and a landlord, an attorney or a tenant rights group can say. Renters policies often cover a tenant's belongings rather than the building.

Because residue is usually invisible. Testing shows which rooms and materials are affected, guides the cleanup plan and later shows whether the work succeeded. Reports from before and after the job are what buyers, lenders, insurers and local officials often ask to see.
