Do not disturb an unidentified substance
If a material, spill or residue may be hazardous, keep people away and contact the responsible site manager, emergency authority or qualified hazardous-material professional. Do not touch, sweep, vacuum, wash, transport or dispose of it based on a general article.

Request a written, itemised estimate
Ask the quote to separate assessment, mobilisation, access, containment, removal, transport, disposal, testing, reinstatement, taxes, contingencies and variations where applicable. Confirm what is excluded, what assumptions the price relies on, and whether the provider needs additional testing before a final scope.
Compare equivalent scopes, not headline prices
A lower quote may omit assessment, containment, transport, disposal or clearance documentation. Compare providers on the same identified material, site boundaries, work standard, records and completion conditions. Do not assume insurance covers the work or that a quoted cleanup makes a property safe.
Keep routine cleaning separate
Ordinary cleaning is not hazardous-material assessment, remediation, waste transport, testing or clearance. Dirt2Tidy makes no hazardous-cleanup service claim in this article; use a qualified provider authorised for the exact material and jurisdiction.
