The main cost factors

  • Affected square footage and number of rooms
  • Porous versus nonporous materials
  • Subfloor, wall cavity, HVAC, or vehicle-component involvement
  • Amount and type of material requiring containment or disposal
  • Access, parking, stairs, utilities, and occupancy constraints
  • After-hours availability and geographic travel
  • Required documentation, testing, or third-party clearance

What a written estimate should identify

  • Areas and tasks included
  • Materials proposed for removal
  • Cleaning, deodorization, disposal, storage, and repair exclusions
  • Labor or equipment assumptions
  • How change orders are approved
  • Deposit, payment, cancellation, and completion terms

How to compare contractors

  • Compare the scope - not only the total
  • Ask who performs the work and what insurance applies
  • Request the waste and disposal plan where relevant
  • Do not accept pressure to authorize work you do not understand
  • Keep photos, estimates, invoices, and completion records
