Vendor Selection

Red Flags in Exterior Services Proposals

Part of the guide Vendor Selection, Compliance, and Procurement

The short answer

Be wary of proposals with vague scope, a price far below the others, no insurance or safety detail, silence on who does the work, a single total with no breakdown, or contract terms that lock in increases.

Scope red flags

  • "All windows" with no quantities, sides or elevations
  • No access method named for buildings over a few stories
  • Add-ons and first-time cleans left unpriced

See what a scope of work must specify.

Price red flags

  • A total far below the others with no explanation
  • No per-visit or per-building breakdown
  • Mobilization or surcharges hidden in the terms

See how to compare exterior services bids.

Risk red flags

  • No certificate of insurance offered, or a slow one
  • No mention of a safety plan for at-height work
  • No question about your roof anchors
  • Vague answers on who does the work
  • No references on comparable buildings

Contract red flags

  • Uncapped or unindexed escalators
  • Auto-renewal with a short notice window
  • No termination for convenience
  • No change-order process

See escalators, fuel surcharges and contract terms.
