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
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
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
