Commercial window film quote checklist and phased installation
Last revised October 26, 2026 · Published by Shore Tint & More, a 3M Authorized Window Film Dealer. Editorial disclosure
What the proposal should include
- Exact film product(s) and, for security work, the attachment system.
- Elevation-by-elevation glass survey with pane counts and glass types.
- Thermal stress/compatibility review for each glass type.
- Removal of existing film, if any.
- Access equipment (lifts, scaffolding) and site requirements.
- Schedule, working hours and occupant protection.
- Manufacturer and installer warranty terms in writing.
- Clear exclusions and assumptions.
Phasing that works
- Phase 1: the zones causing the most complaints (often west or south elevations).
- Later phases: remaining elevations, decorative work, or security upgrades.
- Keep the same product across phases for a consistent exterior appearance; confirm availability.
- Request a mock-up panel before phase 1 for sign-off.
Requesting a quote
