What moves the number
01
Per-opening economics
Cost scales with count — mobilization spreads over more units, so per-window price typically falls past ~8 openings.
02
Install type
Retrofit in existing frames is the reference; full-frame to the studs (×1.35) adds siding, trim, and flashing labor.
03
Frame tier
Vinyl is the floor, fiberglass ~×1.45, wood-clad premium ~×2.4 with full-frame install and high-end glass.
04
Rot at openings
Sill and framing rot found during install is the classic extra. The 10% contingency covers minor repair.
