The fall windshield calendar that every driver should know: EARLY SEPTEMBER brings peak acorn and seed drop season across most of the US, with tree-lined parking lots creating overhead impact risks not present in summer. MID-SEPTEMBER brings first use of rear defrosters on cool mornings, and any existing crack that survived summer becomes a thermal stress risk when heated glass meets cool morning air. LATE SEPTEMBER brings the first real frost warnings in northern markets, and drivers who blast defrosters to clear frost create rapid temperature differential on glass that propagates existing chip damage into spreading cracks overnight. Our fall auto glass guide covers each risk in detail with the specific conditions that trigger damage and the repair window that closes as each risk compounds previous damage. Windshield replacement in 2026 costs $275 to $1,100 plus $150 to $500 for ADAS calibration on equipped vehicles. Repairing a summer chip before fall damage compounds it costs $80 to $160 or zero with comprehensive insurance. The math strongly favors early September action.
