Auto glass guides
Clear answers to the questions we hear most: what a windshield costs in California, whether insurance pays, when a chip can be repaired, how long to wait before driving, and what changes under the 2027 glass law.
- After Windshield Replacement CareFor the first 24 hours, wait out the safe drive-away time, leave the retention tape on, skip the car wash, crack a window about an inch and close doors gently. Wait 48 to 72 hours before high-pressure washing near the edges or mounting anything to the glass. Call the installer about leaks, wind noise or camera warnings.
- California Motor Vehicle Glass Act (SB 988)SB 988, the California Motor Vehicle Glass Act, takes effect January 1, 2027. It requires glass shops to tell you before work whether your car has ADAS and needs calibration, give written calibration results, estimates and itemized invoices, and wait for a claim number. It bans claim rebates and assignment of benefits. Penalties reach $2,000 per repeat violation.
- Cracked Windshield Law in CaliforniaIt depends on whether the damage impairs your view. California Vehicle Code 26710 makes it unlawful to drive with a windshield or rear window so damaged that it impairs the driver's vision to the front or rear. An officer can order repair within 48 hours and issue a notice to appear. A small chip outside your view usually doesn't qualify.
- Insurance and Windshield ReplacementYes, if you carry comprehensive coverage. A cracked windshield is usually a comprehensive claim, so you pay your comprehensive deductible and the insurer pays the rest. California has no law waiving that deductible. Many insurers waive it for chip repair, and California Insurance Code 758.5 lets you choose your own glass shop.
- OEM vs. Aftermarket WindshieldsOEM windshields carry the automaker's brand. OEE (original equipment equivalent) and aftermarket windshields are made by other glass companies to fit the same car. All windshields sold in the U.S. must meet federal standard FMVSS 205 and be marked AS1. OEE usually costs less; OEM can matter for some heads-up displays and cameras.
- Repair or Replace a WindshieldRepair it if the chip is smaller than a quarter (about 1 inch) or a single crack is under about 6 inches, it isn't in the driver's direct line of sight, and it doesn't touch the edge of the glass. Replace it if the damage is larger, at the edge, in front of the driver, or over the camera area.
- Safe Drive-Away TimeYou can drive once the safe drive-away time has passed: the point when the urethane adhesive is strong enough to hold the windshield in a crash. According to I-CAR, fast-cure urethanes reach it in about 30 to 60 minutes and conventional ones in 2 to 8 hours or more. Some automakers require 24 hours.
- Static vs. Dynamic ADAS CalibrationStatic calibration aims the windshield camera while the car is parked in a level, well-lit space in front of printed targets set at exact distances. Dynamic calibration aims it while a technician drives at set speeds on clearly marked roads with a scan tool connected. The automaker decides which your car needs. Some cars need both.
- Why Rock Chips Spread in HeatRock chips spread in heat because glass expands and contracts with temperature, and a chip concentrates that stress at one weak point. Sudden changes are the worst: cold A/C or a car wash on sun-baked glass, or a hot day followed by a cool night. In the Temecula Valley, summer highs often pass 100°F, so chips can crack quickly.
- Windshield Replacement CostIn 2026, industry guides put a standard California windshield replacement at about $250 to $600. Cars with a forward camera usually cost $800 to $1,500 or more once calibration is included, and AAA found the average windshield job with calibration was about $1,440. Our replacements start at $279, or $549 with calibration.
- Windshield Replacement in RainNot out in the open. Water on the glass or the car's frame can keep the urethane from bonding, so mobile installers don't replace windshields in active rain. Under a garage or carport it can usually go ahead. Strong wind and cold, dry air also slow curing and can lengthen the safe drive-away time or force a reschedule.
- Zero-Deductible Glass Coverage in CaliforniaNo. California has no law requiring insurers to replace windshields without a deductible. Glass claims normally fall under comprehensive coverage, so you pay your comprehensive deductible. Some insurers sell optional full glass coverage that lowers or removes it. Florida and Kentucky have statutes that waive the deductible on glass claims; California does not.
