Start this checklist

Right after it happens (4)

  • Do not slam doors or drive on bumpy roads until it is dealt with
  • Do not blast the heater or de-icer at full: sudden heat spreads a crack
  • Cover the chip with clear tape to keep dirt and water outA repair works best when the chip is clean and dry.
  • Note where it is, how big, and take a photo

Size and place decide (4)

  • Chip smaller than a 2 cm coin: usually repairable
  • Crack longer than about 30 cm (a banknote): usually needs a new windscreen
  • Damage right in the driver’s line of sight: replace, a repair can leave a blur
  • Damage near the edge of the glass: replace, edges weaken the whole screen

Call and ask (4)

  • Check your insurance: many policies cover a repair with no excess
  • Ask the repair company if they come to you and how long the glue needs to cure
  • Ask whether the camera or rain sensor needs to be recalibrated after a new screen
  • Get the price in writing before you agree

After the repair (4)

  • Keep the car dry for the time they tell you, often an hour
  • Leave the windows slightly open for the first day
  • Do not use a car wash for 24 to 48 hours
  • Keep the receipt for insurance
