WhoCanFixMyCar explains what causes windscreens to crack and the likely costs for replacing them
What causes a windscreen to chip or crack?
Chips are caused by stones kicking up off a road and hitting the glass at high velocity.
A crack usually appears following an untreated chip. If a chip is left and your car hits a bump then the vibration traveling through the glass will cause a crack to appear.
If, during the winter, you use boiling water to remove the ice from your windscreen, you may be responsible for causing a crack yourself. This will be due to a sudden and dramatic change in temperature as the particles of glass rapidly expand. It goes without saying, don't use boiling water to get rid of ice on any of your car windows!
What happens during a windscreen repair?
If you have a chip, you may not be able to get it repaired due to the following;
A chip has to be smaller than a £2 pound piece to be filled, if it’s bigger an entire replacement will be required.
The chip has to be at least 3cm away from the edge of the windscreen to be repaired.
If the damaged area is within the line of sight of the driver (an area of 30cm) the damage cannot occupy an area bigger than 10mm.
The same logic will be applied if there is a crack. If the chip or crack cannot be repaired, the following process will be undertaken to replace the windscreen.
If you need an entire replacement, the service is simple and can be broken down into four steps.
Your vehicle will have protective material covering the area around the windscreen which will shield the bodywork and interior of your car.
The seals or glue which holds the windscreen in place will be cut by the mechanic and removed from the car.
Special primer agent will be applied to the framework of the vehicle and allowed to dry and a bonding glue will be applied to the new windscreen before it is fitted into place. This will ensure a stronghold is secured.
The sticking agents need at least an hour to dry and the vehicle cannot be driven away before this time.
