Businesses in the windscreens category repair and replace vehicle windscreen glass, including for cars, vans and other road vehicles. They assess damage such as stone chips and cracks to determine whether it can be repaired or whether the windscreen needs replacing. Repairs usually involve filling and curing suitable small areas of damage; replacement involves removing the damaged glass, preparing the frame and fitting a new windscreen with the appropriate bonding materials. Services may be provided at a workshop or at a customer's location, depending on the vehicle and the work required. Providers can also replace side and rear vehicle glass, check for leaks or wind noise after fitting, and advise on safe driving while bonding materials set. Where a vehicle has cameras or sensors mounted near the windscreen, replacement may require recalibration of driver assistance systems, such as lane departure warnings or automatic emergency braking.
