Questions we get asked a lot

Usually, if the chip is smaller than a 20-cent coin, isn't directly in the driver's line of sight, and hasn't started to crack. We assess it before starting any work and tell you if it can't be repaired.

A crack that reaches the edge of the glass, or one in the driver's line of sight, means replacement. Cracks keep spreading with temperature changes and vibration, so a short one today can be a long one next week. Send us a photo or bring it in and we'll tell you.

No. Side and rear glass is tempered and breaks into small pieces, so it's replaced. We do door, quarter and tailgate glass, and we clear the door cavity properly rather than leaving loose glass in it.

If the vehicle has a camera on or near the windscreen for lane keep assist, automatic emergency braking or adaptive cruise, yes. We check every vehicle before the job and book the calibration with National ADAS Calibrations in the same visit when it's needed.

The camera looks through the windscreen, and it's mounted to it. A new piece of glass sits a fraction differently, and a tiny angle error at the camera becomes a large error down the road. Calibration tells the system exactly where it is looking again.

Static calibration uses targets set up at measured distances in the workshop. Dynamic calibration is done by driving on a road with clear lane markings while a scan tool guides the process. Some vehicles need one, some need both, and the manufacturer decides which.

We accept insurance and fleet billing arrangements. Bring your claim number and we'll sort the invoicing on our side. The calibration report, where there is one, goes in the claim file.

Use the form on the home page or call us. Give the make, model and year (or the rego), say where the damage is, and tell us if there's a camera behind the mirror. The final price is confirmed once the vehicle is inspected, because glass type and trim level vary between cars that look the same.

The glass itself is usually a 60 to 90 minute job. If calibration is needed too, plan for the vehicle to be with us for most of the day, since the urethane has to cure before the car is safe to drive and before the targets can be set up.

It depends on the urethane, the temperature and the vehicle. We tell you the safe drive-away time for your car when it's finished. It's often around an hour in mild weather, and longer in the cold.

Give it at least a day before an automatic wash or a pressure hose, and leave any retention tape on the glass for as long as we tell you. A hand wash is fine sooner. Follow the instructions we give you for your vehicle, since they depend on the urethane we used.

Tell us straight away. It's uncommon, but a wind noise or a damp patch after a fit should be looked at, not put up with. Call the workshop and we'll book you in to check it.
