How to Assess Vehicle Glass Damage Yourself

How to Assess Vehicle Glass Damage Yourself

You can work out most of what matters about glass damage in about two minutes, and it makes the conversation with a repairer far more useful. Four things determine what happens next: how big it is, what type it is, where it sits, and whether it is moving. Here is how to check each one.

The Four Checks

Work through these in order:

• Size — compare against a coin. Under a five-cent piece is usually repairable territory; a crack longer than your hand span generally is not.
• Type — a bullseye (circular), star (radiating lines), combination, or a straight crack. Chips repair better than cracks.
• Location — is it in the driver line of sight, or within about 5cm of the edge? Both push toward replacement.
• Movement — mark the end of a crack with a pen and check in a day. If it has grown, act now rather than later.

What Each Result Means

Small, central-but-not-in-the-driver-view, non-moving damage is a straightforward stone chip and crack repair from $110. Damage in the driver’s direct line of sight is usually a replacement even if technically repairable, because a repair leaves a faint mark where it matters most. Edge damage is a replacement because the perimeter is the structural bond zone. A crack that is actively spreading is urgent — temperature swings and rough roads accelerate it quickly.

What It Costs

Our starting prices are the same across greater Sydney, with no call-out fee:

Service	Starting From
Stone Chip and Crack Repairs	$110
Windscreen Replacement	$330
Body Glass Replacement	$165
Resealing	$165
Scratch Removal	$110
Window Tinting	$250

The final figure depends on your vehicle, the glass specification and whether calibration is needed. We confirm it before starting. See what windscreen replacement costs in Sydney for a fuller breakdown.

When It Is Not Safe to Drive

Some damage means stopping rather than booking. A crack across the driver’s primary view, damage that has penetrated both layers of the laminate, glass that flexes or feels loose, or a shattered side window all warrant getting off the road. NSW roadworthiness rules treat significant windscreen damage in the driver’s view as a defect. If you are unsure, send us a photo — assessment costs nothing. Our repair versus replacement guide covers the decision in more depth.

Frequently Asked Questions

How do I measure the damage?

A coin is the easiest reference. Chips smaller than a five-cent piece are generally repairable; anything larger, or a crack longer than your hand span, usually is not.

Why does edge damage matter so much?

The perimeter is where the glass bonds to the body and carries structural load. Damage there compromises that bond and cannot be reliably repaired.

How do I know if a crack is spreading?

Mark the tip with a marker pen and check again after a day of driving. Growth beyond the mark means it is active.

Can I just send a photo?

Yes — a clear photo with something for scale next to the damage lets us tell you whether it is repairable before booking anything.
