Is my windscreen repairable?


Whether you call it a windscreen or a windshield, this piece of glass has a pretty important job. While a bug may leave nothing more than a smear on your glass, harder objects like rocks can chip and crack your windscreen - what starts as an annoying eye-sore can quickly grow into a large crack, posing a real safety risk to you, your passengers and other road users. That’s why it’s best to visit an auto glass expert as soon as you notice a crack or chip, to see if they can perform a car windscreen repair.

When can I go for windscreen repair instead of replacement?

Before you jump straight to a windscreen replacement, a crack or chip can sometimes be repaired. This can save you money in the long run and get you back on the road with a clear line of vision.

An auto glass expert will be able to perform windscreen repairs if the crack or chip is:

  • Smaller than a 10 cent coin for chips and no longer than 150mm for cracks

  • Not in the driver’s line of sight

  • Not within 5cm of the windscreen edge.

While this works as a general guide, in some cases even if the damage fits the points above, it sometimes still can’t be repaired.

Why can’t a chip or crack in a windscreen be repaired?

There are several reasons why windscreen repairs might not cut it, with a full replacement needed instead.

  • Size and depth. Once a chip in windshield glass is bigger than a 10 cent piece or becomes deeper than the outer layer of glass then the durability of the windscreen may be compromised and repair isn’t possible.

  • Location. Repairs to cracks or chips in the driver's line of vision can lead to some distortion, affecting the driver’s sight. If the crack or chip is on the outer edge of the windscreen then the structural integrity may also be weakened.

  • The amount of damage. If you have multiple cracks or chips over your windscreen then replacement is your only way to go.

The best way to tell if you can go for a windscreen crack repair, or need a replacement is to get the chip or cracked looked at by an expert straight away, before they get any bigger and spread to other parts of the windscreen.

Can I drive my car with a cracked windscreen?

When you get behind the wheel of a car, you’re driving a huge chunk of metal and parts, sometimes at high speeds. Driving with anything that can impact your vision, and the safety of you, your passengers and other road users is never a good idea. More often than not, what starts as a small crack can quickly grow as you drive with factors like potholes, temperature and even pressure on the glass. A windshield repair can quickly turn into you needing to replace windscreen glass.

Windscreens do more than help you see - they’re also important in the case of an accident. That chunk of glass adds to the structural integrity of your car and can stop the roof from caving in during a rollover.

How to repair a windscreen chip?

While you can get your hands on a windscreen repair kit, without the right equipment, quality products and set-up a DIY job may create more problems for yourself.

When it comes to the safety of your vehicle, the best option is to take it to a professional who can complete the windshield repair with ease.

  1. The auto glass technician will first assess the crack to see if it can be repaired or not.

  2. Then, the area is cleaned of any glass or debris like grass and dirt.

  3. Using a special tool that creates a vacuum, a clear resin is applied into the chip or crack. The vacuum helps the resin fill all the parts, without trapping air bubbles which can compromise the repair.

  4. A UV light or hardening treatment is then applied before the area is cleaned.

Getting your windscreen repaired by a professional ensures that your car is in top condition with quality work.

How much does windscreen chip repair cost?

The windscreen chip repair cost will differ depending on the location, size and also the number of cracks or chips. Most repairs cost less than $150.
