It’s normal to get the odd chip or crack in your windscreen, but if you’re not careful, a tiny crack could escalate and become a much larger, more concerning problem. As soon as you see a chip in your car’s windscreen, you should have it looked into ASAP to prevent further damage, safety concerns, or a larger cost for a full windscreen replacement.
How To Know If Your Windscreen Can Be Repaired?
Depending on the extent of the damage, you might be able to get away with a simple repair job. This involves a company injecting epoxy or acrylic into the crack which expands and adheres to the glass, preventing the spread of more cracks in your windscreen.
To decide whether a simple repair job will be adequate, you’ll need to consider the size of the damage, the location on the windscreen, and whether the damage has spread.
Location of The Damage
Windscreen repairs are dependent on where the damage is. Your windscreen is broken up into 4 zones:
– Zone A is directly in front of the driver. It’s the space you see when you’re looking straight ahead at the road.
– Zone B is either side of zone A – the peripheral vision of the driver.
– Zone C is directly in front of the passenger – the space that they see when looking straight ahead.
– Zone D is the area around the outside of the windscreen.
The closer to zone A that your damage is, the more chance that you’ll need to get a full windscreen replacement as any spread of a crack might obscure the driver’s vision.
Zone D can usually be repaired unless the damage is particularly severe, as it doesn’t pose an obstruction to the driver.
Size of The Damage
The size of the damage goes hand-in-hand with the location. If the damage measures less than 10 mm, it can usually be repaired no matter where it is on the windscreen. However, anything larger than that in zone A will require a full windscreen replacement. This is because, although repairs are almost invisible, there’s no guarantee that cracks won’t open back up and if the damage is right in front of the driver, it could pose a risk.
15 mm damage can be repaired if in zone B, 25 mm in zone C, and up to 40 mm in zone D. Any damage that measures more than 40 mm in any direction cannot be repaired and it’s time to replace the windscreen.
Cracks can spread rapidly if they aren’t dealt with, and a tiny chip one day could crack across the whole windscreen within a few days if you’re not careful.
The type of crack could determine whether it’s a quick repair job or a whole new windscreen. If the crack is just on the surface of the glass, then you may be able to get away with a repair. However, if the crack goes all the way through the glass, this can’t be repaired, and you will need a full windscreen replacement.
Equally, the speed of a crack’s progression will determine if it can be repaired. If you’ve had the crack for a few days and it seems to have remained static, there’s more chance of a repair as the glass has remained stable despite the damage. However, if you notice a quick spread and the crack is getting larger by the day, unfortunately, the glass structure has been affected and an attempt at windscreen repair may not work.
