A small chip in your windscreen might not seem like a big deal, but it has the potential to turn into a larger, more costly crack if left unattended. Understanding what causes chips to crack and how to identify high-risk damage can save you both time and money. In this article, we’ll explain the factors that affect windscreen chips, how to recognise those that are likely to worsen, and what you can do to prevent further damage.
Factors That Cause Windscreen Chips To Turn Into Cracks
Not all chips will turn into cracks, but certain conditions increase the likelihood. Recognising these factors can help you take action before the damage worsens.
Temperature Changes
Extreme or sudden changes in temperature are one of the main causes of chips turning into cracks. For example, pouring hot water on an icy windscreen or using the car heater at full blast on a frosty morning can cause the glass to expand unevenly. Similarly, parking in direct sunlight after a cold night can create stress on the damaged area.
Driving Vibrations
Everyday driving can put stress on your windscreen, especially if you frequently drive on rough roads, potholes, or uneven terrain. The constant vibrations and jolts can weaken the glass around the chip, leading to cracking over time.
Impact From Flying Debris
If a chip is already present, even a small impact from gravel, stones, or other debris can make the damage worse. Driving at high speeds on motorways or behind construction vehicles increases the risk of debris hitting the windscreen.
Pressure On The Glass
Chips are more likely to spread if pressure is applied to the windscreen. This can happen when cleaning the glass with too much force, leaning on it, or even slamming car doors, which creates a sudden burst of air pressure inside the vehicle.
How To Identify High-Risk Windscreen Chips
Not all chips are the same, and some are more likely to develop into cracks. Knowing what to look for can help you determine when to take action.
Chips Near The Edge Of The Windscreen
Chips located near the edges of the windscreen are more likely to spread into cracks. This is because the edges of the glass are under more tension, and any damage in these areas weakens the overall structure.
Larger Or Deeper Chips
The size and depth of a chip play a significant role in whether it will turn into a crack. Small, shallow chips are generally less risky, while larger or deeper ones are more prone to spreading. Chips larger than a £2 coin should be addressed immediately, as they are less likely to remain stable.
Chips In The Driver’s Line Of Sight
Even if a chip doesn’t seem large, its location matters. Chips in the driver’s direct line of sight are more likely to require urgent attention because cracks in this area can obstruct visibility and pose a safety risk.
Steps To Prevent A Windscreen Chip From Becoming A Crack
Taking quick and simple steps can help reduce the chances of a chip turning into a crack. Here are some practical tips for keeping your windscreen damage under control.
Drive Carefully On Rough Roads
If you have a chip, try to avoid driving on rough or bumpy roads. Slow down when approaching potholes or uneven terrain to minimise vibrations and reduce stress on the glass.
Avoid Sudden Temperature Changes
Instead of pouring hot water on a frosty windscreen, use the car’s defrost setting gradually to warm the glass. During hot weather, park in shaded areas to prevent excessive heating. Avoiding sudden temperature changes helps the glass maintain its strength around the chip.
Use Clear Tape As A Temporary Fix
Covering a chip with clear tape can help protect it from dirt, moisture, and further stress. This is not a long-term solution, but it can buy you time while you arrange for professional repairs.
Seek Professional Repairs Quickly
The most reliable way to prevent a chip from turning into a crack is to have it repaired by a professional. Repairs are often quick and affordable, especially if addressed early. Many chips can be fixed using a special resin that restores the strength of the glass and prevents the damage from spreading.
