Windscreen damage can happen when you least expect it, whether it’s a small chip from a flying stone or a long crack that appears overnight. While both types of damage can be frustrating, the repair process for chips and cracks is quite different. In this article, we’ll explain the difference between chips and cracks, how each is repaired, and why it’s important to act quickly.
What Are Windscreen Chips And Cracks?
Not all windscreen damage is the same, and understanding the difference between chips and cracks can help you decide the best course of action.
Windscreen Chips
A chip is a small area of damage caused by an impact, such as a stone hitting the glass. Chips are usually circular or slightly star-shaped and can vary in size. Most chips are shallow and don’t go through the full thickness of the windscreen.
Windscreen Cracks
A crack is a longer line of damage that spreads across the windscreen. Cracks often start at the edge of the glass and grow over time due to vibrations, temperature changes, or pressure on the windscreen. Unlike chips, cracks weaken the structural integrity of the glass more significantly.
Common Causes Of Chips & Cracks
- Flying debris, such as stones or gravel, is the most common cause of chips. This usually happens while driving behind other vehicles, especially on motorways or rural roads.
- Cracks often develop from untreated chips or due to stress from extreme temperature changes, such as using hot water to defrost the windscreen on a cold day.
How Are Windscreen Chips Repaired?
Fixing a chip is usually straightforward, but the process depends on the size, depth, and location of the damage.
The Repair Process
Repairing a chip involves cleaning the damaged area and filling it with a special resin. This resin is then hardened using ultraviolet (UV) light, creating a clear, smooth finish. The repair strengthens the glass and prevents the chip from spreading into a crack.
When Can A Chip Be Repaired?
Most chips smaller than a £2 coin can be repaired, provided they are not in the driver’s direct line of sight or too close to the edge of the windscreen. If a chip is large, deep, or located in a critical area, a full windscreen replacement may be recommended.
Benefits Of Repairing Chips Quickly
Addressing a chip as soon as possible can save time and money. Repairs are often quicker and cheaper than replacements, and fixing the damage early prevents it from getting worse.
How Are Windscreen Cracks Repaired?
Dealing with cracks is more challenging than repairing chips, and in many cases, replacement is the only option.
Repair Or Replace?
While very small cracks may be repaired using a similar resin-filling process as chips, most cracks require a full windscreen replacement. This is because cracks weaken the structural support of the windscreen and are more likely to spread, even after being repaired.
Costs & Time Involved
A crack repair or replacement usually takes longer and costs more than fixing a chip. However, leaving a crack untreated can result in even higher costs if the damage worsens or affects the vehicle’s MOT.
Importance Of Acting Quickly
Driving with a cracked windscreen is unsafe and can be illegal. Cracks can grow larger over time, especially if exposed to temperature changes or vibrations, so acting quickly is vital.
Why It’s Important To Address Windscreen Damage Quickly
Ignoring windscreen damage can lead to bigger problems, both in terms of safety and costs.
Safety Risks
Chips and cracks weaken the windscreen, reducing its ability to protect you in the event of a collision. Cracks, in particular, can compromise the structural integrity of your car and obstruct your view of the road.
Preventing Further Damage
Taking simple steps to protect your windscreen while waiting for repairs can help prevent the damage from worsening. For example, covering a chip with clear tape can keep out dirt and moisture, while avoiding sudden temperature changes can reduce the risk of cracks spreading.
Saving Time & Money
Repairing chips and cracks early is almost always quicker and cheaper than replacing the entire windscreen. Many insurers also cover the cost of repairs, so check your policy to see if you’re eligible for a no-cost or low-cost repair service.
