Windscreen Chips & Cracks: Repair or Replace?

It's a common, and often startling, occurrence for drivers: that moment you hear the sharp ping of a stone or other debris striking your windscreen, leaving behind a chip or, worse, a crack. While it's easy to dismiss a minor chip as merely an aesthetic issue, the reality is that damage to your windscreen can have significant implications for your safety, the structural integrity of your vehicle, and even your ability to pass your MOT test. At Steve's Windscreens Ltd, we understand the concern this causes, and we're here to guide you through the best course of action, whether it's a swift repair or a full replacement.

Understanding Windscreen Damage: Chips vs. Cracks

Before we delve into solutions, it's crucial to differentiate between a chip and a crack, as the repairability often depends on the type and size of the damage.

Windscreen Chips

A windscreen chip typically occurs when a small, solid object strikes the glass. The impact often causes a small piece of glass to be dislodged, leaving a small pit or crater. Common shapes for chips include the 'bullseye' (a circular impact with a cone-shaped break), the 'star break' (multiple small cracks radiating from the impact point), and the 'combination break' (a mix of bullseye and star patterns).

Windscreen Cracks

Cracks are usually longer and more linear than chips. They can start from an impact point and extend across the glass, or they can appear spontaneously due to stress, temperature changes, or pre-existing damage. Cracks can be anything from a short line to a long fissure that spans a significant portion of the windscreen.

When Can a Windscreen Chip Be Repaired?

The good news is that many windscreen chips can be successfully repaired, saving you the cost and hassle of a full replacement. However, there are limitations. Generally, a chip can be repaired if:

• The chip is smaller than a £2 coin (approximately 25mm in diameter).
• The damage is not directly in the driver's line of sight. Damage in this area can impair visibility and lead to an MOT failure.
• The chip has not reached the edge of the windscreen, as this can compromise the structural integrity.
• The damage is not too deep, meaning it hasn't penetrated both layers of the laminated glass.

The Windscreen Repair Process

Windscreen chip repair is a highly effective process that involves injecting a special resin into the damaged area. This resin is optically matched to the glass and, once cured under UV light, it bonds the glass fragments together, restoring the windscreen's strength and clarity. The process is relatively quick, often taking less than an hour, and significantly reduces the risk of the chip spreading.

The steps typically involve:

1. Cleaning the area: The damaged area is thoroughly cleaned to remove any dirt or debris.
2. Drilling (if necessary): In some cases, a tiny hole may be drilled at the tip of the crack or chip to relieve pressure and prevent further spreading.
3. Vacuum and Injection: A special tool is used to create a vacuum within the chip, drawing out air. Then, the clear resin is injected under pressure.
4. Curing: The resin is cured using a UV light, hardening it and bonding the glass.
5. Polishing: The repaired area is then polished smooth to remove any excess resin and ensure a clear finish.

When is Windscreen Replacement Necessary?

While repairs are preferable when possible, there are instances where a full windscreen replacement is the only safe and viable option. These include:

• Large Cracks: Cracks longer than 15cm (around 6 inches) generally cannot be repaired and will require replacement.
• Damage in the Driver's Line of Sight: Any damage that obstructs the driver's clear view of the road, regardless of size, will necessitate a replacement to ensure road safety and compliance with MOT regulations.
• Damage to the Edges: If a chip or crack extends to the edge of the windscreen, it compromises the structural integrity, and replacement is usually required.
• Multiple Chips or Cracks: A windscreen with numerous chips or a combination of chips and cracks may be too weakened to repair effectively.
• Compromised Lamination: If the laminated glass has been significantly damaged or delaminated, it will need replacing.

The Windscreen Replacement Process

Replacing a windscreen is a more involved process, but our expert technicians at Steve's Windscreens Ltd ensure it's carried out efficiently and to the highest standards. Modern windscreens are a critical structural component of a vehicle, contributing significantly to the car's safety, particularly in the event of a collision or rollover. The airbag system also relies on the windscreen for proper deployment.

The replacement process typically involves:

1. Removal of Old Windscreen: The damaged windscreen is carefully cut out of the vehicle's frame using specialised tools.
2. Cleaning and Preparation: The aperture (the opening for the windscreen) is thoroughly cleaned, and any old adhesive is removed. A primer is applied to the frame to ensure optimal adhesion of the new windscreen.
3. Fitting the New Windscreen: A high-quality replacement windscreen is bonded into place using a strong, automotive-grade adhesive.
4. Curing and Refitting: The adhesive is allowed to cure for a specified period, after which any remaining trim pieces are refitted, and the vehicle is ready to be returned to you.

The Importance of Prompt Action

It's vital to address windscreen damage as soon as you notice it. Even a small chip can, under the right conditions, quickly develop into a larger crack. Factors that can exacerbate damage include:

• Temperature Fluctuations: Extreme heat or cold can cause the glass to expand and contract, putting stress on existing chips and cracks, encouraging them to spread.
• Vibrations: The constant vibrations from driving, especially over rough roads, can also cause damage to worsen.
• Washing the Vehicle: The high-pressure water used in some car washes can force its way into small chips, widening them.

Acting quickly not only increases the likelihood of a successful repair but also prevents potentially more costly repairs or replacements down the line.

Frequently Asked Questions

Q1: Can I drive with a chipped windscreen?

A1: It is generally safe to drive with a small chip if it is not in your line of sight and doesn't appear to be spreading. However, it's advisable to get it inspected and repaired as soon as possible to prevent it from worsening.

Q2: Will my insurance cover windscreen repair or replacement?

A2: Many insurance policies include cover for windscreen damage, often with a low or no excess for repairs. It's best to check with your insurance provider. We can also assist with the insurance claim process.

A3: A typical windscreen chip repair takes approximately 30-60 minutes.

Q4: How long does a windscreen replacement take?
