Windscreen Repair vs. Replacement: How to Decide the Best Option for Your Car

A damaged windscreen can be a major inconvenience and a potential safety hazard. Whether it’s a small chip or a larger crack, it’s crucial to address the issue promptly to maintain the integrity and safety of your vehicle. But how do you decide whether to repair or replace your windscreen? In this blog, we’ll explore the key factors to consider when choosing between windscreen repair and replacement, helping you make an informed decision for your car.

Understanding Windscreen Damage

Before deciding on the best course of action, it’s important to understand the types of windscreen damage and their implications:

Types of Windscreen Damage

  1. Chips: Small areas of damage are usually caused by debris hitting the windscreen. They can vary in size and shape but are generally less than 25mm in diameter.
  2. Cracks: Larger, more linear breaks in the glass. Cracks can spread quickly, compromising the structural integrity of the windscreen.
  3. Bullseye: A circular damage pattern caused by a direct impact, resembling a target with concentric rings.
  4. Star Break: A series of short radial cracks stemming from a central point of impact.

When to Choose Windscreen Repair

Size and Location of Damage

The size and location of the damage are critical factors in determining whether a repair is feasible:

  • Small Chips and Cracks: Generally, chips less than 25mm and cracks less than 100mm can be repaired.
  • Away from the Driver’s Line of Sight: If the damage is located outside the driver’s direct line of sight, repair is often the preferred option. Repairs can sometimes leave slight distortions that could affect visibility if located directly in front of the driver.


Repairing a windscreen is typically more cost-effective than replacing it. Repair costs are usually lower and many insurance policies cover windscreen repairs with minimal or no deductible.

Time Efficiency

Windscreen repairs are quick and convenient, often taking less than 30 minutes. This makes it a practical option for busy individuals who need a fast solution.

Environmental Considerations

Repairing your windscreen is also more environmentally friendly. It reduces the need for new glass production and minimizes waste, contributing to environmental sustainability.

When to Choose Windscreen Replacement

Extent of Damage

Larger cracks and extensive damage typically require a full replacement. If the crack is longer than 100mm or if the chip is larger than 25mm, replacement is usually necessary.

Location of Damage

  • Driver’s Line of Sight: If the damage is directly in the driver’s line of sight, replacement is often recommended to ensure optimal visibility and safety.
  • Edges of the Windscreen: Damage near the edges can compromise the structural integrity of the windscreen, increasing the risk of the glass shattering. In such cases, replacement is the safer option.

Structural Integrity

The windscreen is an integral part of your vehicle’s structural integrity, particularly in the event of a rollover accident. Severe damage can weaken the windscreen, making replacement essential to ensure the safety of the occupants.

Safety Considerations

A compromised windscreen can impair visibility and increase the risk of accidents. If the damage significantly affects your visibility or poses a safety risk, replacement is the best option.

The Repair Process

Assessing the Damage

A professional technician will assess the extent of the damage to determine if repair is possible. This involves examining the size, depth, and location of the chip or crack.

Repair Technique

The technician will use a specialized resin to fill the chip or crack if the damage is deemed repairable. The resin is then cured using ultraviolet light, restoring the integrity of the windscreen.

Final Inspection

After the repair is completed, the technician will inspect the windscreen to ensure the repair has been successful and that the structural integrity has been restored.

The Replacement Process

Removing the Damaged Windscreen

The damaged windscreen is carefully removed using specialized tools to avoid damaging the vehicle’s bodywork.

Preparing the Frame

The windscreen frame is cleaned and prepped to ensure a proper seal for the new glass. Any old adhesive is removed, and a new primer is applied.

Installing the New Windscreen

A new windscreen is carefully fitted into place using high-quality adhesive. The adhesive is allowed to cure to ensure a strong bond.

Final Inspection and Safety Check

Once the new windscreen is installed, a thorough inspection is conducted to ensure the installation meets safety standards. The vehicle is checked for leaks and the windscreen’s alignment is verified.


Deciding between windscreen repair and replacement depends on several factors, including the extent and location of the damage, cost considerations, and safety implications. Repair is often a quick, cost-effective, and environmentally friendly option for minor damage, while replacement is necessary for more severe damage to ensure safety and structural integrity.
