How Do You Fix a Cracked Windscreen?



The windscreen, or windshield as it is called in some regions, plays an essential role in the structural integrity and safety of a vehicle. When your windscreen gets cracked, it is not just an aesthetic concern but can be a safety hazard as well. Acting promptly to address the issue can save you from further complications down the road. Here is how you can approach fixing a cracked windscreen.


1. Assess the Damage

Before embarking on any repair procedures, it is essential to assess the extent of the damage. There are primarily three types of windscreen damages:


Chip: A small piece of glass has been removed from the surface.
Crack: A line on the windscreen which can vary in length.
Bullseye: A circular damage on the windscreen.


It is vital to ascertain if the damage is repairable. Typically, chips smaller than a quarter and cracks up to three inches long can be repaired. However, if the damage is in the driver’s line of sight or the crack has splintered, replacement might be necessary.


2. Safety First

If the crack is too large or situated in critical areas, it could compromise the integrity of the windscreen. In such cases, avoid driving the vehicle until it has been addressed. The windscreen provides structural strength to the car, especially in situations like rollovers. A damaged one can shatter easily, putting the occupants at risk.


3. DIY Repair or Professional Assistance

There are DIY kits available in the market to fix minor windscreen damages. These kits contain a resin that fills up the crack or chip, restoring the windscreen’s clear appearance and its structural strength. Here is a basic rundown of how to use them:


Clean the Area: First, clean the damaged area with a glass cleaner to remove dirt and debris.
Application of Resin: The DIY kit will usually come with a tool that helps you fill the crack or chip with a special resin.

Curing: After the resin has been applied, it must be cured. UV light is frequently used to do this. While some kits require you to park your car in direct sunshine, others may come with a UV lamp.
Scrape Off Extra Resin: To create a smooth and level surface when the resin has dried, any extra can be scraped off with a razor blade.


While DIY kits can be effective for minor damages, there is no substitute for professional repairs. If you are unsure about the extent of the damage or do not feel confident doing it yourself, seek out a professional. They possess the tools, expertise, and high-quality materials to ensure a long-lasting repair.


Insurance and Cost Considerations

Before you go ahead with the auto glass repair or replacement, it is a clever idea to check your vehicle insurance policy. Many policies cover windscreen repairs without affecting your no-claims bonus. The cost of repair is lower than the cost of replacement, so if the damage is repairable, it is a more economical option.


Windscreen Replacement

If the crack is too extensive, or the damage cannot be fixed without compromising visibility or safety, then replacement is the only option. Professionals will remove the damaged  windscreen and replace it with a new one that meets or exceeds the original equipment manufacturer’s specifications.


Preventive Measures

While not all windscreen damages can be avoided, some steps can reduce the risk:


Avoid Direct Sunlight: Parking in the shade can reduce the chances of temperature fluctuations, which can stress the windscreen.
Maintain Distance: While driving, maintain a safe distance from vehicles, especially heavy-duty trucks that might fling debris.
Avoid Sudden Temperature Changes: Using hot water to de-ice a frozen windscreen can cause it to crack due to the sudden temperature change.

A cracked windscreen can be a real hazard, and it is essential to address it promptly. While minor cracks and chips can be fixed with DIY kits or professional repairs, larger or more complicated damages will require a full replacement. Always prioritize safety, and when in doubt, consult with a professional to determine the best course of action. Regular vehicle check-ups and adhering to preventive measures can also help in prolonging the life of your windscreen.
