A Comprehensive Guide to Windshield Repair: When to Fix and When to Replace

A cracked windshield can be a frustrating and potentially dangerous issue for any driver. Not only can it obstruct your view of the road, but it can also compromise the structural integrity of your vehicle. In this article, we will provide a comprehensive guide to windshield repair, including when to fix and when to replace a damaged windshield. We will also discuss the various types of damage that windshields can sustain, the repair and replacement process, and how to prevent future damage.


Types of Windshield Damage:

The first step in determining whether your windshield needs to be repaired or replaced is to identify the type and severity of the damage. The most common types of windshield damage include chips, cracks, bullseyes, and stars. Chips are small dings in the glass, while cracks are larger breaks that can span the length of the windshield. Bullseyes and stars are a type of crack that features a circular or star-shaped pattern around the point of impact. Each of these types of damage requires a different approach to repair, so it’s important to understand the differences.


Repair vs. Replacement:

Once you have identified the type and severity of the damage, the next step is to determine whether your windshield can be repaired or if it needs to be replaced. In general, chips and cracks that are smaller than a quarter can usually be repaired, while larger cracks or damage that is in the driver’s line of sight will require a full windshield replacement. Other factors that can impact whether a repair or replacement is necessary include the location of the damage, the age and condition of the windshield, and the make and model of the vehicle.


Repair Process:

If a repair is possible, the process typically involves filling the damaged area with a clear resin that hardens and bonds with the glass. The technician will clean the damaged area and use a specialized tool to inject the resin into the crack or chip. The resin is then cured with an ultraviolet light, which creates a strong bond with the glass and prevents the damage from spreading. The repair process usually takes less than an hour and can be done in the technician’s shop or at your home or office.


Replacement Process:

If a replacement is necessary, the process is more involved and usually takes several hours to complete. The technician will remove the old windshield, clean the frame, and install a new windshield using a special adhesive. The adhesive typically takes several hours to cure, during which time you should avoid driving or exposing the vehicle to extreme temperatures or moisture. Once the adhesive has cured, the technician will clean and inspect the new windshield to ensure it is properly installed and sealed.


Preventing Future Damage:

To prevent future windshield damage, there are several steps you can take. First, be mindful of driving conditions and avoid following too closely behind other vehicles or driving on unpaved roads. Additionally, avoid parking in direct sunlight for extended periods of time, as heat can cause the glass to expand and contract, leading to cracks or chips. Finally, consider installing a windshield protection film or having your windshield coated with a protective layer to help prevent damage from rocks, debris, and other hazards.



A damaged windshield can be a serious safety issue for any driver, so it’s important to take action as soon as possible to repair or replace a damaged windshield. By understanding the types of damage, the repair and replacement process, and how to prevent future damage, you can ensure that your vehicle’s windshield remains safe and functional for years to come.
