How Many Times Can a Windscreen Be Repaired?



The windscreen or windshield is one of the most crucial parts of a vehicle, ensuring the safety of its occupants and providing clear visibility for the driver. Over time, it’s not uncommon for windscreens to accumulate chips or cracks due to debris on the road, minor accidents, or temperature fluctuations. The big question for many car owners is: how many times can a windscreen be repaired before it needs to be replaced? This is a pertinent question, especially when considering both safety and cost.


The Basics of Windscreen Repair

Before delving into the number of times a windscreen can be repaired, it’s essential to understand the basics of the repair process. A windscreen chip or crack repair typically involves the injection of a special resin into the damaged area, which is then cured using ultraviolet light. This process restores the structural integrity of the glass and improves its appearance. However, the repair doesn’t make the damage disappear entirely; rather, it prevents the crack or chip from expanding.


Factors Affecting Repairs

Various elements influence windscreen repair effectiveness, including damage size, location, and previous repairs, impacting decisions on repair versus replacement. Here are some factors that affect windscreen repairs.


Size and Type of Damage:

Not all damages to the windscreen are repairable. Small chips, usually less than the size of a coin, can often be repaired. Cracks that are less than three inches long are also generally repairable. However, long cracks, those that reach the edge of the windscreen, or complex starburst patterns may warrant a replacement instead of a repair.


Location of Damage:

Damage that is directly in the driver’s line of sight can be problematic. Even if the damage is repaired, it might still distort visibility. In such cases, replacement is often recommended. Similarly, cracks or chips close to the edge compromise the structural integrity of the windscreen, making replacement a safer option.


Number of Previous Repairs:

With each repair, the windscreen may become less resilient to further damage. This doesn’t mean the repair isn’t strong, but the glass around the repaired spot could become slightly more vulnerable. If a windscreen has multiple repair spots, especially close together, it may be more prone to developing new cracks.


How Many Times Can Windscreen Be Repaired?

There isn’t a one-size-fits-all answer. Theoretically, if a windscreen keeps getting small chips or cracks in different areas, and each is repairable, then it can be repaired multiple times. However, the more practical answer would consider a combination of factors like safety, aesthetics, and the strength of the windscreen.


For safety reasons, if there are more than three or four repairs, especially in the critical vision area, replacement might be a safer bet. Multiple repairs might clutter the driver’s vision, even if each individual repair is small. It’s also worth noting that as the number of repairs increases, the overall aesthetics of the windscreen can be compromised.


When to opt for Replacement Over Repair?

Beyond the number of repairs, consider these scenarios:


Depth of Damage:

Modern windscreens are made up of two layers of glass with a plastic layer in between. If the damage penetrates the inner layer, a repair won’t suffice.


Edge Cracks:

As previously mentioned, cracks that reach the edge of the glass can compromise its structural integrity. In such cases, a replacement is often recommended.



If a chip or crack has been left exposed for a long time and has been contaminated by dirt, it may be challenging to achieve a clear, successful repair.


Cost Considerations:

If your insurance covers windshield replacement, it might be financially wise to opt for a replacement after multiple repairs. Always check with your insurance company regarding their policy on repairs and replacements.
