Should the cracked windshield be replaced?
4 Answers
If the windshield is cracked, it needs to be replaced. According to current glass repair equipment, cracks up to 30 centimeters can be repaired. For such long cracks, choosing repair is a better option if they are on the passenger side or not directly in front of the driver, as repairing excessively long cracks will leave a faint trace that may affect the driver's vision to some extent. Additionally, the sooner the windshield is repaired, the better the effect will be. The windshield is a vulnerable component, and it is common to encounter stones or hard objects during daily driving that may cause it to crack. Therefore, replacing the windshield is a normal occurrence.
The front windshield is cracked, and I strongly recommend replacing it as it affects safe driving. With over a decade of driving experience, I’ve seen small cracks expand easily at high speeds. The windshield is a critical structural component of the car—cracks reduce its crash resistance. If debris scatters, there’s a high risk of injury or obstructed vision. I once ignored a small crack, only for it to suddenly shatter during a heavy rainstorm at night, nearly causing a major accident due to blurred vision. Professionals say cracks in the driver’s line of sight or exceeding 15 cm must be replaced; ordinary repairs are only a temporary fix. Don’t skimp or delay—timely inspection and replacement can prevent greater losses. Life is priceless. Safety comes first, and now I make it a habit to regularly check my car’s glass.
As an average car owner, I weigh the pros and cons of replacing the windshield from an economic perspective. A small crack might be temporarily fixed with professional repair agents, costing just a few dozen yuan. However, if the crack is large or deep, replacement is necessary, typically ranging from a few hundred to over a thousand yuan. Last year, I had a crack and inquired with my insurance company—they said if I had glass coverage, it would be fully reimbursed; otherwise, paying out of pocket is still worth it, as cracks can expand on highways, and delaying replacement could cost more in the long run. DIY repairs are difficult to manage, so getting an evaluation from a reputable repair shop is the most hassle-free option. Although replacement is expensive, it’s a small cost compared to potential repair bills or accident risks. I tried repairing mine before, but the results were poor, and the crack kept reopening—replacing it once and for all was the better choice. For frequent drivers, don’t delay addressing windshield issues.
Whether to replace a cracked windshield depends on the type of crack. Small star-shaped cracks (less than 5 cm) may be repairable with resin to save costs; however, linear cracks or those exceeding 20 cm require replacement. The glass's structural integrity is compromised, making it prone to shattering on bumpy roads, posing safety risks. With some technical knowledge, I understand that cracks near the edges are harder to repair; fixes are only temporary. It's best to consult a professional shop for assessment using specialized tools.
