There was a time when chips or cracks in a windshield meant replacement. Now it’s a lot harder to know when to repair or replace windshields. Modern technology makes it possible to repair windshields that would have previously been scrapped. Not only does this save your windshield, it also saves you money. But be aware that even the most advanced glass repair techniques have their limits. So if your windshield is severely damaged, new glass may still be in your future. Do I have to replace my windshield or can it be repaired? Windshield repair or replacement depends on the size, location and severity of the damage. The majority of windshield repair shops can repair quarter-sized rock chips and cracks up to three inches long. Anything bigger and most places will recommend replacement. However, some facilities use a special technique that allows them to repair cracks up to 12 inches long. So it pays to check around before committing to a new windshield. Location of the damage also plays an important role in determining your windshield’s fate. Cracks at the edge of the windshield tend to spread very quickly and can compromise the structural integrity of the glass. If they’re caught in time, they can be repaired. But in most cases, it’s usually advisable to replace the windshield. Also be aware that some facilities may not repair a chip that appears directly in the driver’s line of vision. Because the repair process leaves minor distortions in the glass, some shops prefer to replace the windshield rather than compromise the driver’s vision. Regardless of the size and location of a chip or crack, it’s always advisable to have it repaired quickly. If you wait some time to repair it, dirt can work its way into the damaged area, affecting the effectiveness and clarity of the repair. Finally, bear in mind that if your windshield took a big enough hit, it may simply be beyond saving. Major impacts (BIG objects) or accident damage go beyond what any repair facility can fix. In these severe cases, replacement is a must. How much will this cost? The cost to repair a windshield is pretty standard across the country. According to an MSN Auto Survey, windshield repair facilities across the country are fairly consistent. Repairing a single rock chip costs around $40-$50 for the first chip, then usually $10 extra for each additional chip. The cost to repair most cracks is about the same. However, if the crack is longer than three inches, it may require special treatment. Long-crack specialist Novus typically charges about $70 to repair a six- to twelve-inch windshield crack. Windshield replacement costs considerably more and varies greatly depending on the vehicle. In addition to the cost of the windshield itself, a windshield molding kit and installation labor must be factored into the overall replacement cost.
