A cracked windshield is a frustrating and potentially dangerous issue. Knowing whether it's repairable or requires full replacement can save you time and money. The size and type of crack are the primary factors determining repairability. This guide will help you understand the limitations of windshield crack repair and when replacement is necessary.
What Types of Windshield Damage Can Be Repaired?
Generally, small chips and cracks are the best candidates for repair. We're talking about damage less than the size of a quarter, ideally. The specific criteria often depend on the individual auto glass repair technician, but these are common guidelines:
- Small Chips: These are the easiest to fix and usually involve injecting resin into the chip to fill and seal it.
- Cracks (Spider Webs): Small cracks radiating from a central point (like a spiderweb) can often be repaired, provided the cracks aren't excessively long or have significant branching.
- Small Star-shaped Breaks: Similar to spiderwebs, these are sometimes repairable depending on size and overall integrity.
Crucially, the crack shouldn't extend into the driver's direct line of sight. Safety is paramount; if the crack impairs visibility, repair is unlikely to be sufficient.
What Size Cracks Typically Require Windshield Replacement?
Windshield replacement is usually necessary when the damage is:
- Larger than a quarter: Cracks exceeding this size often have a higher risk of spreading further, compromising the structural integrity of the windshield.
- Cracks that extend into the driver's line of sight: Even a smaller crack directly in your vision should be replaced.
- Cracked or damaged area near the edges of the windshield: These areas are often too close to the frame for effective repair.
- Cracks that are heavily pitted, jagged, or branched: These are much harder to repair effectively and may leave visible imperfections.
- Cracks with embedded debris: If the crack has dirt or other material lodged in it, it's difficult to completely clear and achieve a flawless repair.
Can a Windshield Crack Spread After Repair?
Sometimes, despite a successful repair, a crack can spread, particularly if subjected to stress, such as extreme temperature changes or impacts. While repair significantly reduces this risk, it doesn't eliminate it completely. Regularly check your windshield after a repair for any signs of spreading.
How Much Does Windshield Crack Repair Cost?
The cost of windshield crack repair is typically much less than replacement. Prices vary by location and the severity of the damage, but it usually ranges from $60-$150.
Can I Repair My Windshield Myself?
While DIY windshield repair kits exist, they are generally not recommended for anything beyond the smallest chips. Professional repair technicians possess the expertise and specialized tools to achieve the best results and ensure a safe repair. A poorly executed repair can worsen the damage and even lead to safety concerns.
What Happens if I Don't Repair a Crack?
Ignoring a crack can lead to several problems:
- Further cracking: The crack can spread, potentially requiring a more expensive replacement later.
- Reduced structural integrity: A compromised windshield is less able to withstand impacts in an accident, reducing overall safety.
- Impaired visibility: A large or strategically placed crack can significantly reduce your visibility.
- Failure to pass vehicle inspection: Depending on your region, a large crack may result in a failed vehicle inspection.
