Auto glass is an essential part of your vehicle’s safety system, protecting you from the elements, keeping your view of the road clear, and contributing to the overall structural integrity of your car. A well-maintained windshield ensures that you can drive safely and comfortably. However, cracks and chips in auto glass are a common issue that many vehicle owners face. Whether it’s caused by a stray rock on the highway or a sudden temperature change, a small chip can easily turn into a large crack if not addressed in time.
Many drivers wonder, “Can auto glass repair crack further after being fixed?” It’s a question that highlights the uncertainty around the durability of glass repairs and whether they can withstand the rigors of daily driving. In this blog post, we’ll explore how auto glass damage happens, the repair process, why cracks may still appear or worsen after repair, and when you should consider replacement instead.
At Northwest Houston Auto Repair Heights and Collision Center, we’re committed to helping our customers understand the best solutions for their auto glass issues, ensuring you have the knowledge to make informed decisions about your vehicle’s safety.
Understanding Auto Glass
To truly grasp the challenges of auto glass repair, it’s important to first understand how auto glass is designed and how it functions in your vehicle.
Most modern vehicles are equipped with two primary types of glass: laminated and tempered glass. These materials are engineered to provide a combination of visibility, protection, and safety, but each reacts differently when damaged.
- Laminated Glass: This type of glass is used primarily for windshields. It’s made by bonding two layers of glass with a plastic interlayer. This construction not only keeps the glass from shattering into dangerous shards upon impact but also maintains the overall structural integrity of the vehicle in the event of a crash. In fact, the windshield accounts for up to 45% of your vehicle’s structural strength in a front-end collision, and up to 60% in a rollover accident.
- Tempered Glass: Unlike laminated glass, tempered glass is used for side and rear windows. It’s designed to shatter into small, less dangerous pieces upon impact. This minimizes the risk of injury in an accident, but it also means that when this type of glass is damaged, it cannot be repaired and must be replaced.
The most common causes of auto glass damage include:
- Flying debris: Small rocks, gravel, or other objects can be kicked up by other vehicles on the road, striking your windshield and causing chips or cracks.
- Sudden temperature changes: Rapid shifts in temperature can cause the glass to expand or contract, leading to stress cracks. This is why you should avoid washing your car with hot water in cold weather or blasting the heater on a freezing day without allowing the windshield to adjust gradually.
- Accidents or minor collisions: Even a small fender bender can result in windshield damage.
- Frame stress: If your vehicle’s frame is misaligned, it can place uneven pressure on the glass, leading to cracks over time.
Common Types of Auto Glass Damage
Auto glass damage comes in many forms, and understanding the type of damage you have is crucial in determining whether it can be repaired or if replacement is necessary. The two most common types of damage are chips and cracks, but there are multiple subtypes within each category.
- Chips: Chips are small areas of damage caused by an impact from debris. While they may seem minor, they can eventually spread into larger cracks if not repaired promptly. Common types of chips include:
- Star Chip: This type of chip has a central point with lines radiating out, resembling a star. It’s usually repairable if caught early.
- Bullseye: A circular chip with a darker center, resembling a bullseye target. This is one of the most common forms of damage and is often repairable.
- Combination Chip: A chip that has multiple characteristics, such as a bullseye with additional cracks extending from the center. Repair is possible, but these are more complex and may require immediate attention.
- Cracks: Cracks are larger than chips and can spread across the entire windshield if left untreated. Common types of cracks include:
- Stress Cracks: These occur without any direct impact and are usually caused by temperature changes or structural stress within the vehicle. Stress cracks often require replacement because they compromise the overall integrity of the glass.
- Edge Cracks: Cracks that begin at the edge of the windshield and spread inward are known as edge cracks. These are typically longer and can worsen quickly. Depending on the size and location, an edge crack may be repairable, but it’s often best to replace the glass.
- Floater Cracks: These cracks occur in the middle of the windshield and are not connected to the edges. Floater cracks are more likely to be repairable if they’re less than six inches long.
- Long Cracks: Any crack longer than six inches is generally considered a long crack. In most cases, long cracks cannot be repaired, as the structural integrity of the glass is too compromised.
In determining whether to repair or replace the damaged glass, several factors are considered, including the size of the damage, the type of damage, and the location. Cracks that are in the driver’s direct line of sight are more likely to require replacement because even a minor flaw can distort vision, making driving dangerous.
The Auto Glass Repair Process
Once you’ve determined that your windshield or other auto glass is damaged, it’s time to explore your repair options. At Northwest Houston Auto Repair Heights and Collision Center, we use advanced techniques to ensure that your glass is repaired safely and efficiently.
The first step in the repair process is an inspection. Our trained technicians will assess the damage to determine if it can be repaired or if a replacement is necessary. For minor chips and cracks, the repair process involves several key steps:
- Preparation and Cleaning: Before any repair can begin, the damaged area must be thoroughly cleaned. Dirt, debris, and moisture can prevent the resin from bonding properly with the glass, so this step is critical.
- Resin Injection: Once the area is clean, a special clear resin is injected into the damaged area. This resin fills in the cracks and chips, restoring the glass’s integrity.
- Vacuum and Pressure Application: In some cases, vacuum and pressure techniques are used to remove air from the crack and help the resin penetrate more deeply into the damaged area. This ensures a stronger bond.
- UV Curing: After the resin has been injected, UV light is used to cure or harden the resin. This process only takes a few minutes and ensures that the repair will hold up over time.
- Polishing: Once the resin has cured, the surface of the repaired area is polished. This step helps to make the repair less noticeable and restores the smooth finish of the glass.
While many auto glass repairs can be completed in under an hour, the process should never be rushed. A professional repair will ensure that the glass remains safe and functional for as long as possible. It’s also important to note that a proper repair will prevent the damage from spreading, which can save you from needing a full replacement later on.
When Auto Glass Repair Can Fail
While most auto glass repairs are successful, there are cases where the repair may not hold or the crack may reappear. This can happen for several reasons:
- Severe Temperature Fluctuations: Extreme changes in temperature can cause the glass to expand and contract. If the repaired area is exposed to high heat or extreme cold shortly after the repair, the bond between the resin and the glass may weaken, causing the crack to spread again.
- Vehicle Stress: If your vehicle’s frame is bent or under stress, it can place uneven pressure on the windshield, making it more likely that the repaired area will fail. This is particularly common in older vehicles or those that have been involved in accidents.
- Improper Repair Techniques: Not all repair services are created equal. If the repair wasn’t done properly or if inferior materials were used, the repair might not last. That’s why it’s so important to choose a trusted, professional service like Northwest Houston Auto Repair Heights and Collision Center.
When Auto Glass Replacement is Necessary
In some cases, repair isn’t an option, and the auto glass will need to be replaced entirely. Some of the most common scenarios that require replacement include:
- Damage in the Driver’s Line of Sight: If a crack or chip is located directly in the driver’s field of vision, repair may not be safe or effective. Even the best repairs can leave minor distortions that could impede your ability to see the road clearly, which is why replacement is often recommended.
- Cracks Larger than Six Inches: Most experts agree that cracks longer than six inches can’t be effectively repaired. Larger cracks compromise the windshield’s structural integrity, making it more prone to shattering.
- Damage to the Edge of the Windshield: Cracks or chips near the edge of the glass are more likely to spread quickly, and repairs may not be able to stop this process. In such cases, replacement is often the safer choice.
