Myth 1: A Small Chip or Crack Is No Big Deal

It’s easy to overlook a small chip on your windshield. It may seem like a minor cosmetic problem that you can handle at a later time. However, this is one of the most dangerous misconceptions about auto glass. In addition to providing wind and rain protection, a windshield is an essential structural element of your car.

It offers up to 60% of the cabin’s structural integrity during a rollover accident and supports the proper deployment of passenger-side airbags. Even a minor chip can compromise this structural integrity. A small chip can grow into a large crack that obstructs your vision and weakens the glass due to temperature changes, road vibrations, and even hitting a pothole.

What could have been a simple and affordable repair can quickly turn into a full, more expensive windshield replacement. Repairing damage as soon as it occurs is crucial for preserving your car’s safety features and preventing more significant costs later on.

Myth 2: DIY Windshield Repair Kits Are Just as Good as Professional Service

DIY windshield repair kits are readily available and often marketed as a cheap and easy alternative to professional service. While it might be tempting to save a few dollars and fix a chip yourself, these kits rarely provide a permanent or safe solution.

Professional technicians have specialized tools, high-quality resins, and extensive training that a DIY kit simply cannot replicate. The technique of mending a chip entails injecting a specific resin into the damaged region and then curing it with UV radiation to form a strong, transparent connection.

The quality of the resin and the precision of the application are important for a successful repair. DIY kits often contain lower-quality materials and lack the vacuum-pressure tools needed to remove all the air from the chip, resulting in a weak and visually imperfect repair. An improper repair can also fail over time, causing the crack to spread and making a future professional repair impossible, leaving a full replacement as the only option.

Myth 3: All Auto Glass Is Created Equal

When it comes to windshield replacement, many people assume that any piece of glass will do, as long as it fits their car. Nothing is more untrue than this. The difference between OEM (original equipment manufacturer) glass and aftermarket glass is substantial.

OEM Glass: Made by the same company that provided your car’s original glass, this is known as OEM glass. It meets the exact specifications for thickness, color, shape, and durability, ensuring a perfect fit and optimal performance of your car’s safety systems.

Aftermarket Glass: This is made by different companies, and while it must meet certain federal safety standards, it may not match the precise quality and specifications of OEM glass.

Variations in thickness or shape can lead to wind noise, leaks, or even interference with the sensors for Advanced Driver-Assistance Systems (ADAS) that are often mounted on modern windshields.

For a guaranteed fit and to ensure all your car’s features function correctly, choosing OEM-quality glass installed by a reputable professional is always the best choice.

Myth 4: Filing an Insurance Claim for Windshield Replacement Will Raise My Rates

One of the biggest hesitations for drivers considering a windshield replacement is the fear that filing an insurance claim will cause their premiums to skyrocket. Fortunately, this is generally not the case.

Most auto insurance policies include comprehensive coverage, which typically covers damage to your vehicle that isn’t caused by a collision, including glass damage from rocks or debris. In many states, insurance companies are prohibited from raising your rates for a single “no-fault” comprehensive claim like a windshield repair.

Some insurers even waive the deductible for windshield repairs to encourage drivers to fix small chips before they become major problems. It’s always a good idea to check your specific policy details, but in most situations, using your insurance for a windshield replacement is a cost-effective option that won’t penalize you with higher premiums.

Myth 5: You Can Drive Your Car Immediately After a Windshield Replacement

Once the windshield has been replaced, you may be itching to drive again. However, the adhesive used to bond the windshield to the car’s frame needs time to cure and form a strong, watertight seal. This curing process is critical for your safety. A properly installed windshield is a key safety component, and driving too soon can compromise the bond.

Professional installers will provide you with a “safe drive-away time,” which is the minimum amount of time you need to wait before the vehicle is safe to operate. This time can vary from as little as 30 minutes to several hours, depending on the type of adhesive used and environmental conditions like temperature and humidity.

Following your technician’s instructions is vital to ensure the windshield performs as it should in the event of an accident.

Myth 6: Any Auto Shop Can Handle a Windshield Replacement 

While many auto repair shops offer windshield replacement services, not all are equipped to do the job correctly, especially for modern vehicles.

Advanced Driver-Assistance Systems (ADAS), composed of cameras and sensors mounted on the windshield, are common in modern cars and regulate functions such as adaptive cruise control, automatic emergency braking, and lane-keeping assist.

These ADAS systems need to be recalibrated to work properly after a windshield replacement. A camera that is off by even a single millimeter can fail to detect road hazards correctly.

Only authorized professionals with the right equipment and training may execute this sensitive recalibration operation. Choosing a specialized auto glass shop that is certified in ADAS recalibration ensures that your vehicle’s safety features will work as intended after the replacement.

Myth 7: The Only Purpose of a Windshield Is to Block Wind and Rain

As mentioned earlier, the windshield’s role goes far beyond just protecting you from the elements.

An essential component of your car’s safety restraint system, the windshield helps support the roof in a rollover accident, keeping it from collapsing and crushing the occupants, and it acts as a backstop for the passenger-side airbag in a front-end collision, ensuring it deploys correctly toward the passenger.

A compromised or improperly installed windshield can fail during an accident, drastically increasing the risk of serious injury. Thinking of it as just a window is a mistake; it’s a vital piece of safety equipment.

Myth 8: Windshield Replacement Is Always Extremely Expensive

The make and model of your car, the kind of glass (Original Equipment Manufacturer vs. aftermarket), and whether ADAS recalibration is required can all have a significant impact on the cost of a windshield replacement. While it can be a significant expense, it doesn’t always have to break the bank.

As previously said, your motor insurance might pay for all or most of the expenses. Even if you’re paying out of pocket, shopping around for quotes from reputable auto glass shops can help you find a competitive price.

Remember that opting for a cheap, low-quality installation can lead to more significant problems and costs down the road, such as leaks, wind noise, or safety system failures. You may invest in both your safety and the longevity of your car by hiring a qualified professional to replace your windshield.

Choosing to Repair or Replace

Not all chips and cracks necessitate a complete windshield replacement. The decision often depends on the size, location, and type of damage. 

When a Repair Is Possible: If the damage is minor and hasn’t interfered with the driver’s direct line of sight, a repair is usually a good option. Most technicians agree on the “dollar bill rule”: if the chip or crack can be covered by a dollar bill (roughly 6 inches long for a single crack or 1.25 inches in diameter for a chip), it can likely be repaired.

Benefits of Repair: Repairing is faster, more affordable, and better for the environment since it keeps the original glass out of a landfill. A unique resin is injected into the damaged area, where it cures and restores the strength and clarity of the windshield. 

When a Replacement Is Necessary:A replacement becomes unavoidable under certain conditions that compromise the safety and integrity of the vehicle. 

Size and Depth: Chips that have pierced deeply into the glass or cracks longer than a dollar bill typically need to be replaced completely. 

Location: Damage that is directly in the driver’s line of sight poses a serious safety risk. Even a flawless repair can leave a slight distortion that can be distracting. Additionally, cracks that extend to the edge of the windshield weaken its structure and warrant a replacement. 

Multiple Cracks: If your windshield has three or more separate chips or cracks, replacing it is often the safest and most practical solution.

Understanding Your Auto Glass

Not all auto glass is created equal. The glass in your vehicle is specifically engineered for safety, and understanding the different types can help you appreciate why proper replacement is so important. 

Laminated safety glass for windshields: Laminated glass is used to make your windshield. This is made up of two glass layers sandwiched by a thin layer of plastic, usually polyvinyl butyral (PVB).

This design keeps the glass from breaking into sharp fragments in the case of an impact. Instead, the pieces stick to the PVB layer, holding the windshield together and protecting the vehicle’s occupants. In the event of a rollover, this structure also supplies up to 60% of the cabin’s strength. 

Windows on the sides and back: tempered glass Tempered glass is typically used for the side and rear windows. This type of glass is treated with heat and then rapidly cooled, making it about four times stronger than regular glass.

When it breaks, tempered glass shatters into small, pebble-like pieces with dull edges, which are far less likely to cause serious injury than the large, jagged shards of standard glass.

What Distinguishes OEM from Aftermarket Glass

When you get your glass replaced, you usually have two options:

OEM glass: which is made by the same company that made the original glass for your car and is identical in every way—size, shape, thickness, color, and durability. Since it’s a direct replacement, it guarantees a perfect fit. 

Aftermarket Glass (OEE): This stands for “Original Equipment Equivalent” and is made by companies that don’t have a contract with your car’s manufacturer. Although these must meet federal safety standards, their quality varies; some aftermarket glass is excellent, while some may have slight variations in fit or clarity. 

Although aftermarket glass is frequently less expensive, using OEM glass guarantees that you’re returning your car to its factory specifications, which is especially important for newer cars with advanced safety features.

The Effect on Complex Driver-Assistive Technology (ADAS)

Advanced Driver-Assistance Systems (ADAS), such adaptive cruise control, front collision warnings, and lane-keeping assistance, are becoming more and more common in modern automobiles. The windshield is where a large number of these systems’ cameras and sensors are installed.

These systems need to be recalibrated when a windshield is replaced on an automobile equipped with ADAS. Recalibration is not optional; it is a critical safety step. If the sensors are even slightly misaligned, the ADAS features may not function correctly, which could lead to dangerous situations on the road.

Ensure the auto glass shop you choose has the technology and expertise to perform ADAS recalibration. A reputable technician will always include this as part of the replacement service for any ADAS-equipped vehicle.

Selecting a Skilled Technician

Just as crucial as the quality of the glass itself is the installation’s quality. A poorly installed windshield can leak, create wind noise, or even pop out during a collision, seriously compromising your safety.

Choose a store that has qualified technicians on staff. Groups such as the Auto Glass Safety Council (AGSC) offer certification and enforce strict safety and quality requirements for their members.

The industry standard is a high-quality, fast-curing urethane, so don’t be afraid to inquire about the credentials of their specialists and the kind of glue they employ.

Your Next Steps for a Safe Replacement

Facing a cracked windshield can be stressful, but knowing the right steps to take makes the process much smoother. Prioritize safety by assessing the damage correctly, understanding the materials involved, and insisting on proper ADAS recalibration.

By choosing a certified technician and quality materials, you ensure your vehicle remains as safe as the day it left the factory. Don’t delay—addressing glass damage promptly protects you, your passengers, and your investment.
