What Does Resealing a Windshield Mean?
Resealing a windshield involves applying a new layer of adhesive or sealant around the edges to enhance its ability to protect the vehicle from the elements. While the adhesive may naturally wear over time due to exposure to temperature extremes, road salts, rain, and UV radiation, resealing provides a fantastic solution. It restores the windshield's tight seal, effectively preventing water leaks and reducing wind noise.
For example, a car owner in an area with frequent rain and humidity may notice small water leaks around their windshield. This signals that the sealant needs attention, and resealing offers a perfect, timely solution. However, if the windshield is cracked or chipped, opting for a full replacement ensures the highest level of safety and maintains the vehicle's overall integrity.
When Can You Reseal a Windshield?
Resealing is a great solution when the issue is limited to the sealant or adhesive, and there are no significant cracks or chips in the windshield itself. Here are a few common scenarios where resealing is the ideal choice:
Water Leaks: If water enters the vehicle during rain, it may simply be a sign that the seal can be improved. Resealing the windshield can effectively address this issue. For example, if water is pooling on the dashboard or near the base of the windshield, resealing provides a fast and efficient solution to restore a tight, secure seal.
Wind Noise: A noticeable increase in wind noise while driving may be caused by a loosening windshield seal. Resealing restores the tight fit, helping to bring back a quieter, more comfortable ride.
Edge Deterioration: With time, the adhesive around the edges of the windshield may undergo natural adjustments. When this happens, resealing is a highly effective and cost-efficient way to restore the windshield's secure fit, ensuring a tight and reliable seal for the long term.
In most cases, resealing a windshield can be completed in just a few hours, offering a quick and effective fix for minor issues.
When Is Resealing Not Enough?
While resealing is a great solution for minor issues, it's important to replace the windshield if it has cracks, chips, or deep dings to maintain the vehicle's safety. For instance, if a crack extends beyond 6 inches, replacing the windshield is the best course of action. The Auto Glass Safety Council (AGSC) advises replacing cracks or chips larger than a dollar bill to ensure the vehicle remains safe and secure.
Even smaller cracks can be addressed to avoid potential risks. A well-maintained windshield plays a key role in passenger safety, supporting the vehicle's structural integrity, especially in the case of a rollover. Replacing a damaged windshield ensures that your vehicle is always at its safest, providing confidence on every journey.
How Is a Windshield Resealed?
Resealing a windshield is a precise process that ensures the new sealant bonds securely and creates a durable, watertight seal. Here's how the process works:
Remove the Old Sealant: The technician carefully removes the old adhesive surrounding the windshield, preparing the surface for the new adhesive. This step is important for creating a strong, long-lasting bond with the new sealant.
Clean the Surface: Before applying the new adhesive, the area around the windshield is thoroughly cleaned. This ensures the new sealant bonds effectively by removing any dirt, moisture, or debris. In some cases, specialized tools such as pressure washers or air blowers are used to achieve a clean surface, ensuring the best possible adhesion.
Apply New Adhesive: A high-quality urethane-based adhesive or sealant is applied around the perimeter of the windshield. This adhesive creates a strong, flexible bond, ensuring the windshield remains securely in place for the long term. The technician applies it with precision to guarantee an even and secure fit.
Reinstall the Windshield: Once the new adhesive is in place, the windshield is carefully repositioned and aligned for a perfect fit. The technician ensures it is properly secured before allowing the adhesive to fully cure. The vehicle may need to sit for a few hours or overnight to ensure the adhesive sets completely, ensuring the windshield stays firmly in place.
This process ensures your windshield is resealed effectively, offering long-term durability and reliable protection.
Benefits of Resealing a Windshield
There are several benefits to resealing your windshield, particularly when the problem is confined to the adhesive and not the glass itself:
Cost-Effective: Resealing is far less expensive than replacing an entire windshield. Depending on the make and model of the vehicle, a full windshield replacement can cost anywhere from $200 to $1,000, whereas resealing typically costs between $50 and $150.
Quick Fix: Resealing is a faster option than a replacement. In many cases, it can be done in a few hours, so you won't have to worry about being without your car for a prolonged period.
Preserving the Windshield: If the windshield is otherwise undamaged, resealing can help preserve it for years to come. Instead of paying for a full replacement, resealing the existing windshield can restore its performance and functionality.
When Should You Replace Your Windshield Instead of Resealing?
If there are cracks or chips in the windshield, especially those longer than 6 inches, replacing the windshield is the best choice for maximum safety. For example, if you have a long crack across the driver's line of sight or a large chip in the center of the glass, a full replacement restores the windshield's strength and ensures its reliability. Cracks can spread quickly and are sensitive to temperature changes, road vibrations, or even minor impacts, making replacement the most effective solution.
If you notice a crack or chip in your windshield, addressing it promptly is a smart approach. Many auto glass repair shops offer free estimates or inspections. If the damage is minor, they may be able to repair it, but if it's more extensive, replacing the windshield ensures the highest level of safety and the best protection for you and your passengers.
When Resealing a Windshield is a Good Option
Resealing a windshield can be a great solution when the problem lies with the sealant rather than the glass. If you notice issues like water leaks, wind noise, or edge deterioration without significant glass damage, resealing can restore the windshield's performance and prevent further complications. Resealing is a cost-effective and quick fix, usually completed in a few hours, and is much more affordable than a full windshield replacement. However, if your windshield has cracks or chips that compromise its structural integrity, replacement is the safer option. Always consult with an expert to assess the condition of your windshield and ensure you're making the best decision for your safety and the longevity of your vehicle.
