Assessing and Preparing for the Repair: Understanding the Cracked Windshield
Evaluating the Extent of the Damage
A cracked windshield can be a frustrating and potentially hazardous issue, especially if left untreated. Before attempting to seal a cracked windshield, it’s essential to assess the extent of the damage. A thorough evaluation will help you determine the best course of action and decide whether a DIY repair or professional replacement is necessary.
When examining the cracked windshield, consider the following factors:
- Location: Is the crack in a visible or sensitive area, such as the driver’s line of sight or near the edges of the windshield?
- Size: How long is the crack, and is it growing or spreading?
- Depth: How deep is the crack, and are there any chips or pits surrounding it?
- Type: Is the crack a hairline fracture, a spider web pattern, or a sharp, jagged break?
For small, shallow cracks, a DIY repair kit may be sufficient. However, if the crack is long, deep, or in a sensitive area, it’s often best to consult a professional windshield repair technician.
Preparing the Windshield for Repair
Before attempting to seal a cracked windshield, make sure to prepare the area for repair. This includes:
- Removing any debris or dirt from the crack
- Cleaning the surrounding area with a gentle soap and water solution
- Applying a windshield repair kit’s special cleaning solution to the crack, if recommended
- Using a hair dryer or other heat source to warm the area, if necessary (check the repair kit’s instructions)
It’s also essential to ensure the windshield is clean and free of any obstructions, such as stickers, decals, or tint. This will help the repair kit adhere properly and ensure a smooth, even finish.

Frequently Asked Questions
What is a cracked windshield, and when should I seal it?
A cracked windshield is a damaged glass surface that compromises the structural integrity of your vehicle. You should seal a cracked windshield as soon as possible to prevent further damage, reduce safety risks, and maintain the overall condition of your vehicle. If the crack is small and doesn’t obstruct your view, you may be able to drive safely for a short period. However, if the crack is large, in a critical area (such as the driver’s line of sight), or spreading, it’s essential to have it sealed immediately. Regularly checking your windshield for cracks and addressing them promptly will help prevent more severe damage and costly repairs.
How does windshield sealant work?
Windshield sealant is a specialized adhesive designed to bond with the glass surface, filling in cracks and chips while creating a strong, durable seal. The sealant is typically applied in a liquid form and hardens over time, providing a waterproof and impact-resistant barrier. Some windshield sealants are available in DIY kits, which can be applied at home, while others require professional installation. The sealant works by penetrating the glass surface, filling in the crack, and then hardening to create a solid, impermeable bond.
Why should I seal a cracked windshield instead of replacing it?
Why should I seal a cracked windshield instead of replacing it?
Sealing a cracked windshield is often a more cost-effective and convenient option compared to replacing the entire windshield. Windshield replacement can be expensive, with prices ranging from $300 to $1,500 or more, depending on the vehicle and location. In contrast, a DIY windshield sealant kit can cost between $20 to $100, depending on the quality and size of the kit. Additionally, sealing a cracked windshield can be done in a matter of minutes, while windshield replacement typically requires a few hours or even days. Furthermore, sealing a cracked windshield can help preserve the original glass and maintain the vehicle’s factory seal, which can be lost during a replacement.
How do I start the windshield sealing process?
To start the windshield sealing process, you’ll need to prepare the area, clean the glass surface, and apply the sealant. Begin by cleaning the cracked area with a mild soap and water solution to remove any dirt or debris. Next, use a hair dryer or heat gun to warm the area, which will help the sealant spread more evenly. Apply a small amount of sealant to the cracked area, following the manufacturer’s instructions. Use a credit card or similar tool to spread the sealant evenly, ensuring it covers the entire crack. Allow the sealant to dry and harden according to the manufacturer’s instructions before driving your vehicle.
What if I’m not comfortable applying the sealant myself?
If you’re not comfortable applying the sealant yourself, it’s always best to seek the help of a professional. Auto glass technicians have the training and experience to apply windshield sealants correctly and efficiently. They will assess the damage, clean the area, and apply the sealant according to the manufacturer’s instructions. Additionally, professional installation often comes with a warranty, providing peace of mind and protection against any potential issues. If you’re unsure about the severity of the crack or the type of sealant needed, consult with a professional for guidance and assistance.
How much does it cost to seal a cracked windshield?
The cost of sealing a cracked windshield varies depending on the type and quality of the sealant, as well as the size of the crack. DIY kits can range from $20 to $100, while professional installation can cost anywhere from $50 to $200. The cost also depends on the location, with urban areas typically having higher prices than rural areas. Additionally, some auto glass shops may charge more for certain types of sealants or for complex repairs. It’s essential to research and compare prices before making a decision.
Which is better: DIY or professional windshield sealing?
The choice between DIY and professional windshield sealing depends on your level of comfort, the severity of the crack, and your budget. If you’re comfortable with the process and have a small, minor crack, a DIY kit may be a cost-effective solution. However, if the crack is large, complex, or in a critical area, or if you’re unsure about the process, it’s recommended to seek the help of a professional. Professional installation ensures a proper seal, warranty, and peace of mind, but it may come at a higher cost. (See: Change Windshield Wipers Lincoln Mkz)
Can I seal a windshield crack with regular glass adhesive?
Can I seal a windshield crack with regular glass adhesive?
No, it’s not recommended to use regular glass adhesive to seal a windshield crack. Windshield sealants are specifically designed for glass surfaces and have unique properties that allow them to bond with the glass, fill in cracks, and provide a strong, durable seal. Regular glass adhesive may not have the same level of adhesion, durability, or waterproofing, which can lead to a weak seal and potential safety risks. Additionally, regular glass adhesive may not be suitable for the high-temperature and high-impact conditions found in a windshield, which can cause it to fail prematurely. It’s essential to use a windshield sealant specifically designed for this purpose to ensure a safe and effective repair.
Will sealing a cracked windshield affect my vehicle’s warranty?
Sealing a cracked windshield may affect your vehicle’s warranty, depending on the manufacturer’s policies and the type of sealant used. Some manufacturers may consider a sealed windshield a valid repair, while others may view it as a non-manufacturer-approved repair. If you’re unsure about the impact on your warranty, consult with your vehicle’s manufacturer or dealer before proceeding with the repair. Additionally, using a high-quality windshield sealant that meets or exceeds the manufacturer’s standards can help minimize any potential impact on your warranty.
How long does a sealed windshield last?
The lifespan of a sealed windshield depends on various factors, including the type and quality of the sealant, the severity of the crack, and the environmental conditions. A properly applied windshield sealant can last for several years, often up to 5-10 years or more, depending on the manufacturer’s claims. However, it’s essential to regularly inspect the sealed area for any signs of degradation or cracking, and address any issues promptly to prevent further damage.
