What to Do about a Small Crack in Windshield?
Assessing the Situation
A small crack in the windshield can be a frustrating and worrisome issue for many car owners. It’s essential to assess the situation carefully to determine the best course of action. Here are some factors to consider:
Location and size of the crack: A small crack located in the middle of the windshield is more concerning than one near the edge. A crack that’s less than an inch long is generally less severe than one that’s longer.
Depth of the crack: A crack that’s only superficial, meaning it doesn’t penetrate the windshield’s inner layer, is less severe than one that’s deeper.
Weather conditions: Extreme temperatures, direct sunlight, or heavy rain can exacerbate the crack.
Age and type of windshield: Modern windshields made of laminated glass are more resistant to cracks than older windshields or those made of tempered glass.
Driving conditions: If the crack is located in a critical area, such as near the driver’s line of sight, it may be more problematic for driving.
Do-It-Yourself Repairs
If the crack is small and superficial, you might be able to repair it yourself. Here are some steps to follow:
- Choose a windshield repair kit: These kits usually include a resin and a special tool to inject the resin into the crack.
- Clean the area around the crack: Remove any dirt, debris, or old adhesive from the area.
- Apply the resin: Use the special tool to inject the resin into the crack, making sure to fill the entire length.
- Cure the resin: Follow the manufacturer’s instructions for curing the resin, usually under a UV light.
- Inspect the repair: Check the repair to ensure the resin has fully cured and the crack is no longer visible.
However, if the crack is large, deep, or in a critical area, it’s best to seek professional help. DIY repairs can sometimes make the crack worse or even cause further damage to the windshield.
Professional Windshield Repair
If you’re not comfortable with DIY repairs or if the crack is more severe, it’s best to seek the help of a professional windshield repair technician. Here are some benefits of professional repairs:
- Expertise: Professionals have the knowledge and experience to repair windshields safely and effectively.

- Insurance coverage: If you have comprehensive insurance, your insurance company may cover the cost of the repair.
When choosing a professional repair shop, make sure to research their reputation, read reviews, and ask for referrals from friends or family members.
Windshield Replacement
In some cases, the crack may be too severe to repair, and windshield replacement may be the best option. Here are some scenarios where replacement is necessary:
- Large cracks: If the crack is longer than an inch or in a critical area, replacement is usually the best option.
- Deep cracks: If the crack has penetrated the windshield’s inner layer, replacement is usually necessary.
- Multiple cracks: If there are multiple cracks in the windshield, replacement may be the best option.
- Age and type of windshield: If the windshield is old or made of tempered glass, replacement may be necessary.
When replacing the windshield, make sure to choose a reputable and experienced auto glass shop. They will assess the situation, provide a quote, and install a new windshield that meets or exceeds your vehicle’s manufacturer specifications.
