Windshield Crack Repairs

One Inch to Twenty-Four Inches

Were you aware that fixing windshield cracks, even those stretching up to twenty-four inches, can be a cost-effective alternative to replacing your windshield? Unfortunately, a considerable amount of misinformation is circulating, particularly from replacement shops aiming to steer you toward replacing your entire windshield. Falsehoods, such as the impossibility of repairing cracks reaching the edge of the glass or the idea that repairs compromise the structural integrity of the glass, are spread by these unethical shops prioritizing their profits over customer-friendly options. Our repairs not only stop the crack from spreading but also have a strength rating up to 152% of that of a new windshield. We guarantee it!

Windshield Crack Repair

There are numerous myths surrounding windshield crack repair. Safety is always the priority for our customers. Here are some of the misconceptions about repairs

  • "Crack repairs are not safe." This is 100% false. A crack repair performed by Guardian has a strength rating of up to 152% stronger than new glass. A repair restores the structural integrity of the glass completely.

  • "You cannot repair a crack longer than 6 inches." At Guardian, we possess the skills, equipment, and expertise to repair cracks as long as twenty-four inches in length.

  • "A crack repair cannot be done if the crack touches an edge." False. The most common repair is an edge crack where the damage extends from one edge of the glass to approximately fourteen inches toward the middle. As long as the damage does not reach two edges of the glass, a repair is a great alternative to replacing the glass.

  • "A crack repair will still be visible once repaired." True. Crack repairs are intended to restore the structural integrity of the glass and are not purely cosmetic. Although crack repairs typically improve the appearance by 70 to 90%, they may still be visible from certain angles. This is because the resin reflects light differently from various angles, altering the repair's appearance depending on the view. Several factors influence how a repair looks once completed, including the age of the crack, dirt, debris, length, and the type of crack. If having a scar would bother or distract you while driving, a replacement may be a better option.

Should I repair or replace my windshield?

Your choice depends on your priorities. If you don't mind a visible scar, a repair is likely the best option. Repairs are permanent and will fully restore the structural integrity of the glass and the repaired area can be up to 152% stronger than the original glass. Repairs are especially recommended if you still have the factory windshield.

However, a replacement may be the best option if you don't want to see a scar or if the damage is directly in the driver's line of sight. Please note that we do not recommend, endorse, or work with any replacement shops.


How do I know if my damage can be repaired?

Determining if the damage on your glass is repairable can be a bit tricky. The first thing you should do is text us a photo of the damage. You can reach Jason directly at 650-642-5400. Sometimes getting a good photo of the damage can be difficult due to lighting or the location of the crack. Here are a few key photos we need to see clearly:

  • The impact point where the rock hit the glass, causing the crack.

  • The full length of the crack.

Please do not send a photo of just a small portion of the crack. We need to see how extensive the damage is.

We also need an accurate measurement of the damage. When measuring a windshield crack, it is important to measure around any curves and measure to the edge of the glass if needed to get an accurate length. If the crack curves but you measure from end to end in a straight line, the measurement will be inaccurate. Below are a few pictures to help you get an accurate length.

Thinking of using a DIY kit to repair your windshield crack? Plan on replacing your glass!

Using a DIY windshield repair kit can be risky compared to having a professional do the repair. These kits often come with subpar materials and lack the precision tools needed for a proper fix, potentially leading to inadequate repairs. A poorly executed DIY repair can worsen the damage, compromising the structural integrity of the windshield and reducing its ability to protect occupants in the event of an accident. Professionals, on the other hand, have the expertise, experience, and high-quality materials to ensure a safe and effective repair, preserving the strength and clarity of your windshield.

Pre-Repair Tips

Although repairing the damage is the only way to prevent it from growing, here are a few things that may keep your rock chip or windshield crack from expanding before we can fix it.


Do not park on a steep driveway or hill

Parking on an incline may lead to the damage spreading before it can be repaired.

Do not use your defroster or air conditioner on the glass. 
If you rapidly heat or cool your windshield, it may cause the damage to spread.
Do not wash the car or get the glass wet. 
Refrain from washing or exposing the glass to rain to prevent further damage. Sealing the crack with packing tape is recommended if the glass is exposed to rainy weather.
Do not add anything to the damage.
Do not apply any substances to the damage. The only effective way to strengthen or prevent the spread of a chip or crack is to have it professionally repaired. The use of super glue, nail polish, or any other adhesive will hinder the success of a proper repair.


Cover the damage with packing tape or something similar. 

Use packing tape to cover the damage and keep it dry and clean. Although this won't prevent the damage from expanding, it will increase the likelihood of the repair looking its best.
