What is automotive glass refinishing?

Automotive glass refinishing refers to the process of restoring the appearance and functionality of vehicle glass, such as windshields, and windows. This restoration can involve repairing minor damage like scratches, chips, or cracks, as well as addressing more significant issues like deep scratches or etched graffiti. Automotive glass refinishing may also encompass techniques to improve clarity, remove imperfections, and enhance the overall aesthetics of the glass surface.

  • You charge more than most for a repair. Why should I pay a little more?
    When it comes to rock chip repairs, there are always companies offering lower prices. However, there are three compelling reasons why you should choose Guardian over competitors. Firstly, we are certified to repair long cracks up to 14 inches. This means that if the rock chip expands during the repair process, we have the expertise to complete the job and salvage your glass. In contrast, if you opt for a company that cannot fix larger cracks, they may either abandon the repair, leaving you with a cracked windshield that requires replacement or persuade you to replace the windshield altogether. Secondly, we employ the best resins, equipment, and training in the industry to provide superior repair quality. Our repairs are stronger than new glass, and although there may be a faint scar, our repairs look better than those of any other company. Lastly, our customer service is unparalleled in the industry. Once you've used Guardian Windshield Repair, you'll never need another glass company again.
  • How do I know if my windshield can be repaired?
    Rock chips that are under an inch in length or diameter, there is a high likelihood of successful repair - up to 99%. However, if the damage has expanded, please send us a photo of the affected area via text at 650-671-0247, and we can assess whether the glass can still be restored. It's worth noting that we do not collaborate with any replacement shops as we cannot ensure the quality of their work. Therefore, if replacement becomes the better option, we suggest seeking out a reputable replacement provider.
  • Will the chip or crack still be visible after the repair?
    The primary objective of any windshield repair is to salvage the glass and prevent the need for a costly replacement. While a repair can greatly enhance the appearance of the damaged area, it's essential to note that it cannot be entirely concealed. However, you can expect the repair to look 70% to 90% better once completed. With over 12,000 windshields successfully restored, we have a wealth of expertise in repairing glass. Our team of professionals is committed to providing the best repair service possible, and we take pride in offering repairs that look superior to those of any other industry competitor.
  • Will the repair change the structural integrity of the glass?
    At Guardian Windshield Repair, we utilize top-of-the-line resins and equipment available worldwide to deliver the highest quality repairs possible. Our repair work has a structural strength that can be up to 132% of that of brand new glass. It's worth noting that if a rock chip is repaired correctly, it won't compromise the structural integrity of the glass in any way. Our expert technicians take great care to ensure that the repair is completed to the highest standard, leaving your windshield as strong and secure as it was before the damage occurred.
  • Is the repair guaranteed?
    Certainly! We stand behind all of our repair work with a lifetime guarantee. While it's uncommon, if the damage ever expands or alters, please notify us, and we will reattempt the repair at no additional cost. In the event that we are unable to salvage the glass for any reason, we will refund any payment made for the attempted repair.
  • Can you service large recreational vehicles?
    Absolutely! No matter the size of your vehicle, we're equipped to handle repairs and glass coatings. Whether it's a small car or a large coach, RV, or truck, we're up to the task. If you have a larger vehicle, kindly inform us in advance, so we can make the necessary preparations to ensure we provide the best service possible.
  • What are some of the pros and cons of a rock chip repair?
    Advantages: Preserves factory seal: Repairing the glass maintains the factory windshield and seal, which prevents potential issues like wind noise, rust, stress cracks, and water leaks that can arise from replacing the windshield and tampering with the factory seal. Calibration not needed: Since a repair doesn't involve replacing the windshield, there's no need for recalibrating sensors like ADAS, which could be quite costly. Safe: If done correctly by a certified technician, a crack repair doesn't affect the structural integrity of the windshield. Cost-effective: Repairs typically cost much less than a windshield replacement. Convenient: Repairing a crack can be done on-site, usually within an hour, making it an easy and quick solution. Stops further damage: A repair prevents the damage from spreading, and it will last for the windshield's lifetime. Disadvantages: Scar: A repair won't entirely hide the damage, and although it will be fully restored, factors like the age, type, and location of the crack, as well as dirt or debris, moisture, and other factors, can affect the repair's appearance. You can expect the repair to look 70% to 80% better visually, but if the crack is in a noticeable spot, a replacement may be a better option.
  • Do you have a shop or are you mobile?
    Our services are entirely mobile, and we can bring them to you wherever you are. Whether it's at your home, workplace, or any other safe location of your choosing, we're equipped to provide our services on-site for your convenience
  • Are you licensed and insured?
    We are fully licensed, bonded, and insured, providing you with complete peace of mind when we handle your vehicle. We treat every vehicle with the utmost care and attention to detail, as if it were our own, ensuring that it's in good hands throughout the service process.
  • Do you offer replacement glass?
    Our area of expertise is focused on preserving your windshield and repairing it to the highest possible standard. We do not offer any replacement glass services, as we believe in providing specialized repair services rather than general solutions. Additionally, we do not collaborate with or endorse any replacement glass shops since we cannot guarantee the quality of their work, making it challenging to control the outcome.
