Windshield Chip Repair and Long Crack Repair Services

Windshield repair is an effective and affordable alternative to replacing a windshield. Windshield repair is the process of repairing a windshield that has been cracked or chipped by rocks or debris. Windshields can be repaired by removing the air and crushed glass and injecting an acrylic-based resin into the crack or chip. If done correctly with professional-grade resins and equipment, the crack or chip will restore the structural integrity of the glass. Guardian Restoration Systems uses the best resin in the industry, making glass repairs up to 152% stronger than brand-new glass.

Our windshield repair process usually takes less than 30 minutes but can take up to an hour to complete.

Our auto glass repair customers appreciate the convenience of our free mobile service, which comes to your home, office, or any safe location.

Once we repaired a rock chip on this Tesla X Plaid, we protected the windshield, roof, and back hatch glass. First, we polished the glass to remove any hard water stains, debris, or mild defects. Then our proprietary glass cleaner is used to clean and remove excess compounds, polishes, wax, oils, and other contaminants. Finally, we applied our Nano-Shield quartz coating to the glass. This process not only gives your glass a beautiful deep reflection but also protects it from small debris, preventing rock chips and cracks. 




Hard to see at night? We can help! Call the highest-rated Headlight Restoration company in the Bay Area.

Professional Headlight Restorations are an instant safety upgrade for any vehicle.

Headlights are one of the most neglected parts of a vehicle. If your lights are hazy or oxidized, you can lose as much as 80% of your light output. Having Guardian Restoration Systems restore your lights gives any vehicle an updated look and creates a safer driving experience that will last for years.

Over time, sunlight, car washes, and weather can affect your headlights, making them yellowed, cloudy, peeling, or even cracked. If you had tried to restore them yourself but ended up with headlights that look worse than before you started, don’t worry. It’s not your fault. Youtube and other do-it-yourself myths make it look easy to restore lights. Unfortunately, sometimes things can go wrong very quickly. With over 4000 sets of headlights successfully restored, there is an excellent chance we can still save yours. Send us a picture and let us know what was done to the lights to determine what it would take to avoid replacing them.
