Windshield Repair: When a Chip Can Be Saved

A repair may be the ideal option when:

  • The chip is small and has no spreading cracks.
  • The damage is not in the driver’s direct line of sight.
  • The structural integrity of the glass is still intact.

If repairable, we inject a specialized resin into the damaged area, restoring clarity and preventing the issue from spreading.


A chipped windshield doesn’t always need full replacement, and we believe in repairing the glass whenever it is safe to do so. Our technicians evaluate the size, depth, and placement of each chip to determine whether repair is possible.

When Windshield Repair Is Safe and Effective

Transparency You Can Trust

At AJ’s Auto Glass Inc., we provide honest assessments. If a repair isn’t the safest option, we’ll explain why and guide you toward replacement instead—always prioritizing your safety and long-term value.

Windshield Replacement for Full Safety & Clear Visibility


When damage goes beyond what a repair can safely handle, full windshield replacement becomes necessary. Because your windshield is part of the vehicle’s structural support and works with safety systems like airbags and advanced cameras, accuracy matters.

Our Windshield Replacement Standards

Every replacement at AJ’s Auto Glass Inc. includes:

  • OEM-grade or OEM-equivalent glass
  • Precision alignment technology
  • Industry-approved urethane adhesives
  • Proper curing time to ensure maximum bond strength
  • A lifetime warranty against water and air leakage

We also ensure the interior is cleaned after replacement, removing any debris or glass dust before returning the vehicle to you.

Credit Toward Replacement

If your windshield chip was previously repaired by us and later spreads into a crack, the chip repair cost is applied toward the full replacement—part of our commitment to fairness and customer satisfaction.

Side, Door, Vent & Quarter Glass Replacement


Unlike windshields, side windows and rear-door glass cannot be repaired when broken—they must be fully replaced. These pieces often shatter into small fragments, creating both a safety hazard and a structural concern.

Our Process for Side Glass Replacement

  • We remove all shattered glass from the seats, floor, door panels, and surrounding areas.
  • We replace the damaged glass with OEM-level materials.
  • We test window alignment and function.
  • We ensure no rattling, gaps, or debris remain.

This service is especially helpful for customers who require fast, reliable replacement after vandalism, weather damage, or accidents.

Back Glass Repair & Replacement


Back glass fractures differently than windshields, and while small chips can sometimes be repaired, replacement is often necessary.

What Makes Back Glass Unique?

Back windows often include defroster lines, antennas, or sensors that require specialized installation. Our technicians handle these components with care to ensure everything functions correctly after replacement.

Just like with windshields, our back glass replacements include a lifetime warranty on air and water leaks.

Sunroof Glass Repair & Replacement


Sunroof and panoramic roof glass require precise handling to maintain the vehicle’s structural integrity and weatherproofing.

Our Sunroof Expertise Includes:

  • Movable sunroof panel replacement
  • Panoramic roof glass replacement
  • Resealing and leak correction
  • Inspection of tracks, motors, and surrounding components

We use toughened glass equivalent to OEM materials, ensuring durability and reliability.

Our Process: From First Call to Final Inspection


Step 1: Damage Assessment & Clear Explanation

We identify whether repair or replacement is the safest option and walk you through the process.

Step 2: Expert Repair or Install

Using high-grade materials and best practices, we complete the work efficiently and accurately.

Step 3: ADAS Calibration (If Needed)

Vehicles equipped with cameras or sensors require recalibration after windshield replacement—we handle this on-site so you don’t need multiple appointments.

Step 4: Clean-Up & Inspection

We ensure your vehicle is clean, your glass is flawless, and your safety systems are functioning properly.
