A small windshield chip may not seem like a big deal, but if left untreated, it can quickly turn into a large crack that requires a full replacement. Fixing a small chip yourself can save time and money, and with the right tools and technique, you can restore the strength and clarity of your windshield.

Before attempting a DIY windshield repair, it is important to assess the damage and use the right materials to ensure the best results.

When Can You Repair a Windshield Chip Yourself

Not all chips can be repaired using a DIY kit. Some damage is too severe or located in critical areas, requiring professional repair or full windshield replacement.

Chips That Can Be Fixed with a DIY Kit

• Small chips less than the size of a quarter

• Star-shaped, bullseye, or minor surface chips

• Damage not in the driver’s direct line of sight

• Chips that have not developed into long cracks

Chips That Require Professional Repair or Replacement

• Cracks longer than three inches

• Multiple chips close together

• Damage near the edges of the windshield

• Chips filled with dirt, moisture, or debris

• Damage obstructing the driver's vision

If your windshield has large cracks or multiple chips, a DIY repair may not be effective, and professional repair or replacement is the safest option.

What You Need to Fix a Windshield Chip

A windshield repair kit can be purchased at most auto parts stores or online. These kits contain resin and application tools designed to fill in the chip and prevent further cracking.

Basic Tools and Materials Needed

• Windshield repair kit (containing resin, applicator, curing strips, and razor blade)

• Glass cleaner and microfiber cloth

• Safety gloves and protective eyewear

• Direct sunlight or a UV light for curing the resin

Step-by-Step Guide to Fixing a Small Windshield Chip

Step 1: Clean the Windshield

• Use a glass cleaner and microfiber cloth to remove dust, dirt, and debris from the windshield.

• Avoid using ammonia-based cleaners, as they can weaken the resin bond.

• Make sure the windshield is completely dry before starting the repair.

Step 2: Position the Applicator Over the Chip

• Most repair kits include a suction applicator that attaches directly over the chip.

• Center the applicator over the damaged area and press it firmly against the glass.

Step 3: Apply the Repair Resin

• Follow the instructions on your windshield repair kit and insert the resin into the applicator.

• Use the plunger or syringe to inject the resin into the chip, filling the damaged area completely.

• Let the resin sit for five to ten minutes to allow it to settle and bond with the glass.

Step 4: Remove Air Bubbles

• Use the plunger or pressure tool included in the kit to force out any trapped air bubbles from the resin.

• Air bubbles can weaken the repair, so ensure the resin spreads evenly inside the chip.

Step 5: Apply Curing Strip and Let the Resin Harden

• Place a curing strip or clear plastic film over the resin to hold it in place while it dries.

• Park the vehicle in direct sunlight for 15 to 30 minutes, or use a UV light to speed up the curing process.

Step 6: Remove Excess Resin and Polish the Windshield

• Once the resin is fully cured, use a razor blade to carefully scrape away excess material.

• Clean the area with glass cleaner and a microfiber cloth to restore visibility.

How Effective Are DIY Windshield Chip Repairs

DIY windshield repairs can prevent chips from spreading and improve visibility, but they may not completely restore the glass to its original clarity.

Pros of DIY Windshield Repair

• Saves money compared to professional repairs or replacements.

• Quick and convenient, taking only 30 to 60 minutes.

• Prevents small chips from turning into larger cracks.

Cons of DIY Windshield Repair

• Not as strong as professional repairs, since professionals use higher-quality resins and specialized tools.

• May not fully restore clarity, especially if the chip was large or had dirt inside.

• Risk of improper sealing, leading to the crack spreading over time.

When to Call a Professional

Even if you successfully fix a chip with a DIY kit, there are situations where professional repair or replacement is the better choice.

• The chip is in the driver’s line of sight, affecting visibility.

• The damage is near the edges of the windshield, where structural integrity is crucial.

• The chip is too large or deep for a DIY repair kit to fix properly.

• The windshield has multiple chips or cracks, making it weaker overall.

Final Thoughts: Is DIY Windshield Repair Worth It

Fixing a small windshield chip yourself can be an affordable and effective way to prevent further damage, but it is important to know when professional repair or replacement is needed. Using a high-quality DIY repair kit, following the correct application process, and ensuring the chip is properly sealed can help extend the life of your windshield.
