How to Fix a Cracked Windshield at Home
Fixing a cracked windshield at home can save you money and time. Before you start, it is important to understand the type and size of the crack. Small cracks and chips are easier to repair than large or complex cracks.
Understanding Different Types of Windshield Cracks
Knowing the type of crack can help you decide if a DIY repair is possible. Common types include chip, stress crack, bullseye, and starburst. Each type affects the repair process differently.
- Chip: Small pieces of glass broken off, usually less than an inch.
- Stress crack: Long, hairline cracks caused by temperature changes or stress.
- Bullseye: Circular cracks with a central point of impact.
- Starburst: Crack pattern radiating from the point of impact, resembling a star.
Tools and Materials Needed for DIY Repair
Gathering the right tools ensures a successful repair. Here is a list of essential items:
- Windshield repair kit: Usually includes resin, applicator, and curing strips.
- Glass cleaner: To clean the area before repair.
- Razor blade or scraper: To remove excess resin.
- Cloth or paper towels: For cleaning and drying.
- UV light or sunlight: To cure the resin.
Step-by-Step Guide to Fix a Cracked Windshield at Home
Step 1: Clean the Area
Begin by thoroughly cleaning the cracked area with a glass cleaner. Remove any dirt, dust, or debris that could interfere with the repair. Make sure the crack is dry before proceeding.
Step 2: Prepare the Repair Kit
Read the instructions that come with your windshield repair kit. Typically, you will need to attach a pedestal or template to the windshield to hold the resin applicator firmly.
Step 3: Apply the Resin
Place the resin vial into the applicator. Carefully position the applicator over the crack or chip, ensuring it is centered. Squeeze the resin into the crack slowly until it is filled or the resin starts to seep out.
Step 4: Cure the Resin
Use a UV light if included or place the windshield in direct sunlight. Curing usually takes between 5 and 15 minutes. This hardens the resin and strengthens the repair.
Step 5: Remove Excess Resin
Once cured, use a razor blade or scraper to gently remove any excess resin from the surface. Be careful not to scratch the glass. Wipe the area with a clean cloth.
Additional Tips for a Better Repair
To maximize the effectiveness of your DIY repair, consider these tips:
- Work in a clean, dust-free environment: Dust can get trapped in the resin and weaken the repair.
- Do not repair if the crack is larger than a dollar bill: Larger cracks often require professional fixing or replacement.
- Avoid washing the car or exposing it to rain: Moisture can interfere with the resin curing process.
- Handle the resin with care: Resin can stain or damage surfaces if spilled.
When to Seek Professional Help
While small cracks can be fixed at home, some situations require professional repair. Large or multiple cracks, cracks in the driver’s line of sight, or damage that affects the structural integrity of the windshield should be inspected by a professional.
If the crack is spreading or expanding over time after your DIY attempt, it’s best to contact a windshield specialist to prevent safety risks.
Precautions and Safety Tips
Working with glass and resin involves some risks. Always wear gloves to prevent cuts and stains. Use eye protection if you’re working with tools or applying resin. Ensure your workspace is well-ventilated, especially if using chemical adhesives.

Frequently Asked Questions
What steps can I take to temporarily prevent a crack from spreading in my windshield?
If you notice a crack forming, you can apply clear tape or a repair patch over the area to keep dirt and moisture out. This simple step helps slow down the crack’s growth until you can get professional repair or replacement. Avoid washing the car or exposing it to extreme temperature changes, as these actions can cause the crack to expand further.
Is there a way to fix a small crack without professional help?
For small cracks or chips, you can use a DIY windshield repair kit available at auto parts stores. These kits include resin that hardens to fill the crack and restore part of the windshield’s strength. Carefully follow the instructions provided with the kit for best results, but remember that larger or more complex cracks will likely require professional attention.
How can I safely handle a crack that is near the edges of my windshield?
Cracks close to the edges of the windshield tend to be more unstable and may compromise the vehicle’s safety. Avoid driving with such cracks, and visit a professional repair technician as soon as possible. If you need to drive temporarily, minimize stress on the windshield by avoiding rough roads and driving gently to prevent the crack from worsening.
Are there any risks associated with DIY windshield repair methods?
Yes, attempting to fix a crack without proper expertise can sometimes make the damage worse or lead to ineffective repairs. Poorly filled cracks may reappear or impair visibility. If the crack is large, in the driver’s line of sight, or if you’re unsure about the repair process, seeking professional help ensures the job is done correctly and safely.
Final Thoughts
To fix a cracked windshield at home, start by cleaning the area around the crack thoroughly. Use a plastic syringe or a clear adhesive resin to fill the crack with a clear resin. Apply the resin evenly and remove excess with a razor blade.
Next, let the resin cure in a dust-free environment for several hours. This strengthens the glass and prevents the crack from spreading further.
In conclusion, knowing how to fix a cracked windshield at home helps save time and money. Proper repairs restore the windshield’s integrity and improve safety.
