Finding out that your car's windshield is chipped or cracked can be the beginning of a headache. To find out if your windshield can be covered by insurance Click Here.  Even though it’s recommended that you repair the damage as soon as possible, minor windshield repair isn’t too complicated, especially if you inform yourself on the steps you should take to do so. Learn how to repair a cracked windshield in the most budget-friendly way.

Repair or Replace?

Depending on the severity of damage in your car’s cracked windshield, you could take one of two routes. The industry standard is that if a windshield crack can be covered with a dollar bill, or measures less than 3 inches, it’s possible to simply repair the windshield without having to replace the entire windshield. On the other hand, windshield replacement is recommended if there are 3 or more cracks on the glass, or if the damage is located directly in front of the driver's line of sight or on the windshield's edge.

Undoubtedly, having to fully replace a car’s windshield is much more expensive than a simple windshield repair. One source reports that the cost of replacing a windshield is generally within the range of $100 to $400. On the other hand, the windshield repair prices can vary a lot, especially if you decide to take your car to a shop. In fact, some workshops charge between $50 and $60 to repair chips or cracks. Keep in mind, the cheapest option is to buy a $10 or $15 do-it-yourself windshield repair kit at an auto parts store or through sites such as Amazon, so you can do the repairs at home while saving money at the same time.

If you choose not to go to a shop and go the do-it yourself route, follow these steps on how to repair a cracked windshield at home without having to go to a professional. (Remember, the fact that you decide to repair it yourself means that the repair quality of a shop isn’t guaranteed.)

Repair Procedure Steps

There’s several windshield repair kits on the market, but one of the most common products is the RainX Fix a Windshield kit, which costs $12.50 on Amazon. We decided to base the following windshield repair steps on this product since it’s widely accessible to many car owners.

Step # 1: Prepare the Affected Area

Try to park the vehicle in a shaded area where the car won’t be exposed to the sun directly. We don’t want the liquid you are going to apply to dry prematurely.

Then, use a razor blade and scrape it against the surface of the glass in the affected area to remove unwanted glass particles and dirt. You can even use the edge of the blade to remove the smaller particles. Any piece of dust or dirt in the crack can prevent the kit from achieving the best results.

Step # 2: Place the Mount

All windshield repair kits have different tools, and the RainX kit comes with a mount and suction cups to attach it to the windshield.

Just mount the center of this piece directly on the crack and press it down, so that the suction cups are stuck firmly onto the glass.

Step # 3: Screw in Resin Tool

With the mount directly over the damaged area, screw the white repair tube into the center of the suction cup tool. Do it slowly, and make sure that only one of the white tubes (the widest one) is screwed into the center.

The correct alignment of the tools in the kit is essential for windshield crack repair, so we recommend checking the position of the threaded tube. You can check the tube alignment from inside the car. The circular rubber area on the edge of the tube should be hitting directly around the crack in your windshield.

Step # 4: Add 6 Drops of Resin

Resin is the liquid that comes in a small plastic container with the kit, and it’s the substance that will ultimately harden and replace the broken pieces of glass. Uncover the resin, place the resin tip over the white tube you aligned in the last step, and squeeze gently, until 6 drops of resin come out.

Step # 5: Put the Plunger in the Resin Tool

Immediately after adding the resin drops, insert the center plunger (the narrowest white tube inside the wide white tube) and press down. The plunger will force the resin into the affected area.

It is important to make sure that the air bubbles in the resin are kept to a minimum. That's why we recommend tightening the central plunger slowly, as well as gently tapping the glass around the crack. This way, some air escapes from the surface.

Step # 6: Place Plastic Strip

After a few minutes, if you’re satisfied with the results, you can unscrew the resin tool from the support piece and remove all the parts that were attached to the windshield.

Now, for the final touch, just add an additional drop of resin directly into the affected area and cover it with one of the plastic strips that come with the kit. Next, park the car in a place where it’s exposed under the sun, and wait 10 minutes until the resin dries.

When the 10 minutes have passed, just peel the plastic strip, and use your razor blade to scrape and remove the excess dry resin around the surface.
