2021 Guide

Not sure what a windshield repair is? No problem, we’re here to help.

If you’ve driven a vehicle within the past 50 years or so, you’ve probably heard a rock hit your windshield at least one point in time. Sometimes, when a rock or road debris hits your windshield hard enough, it can cause the glass to chip or crack. This is called a “rock chip” or “stone chip”. In most cases, these chips can be repaired to help prevent the damaged area from spreading out into long cracks. This is called a “windshield repair”. A windshield repair will help save you from the cost of a windshield replacement in the future. 

To help you out, in this guide we will explain what a windshield repair is, how it works, why you need one and what a windshield repair can do for you.

What is a Windshield Repair?

A windshield repair is the process of removing trapped air and injecting acrylic resin into laminated glass to prevent the damaged area from spreading into cracks. Many types of stone damage can be successfully repaired. Whether the windshield can be repaired or not depends upon the size, type, depth and the location of the damage. Repairing your windshield chips before they spread out will save you the cost of a windshield replacement in the future. 

Windshield repairs are an effective way to save the life of your vehicle’s windshield. Your windshield holds a lot of structural integrity of your vehicle, so it’s important to keep your windshield in excellent shape. Most auto glass shops and windshield repair technicians can repair cracks up to 2 inches in diameter and 8 inches in length (depending on local laws, and the type, depth and location of the damage). If you don’t repair your windshield chip in time, it will eventually spread into a long crack or multiple cracks thus forcing you to replace your windshield.

Why do I need a Windshield Repair?

The reason why you need a windshield repair is fairly simple. You have a rock chip or stone chip in your windshield and you want to fix it before it gets any worse. Some people don’t think a chip will spread out into a crack, but 99% of all windshield cracks will start from a chip. It is important to repair the chip as soon as possible in order to save yourself a costly windshield replacement in the future. Some people will get a windshield repair because they don’t like the look of the damage. While this does help, the main reason you need a windshield repair is so you can prevent the damaged area from getting any bigger.

While the benefits of windshield repair are just starting to become popular in the past 30 years or so, it wasn’t long ago that you could not repair your windshield at all. You had no other option but to replace your windshield. As technology has advanced, so has the windshield repair industry. More and more people are now aware that they can repair rock chips and small cracks before they spread out. Windshield repair has become a safer and more environmentally-friendly way to prolong the life of your windshield.

What does a Windshield Repair do and how does it work?

Simply put, a windshield repair stops the damaged area in your windshield from spreading into a long crack or multiple cracks. 

Windshield repairs work by removing the trapped air from in between the plastic laminate and the first layer of glass. Then an acrylic resin is injected to replace the trapped air. The resin is then cured from UV rays either from the sun or a strong UV light. Once cured, the excess resin is scraped off and the pit area is cleaned and buffed out. 

Most auto glass technicians will inspect the damaged area and remove any surface debris using a specialized tool and/or drill. This is done to access the centre of the break.

Next, a specialized windshield repair bridge is mounted over top of the damaged area. This machine uses a vacuum to remove the trapped air inside the break. This prevents air bubbles and prepares the break for the resin. Then a high bond strength acrylic resin is injected into the damaged area through an injector pin. This pin will gently push resin inside the break.

Vacuum and pressure cycles are then alternated to remove the air and push in the resin. After the rock chip has been filled, it is covered with a pit resin and a finishing film is applied. The break will then be exposed to a specialized ultraviolet (UV) lamp. The lamp will cure the resin outside of the break and the glass on the inside of the rock chip.

Once the resin is done curing, the excess resin will be removed by using a straight edge razor blade. The pit will then be filled and the surface of the impact point should be smooth with the rest of your windshield. After the repair, the visibility of the rock chip should improve anywhere from 70% to 90%, depending on the type of break, impact point and the age of the rock chip.

Windshield Repair FAQ

What is the difference between a windshield repair and a replacement?

Some people assume that a windshield repair is the same thing as a windshield replacement. We’re here to set the record straight. They are two very separate things.

A windshield repair does not require removing the windshield and it usually takes anywhere from 15 minutes to 60 minutes to complete. A windshield repair will cost anywhere from $20 to $100, depending on the number of chips, the size of the chip and who you use. It is a safer alternative to repair your windshield. A windshield repair consists of injecting resin into the damaged glass and once cured, restores the structural integrity of your windshield. In some cases, you may need to replace your windshield. 

A windshield replacement involves removing the currently damaged windshield and fitting a new piece of glass to your vehicle. After the windshield is removed, the auto glass technician will clean and prepare your vehicle and apply urethane to bond the new windshield to your vehicle’s frame. You will typically have to wait a few hours to 24 hours before driving. Most windshield replacements take anywhere from 45 minutes to 120 minutes, depending on the type of glass needed and the vehicle make and model. Windshield replacements vary in costs and it is best to contact a certified glass shop for a detailed quote for your vehicle.

How do I know if my windshield chip can be repaired?

If your windshield chip is smaller than 2 inches or your windshield crack is smaller than 8 inches, you may be able to repair it. View our article on different types of windshield damage here

How does the windshield repair process work?

A windshield repair involves cleaning and treating the damaged area with specially designed resins and tools. In most cases, the damage can be repaired in less than 60 minutes. You can use a D.I.Y. kit to repair a rock chip or you can seek a certified glass repair technician.

Can a long crack in my windshield be repaired?

This is a commonly asked question. Depending on the auto glass repair shop you use, some long cracks can be repaired. Any windshield cracks over 8 inches or in the driver’s field of vision should not be repaired and we recommend replacing your windshield.

Can the damage spread during a windshield repair?

Although it is rare, it is possible for the damage to spread further during the windshield repair. In some cases, the windshield damage can expand and will require a replacement. Sometimes the pressure, glass temperature and the amount of stress put on the damaged glass will cause the cracks to spread out. This is something to be aware of when having your chips or cracks repaired. It is always better to use a company with a windshield repair disclaimer and warranty, to provide you with some peace of mind.

Will the rock chip be invisible after the repair?

Unfortunately, no. A windshield chip repair is used to prevent the damaged area from expanding and requiring a replacement. This procedure is done to restore the structural integrity of the glass. While all chips and cracks are different, most successful repairs will improve visually and leave a slight blemish where the impact point was. In most cases, you should expect the cosmetic appearance of the repair to improve when compared to the damage prior to the repair. It is best to cover a new rock chip with tape immediately. This will help prevent dirt and moisture from entering the impact point. This can also help with the visual appearances after a successful windshield repair.

How long will it take to repair my windshield?

Most windshield chip repairs will take anywhere from 15 minutes to 60 minutes to complete. Most windshield crack repairs will take anywhere from 30 minutes to 120 minutes to complete. These repair times all depend on the experience of the glass repair technician, the tools used, the size, the age and the location of the chip or crack. In most cases, a windshield repair will take a lot less time than to replace your windshield. Save yourself some more time by opting for a repair, whenever possible.

How important is it to repair my windshield?

In short, it is extremely important to repair your windshield. A lot of people will assume that a small chip in a windshield is just a minor annoyance. Think again. It is important to take care of any windshield damage as soon as possible, to avoid the damaged area from spreading out and costing you a windshield replacement. A windshield repair will save you a lot of money, time and headaches in the future.

Where can I get a windshield repair?

Most windshield repairs are completed at an auto glass shop, mechanic shop or body shop. They can also be completed in your driveway at home or your parking spot at work via a professional mobile windshield repair service. The convenient thing about a windshield repair is that it does not require any large equipment or tools to operate.

How much does a windshield repair cost?

The best thing about a windshield repair is that it costs much less than a windshield replacement. In some cases, your insurance company might cover the cost of a repair as it saves them more money in the long run. A typical rock chip repair can cost anywhere from $20 to $80 depending on the size and location of the chip. A windshield crack repair can cost anywhere from $75 to $200 depending on the size of the crack and the location it originates from. These prices will vary depending on which company you use and where you live. It is best to base your decision on quality and service instead of price. Remember, you get what you pay for!
