Windshield repair or replacement? Compare cracks, visibility, and ADAS factors. Get expert guidance from Westgate Auto Glass today.
The Two-Dollar Coin Test
You can begin with a quick look at the damaged area before arranging service. Westgate uses a two-dollar coin as one general reference point when determining whether a chip may qualify for repair.
Ask yourself:
- Is the chip small enough to be covered by a two-dollar coin?
- Are any cracks extending from it less than three inches?
- Is the damage away from the outer edge of the windshield?
- Is it outside the driver's direct line of sight?
- Has the damage remained relatively localized?
These checks can give you an initial idea of the extent of the damage, but they are not a substitute for a professional assessment. Each situation is different, so having the glass professionally assessed can help determine the appropriate solution.
When A Repair Will Work
Not every windshield chip means the entire windshield needs to be replaced. Several conditions can indicate when a repair may be possible.
A repair may be suitable when:
- The chip is small enough to be covered by a two-dollar coin.
- Cracks have not spread extensively.
- A crack is less than three inches long.
- The damage is away from the outer edge.
- The driver's view is not significantly affected.
Size Is One Factor
If you are wondering when to repair a windshield crack, size is an important consideration, but it is not the only one.
Westgate's auto glass repair guidance states that repair is usually possible when the damage is smaller than a two-dollar coin, and a crack is less than three inches long. However, the position of the damage and its effect on visibility also need to be considered.
This means two areas of damage that appear similar in size may not necessarily require the same service.
Why Location Matters
The location of windshield damage can affect whether repair is appropriate.
Damage that is away from the outer edge and outside the driver's direct line of sight may be more suitable for repair. Damage that reaches the edge or significantly affects visibility may instead require replacement.
If you are asking, is my windshield chip repairable, looking at its size is only the starting point. The location and extent of the damage should also be assessed.
When You Need A Full Replacement
Sometimes windshield damage has progressed beyond what a repair can reasonably address. In these situations, replacing the windshield may be the appropriate option.
Several circumstances may indicate that windshield replacement is more appropriate, including extensive cracks, damage reaching the edge, multiple impact points that may weaken the glass, and significant visibility problems.
Long Cracks And Edge Damage
A small chip can develop into a much larger crack. Once the crack extends across a significant portion of the windshield or reaches the outer edge, repair may no longer be suitable.
Road vibration, rough surfaces, seasonal temperature changes, moisture, and additional impacts can contribute to damage spreading. Acting early gives you more opportunity to determine whether repair is still possible.
Multiple Impact Points And Extensive Damage
One isolated chip and several damaged areas are not necessarily the same situation.
Multiple impact points that weaken the glass are among the circumstances where replacement may be recommended. If damage has spread across the windshield, a full replacement may also be necessary.
Rather than trying to judge the condition of the entire windshield yourself, have the glass inspected so the extent of the damage can be properly evaluated.
Damage Affecting Visibility
A windshield needs to provide a clear view of the road. If damage significantly affects the driver's visibility, replacement may be recommended even when the damage does not initially appear extensive.
Damage in the driver's direct line of sight is an important factor when determining whether windshield repair is appropriate.
Damage Inside The ADAS Camera Zone
Modern vehicles may have Advanced Driver Assistance Systems (ADAS), including features such as lane departure warnings and automatic emergency braking. Many of these cameras and sensors are mounted directly on or behind the windshield.
When a windshield is replaced, these cameras may need to be recalibrated. ADAS calibration may be required when cameras or sensors are affected by the replacement.
What Happens If You Wait — Ontario Freeze–Thaw Cycles
A chip that looks unchanged today may not stay that way.
Ontario's freeze-thaw cycle can be challenging for chipped glass. Water can freeze inside a damaged area, while temperature changes, potholes, speed bumps, rough roads, and other everyday driving conditions can contribute to a chip becoming a crack.
Other situations that may contribute to spreading damage include:
- Blasting the defroster on a frosty morning
- A hot day followed by a cold night
- Freezing rain or snow entering the damaged area
- Slamming a vehicle door with the windows up
- Driving over potholes or speed bumps
This is one reason early assessment matters. If the damage is still suitable for repair, addressing it before it spreads may help you avoid needing a full replacement.
Cost, Time And Insurance Comparison
Cost and timing can also be part of the decision when comparing windshield repair vs replacement. A repair is generally a quicker process when the damage meets the conditions for repair, while replacement involves removing the damaged windshield and installing appropriate replacement glass. The exact time required can vary depending on the vehicle and the work involved.
Windshield repair is generally a more limited process. Westgate explains that its repair process includes inspecting the damage, cleaning debris and moisture, injecting clear resin, curing it with UV light, and polishing the repaired area. The company notes that most repairs are completed quickly.
Replacement involves removing the damaged windshield and installing the appropriate replacement glass. Many replacements can be completed the same day, although the exact service time depends on the vehicle and work required.
Insurance can also affect your out-of-pocket cost. Westgate offers insurance claim assistance and states that its team can help with the claims process. Coverage and deductible arrangements depend on the applicable insurance policy.

FAQs
1. Is My Windshield Chip Repairable?
A chip may be repairable when it is small, has not spread extensively, is away from the windshield edge, and does not significantly affect the driver's view. Westgate recommends professional assessment because the condition of each windshield is different.
2. What Is The Windshield Crack Size For Repair?
Repair is often possible when a crack is less than three inches long, provided other repair conditions are also met. The damage should also be assessed based on its location, extent, and effect on visibility.
3. When Should I Repair A Windshield Crack?
It is best to have windshield damage assessed as soon as you notice it. Temperature changes, road vibration, potholes, moisture, and other everyday conditions can cause a small chip to spread.
4. Can A Windshield Be Repaired Instead Of Replaced?
In many cases, yes. A repair-first approach may be appropriate when the damage meets the conditions for repair. If the damage has spread extensively, reaches the edge, involves multiple impact points, or significantly affects visibility, replacement may be recommended instead.
5. Will My Windshield Need ADAS Calibration After Replacement?
It may be required. If your vehicle has cameras or sensors mounted on or behind the windshield, recalibration may be required after replacement. ADAS calibration may be needed when these systems are affected.
6. Does Insurance Cover Windshield Repair Or Replacement?
Coverage depends on your insurance policy. Westgate provides insurance claim assistance and can work with customers through the insurance process. The applicable deductible and coverage should be confirmed for your individual policy.
