FAQs

Driving with a cracked or damaged windscreen is not considered safe, even when the damage appears small. Modern windscreens are a structural safety component, contributing to roof strength, passenger protection, and proper airbag deployment. A crack weakens the laminated glass, reducing its ability to withstand impact forces and increasing the risk of sudden failure while driving.

Beyond structural concerns, cracks and chips can distort vision, create glare, and reduce clarity — particularly in bright sunlight, wet conditions, or night driving. These effects often worsen over time as the damage spreads.

Under NSW roadworthiness requirements, a vehicle must not be driven if the windscreen obstructs the driver’s view or compromises safety. Cracks, chips, or damage within the driver’s primary viewing area are commonly grounds for a defect notice or failed inspection.

Even damage outside the direct line of sight may be considered unsafe if it affects visibility, weakens the windscreen, or has the potential to spread. Police and inspectors assess windscreens based on visibility, size, location of damage, and safety risk, not just whether the glass is completely shattered.

A damaged windscreen can significantly affect visibility through optical distortion, light refraction, and glare. Small cracks and chips bend light unevenly, which can blur vision, exaggerate reflections, and make hazards harder to detect — especially during sunrise, sunset, or in wet weather.

Reduced visibility increases reaction time and driver fatigue, particularly on longer drives. Over time, dirt and moisture entering damaged areas can worsen distortion and clarity issues.

Yes. The windscreen acts as a support surface for front passenger airbags. During a collision, airbags deploy at high speed and rely on the windscreen to remain firmly bonded in place. If the glass is cracked, weakened, or poorly bonded, the airbag may deploy outward rather than toward the passenger, reducing its effectiveness and increasing injury risk.

This is one of the key reasons manufacturers and safety standards treat windscreen condition as a critical safety factor, not just a cosmetic issue.

Cracks and chips can spread rapidly, sometimes within hours or days. Common triggers include temperature changes, road vibration, vehicle body flex, and moisture entering the damaged area. In coastal environments like the Northern Beaches, salt air and humidity can accelerate deterioration of both the glass and surrounding seals.

What begins as a small chip can quickly expand into a full-length crack, turning a repairable issue into a required windscreen replacement.

In most cases, cracked windscreens cannot be safely repaired. Repair is generally limited to small stone chips, not cracks. Once a crack forms, the laminated structure of the glass has been compromised, and resin repair cannot restore the windscreen’s original strength or safety performance.

Cracks tend to continue spreading due to vibration, temperature changes, and body flex — even after attempted repair. For this reason, manufacturers and safety standards typically require full windscreen replacement when cracks are present.

Windscreen repair is usually limited to small chips that meet all of the following conditions:

• The chip is small (typically around the size of a coin or smaller)
• The damage is not in the driver’s primary line of sight
• The chip is away from the edges of the windscreen
• The damage is recent and has not absorbed moisture or contaminants

When these conditions are met, a professional chip repair can stabilise the damage and help prevent it from spreading. If any of these conditions are not met, replacement is the safer option.

Windscreen replacement is required when:

• There is any crack, regardless of length
• Damage is located in the driver’s line of sight
• The chip is near the edge of the glass
• There are multiple impact points
• The windscreen has been previously repaired and failed
• Structural integrity or airbag support may be compromised

In these situations, repair does not meet safety or compliance expectations, and replacement is necessary to restore full protection.

When damage qualifies for repair, chip repair is usually less expensive than full replacement. However, delaying proper replacement can increase overall costs if the damage spreads. A small chip that isn’t addressed promptly can quickly turn into a crack, making replacement unavoidable.

From a long-term perspective, choosing the correct solution early often reduces inconvenience, safety risk, and total cost.

Yes. A repaired windscreen can still fail over time, especially if the repair was carried out on unsuitable damage or if the glass was already weakened. Environmental factors such as temperature changes, vibration, and moisture can cause cracks to form from previously repaired areas.

This is why professional assessment is essential — to determine whether repair is genuinely appropriate or whether replacement is the safer, more reliable option.

The cost of windscreen replacement depends on several factors, including the vehicle make and model, the type of glass required, and whether the windscreen integrates ADAS cameras or sensors. As a general guide, simpler vehicles without advanced systems are typically at the lower end of the cost range, while newer, luxury, or European vehicles tend to be more expensive due to specialised glass and calibration requirements.

Rather than using generic pricing, we assess each vehicle individually and provide a clear, upfront quote once the details are confirmed. There are no hidden fees or surprises after the job is complete.

Many comprehensive insurance policies include windscreen or glass cover, which may allow replacement with little or no excess. Coverage varies depending on your insurer and policy terms. Some policies include glass cover as standard, while others offer it as an optional extra.

If you’re unsure what your policy covers, we can help clarify your options before proceeding so you can make an informed decision.

Whether an excess applies depends on your insurance policy. Some policies waive the excess entirely for glass-only claims, while others require a standard excess to be paid. This can also vary depending on whether the damage is isolated to the windscreen or part of a larger claim.

We recommend confirming excess details with your insurer, and we’re happy to assist by explaining what information they may need.

Yes. In most cases, Australian consumers have the right to choose their own repairer, even if the insurer suggests a preferred provider. Choosing your own provider allows you to prioritise quality, materials, and workmanship rather than being limited to the insurer’s network.

If you plan to nominate your own repairer, we can provide the required details to assist with the claim process.

Absolutely. We always provide a clear quote before any work begins. This includes the cost of the glass, installation, and any additional requirements such as ADAS considerations. 

We believe transparency is essential — you’ll know exactly what’s involved before making a decision.

Most windscreen replacements take around 90 minutes from start to finish. This includes safe removal of the damaged glass, preparation of the vehicle, installation of the new windscreen, and final quality checks. Some vehicles may take longer depending on glass type, trim complexity, or safety system requirements.

After installation, the adhesive used to bond the windscreen requires a short curing period. In most cases, it is safe to drive after approximately 15 minutes. This timeframe can vary slightly depending on weather conditions and the adhesive used. We always provide clear drive-away guidance specific to your vehicle.

Yes. We offer fully mobile windscreen and auto glass replacement, completing the work at your home, workplace, or another suitable location. Our mobile setup allows us to deliver the same standard of workmanship you’d expect from a workshop, without requiring you to rearrange your day.

Same-day windscreen replacement is often available, subject to glass availability and your location. If your windscreen damage affects visibility or safety, we recommend contacting us as early as possible so we can prioritise the job where feasible.

A mobile windscreen replacement includes inspection of the damage, protection of surrounding trim and interior areas, safe removal of the old glass, preparation of the bonding surface, and installation of the new windscreen using manufacturer-approved adhesives. The job concludes with a final inspection and clear after-care instructions.

Some modern vehicles do require ADAS (Advanced Driver Assistance Systems) recalibration after windscreen replacement, depending on how cameras and sensors are mounted. Vehicles with lane-keeping assist, adaptive cruise control, or emergency braking systems often rely on cameras attached to the windscreen. If the camera alignment is affected during replacement, recalibration is necessary to ensure these systems operate accurately.

ADAS refers to a range of safety technologies designed to assist drivers and reduce collision risk. These systems rely on cameras and sensors to interpret the road environment. Because many of these cameras are mounted directly to the windscreen, correct installation and alignment are critical. An improperly installed windscreen can cause false warnings, reduced system performance, or complete failure of these features.

We use OEM-grade glass that meets manufacturer specifications for fit, strength, and optical clarity. OEM-grade glass is designed to integrate correctly with vehicle safety systems and ensures proper sealing and durability. Cheaper aftermarket glass can vary in thickness, clarity, and compatibility, which may affect visibility, bonding, and long-term performance.

Our lifetime workmanship warranty covers installation-related issues, including bonding, sealing, and fitment, for as long as you own the vehicle. If a problem arises due to workmanship, we’ll resolve it promptly. The warranty does not cover new damage caused by accidents, stone impacts, or external forces after installation.
