How long should a windshield replacement take?
Most windshield replacements for a standard car take about 60 to 90 minutes of on-site work, with the full appointment typically lasting 2 to 3 hours, depending on curing and calibration needs. This timeline can vary by vehicle type, damage severity, and the shop’s procedures.
What to expect during a standard replacement
Here's a typical timeline for an on-site windshield replacement. It covers the core labor and common steps, from removing the old glass to securing the new one and performing safety checks.
- Removing the damaged windshield and cleaning the pinch weld
- Applying adhesive and setting the new windshield into place
- Reconnecting any sensors, antennas, or other components integrated into the windshield
- Testing functionality, resealing edges, and cleaning up the work area
In most cases, the on-site work completes in about an hour to an hour and a half; the remaining time is spent waiting for the adhesive to achieve a safe hold and performing checks, which can push the total to 2-3 hours. If the vehicle requires ADAS calibration or other follow-up steps, the appointment may extend further.
Factors that influence duration
Time can vary widely depending on several factors, including the vehicle, damage, and system requirements. The following list outlines common elements that affect how long a windshield replacement takes.
- Vehicle type and windshield design: sedans vs SUVs, curved glass, and any embedded features
- Damage extent and accessibility: edge cracks or body damage complicate removal
- Adhesive type and cure process: some adhesives require longer initial set times
- ADAS and calibration needs: camera-based systems may require on-site or off-site calibration
- Temperature and humidity: extreme cold or heat can slow curing or affect handling
- Shop workflow and technician experience: mobile vs shop-based service; availability of equipment
Conclusion: The core replacement can be quick for simple cases, but complexity and calibration requirements can add significant time. Always check with the shop for a written estimate of the total appointment duration.
ADAS calibration and adhesive curing: what to expect
ADAS calibration
Vehicles equipped with Advanced Driver Assistance Systems may require calibration after windshield replacement to ensure sensors and cameras align correctly. Depending on the system, calibration can take 30 to 90 minutes or longer, and some cars require off-site calibration or a specialized rig. If a calibration is needed, the shop will advise whether it can be done during the same visit or requires a separate appointment.
Adhesive curing and drive-away timing
Most installers use polyurethane adhesive that achieves a safe initial hold within about an hour, allowing the vehicle to be driven away, but full cure and maximum bond strength can take up to 24 hours. During the curing window, shops typically instruct customers to avoid car washes, exposure to heavy loads, or exposing the glass to direct water pressure. Always follow the installer’s specific guidance for your vehicle and adhesive used.
Note: The exact drive-away time and cure intervals vary by manufacturer and vehicle model; confirm with your installer.
Tips to plan and speed up the process
Preparation and clear communication can help keep the appointment on schedule. The following checklist helps you plan.
- Bring your vehicle’s VIN, insurance information, and any required authorization for the repair
- Ask whether ADAS calibration is included and whether it will be performed on-site or requires a separate visit
- Clarify the expected drive-away time and any restrictions (car wash, heavy acceleration, etc.)
- Ensure the work area is accessible and that the vehicle can be parked safely for the appointment
Conclusion: By confirming these details beforehand, you minimize delays and obtain a realistic timeline for the appointment.
Summary
Windshield replacement times vary, but most standard jobs take about 60-90 minutes of hands-on labor, with the overall appointment commonly spanning 2-3 hours. Additional factors like ADAS calibration, complex windshields, weather, and the shop’s workflow can extend the timeline. If in doubt, ask your installer for a written estimate that covers labor, adhesive cure, and any required calibrations, and plan for potential delays in case of equipment or weather-related issues.
