Replacing a windshield typically takes about 60 minutes for the installation itself. However, the entire process including preparation, installation, and adhesive curing usually requires around 1.5 to 2 hours in total. Key points about the time involved:

• The actual installation by an experienced technician often takes less than an hour, sometimes as quick as 15 to 20 minutes for straightforward cases

• Newer vehicles with advanced features like sensors and cameras (ADAS) may require additional time for calibration, adding 30 minutes to an hour or more

• After installation, the urethane adhesive used to seal the windshield must cure for at least one hour before driving is safe

• Some technicians recommend waiting longer (up to 8 hours) before subjecting the vehicle to any stress or high-pressure washing to ensure full adhesive strength

• Overall, you can expect to spend between 1.5 to 2 hours from start to finish, including drying time

In summary, while the physical replacement is often done within an hour, the necessary curing time means you should plan for about two hours before the vehicle can be driven normally. For vehicles with advanced technology, additional calibration time may extend this slightly.
