At our auto glass shop, one of the first questions customers ask when scheduling service is how long it will take to replace a windshield. The concern is practical. People want to know how much time to set aside in their day, whether it will affect their commute, and if their vehicle will be safe to drive afterward.
In this blog, we explain the factors that influence windshield replacement timelines, key steps involved in the process, and what drivers should know once the work is complete.
How Long Does Windshield Replacement Take?
On average, our windshield replacement in Etobicoke take about 45 to 90 minutes for most vehicles. This estimate covers the removal of the damaged glass and the installation of the new one. However, the total time can extend to two or even three hours when you account for adhesive curing and, in many cases, the calibration of modern safety systems
Factors That Affect Windshield Replacement Time
- Vehicle type and design
Windshields on newer and higher-end vehicles often have rain sensors, acoustic layers, or head-up display glass. These features require extra care and setup, which adds time compared to standard models.
- Adhesive curing
Urethane adhesives must cure before the vehicle is safe to drive. Depending on the product and environmental conditions, safe drive-away time adds 30 to 60 minutes. Skipping this stage compromises the windshield’s role in crash protection and airbag deployment.
- Advanced Driver Assistance Systems (ADAS)
If a vehicle uses cameras or sensors mounted on the windshield, recalibration is required after any windshield replacement. This process usually adds 30 to 60 minutes to the service duration, but it’s necessary for features like lane-keeping and automatic braking to function correctly.
- Weather conditions
Cold temperatures slow adhesive curing, while high humidity can affect bonding. Technicians adjust their methods and adhesive choice to account for these variables, extending the time it takes to replace windshield glass.
- Service type
In-shop replacements are usually faster because technicians work in controlled conditions, with stable temperature and no exposure to rain or dust. This consistency keeps adhesive curing within the expected 30–60 minute window, so the total service time stays around the one to two hour duration. Mobile replacements may take longer if the technician has to adjust for weather, uneven ground, or poor lighting.
At Auto Glass Pro Etobicoke, we provide mobile auto glass services at no extra cost and uphold the same standard of safety and workmanship as our in-shop service, so customers can choose the option that best fits their schedule without compromising on quality work.
What Happens During a Windshield Replacement?
A windshield replacement follows a precise sequence to make sure the glass bonds securely and the vehicle’s safety features function as intended. Each stage ensures the car is safe to drive again and determines how long it takes to get a windshield replaced.
- Removal of the old glass
Technicians begin by removing the trim, molding, and any clips or fasteners around the windshield. Specialized cutting tools are used to separate the glass from the urethane adhesive without damaging the vehicle’s frame.
- Surface preparation
Once the old glass is out, the pinchweld (the metal frame where the windshield sits) is cleaned of debris and old adhesive. A fresh layer of primer is applied to promote bonding and prevent corrosion.
- Installing the new windshield
The new glass is positioned using alignment guides to ensure a precise fit. Urethane adhesive is applied evenly around the frame, and the windshield is set in place. Proper bonding is critical, since the windshield contributes to the vehicle’s structural strength.
- Reassembly and calibration
Trim, molding, and clips are reinstalled. If the vehicle has rain sensors, cameras, or other ADAS equipment, these components are reattached and tested. Many modern vehicles require calibration at this stage to restore safety system accuracy.
- Five-point inspection before release
Auto Glass Pro Etobicoke completes every job with a five-point inspection to confirm the bond strength of the adhesive, the integrity of the seal, correct sensor calibration, trim alignment, and the absence of leaks or wind noise. This process is standard for every windshield replacement and serves as a safeguard that every vehicle leaves our shop road-ready and compliant with safety expectations.
How Long Does It Take to Fix a Windshield Instead of Replacing?
For small chips or shallow cracks, a professional auto glass repair typically takes between 15 and 30 minutes. Inside that timeframe, the technician cleans and prepares the damaged area, injects resin, removes air, exposes the resin to UV light (if needed), and polishes the surface.
Repair is suitable when:
- The chip is small (often no larger than about one inch in diameter).
- The damage does not reach or penetrate the interior (laminated) glass layer.
- The crack has not spread, branched, or extended close to the windshield edge.
- The damage is not directly in the driver’s line of sight (or the distortion would be minimal).
You need a full windshield replacement when:
- The chip or crack is larger than what can be reliably filled with resin (e.g., cracks longer than six inches).
- The damage reaches or compromises the structural layers of the windshield or edge seal.
- The crack is evolving, branching, or interfering with embedded systems (sensors, heater wires).
- The damage distortions are too severe in the driver’s view to restore acceptable clarity.
Post-Replacement Care Tips
After a windshield replacement, the way the vehicle is handled during the first few hours and days makes a significant difference in the long-term performance of the repair. The most important factor is the safe drive-away time, which refers to the point when the adhesive has cured enough to hold the glass securely under normal driving conditions. Depending on the adhesive used, as well as temperature and humidity, this can range from 30 minutes to three hours. Driving before this point risks vibrations or pressure changes that can weaken the bond and compromise safety.
If the adhesive has not reached full strength, the bond can fail, leading to leaks, wind noise, or, in severe cases, glass separation during impact. During the first 24 to 48 hours, a few precautions are critical to ensure the adhesive cures fully:
- Avoid automatic or high-pressure car washes, which can disrupt the adhesive seal.
- Close doors gently, since slamming them sends pressure waves through the frame that can disturb a curing windshield.
- Stay away from rough roads and potholes, as vibrations and jolts place extra stress on the fresh installation.
- Leave windows slightly open in hot conditions to reduce air pressure inside the cabin.
- Hold off on applying treatments such as rain repellents until at least a full day has passed.
