If your side or rear window breaks, you may be wondering how the replacement process works. Unlike a windshield, these windows use tempered glass and follow a different installation method. Here’s what to expect when you schedule your side or rear glass replacement.

Removing Broken Glass
The first step is safely removing any broken glass. Technicians wear protective gloves and carefully vacuum all shards from the door panels, seats, and interior trim. This step is essential to prevent injury and ensure no pieces remain hidden in the vehicle.
According to the Insurance Institute for Highway Safety, replacing side windows promptly is important for maintaining occupant safety and security.
Cleaning and Preparing the Area
Once the old glass is removed, the technician inspects the window channel, regulator, and weather seals. If any components are damaged during the breakage, they are replaced or repaired. The area is cleaned thoroughly to ensure the new glass seats properly and operates smoothly.
Transport Canada recommends verifying window operation after replacement to prevent future malfunctions. You can read more in their defect investigations.
Installing the New Glass
Side and rear windows are installed differently from windshields. Tempered glass is set into the window track and secured to the regulator mechanism if needed. For stationary rear glass, a strong adhesive bond creates a watertight seal against the frame.
At Speers Auto Glass, we use OEM-quality replacement glass that meets or exceeds your vehicle’s original safety standards. You can learn more about our side window replacement services here.
Testing and Quality Checks
After installation, the technician tests the window operation several times to make sure it opens, closes, and locks properly. The seals are checked to confirm a weatherproof fit, and the glass is cleaned for clear visibility.
For rear window replacements, the defroster grid (if equipped) is tested to ensure proper function.
Tips for Care After Replacement
Once your replacement is complete, you can drive your vehicle right away. However, it’s wise to follow a few precautions:
- Be gentle when closing doors for the first day.
- Check for any unusual noises or resistance when operating the window.
- Avoid slamming the door, which can stress new seals.
