Your windshield is an important part of your vehicle that protects you from the elements while driving. However, like any glass, windshields are susceptible to damage from rocks, debris, and accidents. If a crack or chip develops that impairs your vision, it’s time for windshield replacement. The process may seem daunting if you’ve never had to do it before, but it’s generally a straightforward procedure. In this guide, we’ll break down the typical windshield replacement steps so you know what to expect.
Assessing the Damage
The first step is evaluating the damage to your windshield. Minor chips or cracks can often be repaired, but anything that compromises the structural integrity of the glass requires full replacement. Take a close look at any issues from both the outside and inside of the vehicle. Pay attention to the size and location of the chip/crack. Larger or multiple cracks may not be repairable. Cracks near the edge of the glass also often require replacement. Also, observe the spread of the damage. If you’re unsure whether repair or replacement is needed, have a professional auto glass shop inspect it. They can determine the best course of action.
Scheduling Service
Once a replacement has been deemed necessary, it’s time to schedule the work. Most auto glass companies offer mobile service, coming directly to your location for easy repair/replacement without you needing to drive anywhere. Some key factors to consider when booking are shop availability, vehicle access, loaner vehicle availability, and warranty coverage. Ensure the shop can easily access your car where it’s parked for work. Overhead or tight spaces pose challenges. Ask if a loaner car can be provided while work is done if your car will be inoperable during replacement. Check if your car insurance covers auto windshield repair or replacements to potentially save on costs.
Windshield Removal
On the day of service, the auto glass technician will first need to remove your existing damaged windshield. The process involves applying protective tape/cardboard around the windshield frame to shield the vehicle from glass chips, using electric saws or knives to cut away any urethane sealant still attached to the frame, and carefully removing the windshield, taking care not to scratch the surrounding paint with the glass. Larger panes require two people. The technician also inspects the metal frame for any damage or corrosion from prior accidental impacts.
Glass Installation
Now it’s time to install the new replacement windshield. This step involves positioning the replacement glass pane correctly in the opening. Temporary brackets may help hold it in place. Applying a thick bead of urethane adhesive/sealant around the entire windshield perimeter on the metal frame. Carefully place the glass into the frame and press it flush against the vehicle to bond the sealant. Using specialized tools to shape and tool the sealant for a smooth, water-tight seal around all edges.
Quality Inspections
Before the vehicle is returned to you, the auto glass shop will perform quality checks on the new installation. This involves inspecting the sealant bead for uniformity, voids, and full bonding contact with glass and metal. Checking for proper glass positioning with even gaps around the frame. Testing for leaks by spraying or dripping water around the perimeter seal. Verifying no binding or obstructions when opening/closing components near windshield like wipers, sunroof, etc.
