Subaru WRX & STI (2015-2021) Back Glass Replacement
If you drive a 2015 to 2021 Subaru WRX or STI, you already know it is built for performance. But when that back glass shatters—whether from a stray rock on the highway or a sudden temperature drop—you need it fixed fast and right. The rear window on this specific VA chassis isn't just a simple piece of glass. It houses your defroster grid and fits tightly against the rear pillar trim and trunk line. A sloppy install easily leads to annoying wind noise, water leaks, or a dead defroster. I've replaced hundreds of these, and doing it correctly takes patience, the right tools, and exact techniques.
At AlexWindshield, we bring the shop directly to your driveway. We provide dedicated mobile auto glass service across the Greater Toronto Area (GTA). Whether you have your car parked at home in Vaughan, at the office in Richmond Hill, or out in Markham, we show up with the exact replacement glass and get your Subaru back on the road safely.
How We Replace Your WRX/STI Rear Window
Replacing tempered back glass requires precise work to protect your interior and ensure a factory-grade seal. Here is exactly how we handle the job in the field:
- Interior Protection: First, we lay down heavy protective blankets over your rear seats, the parcel shelf, and inside the trunk. Shattered tempered glass explodes into thousands of pieces, and we take the time to vacuum every corner so your interior stays spotless.
- Safe Removal: We carefully disconnect the defroster wiring and remove any remaining glass chunks. Next, we cut back the old factory urethane bead down to a thin, even layer, making sure we never scratch the pinch weld.
- Surface Cleaning & Prep: The bare metal and existing urethane track are thoroughly cleaned to remove dust, dirt, and old debris. If there are any tiny scratches on the pinch weld from previous work, we treat them immediately to prevent future rust.
- Primer & Adhesive Application: We apply a specialized auto glass primer to the glass band, followed by a fresh, continuous bead of premium, fast-curing urethane adhesive. This step guarantees a watertight, structural seal.
- Precision Installation: The new back glass is carefully set into place and aligned perfectly with your Subaru's roofline and trunk gaps. We hook the defroster lines back up, secure the surrounding trim, and clean the new glass inside and out.
