Vent glass replacement in Calgary and Airdrie
Small window by the side mirror or at the back of a rear door broken? Tell us your vehicle and we’ll check what you have.

- Vent glass is the small, narrow window next to the main door window, either at the front of a front door beside the side mirror or at the back of a rear door, on vehicles that have one.
- It is a separate piece from the main door glass, so your year, make and model, along with which one is damaged (driver or passenger, front or rear), identify the replacement needed.

What is vent glass?
It’s a small window next to the main door window. The front one sits right beside your side mirror. Many SUVs and vans also have one at the back of each rear door. On some vehicles it’s fixed. On others it opens. Many newer vehicles don’t have one at all. Not sure if yours is vent glass? Send us a photo and we’ll tell you.
Tell us about it
A few details help us get it right:
- Which one: driver or passenger, front or rear
- Whether it opens or stays fixed
- Whether the glass is shattered, cracked or missing
Until we get to you
If the glass is missing, heavy plastic taped over the opening keeps rain and snow out.
