Broken Side Window? Here's What You Need to Know
Unlike your windshield, the side windows in your vehicle are made of tempered glass — designed to shatter into thousands of small, blunt cubes instead of sharp shards. That's a safety feature, but it also means a broken side window can't be repaired — it has to be replaced. The good news: replacement is usually fast, and we clean up every last piece.
The side glass we replace:
- Front & rear door glass — the windows that roll up and down
- Quarter glass — the small fixed (or pop-out) windows near the rear pillars
- Vent glass — the small triangular windows by the side mirrors
- Rear door & sliding windows — including trucks, SUVs, and vans
Sometimes the glass is fine and it's actually the window regulator or motor that failed — the window won't go up or down even though it's not broken. We'll diagnose which it is before you pay for the wrong fix.

Side Window Replacement Done Right
A broken side window is more than an inconvenience — it leaves your interior exposed to Portland's rain and to anyone walking by. And the damage is messier than it looks: a shattered tempered window scatters thousands of tiny glass cubes down into the door cavity, the seat tracks, the carpet, and the defroster vents. A rushed job that just drops in new glass and leaves the rest behind means rattles, re-cuts, and glass you'll be finding for months.
At Collision Auto Glass & Calibration, we've been replacing auto glass across the Portland metro since 2008. We're family-owned, locally operated, and we treat every vehicle like our own. Our certified technicians match the correct tempered glass to your exact vehicle, fully clean out the door and interior, install the new window, and test the regulator so it rolls up and down smoothly and seals against the weather the way the factory intended. Every install is backed by our work for as long as you own the vehicle. That's why we're "Clearly the Best Choice" for auto glass in Portland.
Our Side Window Replacement Process
A proper side window replacement is as much about cleanup and fit as it is about the glass. Here's how we do it:
- Assessment — We confirm whether you need glass, a regulator, or both, and match the exact tempered glass to your year, make, and model.
- Full glass removal & cleanup — We vacuum out the door cavity, seat tracks, carpet, and vents so there are no loose cubes left to rattle around or work their way back up later.
- Glass installation — We set the new window into the door and seat it correctly against the seals and guides.
- Regulator & seal check — We test the window up and down, confirm it seals fully, and make sure there are no leaks, rattles, or wind noise.
- Final clean — We wipe down the glass and interior so your vehicle comes back cleaner than we found it.
Most side window replacements are done same-day, and you drive away with a window that works and an interior that's actually clean.

We Work With All Major Insurance Providers
We Clean Up Every Last Piece
This is where most shops cut corners. When a tempered window shatters, it doesn't break into a few big pieces — it explodes into thousands of small cubes that scatter into the door cavity, down into the seat rails, deep in the carpet, and into the defroster vents. A shop that just vacuums the seat and drops in new glass leaves all of that behind, and you'll be finding glass for months — plus the pieces left inside the door rattle and can jam the new window.
We don't do that. Every side window replacement includes a complete cleanup: we open up the door, vacuum the cavity, clear the seat tracks and carpet, and make sure your vehicle leaves cleaner than it came in. It's the difference between a real replacement and a patch job.

Why a Quality Replacement Matters
Side glass isn't just a pane in a frame — it has to fit the door precisely, seal against the weather, and move smoothly on the regulator track. A poor installation shows up fast:
- Wind noise and whistling at highway speed
- Water leaks into the door and onto your interior
- A window that binds, drops, or won't seal at the top
- Leftover glass in the door cavity that rattles and jams the mechanism
We match the correct glass, clean the track, and test the full range of motion before we call it done — so your window works and seals exactly like it did from the factory.
Glass Quality: OEM vs. OEM-Equivalent
We install high-quality OEM-equivalent tempered glass that meets the same safety standards as your original — the right tint, the right thickness, and a precise fit for your vehicle. For most side windows, OEM-equivalent glass is indistinguishable from factory and saves you money.
For some vehicles, we recommend using OEM-branded glass if there's a dramatic difference in quality. We'll always tell you up front what glass we're using and why, so you can make the call.
