Back & Rear Window Replacement
Family-Owned & Operated Since 2008
Broke Your Back Window? Here's What You Need to Know
Your rear window is tempered glass — like your side windows, it's designed to shatter into thousands of small, blunt cubes rather than sharp shards. That means a broken back window can't be repaired; it has to be replaced. But rear glass is more involved than a side window: on most vehicles it's bonded into the body with urethane (like a windshield) and it carries built-in features that have to be matched and reconnected.
What's usually built into your back glass:
- Rear defroster grid — the thin heating lines that clear fog and frost
- Radio antenna — many vehicles run the antenna through the rear glass
- Third brake light, wiper, or tint — depending on your make and model
If those aren't matched to your exact vehicle and reconnected properly, you end up with a back window that fogs up in winter, a dead radio, or leaks down the road. We get all of it right.

Back Window Replacement Done Right
A broken rear window leaves your cargo area and back seat exposed to Portland's weather and to anyone walking by — and it's a messy break. A shattered tempered window scatters thousands of glass cubes into the trunk, the rear seats, the cargo carpet, and every crevice in between. But the bigger challenge is what's built into the glass: the defroster grid, the antenna, and on many vehicles a bonded urethane seal that has to be done to the same standard as a windshield.
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 glass to your exact vehicle — defroster grid, antenna, tint, and all — bond it with premium urethane where the design calls for it, reconnect every feature, and fully clean out the glass before we hand back your keys. 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 Back Window Replacement Process
Rear glass takes more than dropping in a pane — here's how we do it right:
- Assessment — We match the exact glass to your year, make, and model, including the defroster grid, antenna, and any tint or built-in features.
- Full glass removal & cleanup — We vacuum out the trunk, cargo area, back seats, and every crevice so there are no loose cubes left to rattle around or work their way out later.
- Frame prep — We clean and prep the bonding surface so the new glass seats and seals correctly.
- Glass installation — We set and, where the design calls for it, bond the new glass with premium urethane for a watertight seal.
- Reconnect & test — We reconnect the defroster and antenna, confirm the defroster heats evenly, and check for leaks, rattles, and wind noise.
- Final clean — We wipe down the glass and interior so your vehicle comes back cleaner than we found it.
On bonded rear glass, we'll give you a safe drive-away time so the urethane cures properly — usually about an hour. We'll tell you exactly when it's ready.

We Work With All Major Insurance Providers
We Match and Reconnect Your Defroster and Antenna
Here's what separates a real rear-glass replacement from a patch job. Your back window isn't just glass — it has a defroster grid printed into it and, on many vehicles, your radio antenna running through it. A shop that grabs the closest universal pane and skips the connections leaves you with a rear window that fogs over the first cold Portland morning and a radio that won't pull in a station.
We match the glass to your exact vehicle so the defroster grid lines up, bond it correctly, and reconnect every feature — then we power on the defroster and confirm it heats evenly across the whole window before we call it done. You get a back window that works exactly like the one you lost.

Why a Quality Replacement Matters
Rear glass has to fit precisely, seal against the weather, and keep every built-in feature working. A poor installation shows up fast:
- A defroster that doesn't heat — or heats unevenly — leaving you scraping fog in winter
- Water leaks into the trunk or cargo area
- A dead or weak radio from a botched antenna connection
- Wind noise, rattles, and leftover glass shifting around inside the body
We match the correct glass, bond it properly, reconnect and test every feature, and clean out every piece before we call it done — so your rear window works and seals exactly like it did from the factory.
Glass Quality: OEM vs. OEM-Equivalent
We install high-quality OEM-equivalent rear glass that meets the same safety standards as your original — correct defroster grid, antenna, tint, and a precise fit for your vehicle. For most rear 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.
