Auto glass is four or five distinct jobs that happen to involve the same material. What your car needs determines the part, the price, the time and whether it can be done in your driveway.
Windshield replacement
The big one, and the one with the most going on behind it. A modern windshield is laminated safety glass bonded to the body with structural urethane. It supports the roof in a rollover and it is the backstop the passenger airbag inflates against. That is why cure time is not negotiable and why the bonding surface matters as much as the glass.
What changes the price, in rough order of impact:
- A camera or sensor cluster behind the mirror — brings recalibration into the job
- Heads-up display — needs a specific wedge interlayer, or the projection ghosts
- Acoustic laminate — the quiet-cabin layer; substitute it and the car gets louder
- Heated wiper park — a strip of elements at the base of the glass
- Rain and humidity sensors — need the correct gel pad and mount
- Solar or shade band tint variations — trim-level dependent
Windshield chip and crack repair
Cheaper, faster, and the right answer more often than people expect. Resin is injected into the break under vacuum, cured, and polished flat. It restores the strength and stops the crack running. It does not make the damage invisible, and any shop that promises it will is overselling.
Full detail, including when repair is the wrong call, is on the chip repair page.
Door glass, back glass and quarter glass
Tempered rather than laminated, so it does not crack — it goes to granules all at once. Different job entirely:
- The glass is in the door cavity, the seat rails and the carpet, and getting it out properly is most of the labour
- Back glass usually carries defroster elements, and on many vehicles the antenna as well
- Quarter glass is often bonded rather than in a track, which makes it fiddlier than its size suggests
- Parts availability varies wildly by model and trim, so this is the category where waiting is most likely
ADAS camera recalibration
If the car has lane keeping, lane departure warning, adaptive cruise, automatic emergency braking or traffic sign recognition, there is a camera looking through the windshield. Move the glass and the camera’s aim moves with it.
Recalibration is the second half of a windshield job on these vehicles, not an accessory to it. What it involves, and why static and dynamic are different.
Fleet and company vehicles
Vans, trucks and pool cars are a scheduling problem more than a technical one — the vehicle earns while it moves, so the work goes where the vehicle already is. Multiple units at one site on one visit is the normal arrangement. Billing to the company rather than the driver needs saying at the start so the paperwork is right the first time.
What we do not do
Tint. Different trade, different regulations, and Michigan’s rules on front-side windows catch people out.
Body glass on classics and pre-1990 vehicles. Rubber-gasket-set glass on older cars is a specialist restoration job. Anybody who treats it as a routine swap will damage the pinch weld or the trim.
Rock chip repair on paint. A search for “rock chip repair” turns up both. This is glass only.
Common questions
Do you do side windows, or only windshields?
Both. Door glass and back glass are a different job from a windshield — tempered rather than laminated, so it goes to pieces instead of cracking, and the work is as much vacuuming as glazing. Say which window it is on the first call, because the parts availability is completely different.
The glass is gone and the car is sitting open. How fast can this happen?
That depends on the part more than the schedule. Common vehicles are usually quick. Anything with an unusual trim level, a heated element or an uncommon tint can take days to source. If the car is open to the weather, say so — a temporary weatherproof cover is a normal first step while the glass is ordered.
There is broken glass all through the car.
That is expected with tempered glass and it is part of the job, not an extra. Door glass shatters into the door cavity, the seat rails and the carpet, and any of it left behind works its way out for months. It gets vacuumed out properly, including inside the door.
