If you have a cracked windshield in Ottawa, the first question is usually about the damage. The second is almost always: how long is this going to take? You have work, school runs, and a life that does not pause because a stone came off Highway 417 and found your glass. The good news is that a windshield replacement is normally a same-day job. Here is what the day actually looks like, step by step, so you can plan around it.

The Short Answer

For most cars, trucks, and SUVs, the hands-on replacement work takes about one to two hours. That covers removing the damaged windshield, preparing the frame, fitting the new glass, and sealing it correctly. After that, the adhesive needs curing time before the vehicle is safe to drive, and if your vehicle has a forward-facing camera, ADAS calibration adds time on top. When you book, ask what applies to your specific vehicle so there are no surprises.

Step One: Check-In and Inspection

When you arrive at our Ottawa shop at 2584 Edinburgh Pl, Unit #9, we confirm the correct glass for your vehicle and inspect the damage and the frame around it. If there is any rust, old adhesive buildup, or a bent pinch weld from an earlier repair, it needs attention before the new glass goes in. Skipping this step is how leaks and wind noise happen later, so a careful shop will never rush it.

Step Two: Removing the Old Windshield

The trim and wipers come off, and the damaged windshield is cut out using specialist tools that protect the painted frame underneath. All of the old adhesive is removed down to a clean, prepared surface. This is also the point where a stone chip that spread across the glass, or a crack that reached the edge, stops being your problem — the broken glass is handled and disposed of safely by the shop.

Step Three: Fitting and Sealing the New Glass

The frame is primed, fresh automotive-grade urethane is applied, and the new windshield is set in place in one precise movement. Alignment matters: a windshield that sits even slightly off can affect how mouldings fit, how sensors read the road, and whether the seal stays watertight through an Ottawa winter. Once set, the glass is checked all the way around the seal.

Step Four: Curing Time — the Part You Cannot Rush

This is the step drivers most often underestimate. The urethane needs time to cure before the windshield can do its safety job in a collision or a rollover, where the glass helps support the roof and helps airbags deploy correctly. Your technician will tell you the safe drive-away time for the adhesive used on your vehicle. Driving away too early, slamming doors hard with the windows up, or taking the car through a high-pressure wash too soon can all disturb a fresh seal.

Step Five: ADAS Calibration, If Your Vehicle Needs It

Many newer vehicles have a camera mounted at the windshield that feeds lane-keeping, emergency braking, and other driver-assistance systems. When the glass changes, that camera’s view changes, so calibration is required to make sure the systems read the road accurately. We handle ADAS camera and sensor calibration in-house, which saves you a separate trip to a dealership. Calibration adds time to the appointment, but skipping it is not a safe shortcut.

How to Plan Your Day Around It

Book ahead when you can, especially during busy periods like the first cold snap or spring pothole season on Ottawa roads. Ask about same-day service availability when you call. If you cannot wait at the shop, we offer free pickup and drop-off, plus a complimentary shuttle or Uber, so your day does not have to stop. If insurance is covering the job, we handle claims end-to-end — most customers pay $0 out of pocket, and we offer up to $150 off, up to 50% off, your insurance deductible. Every replacement is backed by a lifetime warranty on installation and a one-year warranty on the glass.

Frequently Asked Questions

Can I drive my car right after a windshield replacement?

Not immediately. The adhesive needs to cure first, and your technician will give you the safe drive-away time for your vehicle. Once that time has passed, normal driving is fine.

Does calibration happen the same day?

In most cases, yes. Because we calibrate in-house, the camera calibration is normally done as part of the same appointment, right after the new glass is fitted.

What if it is raining or snowing on the day?

Ottawa weather is what it is. Replacements are done under cover at our shop, so weather rarely stops a job, but very cold conditions can affect curing guidance — follow the instructions you are given that day.

Will a replacement take longer for a truck or SUV?

It can. Larger glass, extra trim, and additional sensors can add time. When you book, tell us the vehicle so we can give you a realistic window.

Can a long crack be repaired instead, to save time?

Repairs are quicker, but they only suit small chips and short cracks in the right location. A long or edge crack needs replacement for safety. We will tell you honestly which one your windshield needs — and we beat any quote.
