What to Expect When Getting Your Windows Replaced: An Alberta Homeowner's Guide

You have done the research. You have compared quotes. You have signed with a company. Now what?

If you have never had your windows replaced before, the period between signing the contract and installation day can feel like a black box. Most companies give you a timeline and a date, but nobody walks you through what actually happens at each stage.

This guide covers the entire process from start to finish: the initial consultation, what happens between signing and install day, what installation day actually looks like hour by hour, and what to check during your final walkthrough. All timelines are based on what Alberta homeowners actually experience, including seasonal demand and weather factors.

Stage 1: The Initial Consultation

The process starts with a consultation, either at your home or virtually. Here is what a professional consultation should include.

The Measurement Visit

A qualified estimator will come to your home and physically measure every window opening. This is not a quick drive-by. For a 10-window project, expect the measurement visit to take 45 minutes to an hour.

The estimator measures three things for each window:

• Width and height of the existing window opening
• Depth of the frame cavity (this determines which window profiles will fit)
• Condition of the rough opening and surrounding wall structure

Good estimators also check for:

• Signs of water damage or rot around existing frames
• Insulation gaps behind interior trim
• Whether the window opening is square (older Alberta homes often have settled frames that are slightly out of square)

The Recommendation

After measuring, the estimator will walk you through their recommendations:

• Glass package: double pane vs triple pane (for Alberta, triple pane is almost always the right call)
• Window style: casement, hung, slider, picture, or a mix based on each opening
• Frame material: most Alberta companies recommend vinyl for the best balance of performance and value
• Structural considerations, such as windows that need resizing, headers that need reinforcement, or openings with hidden damage

A good consultation feels like education, not a sales pitch. You should leave with a clear understanding of what you are getting and why.

For help evaluating quotes once you receive them, our quote guide breaks down exactly what each line item should include.

Stage 2: Between Signing and Installation

This is the stage nobody talks about: the 4-8 week gap between signing your contract and installation day. Here is what is happening behind the scenes.

Week 1-2: Order Processing

Your windows are custom-built to the exact measurements taken during the consultation. The order goes to the manufacturer with specifications for each opening: size, style, glass package, frame colour, hardware colour, and any custom options.

In Alberta, most residential windows are manufactured in Western Canada. Order processing and production typically take 4-6 weeks. During the spring rush (March through May), lead times can extend to 6-8 weeks as manufacturers run at full capacity.

Week 3-5: Manufacturing

Each window is built to your specific dimensions. This is not off-the-shelf product. Manufacturing includes:

• Frame extrusion and cutting
• Glass unit assembly (cutting, spacer application, gas fill, sealing)
• Hardware installation
• Quality inspection and pressure testing

Week 5-7: Scheduling

Once your windows are built and shipped to the installer's warehouse, the scheduling coordinator contacts you to book your installation date. You will typically get a choice of dates within a 1-2 week window.

What You Should Do During This Wait

While your windows are being built, prepare your home:

• Clear the area around each window. Move furniture, curtains, blinds, and wall decorations at least 3 feet back from every window being replaced.
• Check your exterior. If you have garden beds, planters, or patio furniture directly below windows, move them out of the way.
• Plan for pets. Dogs and cats get stressed by strangers, power tools, and cold air. Arrange to keep them in a separate room or with a neighbour on installation day.
• Notify your neighbours. A courtesy heads-up about a work crew and noise is always appreciated, especially in attached homes or condos.
• Clear your driveway. The crew needs space for their truck and materials near your front entrance.

Stage 3: Installation Day

This is the day it all happens. Here is what a typical installation day looks like for a 10-window project in Alberta.

7:30-8:00 AM: Crew Arrival and Setup

The installation crew arrives, usually 2-4 people depending on project size. They will:

• Introduce themselves and walk through the plan for the day
• Lay down drop cloths and protective coverings on your floors and furniture near the work areas
• Set up their tools and staging area (usually in your garage or on the driveway)
• Bring all your windows inside or into the garage to prevent cold exposure to seals and weatherstripping

8:00 AM: First Window Begins

The crew works on one window at a time. For each window, the process follows the same sequence:

Step 1: Remove interior trim (5-10 minutes) The casing around the window is carefully removed. In many Alberta homes, this reveals the original insulation (or lack thereof) behind the frame.

Step 2: Remove the old window and frame (10-20 minutes) For full-frame installation, the entire old assembly comes out: window, frame, and any deteriorated material. This is when the crew can see the rough opening and identify any issues.

Step 3: Inspect and prepare the opening (5-15 minutes) The crew inspects for rot, mould, water damage, and insulation gaps. Any issues are addressed before the new window goes in. Missing insulation is added. Damaged framing is repaired.

Step 4: Install the new window (15-25 minutes) The new window is shimmed, levelled, and secured in the opening. Spray foam insulation is applied around the perimeter. The window is tested for smooth operation. Every sash should open, close, and lock cleanly.

Step 5: Exterior finishing (10-20 minutes) Aluminum capping is applied to the exterior frame. Exterior-grade caulking is applied to seal against weather. In Alberta, this caulking must be rated for temperatures down to -40C.

Step 6: Interior trim (10-15 minutes) Interior casing is installed. Some companies use PVC trim (maintenance-free); others use wood. The trim is measured, cut on-site, and attached with finish nails.

Total per window: 45-90 minutes depending on size, accessibility, and any surprises behind the old frame.

Midday Check-in

Around lunchtime, the crew lead will usually check in with you:

• How the project is progressing
• Any issues discovered (rot, insulation gaps, structural concerns)
• Updated timeline for completion
• Whether any decisions need your input

Temperature Management

This is the question every Alberta homeowner asks: "Won't my house be freezing?"

The honest answer: the room where the crew is working will drop 1-3 degrees while a window opening is exposed. But because the crew replaces one window at a time and temporarily seals each opening with plastic sheeting during the swap, your home is never wide open.

Close interior doors to rooms where the crew is not working. Those rooms will stay at normal temperature. The crew has done this hundreds of times in Alberta winters and knows how to minimize heat loss.

4:00-5:00 PM: Cleanup and Walkthrough

Once the last window is in, the crew cleans up:

• All old windows and frames loaded for disposal
• Drop cloths and coverings removed
• Floors swept or vacuumed
• Exterior debris cleared

Then comes the most important part of the day: your walkthrough.

Stage 4: The Final Walkthrough

Do not skip this. The final walkthrough is your opportunity to inspect every window before the crew leaves. Once they drive away, any issues become a callback, which means waiting for a return visit.

What to Check

Go to every window and verify:

Operation:

• Open and close each sash. It should move smoothly with no sticking or grinding.
• Lock and unlock. All hardware should engage cleanly.
• Tilt-in sashes (if applicable) should release and re-seat without force

Fit and finish:

• Check for even gaps between the frame and wall on all four sides
• Look for any visible daylight around the frame (there should not be any)
• Verify interior trim is flush with no gaps or protruding nails
• Check that caulking lines are clean and consistent

Exterior:

• Walk outside and check each window from the exterior
• Aluminum capping should be flush with the wall, with no gaps or lifted edges
• Caulking should be continuous with no breaks
• Weep holes (small drainage slots at the bottom of the frame) should be clear and unobstructed

Glass:

• Check for scratches, chips, or imperfections in the glass
• Verify that the glass package is correct (triple pane should show three reflections when you hold a lighter to the glass at night)

Stage 5: After Installation

The windows are in. The crew is gone. Now what?

First 72 Hours

• Do not wash the windows. Give caulking and sealant a full 72 hours to cure before cleaning around the frames.
• Check for condensation. Some interior condensation in the first few days is normal as your home's humidity adjusts to the new airtight seal. It should clear within a week.
• Test operation daily. Open and close each window to make sure everything is still operating smoothly after the sealants have set.

First Month

• Register your warranty if required by the manufacturer. Some do, some do not. Your installer should tell you.
• Take photos of each window from inside and outside. These serve as a baseline if you ever need to file a warranty claim years later
• Note your energy bills. Within 1-2 billing cycles, you should start seeing a reduction in heating costs. Keep your old bills for comparison.

Ongoing Maintenance

Vinyl window replacement requires almost zero maintenance, but a few simple habits will maximize the lifespan of your investment:

• Clean frames twice a year with mild soap and water
• Lubricate hardware (hinges, locks, cranks) once a year with a silicone-based lubricant
• Clear weep holes in spring. These small drainage slots can get blocked by dust, paint, or debris.
• Inspect weatherstripping annually for wear or compression
• Clear ice buildup from tracks in winter before it damages the weatherstripping

Realistic Timelines for Alberta

Every project is different, but here is what typical Alberta homeowners experience:

Stage	Timeline	Alberta Notes
Consultation to signed contract	1-2 weeks	Faster if you have already compared quotes
Manufacturing	4-6 weeks	6-8 weeks during spring rush (Mar-May)
Scheduling	1-2 weeks	Weekday slots often available sooner
Installation (10-15 windows)	1-2 days	Weather delays rare (crews work in winter)
Total: consultation to finished	6-10 weeks	8-12 weeks if ordering during spring peak

The biggest variable is manufacturing lead time. If you are planning a project for a specific season, book your consultation 2-3 months ahead to secure your preferred installation window.

The Bottom Line

Window replacement is a straightforward process, but only if you know what to expect at each stage. No surprises, no anxiety, just a clear path from "I need new windows" to "these look great."

The companies that walk you through this process upfront, explaining every stage, setting realistic timelines, and doing a thorough walkthrough at the end, are the companies worth trusting with your home.
