When planning a window replacement in Calgary, one of the most frequently asked questions is: how long does it take to install windows? Understanding the installation timeline is essential for homeowners who want to plan accordingly and minimize disruptions during the renovation process.
In this comprehensive guide, we’ll break down the average time needed to install windows, factors that influence installation speed, and how to prepare for a smooth and stress-free window replacement experience. Whether you’re updating a few windows or replacing every window in your home, this article will help you estimate your project duration.
Average Window Installation Time
The time required for window installation depends on several variables. However, here’s a general rule of thumb:
| Project Type | Average Time |
|---|---|
| Single Window Installation | 30–60 minutes |
| Small Home (5–10 windows) | 1 day |
| Medium Home (10–20 windows) | 1–2 days |
| Large Home (20+ windows) | 2–3 days |
A professional installation team typically works efficiently to install one standard window in less than an hour. However, this time can increase depending on the window’s size, complexity, and accessibility.
Factors That Affect Installation Time
1. Number of Windows
Naturally, the more windows that need to be replaced, the longer the process will take. A project involving just a few windows might be completed in a single day, while a full-home replacement can stretch over several days.
2. Type and Style of Windows
Not all windows are created equal—some styles take longer to install due to their size, design, or custom features.
- Standard Vinyl Windows – Quickest to install due to simplicity and standardized dimensions.
- Bay or Bow Windows – Require additional framing and sealing, extending the installation time to several hours.
- Casement and Awning Windows – May need more adjustments and time compared to double-hung windows.
- Custom Windows – Often demand precision fitting and can delay the overall process.
- Energy-Efficient or Triple-Pane Windows – Heavier and more complex to seal, these may take slightly longer to install but offer long-term savings.
3. Full-Frame vs. Retrofit Installation
There are two main methods of installation, and the one you choose significantly affects the timeline:
- Full-Frame Installation – Involves removing the entire window frame down to the studs. This is more time-consuming but offers a completely new structure.
- Retrofit (Insert) Installation – Faster and less invasive. It uses the existing frame, making it a great option when the frames are still in good condition.
4. Condition of Existing Frames
Frame condition plays a big role. If the current frames are rotted, warped, or damaged, repairs will be needed before new windows can be installed. This can extend your project by several hours or even days, especially in older homes.
5. Weather Conditions
Calgary’s climate can be unpredictable. Heavy rain, snow, or freezing temperatures can delay work, especially during a full-frame installation. Ideally, installations are scheduled in mild, dry weather. In the winter months, installers may still work using protective barriers or heaters, but weather can still impact timing.
6. Accessibility and Home Layout
Hard-to-reach windows—like those on higher floors or behind landscaping—take longer due to the extra equipment and setup needed. Steep slopes, narrow driveways, or difficult-to-navigate homes require additional care and time.
7. Experience and Crew Size
A well-trained, experienced crew will finish the job faster than a small or inexperienced team. Larger teams can handle more windows at once, especially on bigger homes. A single installer working solo will take significantly longer.
Step-by-Step Window Installation Timeline
Understanding the phases of installation helps homeowners prepare better and know what to expect.
Pre-Installation (Before Install Day)
- Window Measurements & Inspection – A technician visits to measure the window openings accurately.
- Product Selection – Choose the type, style, and features of your new windows.
- Custom Manufacturing (if applicable) – Windows are made to order; this typically takes 2–4 weeks.
- Scheduling Installation – Date is confirmed based on your availability and weather considerations.
Installation Day Process
- Arrival & Setup – The crew arrives and sets up work areas.
- Removing Old Windows – One window at a time is carefully removed.
- Frame Inspection – Technicians check for damage or rot and perform repairs if necessary.
- Installing New Windows – New windows are set, leveled, and fastened securely.
- Insulation and Sealing – Gaps around the frame are insulated with foam and sealed.
- Functionality Check – Windows are tested for smooth operation and proper sealing.
- Interior & Exterior Trim – If required, trims and finishes are added for a clean look.
Post-Installation
- Cleanup – Old windows and debris are removed from the property.
- Final Walkthrough – Installers review the completed work with the homeowner.
- Touch-Ups – If needed, caulking or paint touch-ups are done.
How to Prepare for a Fast and Smooth Installation
To make sure the installation goes as efficiently as possible:
- Clear Window Areas – Move furniture, curtains, and blinds away from the work zones.
- Provide Easy Access – Ensure driveways and paths are clear.
- Inform Installers of Known Issues – Mention any known rot or damage beforehand.
- Secure Pets and Children – Keep them away from work areas for safety.
- Confirm Timing and Schedule – Talk to your installation company ahead of time to avoid surprises.
Common Questions About Window Installation
Can I Stay Home During Installation?
Yes, you can remain at home during installation. There will be noise and movement throughout the house, so some homeowners prefer to step out during part of the day.
Will My Home Be Cold?
Installers typically remove and replace windows one at a time, minimizing heat loss. However, some heat escape is expected, especially in winter.
Can I Use My New Windows Right Away?
Most windows can be opened and used right after installation, but some caulking and sealing materials may require up to 24 hours to fully cure.
Do I Need to Be Present All Day?
It’s recommended to be available during installation to answer questions and inspect the final result. If you can’t stay the whole time, coordinate check-ins with the team leader.
How Long Does It Take From Order to Completion?
Aside from actual installation time, homeowners should factor in the total project duration, including ordering and scheduling.
| Stage | Estimated Time |
|---|---|
| In-Home Consultation | 1–2 days |
| Window Manufacturing | 2–4 weeks |
| Installation | 1–3 days |
| Total Project Timeline | 3–5 weeks |
