Choosing new windows is a big investment that can transform the comfort, energy efficiency, and beauty of your home. But even the highest-quality windows won’t perform at their best without proper installation.

That’s why understanding the installation process — and knowing what to expect as a homeowner — is just as important as selecting the right product.

What to expect

This guide walks you through the key steps from your first contact with the installation company to the moment you enjoy your new windows. Our goal is to make your experience as smooth, clear, and stress-free as possible, so you can feel confident every step of the way.

1. Reach out to a reputable company

Start by contacting a professional window installation company to begin your project. After your initial inquiry, a dedicated sales representative will reach out to you by phone to schedule an in-home consultation at a time that works best for you.

2. Schedule a free in-home consultation

A company representative will visit your home to take precise measurements, assess your existing windows, and discuss your goals. They’ll explain available options and offer expert recommendations tailored to your needs and Ottawa’s climate, ensuring your new windows fit perfectly and perform optimally year-round.

3. Review your quote

You’ll receive a detailed estimate covering all aspects of the project, including window types, materials, labour costs, warranty coverage, and expected timelines. This clear breakdown helps you make an informed decision. Take the time to ask questions, clarify details, and compare options to ensure the best fit for your needs and budget.

4. Approve the quote & provide a deposit

Once you’re satisfied with the quote and all your questions are answered, you’ll need to approve it in writing to confirm your order. This ensures both you and the company agree on the project details, including products, pricing, and timelines. At this stage, a deposit is usually required to begin manufacturing or ordering and to secure your spot in the installation schedule.

5. Window manufacturing & delivery

Once your order is confirmed, your custom windows are manufactured to your exact specifications for a perfect fit and optimal performance. Because each window is made to order, the process usually takes 4 to 10 weeks, depending on demand, order complexity, and product type. Your supplier should keep you informed about progress and the expected delivery timeline.

6. Schedule the installation

Once your custom windows arrive, the company will reach out to schedule a convenient installation date that works with your availability. They’ll provide you with details such as the expected duration of the installation and the arrival time of the crew, so you can plan accordingly. This helps ensure a smooth and well-organised installation experience.

7. Prepare your home

Preparing home for window installation

Before installation day, be sure to clear the space around your windows to allow easy access for the installers. Remove any blinds, curtains, or shutters, and secure or take away any nearby fragile items to prevent damage. If you have children or pets, consider making arrangements to keep them safe and out of the work area during the installation.

8. Installation day

When the installers arrive, they usually work one room at a time to keep the process organised and efficient. They’ll be respectful of your home and do their best to minimise disruption. While some noise, brief drafts, and dust are normal, the crew maintains a clean, professional approach and tidies up as they go, leaving your home as neat as they found it.

9. Final walkthrough & clean-up

Once the installation is complete, the installers will clean up the work areas, leaving your home tidy and free of debris. You’ll receive a walkthrough on how to properly operate and maintain your new windows, ensuring you get the most out of your investment. At this time, any remaining payment may also be collected.

10. Post-install support & warranty info

Warranty and support documents for windows

You’ll receive all warranty and support documentation for your new windows, including coverage details, care instructions, and contact information for any issues. A reputable company stands behind their work, providing quality craftsmanship and reliable after-sales service. If you have questions or concerns after installation, you can confidently reach out and expect prompt, helpful support.

11. Enjoy the benefits

Summary

Window installation is a collaborative journey between you and your installation company, built on clear communication, preparation, and trust. By knowing what to expect — from the initial consultation and quote approval to installation day and after-sales support — you’re setting yourself up for success.

Choosing a reputable company with proven expertise ensures your new windows will deliver comfort, savings, energy efficiency and peace of mind.
