Door and window installation service in the Greater Montreal area
Site preparation
A proper installation starts with accurate measurements. That’s why a technical expert conducts a site visit to validate the production measurements and installation conditions.
Before our installation team arrives, you must clear the areas around the openings—both inside and outside—where the new door or windows will be installed. You will also need to remove blinds, curtains, and other decorative elements. This ensures our workers can do their job efficiently. There should also be enough space to place tools and move around comfortably.
Removal of old doors and/or windows
Before removing your existing doors and windows, the installer will make sure the new products are compliant and ready for installation. The old units will then be removed to make way for the new ones. We will not remove all doors and windows at once, but only as many as can be replaced within a given timeframe. This helps avoid leaving unprotected openings for extended periods and reduces heat loss.
Inspection and preparation of openings
The openings are then inspected to ensure the materials that will receive the new door or window are still in good condition. If everything is in order, we proceed with preparing the openings. If any issues are found, necessary prep work will be carried out.
Looking to have a new door or window installed in your home? Our experienced installers travel throughout the Greater Montreal area to provide professional, high-quality installations. We strictly adhere to the highest industry standards to ensure long-lasting durability, optimal performance, and the success of your investment.
We’ll work with you to determine the best time to schedule your installation, taking into account the estimated project duration and changing weather conditions, which may occasionally require rescheduling.
Contrary to popular belief, door and window installation is possible all year round—even in winter! Thanks to modern installation techniques, your new doors and windows can be installed in just a few minutes, significantly minimizing heat loss.
INSTALLER AT WORK
At Portes et Fenêtres Verdun, installation is part of our turnkey service. When you purchase your doors and windows from us, our trained installation teams ensure your products are installed correctly the first time. It’s the small details and proper planning that truly make the difference. For example, we coordinate with clients to ensure that access to each opening is clear (including snow removal) to facilitate the installers’ work. In some cases, oversized patio doors require on-site frame assembly—so it’s important for the team to have as much space as possible to carry out the installation properly.

DOOR INSTALLATION
Our Portes et Fenêtres Verdun installers travel across Greater Montreal to install all types of doors, including entry doors and patio doors.
Installation
The new door is placed into the final opening from the outside, then adjusted to ensure it is level before being permanently secured. It’s essential to make sure the door is square so that the opening mechanisms work properly and the seals fit tightly for perfect insulation. The key words for a successful installation: level, square, plumb, sealed, and aesthetic.
Insulation and Caulking
Next comes insulation using high-performance materials such as spray foam or mineral wool, along with caulking, to ensure optimal thermal insulation and airtightness. These critical steps are carried out from the inside and/or outside, depending on the project.
Finishing and Site Cleanup
We’ll install the handle and lock, cover the frame with aluminum as needed, and add the finishing trims. After the door installation, we’ll clean up the site, remove all waste and old doors. We’ll also perform a final inspection with you and explain how to operate your new doors.
Don’t hesitate to contact us today after purchasing your door! Our team of expert installers will complete the installation according to the highest industry standards.

Just like with doors, our team is highly experienced in installing windows throughout Greater Montreal including casement windows, awning windows, single/double-hung windows, and sliding windows.
Installation
The new window is placed into the final opening from the outside, then adjusted to ensure it is level before being permanently secured. It’s also essential to make sure the unit is square so the opening mechanisms work properly and the seals fit tightly for perfect airtightness. Key words for a successful installation: level, square, plumb, sealed, and aesthetic.
