Replacing doors and windows is one of the most important investments you can make to improve your home’s comfort, energy efficiency and value. In Greater Montreal, where temperature fluctuations and freeze-thaw cycles put buildings to the test, choosing the right products and ensuring proper installation can have a significant impact on your home’s long-term performance.
Whether you want to modernize the look of your home, reduce heating costs or replace windows that have become less efficient over time, several factors should be considered before making a decision.
At Portes et Fenêtres Verdun, we have been helping homeowners across Greater Montreal since 1967. Our experience allows us to recommend solutions suited to Quebec’s climate, each family’s needs and a wide range of budgets.

1. Prioritize ENERGY STAR® Certified Doors and Windows
Energy efficiency has become an essential consideration when replacing doors and windows. ENERGY STAR® certified products meet performance criteria designed to help reduce heat loss. To better understand the different performance indicators, learn more about windows and energy efficiency.
In Quebec, where heating accounts for a significant share of residential energy use, high-performance windows can help maintain a more stable indoor temperature, reduce drafts near openings and lower heating and cooling needs.
Window technology has evolved considerably in recent years. Low-emissivity (Low-E) glass, argon-filled sealed units and high-performance spacers can now deliver significantly better performance than many windows installed fifteen or twenty years ago. Our window buying guide explains the main technical criteria in greater detail.
For homeowners planning to replace their windows in Greater Montreal, choosing energy-efficient products is generally a worthwhile long-term investment.
2. Never Underestimate the Importance of Installation
Even a high-performance window can lose part of its efficiency if it is poorly installed. Improper installation can lead to air or water infiltration, moisture problems, condensation and a shorter lifespan for certain components.
A specialized team has the knowledge required to work with different types of buildings, whether it is a century-old home, a Montreal duplex or a recent construction.
A professional door and window installation helps ensure proper sealing around openings and maximizes the performance of the products selected. It can also help ensure compliance with manufacturer warranty requirements.

3. Compare Several Manufacturers Before Making a Decision
Today’s door and window market offers a wide range of materials, styles and performance levels. Choosing solely based on price can sometimes mean compromising on durability, energy efficiency or comfort.
A company that offers several product lines can help homeowners identify a solution that truly matches their needs.
Some homeowners prioritize energy efficiency, while others place greater importance on soundproofing, maintenance, design or budget.
Taking the time to compare different options generally makes it easier to find the right balance between performance, appearance and price. For a more detailed comparison, read our guide on which type of window to choose.
4. Take Advantage of an In-Home Consultation
Every home has its own characteristics. An in-home consultation makes it possible to consider factors such as the home’s orientation, sun exposure, existing openings and specific features of the building.
The visit also gives homeowners an opportunity to speak directly with an advisor, better define the project’s needs and receive recommendations suited to the property.
For many Greater Montreal homeowners, this personalized approach simplifies the process and makes it easier to understand the available options before making a decision.
5. Invest in Durable, High-Performance Materials
Doors and windows are designed to last for many years, so it is important to choose materials suited to Quebec’s climate and to the level of maintenance you are comfortable with.
PVC remains a very popular choice thanks to its insulating properties, durability and low maintenance. Hybrid windows, which generally combine PVC and aluminum, are also an attractive option for homeowners looking for a balance between performance and aesthetics. Explore the different door and window materials and their characteristics.
Beyond the frame material itself, the quality of sealed glass units, opening mechanisms and hardware also plays an important role in a window’s long-term durability.
6. Review Warranties Carefully
A good warranty is about more than the number of years advertised. It is important to understand exactly what is covered and which conditions apply.
Some warranties may be prorated, while others provide more complete coverage or can be transferred when the property is sold. You can review the current Verdun Warranty to learn more about the protection offered.
It is also important to consider the stability of the company you are dealing with. A long-term warranty is most valuable when it is backed by an established company that can continue to provide after-sales service for years to come.
7. Consider the Financing Options Available
Replacing several doors and windows can represent a significant investment. Depending on the size of the project, financing solutions can make it possible to spread payments over a more manageable period.
This can allow homeowners to complete the work at the right time instead of postponing the replacement of products that have become less efficient. Portes et Fenêtres Verdun also offers financing options with Financeit.
Before choosing a financing option, it is important to compare the terms offered and consider the total cost of the project.
8. Check Your Municipality’s Regulations
Before choosing new doors or windows, check the regulations that apply in your municipality. Depending on the property’s location and the nature of the work, certain changes may require a permit or be subject to specific requirements.
This is especially relevant for certain heritage buildings or neighbourhoods, where rules may govern the appearance, dimensions or other characteristics of doors and windows. Your choice of window type should therefore also take any applicable municipal requirements or restrictions into account.
Checking the applicable requirements before ordering your products can help avoid changes, delays or additional steps once the project is underway.

9. Work With an Established Company
Experience is an important factor when choosing a door and window contractor. An established company generally has a stronger understanding of local buildings, regional climate conditions and the products available on the market.
Since 1967, Portes et Fenêtres Verdun has been helping homeowners across Greater Montreal with their door and window projects.
In addition to working with several Quebec manufacturers, Verdun operates its own manufacturing facility in Saint-Bruno. This combination allows us to offer a range of options and support homeowners from product selection through installation.
10. Think About Long-Term Value
Replacing doors and windows is not only about improving the appearance of a home. It is an investment that can affect everyday comfort, sound insulation, energy efficiency and property value.
Price is obviously an important factor, but it is best to evaluate the project as a whole: product quality, energy performance, installation, warranties and durability.
By choosing products suited to your property and Quebec’s climate, you can enjoy a more comfortable and efficient home for many years.
A personalized consultation with a Portes et Fenêtres Verdun advisor can help you explore the available solutions, compare options and obtain an estimate tailored to your project.
