Expand Your Living Space With Confidence With Our Verified Experts

A New Chapter for Your Property, in Trusted Hands

Whether your family is growing or you simply dream of having more room to breathe in your everyday life, a home extension is one of the best ways to transform your current property without dealing with the inconvenience of moving.

However, this type of major renovation involves nearly every aspect of construction. From excavating new foundations and building the structural frame to repairing or extending the roof, coordinating the work requires flawless technical expertise.

Finding the right general contractor to manage a project of this scale can quickly become a source of stress for homeowners. Our platform is specifically designed to eliminate that uncertainty and simplify the process.

We connect you directly with professionals recognized for their rigorous project management, helping you create a safe and comfortable new living space while reducing the risk of unpleasant surprises and construction defects.

A home extension is a major project that requires careful planning, from assessing your architectural needs to obtaining all required permits. To learn about every crucial stage of the process and help ensure the success of your project, read our detailed checklist: Home Addition or Extension: Your Go-To Project Checklist

A Verified Network in Quebec and Across Canada

To provide you with a smooth and highly secure experience, our service quickly connects you with three qualified contractors ready to take charge of your home extension project.

In Quebec, every general construction company must complete a rigorous screening process before joining our exclusive network. We systematically verify that each contractor holds a valid licence issued by the Régie du bâtiment du Québec, or RBQ. We also confirm the company’s legal corporate status, verify the absence of criminal records or professional disputes, and carefully review its history of customer feedback. In addition to an RBQ licence, a home extension contractor may need other qualifications and authorizations, such as a CCQ competency certificate and municipal permits.

The same high standard of protection applies to homeowners in other regions of the country. Our selection criteria are adapted to local regulatory authorities, particularly in Ontario, Alberta and British Columbia. This gives you greater confidence that the professionals entering your home are trustworthy and committed to complying with applicable building codes.

Frequently Asked Questions About Home Extensions

What Factors Influence the Scope of a Home Extension Project?

Several technical factors must be carefully evaluated when planning your extension.

Your municipality’s zoning regulations, the structural condition of your current home and the accessibility of your property will all affect the architectural options available to you.

Whether you are considering a side addition, a second-storey extension or an addition supported by helical piles, the complexity of the structural work and your choice of finishing materials will directly influence the overall scope of the project.

Having these factors assessed by a qualified general contractor is one of the best ways to develop a realistic plan and avoid unexpected complications.

To explore all the elements that should be considered before having your plans prepared and to determine whether an extension may be more advantageous than moving, read our complete guide: Home Extension or Addition - How to Gauge Budgetary Needs?

Why Is It Essential to Hire an Architect or Architectural Technologist for a Home Extension?

A residential extension requires thorough technical and architectural planning.

The expertise of a certified professional is essential for confirming the structural feasibility of your ideas, preparing accurate plans and reducing the risk of having your permit application rejected by the municipality.

In addition to helping ensure the strength and safety of the new structure, these professionals optimize the space and design so the addition blends seamlessly with the existing building.

Their involvement helps support a well-coordinated construction process from beginning to end.

To learn how these professionals can turn your vision into reality and better understand the differences between their respective services, read our specialized guide: Home Extension Architect – What You Need to Know

What Are the Benefits of Choosing Helical Pile Foundations for a Home Extension?

Helical piles are an excellent alternative to traditional concrete foundations for supporting a new ground-level room, sunroom or lightweight extension.

This method requires minimal excavation, helping preserve the appearance of your yard and reducing the need for heavy machinery that could damage the property.

When installed by qualified professionals and securely anchored below the frost line, steel helical piles provide excellent structural stability during demanding seasonal freeze-and-thaw cycles.

Because there is no curing or drying period, carpentry work can begin shortly after installation, allowing the project to move forward efficiently.

To learn more about the engineering requirements, compatible types of extensions and whether this foundation method is suitable for your property, read our complete guide: Home Addition on Piles in Quebec: Guide and Prices
