A team of passionate professionals dedicated to protecting your real estate investment.

Founded by Antoine Gagnon and Simon Leduc, partners since 2021, Fondations Gagnon Leduc was born from the desire of two dynamic young entrepreneurs to revolutionize the foundation repair industry in the Montreal area. With solid technical expertise and a commitment to excellence, our team quickly distinguished itself through the quality of its work, professionalism, and customer satisfaction-focused approach. Today, we are proud to have become a reference in crack repair, waterproofing, and drainage.
This academic foundation, combined with their field experience, enables them to conduct efficient, safe, and impeccably executed projects.
Guided by a shared vision, Antoine and Simon place quality, durability, and customer satisfaction at the heart of every intervention. Their synergy, complementarity, and commitment to excellence are reflected in both their teams and the results delivered to their clients.
Today, Gagnon Leduc stands as a trusted partner for foundation work.

Fondations Gagnon Leduc is proud to be a CAA-Québec Approved Contractor, a distinction that attests to our reliability, the quality of our work and our commitment to customer satisfaction.
To be recommended by CAA-Québec, we submit to a rigorous selection process and to ongoing monitoring of our service quality. By choosing a CAA Approved Contractor, you get the peace of mind of a partner recognized for its professionalism and integrity.
