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

Founded in 2018 by Antoine Gagnon and Simon Leduc, 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 both landscaping projects and foundation work.
