Who is Systèmes Sous-sol Québec?

Since 2007, Systèmes Sous-sol Québec has made the homes of thousands of customers healthier, safer and more comfortable with proven solutions for wet basements, damp crawlspaces and cracked foundations.

We are a member of APCHQ and ACQ, and are CAA-Quebec Approved for our skills, credibility and reputation.

We were voted as Canada's # 1 dealer at the 2018 Contractor Nation Convention and we are the 2019 and 2020 recipient of the prestigious Consumer Choice Award in the category “Foundations – Replacement and Reinforcement” for the Greater Montreal area. Systèmes Sous-sol Québec first began in 2007 and has continued growing ever since!

The company started when the founder, Michel Haydamous, decided basement waterproofing and foundation repair was just the industry he was looking for.

Fast forward to today and we still begin each day with our mission: "To grow our lives and business with a winning team that consistently delivers the best for our customers".

We know how difficult it could be for homeowners to find a responsible, trustworthy contractor, but Systèmes Sous-sol Québec is working to change that. Excelling in quick customer response, free estimates, and above all, quality, integrity, and peace of mind, are just some of the things we provide to guarantee the 100% satisfaction of our customers.

We stand behind our warranty and work hard to give our customers everything they deserve and much more.

We are part of the largest waterproofing and foundation repair networks in North America, Basement Systems and Supportworks, with hundreds of dealers sharing knowledge and experience to have the best solutions and products for foundations and basements. We are proud to bring the best solutions for these services to all the homeowners in our community.

Systèmes Sous-Sol Québec has built a solid reputation for excellence and trust thanks to its expertise in the repair of below-the-grade spaces, and to its qualified teams who offer quality service. Our mission for the next few years is to develop experts and to continue to put forward our values which have allowed us to date to have a reputation for success and expertise in our field.
