Your Home faces Water Damage

1. As the snow melts and the rain falls flash flooding near your home can become a serious concern.

2. When flooding hits your area, your basement is most likely to be the prime target for water damage.

3. If you allow it to be wet, moldy, humid, smelly, and unhealthy, you're abandoning an entire floor of space in your home. Additionally, the basement air - filled with odors, dust mite feces, humidity, and mold spores - will rise into the rest of the house, ruining the healthy environment of the home.

Quebec's Trusted Waterproofing Company

  • "My experience with Systèmes Sous-sol Québec has been excellent." Read Full Testimonial

    Daniel C. of Ahuntsic-Cartierville, QC

    Customer Testimonial

              The problem I had fixed was with one of my dwellings. I have a three and a half that is a short basement, and it had water infiltration. One of the walls was starting to show cracks.In theory, there was supposed to be a French drain on the outside, but I never dug the outside earth around the house. In other words, I have a swimming pool on the outside, a deck that occupies part of the backyard, so we would have had to demolish everything to enter the equipment in order to access the French drain.When I went to the home show, I saw this was a professional company that offered solutions adapted to the type of problems I was facing. The company was specialized in crawl spaces, which was my case, and in basement water infiltration, specifically. What I liked is that we were able to find, with the WaterGuard system, the ability to install a French drain as there was water infiltration, from the inside of the house rather than do it from the outside.As for my level of satisfaction, if I have a neighbor or friend who mentions they have similar water infiltration problems and who need a solution, I will not hesitate to recommend Systèmes Sous-sol Québec.The company is very professional, a quality service from finding the solution and selling it to the execution of the work.The work went very well, the team was very professional. They were meeting with me from time to time during the days when the work was being done and giving me explanations during the different stages. I was looking for a company that was specialized in this kind of problems.Do a solution that would last very long. When I will sell the house, the warranty is transferable. My experience with Systèmes Sous-sol Québec has been excellent.There is a lifetime warranty that is offered with it.

    Daniel C. of Ahuntsic-Cartierville, QC

    Customer Testimonial

              Ayant eu une infiltration d’eau dans son vide sanitaire, on lui avait recommandé d’installer un drain français, ce qui était impossible avec le deck et la piscine creusée dans la partie arrière de sa cour. Nous ayant rencontré au salon de l’habitation, M. Cleroux nous a demandé d’inspecter sa maison. Nous lui avons proposé par la suite une solution qui convenait à ses besoins avec un drain intérieur WaterGuard, au lieu de creuser de l’extérieur pour poser un drain français. M. Cleroux a été impressionné par notre professionnalisme, par la qualité du travail et les garanties transférables que nous offrons ainsi que par notre désir de travailler avec lui tout au long de la durée des travaux. Enfin, il nous raconte qu’il n'hésiterait pas de recommander notre compagnie à un ami ou à un voisin.

    Customer Review

    By Jacques D.
    Brossard, QC

    Le problème d'humidité et de dommages de surface était tout simplement du à une fissure et ne nécessitait pas de drain et de pompe car la dalle de béton était intacte. Toutefois il faut souligner la courtoisie et l'efficacité des ouvriers. M Marcel Perreault nous a fait une belle présentation de la compagnie et du produit même si la solution envisagée au départ n'était pas la bonne. Il ne pouvait pas savoir sans ouvrir le mur. Nous attendons un remboursement de la différence de coût et aurions aimé obtenir le rabais de 5% consentis au préalable . Merci pour les bons services et penserons à vous à l'avenir.

    It's been a week since Basement Systems has transformed our basement - the system is amazing - not a drop of water to be seen, even during the Spring thaw. We are more than pleased at the results so far, and the look of the cleanspace on the walls and floor is fantastic. Great job!

    From beginning to completion, we found the service very professional and friendly. Peter, the sales representative, was very friendly, efficient and knowledgeable and the presentation and discussion regarding our problems was well understood by my husband and me. We found the solutions presented to us made sense. There was no pressure from anyone to choose your firm. Subsequent to our agreement to have the work done, the appointment was made and the work team showed up on time. They were hard-working, efficient, very polite and professional. The repairs were done within a day and a half, as promised and they left the basement and garage in good order. The work was completed yesterday and we are confident that the repairs will stand the test of time.

    Customer Review

    By Anthony M.
    St Leonard, QC

    The only thing was that the job was a little more difficult for the installers than thought of at first. The actual finishing around the doors and electrical lights were much more difficult because of the small space and the rigidity of the original material, but the guys also worked it out. Also they did a great clean up job.
