    Customer Testimonial

    Daniel C.
    Ahuntsic-Cartierville, QC
    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.

    Hazel from Windsor Ontario was hit like many people in her area by the 2017 floods. For the first time in 30 years her house was flooded and she needed it to be fixed right away. Hazel had come across many of our Advanced Basement Systems commercial and called right away and was able to get her home fixed. She added the TripleSafe Sump Pump and waterguard to her home and she has not had any flooding since.

    Issue was dirt floor, no insulation, warm moist air wet all the time, mold always a concern. A google search and Advanced Basement Systems came up with the best rating. Called the office and an appointment was booked with Nick. The Inspector came out, inspected the crawlspace, mapped out the project on the spot including a price and gave some options. Initially a partial job was selected, further discussion and sample of product reveled a better option and a complete job was chosen. The use of the material sample provided the homeowner a better sense of the security the job would be done right. Notice the floors are warmer and expect this to translate into energy savings and home comfort improvement. Surprises include the speed with which the job was completed, the conditions of the home and surrounding after the crew left. “Couldn’t even tell they were here, other than the crawl space is beautiful, when they left” “If you want somebody to do the job quickly and efficiently and without hassle, then you should call Advanced Basement Systems.”

    Ce père a découvert des infiltrations d’eau et des dommages dans le sous-sol de son fils dans la Rive-Sud de Montréal. Il a aidé son fils à trouver une bonne compagnie qui aurait une solution adaptée à ce problème. En faisant sa recherche en ligne, il a trouvé beaucoup d’explications sur notre site web et a bien aimé la logique de notre système d’imperméabilisation de sous-sol de l’intérieur. M Ghitescu a trouvé que le système de drain intérieur WaterGuard et les systèmes de pompes de puisard SuperSump et UltraSump étaient ce qu’il leur fallait. Dans cette vidéo, notre client discute de la qualité de la relation qu’il a eue avec les membres de notre équipe dès le début de la procédure. Dans ses propres mots : « Si je trouve quelqu’un qui aurait le même problème, je suis prêt à recommander la compagnie. »

    Linda-Lyle Aubry
    Rosemont-La Petite-Patrie, QC
    Suite aux dégâts d’eau qu’a subi le sous-sol de sa maison centenaire dû à un bris du chauffe-eau, Mme Aubry a appelé sa compagnie d'assurance pour constater les dommages. Cette dernière a réalisé, après avoir enlevé le plancher, qu'il y avait une infiltration d’eau au niveau de la fondation et ne pouvait donc payer pour les réparations des dégâts d’eau que si le sous-sol était complètement imperméabilisé. Après avoir rencontré 2 compagnies sans être convaincus que les solutions règleraient leur problème, Mme Aubry et son conjoint se sont tournés vers l’internet et ont trouvé Systèmes Sous-sols Québec. Comme nos clients ne voulaient pas embarquer dans de grands travaux, notre système de drainage intérieur WaterGuard était une solution parfaite, puisqu’ il remplaçait complètement le drain français, et leur permettait donc d’éviter de grands travaux d'excavation dans leur cour nouvellement aménagée. Un autre grand avantage avec notre compagnie était la garantie à vie que nous offrons pour le drain, en comparaison avec les autres entrepreneurs en étanchéisation des sous-sols qui ne leur ont offert que des garanties de 10 ans. Mme Aubry et son conjoint ont très aimé l'approche de tout notre personnel : de la confiance qu’a émané notre spécialiste Jorge en agissant comme conseiller plutôt que comme vendeur, à l’empathie et l’esprit de toute l’équipe, le respect de leurs présence, valeurs et environnement. Dans ses propres mots Mme Aubry nous racontait qu’« Il y avait vraiment une belle conscience professionnelle de tous les ouvriers qui sont venus ici". Mme Aubry a tellement apprécié le service de notre équipe qu'elle a trouvé « qu’ils avaient un esprit familial puis qu’[elle] faisait partie de la famille". Enfin nous sommes très contents d’avoir pu répondre aux besoins de Mme Aubry et de sa famille, et de rendre son sous-sol habitable.

    Customer Testimonial

    Nick I.
    St. Leonard, QC
    After ten years living in his home, Nick I. from St. Leonard, Quebec noticed that the basement started to leak, probably because of an extension that was built without proper drainage. He called a few companies in the area for an estimate, but only Basement Systems Quebec offered a complete solution that made sense to him for a number of reasons. First it wouldn't require digging out the foundation from the outside or a lot of excavation from the inside. Installing the exclusive WaterGuard system offered by the company would only require jack hammering a six inch trench along the interior perimeter of the basement walls. The system was also more affordable, but it was the sump pump system with alarm and a battery backup, and the Transferable Lifetime Warranty offered by the company that really convinced Nick that he had the right company and the right products for the job. "Overall we are very satisfied. If someone would come to me and ask me for my advice, without hesitation I would strongly recommend Basement Systems Quebec, because their problems would be solved, they could be assured that there wouldn't be any more water coming into their house, and the service that they would provide would be very good, and they could have the confidence that their are reliable." - explains Nick. "We paid less than we would have paid if we went with another supplier but the work was actually done well and we haven't had a problem ever since. "

    Eva & Jeff P.
    Notre-Dame-de-l'ÃŽle-Perrot, QC
    Eva and Jeff Parry, residents of Notre-Dame-de-l’Île-Perrot, QC, had dirt crawl space that was very humid because of the soil and the water infiltrations. Mold started to appear on walls and floors. They knew they had to fix this issue because their daughter Jessika had a terminal condition called Spinal Muscular Atrophy type 1 so the Parrys had to do everything they could to improve the air quality that was badly affecting her breathing and respiratory system. Our team went and fixed this problem by fully encapsulating the crawl space by installing a vapor barrier membrane, a crawl space interior drain, a sump pump system and a powerful dehumidifier system. In this video, the family discusses their experience with Systèmes Sous-sol Québec and the impact of the encapsulation on their daughter’s health.
