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.

    Hi Andrew, I just wanted to give you an update on our basement. People love to give bad news, but I want to give you good news. There is not a drop of water in the basement this year and we have probably had the worst spring on record. I don't know if you remember the job, but your team put in an interior french drain around 3/4 of my basement and dug the sump pit about 1 foot deeper. The interesting part is that there has not been a drop of water in the interior french drain. It seems like digging the sump pit deeper was all that was necessary. Water is pumped out into my front ditch before it ever gets high enough to get into the drain. Now, I can finish my basement with confidence. Thanks for your help. Garnet

    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.

    Bonsoir Nelson xxxxxx , Systèmes sous-sol Québec est une compagnie que je peux recommander les yeux fermées. J'ai fais faire des travaux il y a 3 ans et j'ai été ravi non seulement sur le moment mais encore plus aujourd'hui quand je vois la durabilité. De plus que ce soit Michel le propriétaire ou Antonio qui est le représentant avec lequel j'ai toujours été en contact, ce sont des personnes de confiance et très intègres. Lorsqu'ils disent qu'ils peuvent ou vont faire ceci ou cela, "delivery exceeds expectations". C'est un drôle de hasard mais j'ai signé aujourd'hui un contrat de près de 20K pour des travaux d'assainissement dans un immeuble locatif que je possède... cela est pour vous dire à quel point je suis satisfait de leur travail il y a qques années, de leur service et de leur professionnalisme. Si vous voulez en discuter plus en détails, vous pouvez me rejoindre au xxxxx. Samuel xxxxxxx

    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. "
