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.

    Garnet A. of Beaconsfield, QC

    Customer Testimonial

              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

    Linda-Lyle Aubry of Rosemont-La Petite-Patrie, QC

    Customer Testimonial

              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.
