Systèmes Sous-sol Québec Before & After Photos

Before the work began, the home's low-clearance crawl space was only about 26 inches high, making it difficult to access and inspect. The wood construction required additional structural support, and the homeowner wanted to reinforce the area with properly installed support piers while also addressing moisture concerns. After installing SmartJack® support posts, galvanized steel beams, Beam Splice components, CleanSpace®, Drainage Matting, SmartSump®, StarPipe™, and a SaniDry™ Sedona dehumidifier, the crawl space now benefits from improved structural support and comprehensive moisture control. The upgraded system provides a stronger foundation beneath the home while helping keep the crawl space drier and better protected year-round.

In Notre-Dame-Des-Bois, a homeowner was facing a serious problem with his crawl space. The area was damp all year round, and the constant moisture had created an environment conducive to the spread of mold and foul odors throughout the house. The wooden joists supporting the floor were softening and beginning to rot, causing the floor above to sag and become uneven. The moisture also attracted pests and insects, while the cold, damp air made the upper floors cold and uncomfortable in winter. In addition, the crawl space was unusable for storage due to water damage and rust on metal components.

To put an end to these problems, our team installed our CleanSpace® encapsulation system, a thick, durable vapor barrier that completely seals the crawl space. To remedy the weakening of the floor structure, we added the SmartJack® support system. These adjustable steel supports were installed on a stable base to raise the sagging floors and permanently reinforce the joists against further damage.

Now the crawl space is clean, dry, and protected, with no risk of mold, pests, or wood rot.

In Saint-Romain, the client was facing a significant issue with an aging and inefficient sump pump that was no longer able to properly evacuate water during heavy rainfall, increasing the risk of water accumulation and basement infiltration. The situation was also critical due to the lack of a backup system in case of a power outage, which greatly reduced the reliability of the drainage system. We therefore carried out a full replacement of the existing system with a much more efficient solution by installing a TripleSafe system, which combines a primary pump, a secondary backup pump, and a battery-powered system to ensure continuous operation even during power failures or heavy water loads. This upgrade significantly improves basement protection, foundation water management, and overall building safety, while providing a durable solution adapted to Quebec’s climatic conditions.

In Sainte-Marie, the owner was facing a persistent moisture problem in his crawl space, a situation that was causing mold, unpleasant odors, and concerns about the structural integrity of his home. The humid air was spreading throughout the rooms, affecting comfort and quality of life inside. To permanently solve this problem, our team intervened with our CleanSpace system, a comprehensive and durable solution. We installed a CleanSpace membrane to effectively seal the floor and walls against moisture, added SilverGlo insulation to improve energy efficiency, and integrated the CleanSpace drainage matting to redirect water and prevent future accumulation. The result has literally transformed the crawl space into a clean, dry, and well-insulated area, protected from leaks and odors. Thanks to this intervention, the house is healthier, more comfortable, and better protected for years to come.

In Saint-Honoré-De-Shenley, a homeowner was dealing with water seeping into their basement. Their aging French drain had stopped doing its job, allowing moisture to collect and linger. Each rainfall brought more stress, and the basement was no longer a reliable, usable part of their home. After contacting Systèmes Sous-sol Québec, the homeowner received a customized waterproofing solution featuring WaterGuard, SuperSump, and IceGuard. Our team installed a system designed to discreetly capture and remove water, even during freezing temperatures. The basement is now clean, dry, and protected year-round—restored as a valuable part of the home and no longer a source of worry.
