Crawl Space Repair Before & After Photos

In Saint-Lucien, a homeowner was dealing with excessive moisture, accompanied by mold and persistent odors in his crawl space. This situation was compromising not only the stability of the foundation, but also the indoor air quality of the house.

To permanently correct these problems, Systèmes Sous-sol Québec deployed a complete remediation and waterproofing solution. The installation of CleanSpace lining, an improved drainage mat, and a SaniDry Sedona dehumidifier effectively controlled moisture and prevented water infiltration. These technologies work together to eliminate mold, neutralize unpleasant odors, and ensure a dry and healthy environment under the house.

Thanks to this intervention, the crawl space is now clean, dry, and fully functional. The owner enjoys improved indoor comfort, lasting foundation protection, and long-term peace of mind. Like many Systèmes Sous-sol Québec customers, he now enjoys a healthier, more protected, and energy-efficient home.

A crawl space is a bad thing for the house. In fact, clay floors are filled with water and transmit water vapors filled with moisture, bacteria, and mold. As the air flows upwards, the air in the crawl space goes to the upper floors of your home, causing you to breathe infected air. In order to solve this problem and make the air in your home healthier, it is important to encapsulate the crawlspace. In order to do do so, we installed our patented CleanSpace vapor barrier membrane. The CleanSpace membrane is composed of 7 layers of treated polyethylene in which an antibacterial additive is added. The membrane is finally treated with an ultra-violet additive in order to extend its resistance and its lifespan as long as possible. Crawl space encapsulation allows this space to be healthier and more useful because you can now use it to store your belongings. All of this gives value to your home!

Faced with a humid, dirt crawl space and sagging floors in Pierreville, QC, this homeowner sought a dependable fix. Notice in the before photo the evident challenges; a mood dampened by deteriorating conditions underfoot. Enter Systèmes Sous-sol Québec. We transformed this beleaguered space into a robust, dry foundation with our SmartJack systems for unwavering support, CleanSpace liner to shield from moisture, and a SaniDry Sedona to maintain dryness. The after photo radiates our dedication to lasting, quality solutions for a secure and comfortable home.

This wet crawl space in Saint-David needed to be stabilized.

The structure of the house got affected after getting exposed to water, and the wooden beams in the crawl space started to deteriorate.

After contacting our company, our team inspected the place and once we got the approval we installed our SmartJacks that are specially designed for crawl spaces. They support and stabilize your foundations and are adjustable to adapt to the movement of the ground.

In Saint-Guillaume, QC, an uninsulated crawl space was causing floor movement and instability in the support beams, due to moisture infiltration clearly visible in the first photo. The excess humidity had begun to compromise both comfort and structural integrity.

To resolve the issue, Systèmes Sous-sol Québec installed a complete CleanSpace® Encapsulation System, paired with CleanSpace™ Drainage Matting. As shown in the ‘after’ photo, this custom solution created a sealed, durable environment that prevents moisture from entering and damaging the space.

To further enhance protection, we added the SmartDrain™ system, designed to detect plumbing leaks beneath the liner. If a leak occurs, it redirects water safely while sounding an alert—providing early warning and peace of mind for the homeowner.

This tailored approach not only stabilized the crawl space structure but also safeguarded the area against long-term moisture issues. The result is a clean, dry, and resilient foundation that helps preserve the home’s value and comfort for years to come.
