Crawl Space Repair Before & After Photos

In Sainte-Sabine, a homeowner wrestled with a crawl space filled with moldy beams and constant moisture. At a height of just 3–4 feet, effective encapsulation was crucial. In the "before" photo, you can clearly see the signs of ongoing moisture issues contributing to mold growth and poor air quality.

To begin the transformation, our team applied Mold-X2 to treat and neutralize the mold on wood surfaces, helping restore a healthier environment. We then installed the CleanSpace® system, fully encapsulating the area to block out ground moisture. CleanSpace™ Drainage Matting was laid beneath the liner to direct any water efficiently toward the drainage path. To detect and handle potential plumbing leaks, a SmartDrain™ system was added; offering peace of mind through its built-in alarm and smart drainage redirection.

For improved energy efficiency and year-round dryness, we also installed SilverGlo™ insulation along the crawl space walls.

In the “after” photo, the crawl space is completely transformed; clean, dry, and mold-free. This solution not only protects the home’s structure but also supports healthier indoor air and better energy performance.

In Saint-Cyprien, our client was dealing with a damp crawl space, with soggy soil, persistent odors, heavy air in the house, and a real risk of mold, wood deterioration, and problems related to excessive moisture. The space contributed to increased indoor humidity, affecting comfort and air quality.

To remedy the situation, we first installed a drainage membrane on the floor to capture water from the ground and efficiently direct it to the drainage point. Next, we completely encapsulated the crawl space with CleanSpace membrane, creating a waterproof barrier against moisture, water vapor, and infiltration from the ground. To stabilize humidity levels and improve indoor air quality, we added a SaniDry Sedona dehumidifier, designed to continuously control humidity and reduce the risk of condensation and odors. Finally, a SmartDrain pump was installed to automatically drain water from under the membrane, preventing future accumulation.

Today, the crawl space is clean, dry, and protected, contributing to better energy performance, protection of the home's structure, and a healthier environment year-round. This project demonstrates the importance of a comprehensive approach combining drainage, encapsulation, dehumidification, and active water management for a sustainably sanitized crawl space in Quebec.

High humidity and a weakened beam threatened this crawl space in Saint-Jacques-Le-Majeur, with obvious signs of water damage and mold. Our team at Systèmes Sous-sol Québec tackled the problem head-on after a detailed inspection, installing our CleanSpace encapsulation system to create a durable barrier against moisture. We added the SaniDry Sedona dehumidifier and SmartDrain system to keep the space dry and healthy, ensuring effective water management and long-term protection. The “after” photo shows a transformed, clean, dry, and secure crawl space that protects the structure of the home and indoor air quality for years to come.
