Crawl Space Repair Before & After Photos

In Notre-Dame-du-Mont-Carmel, QC, this crawl space was dealing with persistent moisture, musty odors, and poor air quality. The combination of a concrete and stone foundation, along with limited access, allowed humidity to build up, increasing the risk of mold and structural concerns. Without proper drainage or encapsulation, water accumulation and unstable support conditions were impacting both the home’s efficiency and overall health.

The crawl space is now fully transformed into a clean, dry, and healthy environment. With the installation of the CleanSpace encapsulation system, Drainage Matting, and a full perimeter drainage solution connected to the SmartSump system, water is effectively collected and discharged away from the home through the StarPipe system and LawnScape outlet. The IceGuard ensures reliable performance even during freezing conditions. The SaniDry Sedona maintains optimal humidity levels, while the SmartJack system reinforces structural stability. Finished with SilverGlo insulation, the space is now energy-efficient, protected, and built for long-term performance.

In Notre-Dame-du-Mont-Carmel, our team at Systèmes Sous-sol Québec addressed a crawlspace issue involving persistent dampness, musty odors, and clear signs of water infiltration. These conditions not only affected indoor air quality but also posed a long-term risk to the foundation’s structural integrity.

To resolve the issue permanently, a comprehensive solution was implemented. First, a drainage membrane was installed directly on the crawl space floor to capture and divert water as soon as it enters, thereby preventing any accumulation under the house. Next, the CleanSpace system was added on top to create a continuous moisture barrier and completely seal off the space.

SilverGlo panels were also integrated to improve insulation and reduce heat loss. A SuperSump system was installed to ensure constant and efficient drainage of collected water. Finally, StarPipe was added to optimize drainage around the foundation and divert water away from the structure.

Thanks to this work, the crawl space is now dry, stable, and protected against future water infiltration. Systèmes Sous-sol Québec provides comprehensive solutions that combine drainage, waterproofing, and insulation to preserve the health of your foundation.

The main floor in Mr. Hammer's house was no longer level and he even felt his floor "softer" in some places. One of the causes is the lack of support pillars in the crawl space. The current pillars of support were poorly spaced and inadequate.

The solution

We added galvanized steel SmartJack pillars to reinforce the beams to properly support the floor joists.These are even adjustable over time.

Before our work began, the crawl space beneath this Herouxville home was damp and unhealthy. High humidity and visible mold were present, raising concerns about indoor air quality and the home’s structural integrity. Poor ventilation and inadequate drainage allowed moisture to build up, increasing the risk of long-term damage.

After installing the CleanSpace crawl space encapsulation system with drainage matting, SmartDrain, and the SaniDry Sedona dehumidifier, the crawl space is now dry, clean, and properly protected. Moisture is controlled, water is safely directed away, and humidity levels are stable. The home now benefits from improved air quality and a healthier foundation environment.
