Crawl Space Repair in Chazy, New York, by Matt Clark's Northern Basement Systems.
Challenge
A homeowner in Chazy, New York, noticed sloping floors on the first level, musty odors after rainy weather, and increased humidity throughout the home. The crawl space had open earth, seasonal water intrusion at low points, and several aging wood support posts showing signs of compression. Fiberglass batts were sagging from the joists and had absorbed moisture, worsening air quality and energy costs.
Solution
A Certified Crawl Space Specialist performed a complete evaluation of the crawl space. Several wood supports had begun to compress and settle, causing noticeable floor deflection above. Water staining and elevated moisture levels indicated that the crawl space had previously experienced standing water. Wet insulation and unsealed vents allowed humid outdoor air to enter, worsening conditions. The rim joists were unsealed, creating energy loss and airflow pathways for moisture and odors. A permanent solution was needed to stabilize the structure and control moisture.
To permanently stabilize and protect the home, the Northern Basement Systems crew installed a complete crawl space repair system:
-
SmartJack™ Support Posts were installed on engineered footings to lift and support sagging beams and joists, correcting floor unevenness and preventing future settlement.
-
CleanSpace® Vapor Barrier System was mechanically fastened and sealed to encapsulate the crawl space, providing a durable moisture barrier and clean, bright surface.
-
SmartDrain™ with Built‑In Alarm was installed beneath the encapsulation layer at the lowest point of the crawl space, allowing drainage of plumbing leaks and providing early‑alert protection.
-
SaniDry™ Crawl Space Dehumidifier was installed to maintain ideal humidity levels, improve air quality, and protect wooden structure members from moisture‑related damage.
The floors above were stabilized, and they felt noticeably firmer and more level. The crawl space is now clean, dry, and protected from moisture, mold, and odors. The homeowner enjoys improved air quality, reduced humidity, and peace of mind knowing leaks will be detected early. Energy efficiency also improved thanks to the sealed crawl space and dehumidification.
With a SmartJack™ support system, CleanSpace® encapsulation, SmartDrain™ leak protection, and a SaniDry™ dehumidifier, the homeowner received a permanent solution that addressed both structural and moisture concerns. Matt Clark’s Northern Basement Systems delivered long‑lasting stability, healthier indoor air, and a protected crawl space for years to come.
