Crawl Space Repair in Hanover, New Hampshire, by Matt Clark's Northern Basement Systems.
Challenge
A homeowner in Hanover, New Hampshire, reached out to Matt Clark’s Northern Basement Systems after noticing sagging floors and a persistent musty odor coming from below their home. Upon inspection of the crawl space, they found damp soil, visible water intrusion, and wooden support beams showing signs of rot and weakness. The home’s floors had developed a noticeable dip in several rooms, and humidity was creating an uncomfortable living environment upstairs. The homeowner knew these issues wouldn’t fix themselves — they needed a professional solution to stabilize the structure and permanently eliminate moisture. A certified crawl space specialist from Northern Basement Systems performed a thorough inspection and quickly discovered several contributing factors. The crawl space lacked a vapor barrier, allowing ground moisture to evaporate into the home freely. The existing wooden support posts were no longer providing adequate support due to rot and shifting soil. Water intrusion from the foundation walls and plumbing lines was also evident, and no drainage system was in place to remove it.
Based on these findings, the specialist designed a comprehensive repair plan combining structural reinforcement, waterproofing, and moisture control — explicitly tailored to the home’s crawl space conditions.
Solution
To restore strength, stability, and dryness to the home, the installation team installed a combination of advanced systems engineered by Supportworks® and Basement Systems®:
-
SmartJack® Support System: Heavy-duty galvanized steel SmartJacks were installed to stabilize and lift the sagging floor system permanently. Adjustable and corrosion-resistant, SmartJacks provide reliable support that won’t shift or settle over time.
-
CleanSpace® Crawl Space Encapsulation System: A durable, 20-mil vapor barrier was laid across the crawl space floor and walls, sealing out ground moisture and creating a bright, clean surface. The CleanSpace system directs any water seepage toward the drainage system, preventing humidity and mold growth.
-
SmartDrain® Drainage System: Designed for encapsulated crawl spaces, the SmartDrain was installed beneath the CleanSpace liner to capture any unexpected plumbing leaks or seepage. The system features a WaterWatch® alarm that alerts the homeowner if water is detected.
After installation, the transformation was remarkable. The floors above were stabilized, the musty odors were gone, and the crawl space was now clean, bright, and dry. The SmartJack system restored the home’s structural integrity, while the CleanSpace and SmartDrain systems ensured a controlled, moisture-free environment.
The homeowner was thrilled to know their home’s foundation was secure and protected — and that they’d never have to worry about damp air, sagging floors, or hidden water problems again. Backed by Matt Clark’s Northern Basement Systems’ industry-leading warranties, this Hanover home is now stable, healthy, and built to last.
