Crawl Space Repair in Lincoln, New Hampshire, by Matt Clark's Northern Basement Systems.
Challenge
A homeowner in Lincoln, New Hampshire, reached out to Matt Clark’s Northern Basement Systems after years of dealing with a cold, damp crawl space beneath their home. Every winter, frigid drafts and musty odors would seep up through the floors, making the home uncomfortable and difficult to heat. The fiberglass insulation was sagging, the vapor barrier was torn, and moisture was taking its toll on the wooden support beams. The homeowner wanted a long-term solution that would both stabilize the structure and improve energy efficiency.
Solution
To completely transform and protect the crawl space, the Northern Basement Systems crew installed a combination of proven products designed for long-term moisture control and structural performance:
-
CleanSpace® Encapsulation System: A durable, 20-mil reinforced vapor barrier was installed across the entire floor and walls, sealing out ground moisture and humidity. The bright white liner instantly improved the space's appearance and usability.
-
Closed-Cell Spray Foam Insulation: Applied to crawl space walls, the foam provides insulation and an additional moisture barrier, helping regulate temperature and reduce energy loss.
-
SmartJack® Support System: Galvanized steel SmartJacks were installed to reinforce and stabilize the sagging floor system above. Each jack is fully adjustable, providing long-term structural support and preventing future settling.
Once the work was completed, the transformation was dramatic. The once damp, musty crawl space became a clean, dry, and stable environment. The encapsulation and spray foam insulation eliminated ground moisture and temperature fluctuations, while the SmartJacks ensured solid support for the floors above. The homeowner noticed an immediate improvement in air quality and comfort throughout the home. This Lincoln, New Hampshire project is a perfect example of how Matt Clark’s Northern Basement Systems combines structural reinforcement, insulation, and moisture control to deliver permanent results. By installing the CleanSpace Encapsulation System, SmartJack Support System, and closed-cell spray foam insulation, the homeowner now enjoys a healthier, more energy-efficient home — with a crawl space built to last for decades.
