Job Stories From Conway, NH
Dirt Crawl Space in Conway, NH

Jeff of Conway, New Hampshire had a crawlspace that was poorly insulated and allowing cold air to enter his home during the winter months. Additionally, the dirt floor made the space very displeasing and unusable. Jeff wanted to find a solution to keep the space clean and his home warmer. During his search, he found Northern Basement Systems. We provided him with a FREE ESTIMATE with a site visit and project proposal that would solve all of his concerns! 

Our team installed a full CleanSpace Crawl Space Encapsulation System to lock out moisture, make the space cleaner, and more useable. This system is composed of CleanSpace Drainage Matting to channel any water that attempts to enter and CleanSpace Liner to lock out any moisture or dirt. This encapsulation system is completed with a SmartSump Crawl Space Drainage System to keep the crawlspace dry. In the event of a broken pipe or water leaking through the floors of the home, this drain will pump out that water.

Lastly, our team sprayed 3" thick of polyurethane closed-cell foam around the perimeter of the crawlspace to prevent heat loss. This foam was then painted with an intumescent paint to meet the fire regulation code.

This space is now dry, clean, and warm! Call 855-DRY-TIME to find the best solution for your home!
