It’s usually too small to be seen as valuable and most people dread going into their crawl spaces because they are often damp and dark spaces that are so low they hurt your back.

Job Stories From Gilford, NH
Crawl Space Vapor Barrier and Support in Gilford, New Hampshire

Tom of Gilford, New Hampshire was in search of a permanent solution for his dirt crawl space with some water damage. He found Northern Basement Systems online and called to book his FREE ESTIMATE

We then provided Tom with the best solution for his crawl space to ensure that it remained dry, clean, and warm. First, the installation specialists placed 2 adjustable SmartJack Supports to add supplemental support to the home. Next, the installation team laid down CleanSpace Drainage Matting and CleanSpace Liner. This CleanSpace Crawlspace Encapsulation System will keep any debris or water from entering the crawl space area year-round. Next, our team sprayed closed-cell polyurethane foam 3" thick on the perimeter walls. The foam was then painted with intumescent paint to meet fire code regulations. Lastly, the installation team installed a SaniDry Sedona Dehumidifier to improve air quality and reduce humidity. 

With these systems in place, Tom's home is now safer, cleaner, and warmer. Don't wait to fix your basement or crawlspace! Call Northern Basement Systems at 855-DRY-TIME to book your FREE ESTIMATE!

We just had a flood in the basement. We realized the drain from the sub pump was clogged and cleared it. We are having issues now with water seeping in now on one side. But when there's heavy rain it seeps in multiple area. We run dehumidifiers yearly and would like to just take care of the problem if it's possible to.
