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!

Wet basement, would like options to resolve moisture, issues
Vicinity of River Rd in Gilford
I'm at my wits end on repairing this leaky wall in my basement. We've retarred the foundation wall and filled it in properly with piping and stone. The leak follows the length of the chimney along the wall and the footing. We then, regretfully, decided to hydraulic cement the corner. We thought we had it fixed when the water was no longer climbing the wall. It seems like the water is crawling along the floor now after a hard days rain. Not sure how to stop the flow now. I'm hoping to get someone here to give us an inspection to see what our next plan of attack should be.

Need someone to look at basement/foundation which is leaking and give quote
Vicinity of Wild Acres Road in Gilford
I have a 1983 house garage that cracked in 1983 (according to the house inspector that was the town building inspector at the time and decided it was OK --- according to him). The floor has fallen in two of the four corners, both at the side that meets the house. I need to sell my house and I am looking for an less expensive way of fixing this problems. Internet research has led me to you.
