Crawl Space Repair Contractors in New Hampshire

Your New Hampshire crawl space is a key to your home’s health. If your crawl space begins to rot, grow mold, or experience structural problems, this has the potential to extend to every part of your house.

Many homes in New Hampshire have dirt, vented or unconditioned concrete crawl spaces. This can be very detrimental to homes because moisture vapor and high humidity in the soil moves easily from the dirt into your crawl space and then into the rest of the home. Moisture ruins houses by providing a hospitable environment for mold, fungi, and insects that destroy wood framing. Crawl space moisture, and the mold and mildew that thrive in this environment, affect not only the floor system directly above, but also the entire house.

CleanSpace Crawl Space Encapsulation System

The CleanSpace system completely isolates your home from the earth, dramatically reducing the humidity level in the air and, in some cases, eliminating mold growth, rot, and critters from your crawl space. It not only makes the entire house healthier, but also makes it more energy efficient.

Basement Systems, Inc has dealers who install the CleanSpace System throughout New Hampshire, offering, Crawl Space Insulation in New Hampshire, including Berlin, Concord, Dover, Keene Lebanon, Manchester, Portsmouth and any surrounding areas.

Call us toll-free at 1-800-638-7048 or contact us online to schedule a FREE inspection and estimate.

    I thought the work to install the system was outstanding. The only thing I think could be improved is the finish work. rough cement work and an old piece of wood to support the sump pump drain pipe.
