Why Do New Hampshire Basements & Crawl Spaces Get Wet?

Flooded basement: Being in New England, New Hampshire experiences the heavy spring rains, the thunderstorm-filled summer months, and the snowy winter season. All of the following can easily cause flood issues for your home's basement. Before waiting for the next big storm to come and go, make sure your basement is prepared to take it on. 

Other wet basement signs: There are many possible sources for pooling water, damp basement walls or flooring, and high humidity. These include: rusty basement windows, poor grading around the foundation, leaks through cracks in the foundation, saturated soils, simple plumbing failures, and poorly functioning drainage or sump pump systems. A basement already musty and damp is ill-prepared for the next bad rainstorm! Basement waterproofing can address the underlying issues, prevent future water damage and improve the indoor air quality.

    Customer Testimonial

              Justin did a superb job in every way, removing my very old dehumidifier and replacing it with a new one. He arrived promptly, after calling about half an hour before hand. He tested the old unit thoroughly and we discussed why it needed to be replaced. Justin also offered to take a look at my old sump pump, then provided lots of information about how it was functioning and when it might need further attention. He answered every one of my questions thoroughly and patiently. He inspired real confidence with his intelligence, knowledge, and articulate explanations. Throughout the visit, Justin was affable as well as professional. A+ in every way.

    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.
