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

              I can’t begin to explain how amazing this young man was. I have a finished basement and my sump pumps had failed in the middle of the night. My alarm went off and I was in a panic I was going to flood. I called the emergency phone number at 1:30am and a young man had answered in 2 rings. He seemed wide awake. I told him my problem and he told me he would be there in 1 hour. He showed up before that and was so kind and courteous. He was able to replace my failed equipment right then and there which I couldn’t believe. He even took the time to explain to me the system I had it place. He was such an amazing boy. I can’t begin to explain the peace of mind this boy gave me. I felt so bad for him having to come out at such a late hour knowing he had to work in the morning. Whoever he is I hope he gets to see this review and I hope the company realizes how much of an asset he is.

    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.
