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.

    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.

    As a business woman it is very important for me to have consistency and reliability between employees and management. My experience with Erickson has been tremendous, from management to the crew out here everything has been perfect. Even with finding multiple different issues with my house they were able to get it all figured out for us! The communication and dependability I've received from this company has been a great experience and much better than prior contractors in past! Nick and Crew not only worked very hard but kept us in the loop letting us know everything that came up and how the job may progress. I'm so happy I found a company and crew that took care of us like they truly cared about the outcome of our job. Can't put it into words besides so thankful for Erickson's help!

    It is so refreshing to work with a company that does very good work and then backs up their work if a problem arises. The work done back in July to remedy the water problem has completely transformed my basement from a wet and damp useless area to a nice dry area that is both useful and a place that we want to spend time. I have lived in this house for 30 years and I never had a basement that could be used for storage or just to go work on a project in the colder months and now I have it! Additionally, knowing that my house is properly supported is also comforting and will add to the value in the long run. Each person I have interacted with through this entire process has been professional and customer focused. It is nice to see your 60 second weather ad on the morning news and think to myself "I am glad I called these folks". Your entire team is AWESOME!

    Erickson recently completed a major basement project for us and the work was superb. Unconditionally recommended! The company worked closely with us to design a solution that went far beyond our expectations and maximized our dollars. Our 135 year old home now has a beautiful basement space with new structural SmarttJack columns, a proper concrete slab floor, expanded headroom through a partial lowering, sealed walls and a comprehensive radon remediation system. The entire crew was professional, knowledgeable and courteous. Chris (representative), Nate (project manager), Scott and Chris (crew foremen) and all the hard-working crew that took such pride in their work impressed us from start to finish. Well done!

    We had a crew of four perform installation of an interior perimeter drain and window well ducts over two consecutive days in April 2022. The crew consisted of Anthony Rivas (foreman), Melvin Hidalgo, Justin Gouthier, and George Gouthier, all were conscientous and pleasant. They arrived at the time promised each day. Anthony answered our numerous questions and made us as comfortable as possible especially in light of the invasive nature of jackhammering the concrete floor of our basement, etc, his explanations were very helpful. We also found our dealings with office staff (thanks Nicki, Kim, and Cassidy!) to be great! Good company to deal with!

    "I wanted to take a moment to thank you all for the hard work which has gone into my basement this past week. I am aware that climbing into dimly lit and poorly ventilated concrete slab for jack-hammering, is not the most glorious work. I commend Daryn, Steve, and Danny for doing this without a complaint. Their professionalism, execution, and quickness of work was pretty amazing considering the laborious task they were undertaking. Likewise, I would like to thank Jamie in the office for helping to ease us through this process, and Kevin for beginning the whole job. We are looking forward to working with your company and especially Matt in the garage, as he also demonstrated a high level of professionalism when he and Brandon were here."
