Customer contacted us looking for a sump pump installation after other companies had tried to sell them more extensive solutions. We were able to install a sump pump station for them, and they've since informed us that it's working perfectly. They are very grateful that we addressed their specific issue and provided an effective solution, rather than pushing a full waterproofing system. This is a great example of how our approach to customer service can make a real difference.

The sump pump installation was done as a first step of a larger basement remodel project. The job was done quickly, done right, and the team made sure to explain what they were doing and why at every step, including a run through of how the system worked and what to expect once it was in. I have since hired Northeast Basement Solutions to do the full project and am having the same good experience thus far. Highest recommendation

Mark and Miguel are A+ professionals! We used Northeast Basement Solutions for a foundation issue in our new home. They not only came in with a very reasonable quote, they started on the project quickly and took the time to educate us on several things we asked about. They were very responsive and communicated every step of the way. We will definitely be calling them for future waterproofing work. Thanks Northeast!

...We had a dark and moldy basement that is now a bright and clean home gym. They removed all the carpeting, moldy drywall, broken doors, old and broken ceiling lights and old and broken ceiling tiles and replaced everything with new and updated materials. They corrected some old, improperly wired electric stuff and insulated spots that were previously lacking insulation...We'll be enjoying this space as we never have before and are really thankful we were able to work with N.E. Basement!
