John reached out to us looking for some waterproofing solutions due to him having a high water table. Upon a consultation with John, we were able to install two Sump Pump Stations, perimeter drainage and a Vapor wall barrier. This helps direct any moisture on the walls into the drainage system and into the sump basin. We also installed two Battery Backup systems to ensure that if he loses power, his pumps will still run accordingly. The installation of a dehumidifier was an important part of this job to help maintain the high humidity level this basement has. John's worry of water flooding his basement during rain storms is now eased and he is happy with the completion of his project.

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!
