Northeast Basement was very professional, transparent, and willing to work with us to find the best solution to our basement flooding issues. The team that came was very friendly and clear about the work. And they finished ahead of schedule. Highly recommend!

I have several sump pumps in my basement and all of them are working well except one. One of the pump seems running more than usual. I think something is wrong with that pump. I need someone to come and inspect it.

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!
