In April 2025, a homeowner who had been quoted large sums by other waterproofing companies for work they were told they needed wrote that Miguel, drawing on 24 years in the trade, said all they really needed was a sump pump — and charged accordingly. That kind of story repeats at Northeast Basement Solutions. The water work is about fixing the actual problem. A March 2026 customer had a french drain system installed as part of a larger job. A 2024 customer had a sump pump with a backup put in and a separate foundation crack filled. A 2023 customer had a sump pump in place before a season of heavy rain and reported it working through it. Another, writing in 2023 after a Christmas Eve storm flooded their basement, was put in touch by a friend. The other half of the business is turning those basements into rooms. In August 2024, a homeowner working to a tight timeline had a basement finished in about two months — an extra bedroom, a full bathroom, a pantry and an entertainment space. A May 2024 customer's dark, moldy basement became a bright home gym once the carpet, moldy drywall, broken doors and ceiling tiles came out. A 2023 customer with a 160-year-old house had the floor dug down for ceiling height and a new concrete floor poured. Dan runs those jobs; Amanda is named repeatedly for keeping schedules on track and answering questions, with Miguel and Mark appearing throughout. Two things to know before booking. Its Better Business Bureau page carries an A- without accreditation, and its Houzz business profile shows as suspended. The company's own site describes basement waterproofing, finishing, sump pumps and crawl space work across Massachusetts and New Hampshire and says it has been in business 20 years, while its Houzz listing carries a self-reported claim of being fully licensed and insured. For a wet basement, a sump pump, or turning unused basement space into rooms around the Merrimack Valley and southern New Hampshire, this is a strong shortlist call — particularly if another company has quoted you for a full system and you want a second opinion. Ask for licence and insurance certificates before work starts, and get the scope and the schedule in writing.
They are professional and knowledgeable! Highly reccomend them for any basement systems!
We couldn't be happier with our experience with Northeast Basement Solutions! From start to finish, every aspect of the process exceeded our expectations. The crew was professional, courteous, and clearly took pride in their work. They installed a french drain system along with additional waterproofing measures, and the quality of the finished work speaks for itself as our basement has been completely transformed. What really stood out was how clean they left everything when the job was done. A major basement project is inherently messy, but you'd barely know they were there. The pricing was fair and transparent with no surprises, no upsells, just honest value for excellent work. And when we had follow-up questions after the job was complete, their customer service was just as attentive as it was on day one. We've already hired them again for additional work, which says everything. If you're on the fence about who to trust with your basement, look no further. Northeast Basement Solutions has earned a customer for life.
We’ve had a few different companies work on our home over the years, and Northeast Basement has been by far the best. Their entire team was responsive, helpful, and always willing to answer any questions we had during the remodel. Dan, in particular, was proactive in making sure everything went smoothly—he consistently checked in and kept us updated on the progress of the project. We couldn’t be happier with the results and would gladly recommend them to anyone considering a basement remodel.
Highly recommend Northeast Basement Solutions. Miguel, Amanda and their team are excellent. Great communication, service, and high quality work. They take pride in their work and it shows. We would defiantly work with them again.
Miguel and his team did a great job from start to finish. Unlike the other basement waterproofing companies that wanted to charge exorbitant amounts for unnecessary work Miguel knew from his 24 years of experience all I needed was a sump pump and charged a much more reasonable price for a great pump. I look forward to having them back to quote out finishing the rest of the basement in the future. Thank you for your honest work.
