Northeast Basement Solutions

Across three dozen Google reviews stretching back to 2020, the same names keep showing up — Miguel, Dan, Amanda — and the same word: recommend. Northeast Basement Solutions is a Haverhill-based waterproofing and basement-finishing contractor that says it's been at it for 20 years, working across Massachusetts and into New Hampshire. The waterproofing side of the business gets specific praise. In a 2025 review, a homeowner described Miguel steering them away from an unnecessary upsell other companies had pitched and installing just the sump pump the job actually needed. Another described a sump-pump-and-backup system paired with a separate foundation-crack repair, photos attached. A 2025 review credits the team with a french drain and additional waterproofing that "completely transformed" a basement, and a 2023 review recounts them responding within days of a Christmas Eve flood to assess, quote, and fix the problem. The finishing side runs just as deep. A 2024 review describes turning a "dark and moldy" basement into a home gym — pulling out old drywall, doors, and ceiling tiles, correcting improperly wired electrical, and adding insulation along the way. A 2023 review details a 160-year-old house where the crew dug the floor down for ceiling height, poured a new concrete slab, and waterproofed the perimeter before finishing the space. A 2024 review describes a two-month buildout that added a bedroom, full bathroom, pantry, and entertainment space. Older Thumbtack reviews from 2020 and 2021 tell a consistent story on the carpentry side too — Dan framing, drywalling, and taping basements, with one customer saying he "saved me from a previous horrible experience." Google shows 32 ratings averaging 5 stars, and the Better Business Bureau gives the company an A- grade (it isn't BBB-accredited). Thumbtack lists the owner, Daniel Maillet, as background-checked with a self-reported OSHA 30 certification; its Houzz profile, by contrast, is currently suspended with no reviews posted there. Nothing in the record — six years of it, across three platforms — describes a job gone wrong. A solid call for basement waterproofing or a full basement finish-out, especially on an older or awkward foundation; with a team this consistently named in the reviews, it's worth asking directly for Miguel or Dan by name when you book.
