Hydroseal Basement Waterproofing

Hydroseal Basement Waterproofing is a family-owned outfit based in Fairhaven built around the basement problem you can't put off — a crack letting in water, a drain that isn't draining, a sump pump that needs to actually work. The company says it's family-owned and -operated, with the owner personally overseeing every job, and it works the South Coast, covering Fairhaven, New Bedford and Fall River into nearby Rhode Island towns like Newport and Bristol. Its own site states "Year Established 2021," though separate marketing copy on the same site also claims "over two decades of experience" — the two don't reconcile, so take the more specific figure as the more reliable one. The written record is unusually steady: 41 Google reviews since 2023, every one five stars, and the specifics repeat year over year rather than reading like a lucky stretch. Reviewers describe the owner (called John, Jon, or Jonathan across reviews) coming out the same day for an estimate, quoting a price and sticking to it even as scope shifted, and leaving a clean site after multi-day work — one job ran a jackhammer for three straight days to open a basement floor and still finished with a thorough cleanup. Several customers came back more than once: one hired the company twice for separate issues within seven months, and a 2024 review describes french-drain and crack work done eight years earlier as "still working to perfection". There isn't much to flag. The company is too new to carry a Better Business Bureau rating — its BBB file opened in March 2026 with no complaints or reviews on record — which is an absence of red flags rather than independent confirmation. The reviews are almost entirely about french drains, sump pumps, and crack or wall repair, so it's worth confirming upfront whether a given job is a component fix like these or a larger foundation project. Worth a call for a basement that's actively taking on water: sump pump installs, french drains, and crack repair are what this shop is built around, and it's consistently the owner showing up to do the work rather than a rotating crew.
