Foundation Crack Seal

Foundation Crack Seal is a Millis-based foundation repair and basement waterproofing contractor serving the MetroWest Boston area — crack injection, waterproofing, stone repointing, French drains. By its own account the owner, Garrett, works every job himself, and he's the person named in nearly every review on file. The written record runs from mid-2021 through this past June, and the same story repeats across it: Garrett shows up when he says he will, explains the problem and the fix before starting, and stands behind the work with a 10-year transferable warranty. In a 2025 review, gaps around a waste pipe running to a septic field were resealed so quietly the homeowner didn't realize the crew was in the basement. Another 2025 account described years of persistent leaks and dampness finally resolved, with a clear explanation and a fair, itemized estimate. In a 2023 review, a homeowner whose newly installed bulkhead leaked was left stranded when the installer that put it in stopped responding — Garrett fixed the seal, and it's stayed dry through heavy rain since. A 2022 review described repairing cracks and gaps in an old fieldstone foundation within three days of the first call. Angi lists the business as accredited with a 5.0 rating, though that's based on just two reviews there — most of the record sits on Google. For a foundation crack, leak, or waterproofing job in the MetroWest area, this is a small, owner-run operation with a long, consistent track record on exactly that kind of work.
