Foundation expert waterproofing and masonry

Foundation Expert Waterproofing and Masonry is a family-run Cambridge outfit that handles the un-glamorous foundation work — basement waterproofing, sump pumps, masonry repair — plus roofing and siding on the side. The company says it's family-operated, with the owners working the jobs themselves rather than just supervising, and it advertises decades of experience in the trade. Its Massachusetts home improvement contractor registration is active, verified against the state registry. On Angi, all three reviews on file are five stars: in a 2025 review, one homeowner described hiring the company for a mix of projects at a newly purchased property — chimney repainting, a sump pump, basement waterproofing, and a full roof-and-siding job — calling the work high-standard, fair-priced, and the staff professional. Two other 2025 Angi reviews single out the roofing and waterproofing work specifically, both calling the experience efficient and professional. There isn't much else to go on: the company isn't BBB accredited and has no BBB customer reviews, so the Angi feedback is essentially the whole written record. That's not a red flag by itself, but it's worth asking around or requesting references before signing a bigger job, since there's little history to lean on beyond those three accounts. Worth calling for basement and foundation work or masonry, and apparently capable of larger multi-trade projects — just confirm scope and pricing in writing given how small the review sample is.
