A-1 Foundation Crack Repair, Inc.

A-1 Foundation Crack Repair is a Hudson-based foundation and basement-waterproofing specialist with one of the largest, most consistently positive review histories in this corpus — 4.9 stars across 503 Google reviews and 4.8 across 47 on Thumbtack, a BBB A+ accreditation, and 290 total reviews dating back to 2021. The through-line, repeated across dozens of reviews, is a company that says no as readily as it says yes. In a 2026 review, one customer said you know a contractor is great when they take the time to look at a project and then tell you that you actually don't need their help; other reviews from early 2026 describe technicians who never felt like they were trying to sell more work than necessary. In a 2025 review, a homeowner credited Adam with reviewing photos and confirming that a leak was not, in fact, the $28,000 foundation problem another company had quoted. Rich and Adam, the names that recur most, are also described answering calls on weekends — a Saturday-afternoon quote within minutes, a Sunday-morning response — and a 2025 review described the company answering over a weekend and diagnosing a bulkhead leak immediately after other waterproofing companies had only pushed expensive drainage systems. Repairs are also described holding up: a 2024 review said a 12-year-old competitor's patch was "totally transformed" and stayed dry through repeated storms, and a mid-2025 review described a bone-dry basement nine to twelve months after seven cracks were sealed under a 10-year warranty. The record isn't spotless. A run of reviews from mid-2024 through mid-2025 — several one-star — described leaks that returned after treatment, a crack sealed only partially on the first visit, and one job that took four service calls without resolving the leak. A 2025 review also described the business changing hands from the original owner to a son-in-law, with that customer reporting reduced helpfulness afterward. None of that shows up in the last six months, during which every review on file has been positive. Separately, the state registry shows A-1's Massachusetts home improvement contractor registration as expired. For crack repair, foundation waterproofing, or a second opinion before a home purchase, A-1's record and its habit of turning down unnecessary work make it a strong first call — worth confirming current licensing directly, and, for a larger job, asking about the outcome of a similar past repair.
