Thompson Waterproofing, Inc.

Eighteen building permits, and almost none of them are houses. Thompson Waterproofing works out of 93 Federal Ave in Quincy, and its permit trail runs through commercial masonry restoration — repointing, sealant and waterproofing work on buildings in Brookline, Chestnut Hill, Cambridge, Newton and Barnstable, at a typical permit value around $131,000. The Better Business Bureau puts the company at 35 years in business, started in May 1991, with five employees and Ms. Lisa Higgins as president. On Procore, where it keeps a claimed listing, the company describes itself as a general contractor doing waterproofing, air barriers, dampproofing and masonry for commercial, healthcare, infrastructure and institutional clients across Massachusetts and Rhode Island — 33 projects since it joined in April 2022, 11 of them still active. Five of its 18 permits came in the past three years, so the work is current. What there isn't is a customer trail. Nobody has written a review of the company on its BBB, BuildZoom or Procore pages, which leaves permits and licence filings to go on and nothing from anyone who actually hired them. Those licence filings are worth asking about. Its Massachusetts home improvement contractor registration, #185597, is expired — that comes from the state registry itself, which names Thompson Waterproofing Inc as the holder of record — and BuildZoom shows the same number as inactive alongside an inactive Massachusetts asbestos contractor licence, #AC000929. The zero BuildZoom attaches to the profile is not a verdict on the workmanship; the site says plainly it scores 0 because it cannot verify an active licence. The BBB, for its part, grades the company A+ without accrediting it, and publishes no complaints and no government actions. If you own or manage a building with failing masonry — repointing, sealant replacement, waterproofing a wall that's letting water through — this is a Quincy firm that has been doing that kind of job around Greater Boston at six-figure permit values. For a single house the fit is less obvious: the sectors it names for itself are commercial, healthcare, infrastructure and institutional. Either way, the first call should settle whether that expired state registration has been renewed, and whether the work you have in mind requires one.
