ESI Waterproofing and Masonry Restoration, Inc.

ESI Waterproofing and Masonry Restoration works at a different scale than most residential contractors — the reviews here describe $30,000 to $500,000 projects, repointing entire buildings and correcting problems on structures over a century old. The Boston-based company says it's been doing this since 1987, and its DCAMM certification (needed for Massachusetts public-agency work) plus a long list of manufacturer-approved-contractor credentials — Sika, 3M, Vulkem, Dur-A-Flex among them — point to a firm built for institutional and commercial masonry and waterproofing work, not just homeowner jobs. The written reviews back that up: a 2023 review describes engaging ESI for a string of projects over three years, all delivered on time and on budget regardless of size; another from the same year credits the project manager's communication on a two-building repointing job; a third describes ESI correcting unforeseen problems tied to a building's age the right way rather than papering over them. Even a fellow contractor — Advanced Scaffold Services of New England, writing in 2023 — says the crew is professional and easy to coordinate with on site. Google shows a perfect 5★ from 11 ratings and BBB carries it at an A+ (though the business isn't BBB-accredited). There isn't a public complaint or dispute on record here, and the review volume is modest for a company this established — likely a reflection of a commercial/institutional client base that doesn't leave Google reviews as often as homeowners do. For a larger masonry, waterproofing, or restoration project — especially one involving an older or public building — ESI's credentials and multi-decade track record make it worth a call; it's less suited to a small, one-off residential repair.
