Associated Concrete Coatings has been doing concrete work in Manchester since 1969 — more than 50 years the company points to on its own site — and today it's a specialty coatings and waterproofing contractor working mostly for businesses and institutions across New Hampshire, Massachusetts, Vermont, and Maine, though it also takes on more complex single-unit residential jobs. The reviews on file are recent and specific about what people hire the company for. In a February 2026 review, a multi-location client described epoxy flooring installed at five of its sites, calling the crew accommodating on scheduling, consistently on time, and praising the quality of the finished floors. A January 2026 review, focused on foundation waterproofing, put it simply: the reviewer said they wouldn't call anyone else for that work. Institutional and commercial clients back that up at scale — the company tracks 246 projects on Procore Construction Network since 2022 across healthcare, industrial, infrastructure, and other commercial sectors, and it carries a Better Business Bureau A+ accredited rating along with membership in the Associated Builders and Contractors and the International Concrete Repair Institute. This is a strong call for commercial-scale epoxy flooring, concrete repair, or foundation and basement waterproofing, especially for a multi-site business or a larger institutional project; for a smaller single-unit residential job, confirm upfront that the company is taking on work of that size before reaching out.
