Waterguard waterproofing and foundation

Waterguard is a small, family-run masonry and waterproofing outfit based in Charlestown, Boston, doing foundation, chimney, and waterproofing work. It says its owners — with 60-plus years of combined experience — work directly on jobs rather than just supervising. The only two reviews on file, both from late 2024, describe positive experiences. One homeowner said a crew showed up on time, repointed and rebuilt the top two rows of a chimney, added a new cap, and waterproofed the whole structure, finishing in a single day and leaving the property spotless. Another described a chimney waterproof seal repair and front-step repointing, and said they'd recommend the company to friends and family. There's a serious flag to weigh against that: the state registry shows Waterguard's Massachusetts home improvement contractor registration as revoked, not merely expired or lapsed. Its BBB profile also carries a C- grade, citing an unanswered complaint, and it is not a BBB accredited business. Confirm directly what happened with the registration and whether it has since been resolved before hiring. With only two written reviews and an unresolved licensing issue, there isn't enough here to recommend confidently — get a clear answer on the registration status, and consider a second quote, before signing anything.
