Basement water problems are the job BBW Basement Waterproofing is built around. The Boston company says it has more than 20 years in business and serves Boston, handling waterproofing, foundation and crack repair, crawl-space work, French drains, and sump-pump installation. Recent Boston homeowners describe practical fixes: a March 2026 customer said BBW patched a cracking basement wall and waterproofed the area, while an April 2026 reviewer said the company stuck to its quote without adding charges or pushing unneeded work. Earlier customers described persistent leaks, damp crawl spaces, French drains, sump pumps, and foundation cracks being addressed. The written history is 18 reviews from 2024 through 2026, and the newest accounts are positive. BuildZoom lists seismic retrofit among its services, but its listing says the license status could not be verified, so confirm the registration and the exact scope of any proposed structural work before booking. BBW is a sensible call for basement moisture, drainage, crawl-space, or foundation-repair work in Boston. Ask for the written scope, warranty terms, and license details before signing.
