Queen Foundation Repair

Queen Foundation Repair, operating as a DBA of Conversion Lab LLC, is a Boston-area foundation repair, basement waterproofing, and crawl space services company that also installs sump pumps, French drains, helical piers, and egress windows. The review record is deep and consistently positive across 2024 through 2026. Recent 2026 reviews describe basement waterproofing that stopped active leaks during storms, sump pump and drainage installations that eliminated standing water, and foundation crack repair before slab damage worsened. The multi-year history includes pier and beam repair on older homes (a 1936 house and a 1957 house), crawl space encapsulation that resolved humidity issues, bowing basement wall reinforcement for a rental property, and a leaning chimney straightened back into position. Several reviewers describe returning to the company for a second property or being referred by a neighbor after a prior good experience. Worth asking about before booking: one 2025 review noted a small miscommunication on scheduling that was corrected quickly, otherwise reviewers consistently describe clean, on-time work. For homeowners dealing with a foundation, basement water, or crawl space issue, the depth and consistency of this review record — with 12 reviews in the last six months and none negative — is a strong signal.
