Verified record
Queen Foundation Repair (QFR), a Boston-based DBA of Conversion Lab LLC, works foundation and crawl-space problems — helical piers, French drains, sump pumps, egress windows, basement waterproofing, and crawl space encapsulation — and its strongest evidence comes from a run of detailed 2024 reviews describing named project leads staying involved well past the invoice. In one, Felipe recommended and supervised pier-and-beam repairs on a 1936 home in 2019, and QFR came back four and a half years later for a routine check that confirmed no further work was needed. In another, John's team installed piers to stop a house from sinking, waterproofed and encapsulated the crawl space, and put in a leveling steel beam three years earlier; the homeowner still calls John with questions and says he's come back multiple times to verify things were still working (one call turned out to be an unrelated plumbing issue, not his work — and the review credits him for saying so). A third describes John assessing a garage floor and telling the homeowner the unevenness was a "minor nuisance," not something requiring immediate repair. A large share of the more recent reviews, though, is harder to read as ordinary customer voice. Starting around late 2025, dozens of five-star reviews describe similar jobs (crack repair, sump pumps, crawl space sealing) in a recycled, inconsistent register — casual misspellings like "n" and "goin" sit next to abrupt bursts of ALL-CAPS emphasis ("WONDERFUL," "SUPERB," "STRAIGHT"), and most refer to the crew only as "these guys" or "this team" rather than a name. That doesn't mean the underlying work described is fictional, but the pattern is different enough from the earlier, specific 2024 reviews that it's worth reading this recent run with some skepticism rather than at face value. Google shows a 4.9★ average from 45 ratings, all logged since 2024, with no negative review in the record. For a real foundation, pier-and-beam, or crawl-space problem, the older, more detailed reviews here point to a company that stands behind its diagnosis and its work years later — but get a second opinion on price and scope, since the newer review volume shouldn't be weighted as heavily as it looks.

We were concerned that a small leak would turn into major damage. Queen Foundation Repair inspected everything thoroughly, and Javier made the entire basement waterproofing process easy to understand.
This team did a great job installing a sump pump and improving drainage around our home. No more standing water issues at all.
We had water coming in during storms, and these guys installed a full interior waterproofing system. It’s been completely dry ever since.
Our home feels much safer now after these folks sealed the cracks and improved basement waterproofing.
Honestly impressed with how Juan Carlos made sure the whole basement waterproofing job was done properly.
