Verified record
State Line Masonry is a Waltham-area masonry and waterproofing company. Its public profiles describe masonry work and list a Massachusetts home-improvement license number, while customer reviews from 2024 praise punctual completion, an easy experience, and affordable craftsmanship. The review history is small: three Angi/HomeAdvisor reviews, rated 4.7, with customers mentioning that scheduled work finished as promised and that they would hire the company again. BuildZoom lists 14 photos and a score of 97, but that score is not a customer rating. Before booking, confirm the license status and the exact scope in writing. Angi and HomeAdvisor present license 213297 as self-reported with a September 15, 2026 expiration, while BuildZoom lists it as active; the business-history figures also differ between BBB and the other profiles. This is a reasonable candidate for masonry or waterproofing work when the proposed scope matches its documented services. Ask for a current license check, a written estimate, and recent comparable project references.
Typical Greater Boston range for this kind of work, from regional averages — not a quote from State Line Masonry. Use it to sanity-check bids, then get the real number in writing.
Not sure which you need? Start with an inspection — many reputable companies assess free, and independent assessments run up to $500.
The wall run getting the drain — a full 30×40 ft basement is about 140 ft.
