Verified record
Sigma Masonry And Construction is a Cambridge, Massachusetts outfit doing concrete and masonry work — foundations, retaining walls, chimney repairs, tuck pointing — alongside patios, waterproofing, and roofing and siding, according to its own directory listings. The two reviews on file, both posted in June 2023, are positive but brief. One customer wrote that "the service was good and they did a great job" and that the crew "were clean and organized," giving five stars. A second reviewer gave four stars and said simply the job "went very well." Before booking, know that this reflects a small, three-year-old written record rather than an ongoing or detailed one — neither review names the specific job performed, and there's nothing more recent on file to go on. For concrete, foundation, or chimney work in the Cambridge area, the two reviews on hand are favorable, though thin enough that it's worth asking directly about a recent, comparable job before committing.
