Verified record
JMC Masonry and Home Improvements is a Boston-based masonry contractor doing chimney repair, foundation and basement waterproofing, retaining walls, drainage, and stone patio and mortar work, self-reporting 34 years of experience. The 25 reviews on file, all on Angi, are uniformly five-star and describe specific completed jobs — mortar and expansion-joint repair, foundation repair, a stone patio build, and chimney repointing — with reviewers praising punctuality, fair pricing, and craftsmanship, and several naming Brian directly for clear communication and thorough work. A couple of things are worth knowing about the record itself: all 25 written reviews on file share the identical posting date (May 2023), which is unusual for organic customer reviews and worth treating cautiously rather than as confirmed independent feedback spread over time. Separately, the company's own Angi and HomeAdvisor profiles advertise a lifetime warranty in their self-written blurb, while the same pages' own FAQ states the business does not offer warranties. For chimney, foundation, or masonry patio work in the Boston area, the specific project detail in the reviews is a positive sign, but it's worth getting warranty terms in writing given the direct contradiction on the company's own listing pages.

Brian did a good job for my project. He worked very hard to do my projects exactly as I wanted and did not give up until it was right! Highly recommend!
