Inner Boston Masonry & Construction works out of Dorchester, and the calls that keep coming in are the structural kind — a foundation settling under an old porch, a chimney pulling away at the roofline, a retaining wall on the verge of failing. The company holds an active Massachusetts Home Improvement Contractor license (HIC #209229) and says it serves the greater Boston area. The owner, Mark Dunn, shows up in review after review by name — not just as a signature but as the person actually running the job. In June, one homeowner had him repoint cracked exterior walls and add a waterproofing and parging layer under a porch foundation; another hired him after being burned by competitors' band-aid chimney fixes and called him "knowledgeable and trustworthy." A third had an 8-foot-high, 110-foot-long retaining wall and its mounted fence rebuilt and said the job "exceeded our expectations." Smaller jobs get the same treatment — a moss-covered roof cleared in January, a stucco and EIFS job the same month, foundation and stair repairs in April with the process explained step by step before work started. That pattern holds across 30 Google reviews going back to mid-2025, all five stars, with the most recent six months alone producing 12 reviews and not one negative. A separate Angi listing shows a 5.0 rating from 41 reviews with an "Approved Pro" and "Super Service Award" badge — though that rating currently surfaces inside a related-pros sidebar on a different masonry company's Angi page rather than on a page of its own, so it's worth confirming directly with Angi or the company before leaning on it. None of the thirty reviews gets into pricing specifics, warranty terms, or how the company handles a job that goes sideways — the closest thing to friction is that Angi mix-up. For foundation, chimney, and retaining-wall work in the Boston area, reviewers describe a hands-on owner who explains the plan, shows up as scheduled, and cleans up after himself; confirm the license and get a written estimate before signing anything, and double-check that any Angi reviews you find actually belong to this company.

5/5 Stars – Highly Professional and Reliable!<br><br>I had an excellent experience working with this masonry team. They recently repaired several cracked sections on our exterior walls by repointing them, and they applied a thick, protective parging/waterproofing layer to the foundation walls under our front and back porches to mitigate future risk from humidity and lack of sun.<br>From start to finish, the crew was incredibly professional, efficient, and respectful of the property. They stuck exactly to the committed schedule and completed the work on time without cutting any corners. Best of all, there were absolutely no surprises or hidden costs—just honest, high-quality craftsmanship.<br>The finished job looks fantastic, and I have total peace of mind knowing the structure is well-protected. If you are looking for a skilled, reliable mason who delivers exactly what they promise, I highly recommend them. Job well done!

When I needed to find a contractor to fix my chimney which was pulling away from my house at the top, I contacted numerous contractors for their assessment and cost estimate. Some never responded, others recommended what sounded to me like ineffective band-aid solutions, and a couple gave me reasonable advice and estimates. I chose Inner Boston Masonry because Mark seemed so knowledgeable and trustworthy. I’m very glad I did. He and his team got to work right away, came on time every day until the work was completed, kept me well informed every step of the way and did an excellent job. I would highly recommend this company and they will be my “chimney people” forever.

I can't say enough good things about Mark Dunn and the team at Inner Boston Masonry & Construction. We hired them to repair 8-foot-high, 110-foot-long retaining wall, along with the 5-foot-high metal fence mounted on top of it and the entire experience exceeded our expectations.<br><br>The owner, Mark Dunn, provided a competitive quote, clearly explained the repair plan, and communicated with us throughout the project. He visited the site daily, shared progress photos, and quickly addressed any unexpected issues with practical solutions. The workmanship was outstanding. The retaining wall is now structurally sound and looks fantastic, and the fence was carefully repaired, cleaned, and painted. Mark and his crew were professional, hardworking, respectful, and kept the work area clean every day.<br><br>It's rare to find a contractor who combines quality craftsmanship, reliability, honesty, and excellent customer service. We are extremely happy with the results and would hire Inner Boston Masonry & Construction again without hesitation. Highly recommended.

I highly recommend Inner Boston Masonry & Construction. Mark and his team did an excellent job repairing our retaining wall, side walkway, and resurfacing the concrete underneath our deck.<br><br>Mark was responsive, professional, and took the time to explain the projects and answer our questions. He was also very kind and easy to work with throughout the process. I would gladly work with him and his team again and highly recommend them to anyone looking for masonry work!
