Verified record
AGM Construction is a Beverly, MA masonry and concrete outfit that shows up in reviews for stonework: crumbling foundations restored, brick walls repointed, natural stone walkways built by hand. Thumbtack lists the company as in business 21 years and having passed a background check, and the reviews on file all carry the name George, suggesting a hands-on owner-operator shop. Every review on file, running from 2023 through mid-2025, is five stars, and several go beyond generic praise. In a 2025 review, a homeowner described George restoring crumbling cement and loosened stones around a triple-decker's foundation in Boston, walking the building with the client before starting and leaving the work neat and clean. A 2024 review described AGM repointing and sealing a large interior brick wall in a condo, showing up on time every day and doing extra work at no charge. Another, from 2023, described George and his family building a natural stone walkway, calling the pricing fair. A separate 2024 Thumbtack review described a full porch repair completed on schedule with options explained clearly. There's nothing in the record from the past year, so it's worth confirming current availability directly. AGM looks like the right call for stone and masonry restoration — foundations, brick, walkways — rather than broad remodeling; confirm scope and scheduling for your specific job before booking.

"Excellent masonry work! With great attention to detail. Everything was done on time, and the results speak for themselves—solid, clean, and beautiful. Highly recommended!"
I hired George to restore the crumbling cement and loosened stones around the corners and sides of the foundation of my triple decker in Boston. He struck me as highly intelligent, very thorough, and with a slight perfectionist streak. We did two circumambulations of the building, and reviewed the interior. He wanted to make exactly sure he understood what I wanted from him and how he thought he could best do it. I appreciated his thoroughness, both before he began the job and in his execution. His work was neat and clean and accomplished exactly what I needed. I will definitely be hiring him for my future masonry work.
AGM repaired a large brick wall inside our condo repointing and sealing the bricks. They were on time everyday, communicated what they were going to do and what to expect and they were extremely courteous and pleasant to work with. They also did some extra work related to the project without charging us. I am so glad we went with them. Best contractor experience I have ever had.
AGM Construction exceeded all my expectations! From start to finish, their team was professional, communicative, and incredibly skilled. The quality of their work is outstanding, with attention to every detail. They delivered on time and within budget, making the entire process smooth and stress-free. I couldn’t be happier with the results and highly recommend AGM Construction to anyone looking for top-notch construction services.
My job which was a complete porch repair went very well…was done in reasonable time with all options explained well. I would gladly hire this crew again
