Verified record
Keenan Masonry is a family-owned mason contractor based in North Attleborough, run by Sean Keenan (with Sue Keenan listed as owner on its BBB profile), and the Better Business Bureau credits the company with 36 years in business. Its Massachusetts home improvement contractor registration is active. What sets this record apart is the depth of specialized, historic-home craftsmanship reviewers describe. Customers with century-old and older houses repeatedly hired Keenan specifically for period-correct restoration: a 200-year-old chimney rebuilt to match the original, a 90-year-old fieldstone chimney re-pointed to look, in one reviewer's words, like it was built last week, and a 100-plus-year-old fieldstone foundation carefully repointed with attention to the house's age and construction. Beyond chimneys, the reviews describe patios, walkways, granite and bluestone steps, and full front-step rebuilds — one homeowner even had Sean build steps from a 3D drawing they'd created themselves. A recurring theme across years is daily site cleanup, clear communication about scheduling and cost before work began, and a willingness to adjust when a project turned up surprises, like rotted wood discovered under an old threshold during a 2025 steps replacement. The record isn't flawless. A review from 2026 — while praising Sean's team as professional and the completed walkway installation as nicely done — described being extremely dissatisfied about a separate issue the review doesn't fully spell out, a real account that stands apart from the otherwise strongly positive pattern. Keenan also does larger commercial work: a 2026 review describes a large multifamily project in Lincoln completed ahead of its estimated timeline while staying compliant with OSHA standards throughout. For chimney restoration, stonework, or masonry on an older Massachusetts home, this is a genuinely specialized track record — the kind built on customers who specifically sought out historic-appropriate craftsmanship and got it, with one recent account worth asking about directly.
I don’t normally leave negative reviews, and I want to start by saying that Sean and his team were great to work with. They were professional, friendly, and overall did a nice job with the installation and walkway itself. I've even recommended them to others. However, I am extremely disappointed with the long-term outcome of this project. Almost immediately after the installation in 2023, water began pooling behind the new stone background, causing noticeable staining. We reached out multiple times to have this addressed, but no solution was ever identified. We were ultimately told to clean it with vinegar and water — which, as you can see, has not resolved the issue even after three years. In addition, shortly after installation, the platform itself became stained from something as simple as water dripping off a flag and nearby bush after a rainstorm. We were never warned that the stone would be this sensitive or prone to staining. Had we known, we absolutely would not have chosen this material. This was a significant investment for us new homeowners — about $3,000 — and now we’re stuck looking at stained, unattractive stairs every day. It’s frustrating and disappointing that a project we were excited about turned out this way, with no real resolution despite multiple attempts to address the problem.
I have had the pleasure to work with these guys on a current project fairly large multifamily unit in Lincoln. They have been nothing but professional push through the project beat their estimated time of completion and most importantly were compliant with all OSHA standards while performing the services I would highly recommend them to anyone that needs any type of masonry work. The whole team is amazing and Sean the owner is a fear, understanding, easy to work with guy who Gets the industry and Attention to detail is off the charts. Thanks again to the whole team getting us there!!!
Wife and I had our front steps completely replaced which once demo work done, found wooded threshold wood rotten which added to the work. Sean, Casper, and Brian did an outstanding job which we are extremely happy with the results. They listened to our desired design, provided feedback with suggestions. It was a joy to have conversations with the 3 of them.
They did a great job rebuilding my chimney from the roofline up. The brick match is spot on and then Sean did a color tint match by hand. Came out great. Truly craftsman touch. Thanks Keenan masonry. I highly recommend
Professional and reliable. Great communication from the start. Friendly, polite, hardworking crew. Cleaned up everyday. We needed repointing of the fieldstone foundation in the basement of our 100+ year old house. Sean showed knowledge and experience in this type of work. He came by a few times during the week to check on the work being done. Our stone foundation looks SO MUCH better, and is now good for decades ahead. We were pleased with the whole experience and the results. We definitely recommend Keenan Masonry to others, and will keep them in mind for future projects. We will add that the work ( repointing of the stones and then parging over the entire walls) came at a fair price.
