Tony Walsh's crew takes on the kind of job you have to live through. In a March 2026 review a family said Mayo Construction redid essentially their whole interior — bathrooms, kitchen, HVAC, plumbing, all the finish work — and they came out of it happy. Another homeowner that same month had a significant renovation and expansion delivered on time, and made a point of saying the subcontractors were good to deal with too. Mayo is a family- and locally-owned general contractor working out of Walpole and, by its own description, the Greater Boston area. Its Massachusetts home improvement contractor registration, #126244, is active on the state registry in the company's own name. Additions are the backbone of the work: a 2015 Houzz reviewer's 1930s house was roughly doubled by an addition built to sit naturally against the original, and that customer hired the firm again later to gut and renovate two bedrooms. Another 2015 customer had been using Mayo since a 2001 addition that took in a kitchen, bathroom, family room and porch. Smaller exterior projects turn up as well. In a March 2026 review a homeowner had the front porch and back deck rebuilt, and walked through it from the first consultation to the final cleanup. A 2015 customer had a new front entrance, the house re-shingled and its original windows re-trimmed, brick and stone front steps, and a full repaint. Reviewers going back to 2015 keep mentioning the same two things: being kept informed while the job ran, and a work site left clean at the end of the day. Two items to sort out before you sign. How long they have been at this depends on which page you read — the Houzz profile field says 28 years, its own About text says 20, Angi says 26 — and the customer who dated a first job to 2001 puts it somewhere in that range. Houzz also lists a Westwood address and a phone number different from the Walpole one on the company's own website, so use the number on mayoconstructioncorp.com. Worth knowing too that the written history leans old: seven of the eleven accounts run from 2015 to 2018, five of them posted inside a single week in November 2015. For an addition, a whole-floor renovation, or a porch-and-deck rebuild around Walpole, this is an owner-run outfit with active state registration and customers who came back for a second and third project. Confirm the registration number, and get the schedule written into the contract.
I have worked with Mayo Construction on many projects over the years. They built a large addition to the house and subsequent smaller projects. These included updating and remodeling bathrooms, repair work on the outside of the house, etc We have been extremely happy with all of the work they have done and can highly recommend them to anyone who is looking to build or remodel. We continue to call them for any work that we need done in our house.
We had a great experience with Tony and Mayo construction. They completed a significant home renovation / expansion of our home. The quality of the work was excellent - all of the subs were great to work with. They completed the job on time - we are very happy with the results. Would definitely recommend Mayo Construction.
We had a great experience working with Mayo Construction on renovating our forever home! Couldn't be happier with the work Tony and his crew did, which was quite extensive. They pretty much redid the entire interior of our home (bathrooms, kitchen, HVAC, plumbing, finish work, etc.) and all of the workmen and subcontractors were professional and easy to work with. We felt comfortable throughout the entire process, as we were regularly kept in the loop on any major decisions/milestones. We are truly appreciative of the communication, the effort to stay within budget, and the willingness to work through the "challenges" that tend to come with renovating an older home. Tony was especially patient with our (endless) questions and he and his subcontractors were transparent and honest with their answers. Our project has been done for just over a year now, and we're so grateful! Would highly recommend Mayo Construction!
We recently hired Mayo to rebuild our front porch and back deck, and we couldn't be happier with the results. From the initial consultation to the final cleanup, the team was professional, communicative, and detail-oriented. The craftsmanship on both structures is outstanding, and they finished the project right on schedule. It has completely transformed our outdoor living space. Highly recommend them to anyone looking for quality carpentry and reliable service!
We have been settled in our remodeled home since early Summer and we could not be happier with how everything come out. We love the extra space, the layout and all the details throughout the house. We hosted a Xmas party this past weekend for a large group of friends and we received so many compliments! I've always wanted to throw big parties and the work that Tony and his crew did allowed me to do just that! I am so appreciative of the partnership Tony showed us throughout this whole project. It was a big project that took almost a full year and Tony remained on schedule, even as we added a bunch of items to the project. We lived in the house while under construction with 4 young kids and while it was not easy, Tony and his crew made it as bearable as it could have possibly been. Everyone was very skilled, respectful, friendly and communicative. I love everything about the house now and appreciate the honest feedback Tony gave us on what would work and what wouldn't and in particular how honest he was regarding areas where we were possibly overspending. That feedback always made us more comfortable because it showed that Tony had our best interest at heart.
