A Rhode Island homeowner writing in December 2024 said Capital Building & Design put two dormers on his second floor, turning one long room into two bedrooms, and that the work was done about seven years earlier. That is the kind of job this Swansea firm takes: design-build work on existing houses, with design, architecture and project management staff in house, across southeastern Massachusetts and Rhode Island. It is a family business — Ron Eaton is president, with Cheryl, David and Doreen Eaton on the team page. The Better Business Bureau records it starting in 1999, incorporating in Massachusetts in 2001, with 30 employees, and grades it A+ on an unaccredited profile. Its Massachusetts home improvement contractor registration, #128626, is active on the state registry. Customers who liked the work describe the whole process rather than just the carpentry. An April 2025 reviewer walked through initial consultations, budgeting, design and municipal approvals; another that month had a total rehab of a Swansea house and credited the company with getting through a difficult permitting process. A third said they do what they say without cutting corners, and that you may find cheaper bids. The Houzz reviews tell the same story a decade earlier: a full renovation of an 1865 Cambridge house with custom cabinetry and an AC system worked in by project lead Paul L. in December 2015, kitchen, mudroom and master-suite additions for a repeat client in June 2014, and a flood-damaged basement rebuilt to resist the next flood in January 2014. Two one-star Google reviews pull the average to 4.2 across 15 ratings. In January 2022 a homeowner wrote that Ron came out to assess the project and said an estimate would follow in about two weeks, and that nothing came. The other, from December 2024, is about a company vehicle tailgating on the way to Newport at 6 a.m. rather than about any work done. There is also a safety matter to know about: a workplace-safety page reports a formal OSHA inspection of a Capital Building & Design, Inc. residential-remodeling site at 28 Oak Grove Avenue in Barrington, Rhode Island, which resulted in three citations and proposed penalties of $3,456.60. For a design-heavy addition, a whole-house rehab, or a project that has to clear a tough permitting board, this is a strong call on the Massachusetts–Rhode Island line. Pin the estimate timeline down in writing at the first visit, which is where one customer's experience came apart, and ask who your project manager will be.
“I had good experience with CBD... That's capital building and design out of Swansea. (http://capitalbuildinganddesign.com/) They added two dormers on the second floor to make one long room into two bedrooms. They did the work for my house about 7 years ago.”
“CAPITAL BUILDING & DESIGN, INC. — a residential remodelers facility located at 28 OAK GROVE AVENUE, BARRINGTON, RI 02806 — was the subject of a formal OSHA inspection that resulted in 3 citation(s) and cumulative proposed penalties of $3,456.60.”
I routinely recommend Capital Building and Design to friends and family. Our entire experience with the family-owned company was amazing, from initial consultations and budgeting to design and municipal approvals, and (of course) the quality of work was amazing across the board. The open communication with the entire team throughout the process of building our home addition ensured it was completed on time and on budget! Every carpenter, excavator, electrician, plumber, flooring expert...every single member of the CBD team that worked on our project treated us like this was their own home project, and that's something you can't replace. 10/10 recommend CBD for your home construction and renovation projects!
We had the great fortune to have found Capital Building and Design for a total rehab of our house in Swansea. From design to finish they were and are a terrific family run business. They navigated through a very difficult permitting process seamlessly and delivered on every single piece of the refurb. We went from the ugliest house to the most beautiful in (6) months. In our initials discussions I was told " we can make this your dream home" it is and they did. The management is top notch, communicating and making field changes and suggestions to bring the project in on time. The craftsmen working in the field are very talented and a solid team of all manner of trades. Excellent work. The job site was clean. There were no change orders that were not discussed and figured out ahead of time. The most honest and genuine people I've had the pleasure of working with in 35 years.
If you want great carpentry and construction work, and you’re looking for a company who does what they say without cutting corners, you won’t be disappointed. Honest people who are going to do the right thing. If you’re looking for quality look no further. You may find cheaper but remember… “The bitterness of poor quality remains long after the sweetness of low prices is forgotten “ Capital is the right choice.
Speedy and tailgating all the way to Newport at 6AM . Very professional. Enjoy your review bud!
After having the owner, Ron, come out to assess our project needs, where at the end, he said, we could expect an estimate in about 2 weeks-- we never heard back. Giving them some breathing room knowing that service professionals of all types are very busy since covid-19 struck in early 2020, we waited approximately 2 months to reach out to find out what and where the estimate is. Giving that they were recommended by friends of ours we did not seek out another estimate (mistake on our part). My wife and I attempted to call about 7 times in the course of another couple of months which put us 4 months behind and got no response back. If this is the way they treat potential customers I can't imagine what it would be like trying to get them to be responsive to concerns or finishing jobs once there started; most of us probably heard of horror shows of jobs started and taking months to finish because the company ultimately attempts to dangle several jobs at the same time. I believe that maybe we were spared that outcome--that "if its meant to be..." It apparently wasn't. Beware!!!
