Ronan redid our home when we purchased it. He has an incredible eye for detail and an artistic lens. Once we got to know him, we were more than comfortable trusting him with most every decision and by the end of the project, completely deferred to him to design for the den, dining room, and fireplace. He’s committed and passionate about his work. Can’t recommend him enough.

On time work, great quality, got the job done ahead of schedule. I was traveling on and off island, and I was thinking of doing some of this work myself and having Ronan's group handle the rest. It included repairs such as a replacement window, and a total cottage renovation. At least twice I told them "if you can get this done this week, fine, otherwise I can handle it this weekend". Each time, I'd show up, and the job was not only done but they had moved on to the next phase. The quality of work was solid, and the overall job got done ahead of schedule and on budget which was reasonable. This was a small/medium size job that many contractors on island won't look at. Some of the quality of work was way beyond what I expected...for instance installing shiplap in an old structure and taking the time to adjust the shiplap thickness to result in a glass-smooth surface. On a small job you often won't get 'Island Quality' work but I sure did.

Ronan has been terrific at all the jobs that he’s done at our home. From putting in multiple windows to getting very creative in our kitchen corner cabinets with a very efficient space “lazy susan” style cabinet. He repaired some floors for us as well as built us a bar! We value his experience and expertise as well as his craftsmanship! Would highly recommend!

I recently hired Ronan Bradley to install and refinish the hardwood floors in my home on Nantucket, and the results were outstanding. Ronan’s craftsmanship, attention to detail, and professionalism were evident from start to finish. He approached every part of the project with care, precision, and a level of expertise that is hard to find. The floors look absolutely beautiful—smooth, even, and perfectly finished. Ronan was reliable, respectful of my home, and communicated clearly throughout the entire process. It’s rare to find someone who takes such pride in their work, and it truly shows in the final product. I highly recommend Ronan to anyone looking for high-quality hardwood flooring work. He exceeded my expectations, and I would not hesitate to refer him to friends, family, or anyone seeking a skilled and trustworthy contractor.

Ronan’s work quality and attention to detail is second to none. He and his team helped us realize our vision for a carriage house / guest cottage, from clearing the land and excavating, to the final finish work. We couldn’t be more pleased with the final product!

Ronan was quick to come repair damage from a squirrel in the attic. Replaced destroyed drywall and vents. Assisted electrician with rewiring. Fantastic job from a friendly and fair priced professional.

We hired Ronan for a renovation of our home, and the results are even better than I could have imagined. Ronan was professional, organized, on time and on budget! He responded to every text or call almost immediately. No wondering for days or weeks on end if the job was going to get done or how much it was going to cost. After several previous home renovations with other builders whose budgets and times were way past any promises made, working with Ronan in contrast made the whole experience enjoyable. He kept the project site as tidy as possible at all times and communicated with me at every step. The few minor unexpected issues that arose were handled swiftly and professionally. The finished product is of the highest quality, and I wouldn't hesitate to work with them again. I can’t recommend him highly enough.

Frequently asked Questions

We are here to answer any and all questions you might have. Call us today to get started on your Nantucket building project or renovation.

How can I get started planning my Nantucket build?

Call Ronan Bradley at 774-236-1374 or request a call back. The first conversation covers what you want to build, where the property sits, and how far along your plans are. From there we put a dependable plan and timeline in front of you before anything is committed. Exterior work also goes through Historic District Commission review, and we coordinate that.

What kind of Nantucket homes does R. Bradley Build?

We focus on 2 to 3 bedroom Nantucket homes, pool houses, guest houses and garage apartments, generally under 2500 square feet. Staying in that range keeps one dedicated crew on your project from frame through finish. We also take on full renovations and restoration work on historic island homes.

Does R. Bradley Builders offer custom and restoration carpentry?

Yes, and it is the core of the business. Restoring historic Nantucket homes is Ronan Bradley's specialty. He trained through a four-year apprenticeship in Dublin, is certified by London City and Guilds, and brings more than 30 years in the trade. Framing, trim, finish carpentry, cabinetry and built-ins are all done by our own carpenters.

How do I schedule a bathroom renovation for my year-round home?

Call 774-236-1374 to get on the schedule. Bathroom renovation is one of our most requested services and our crew is on Nantucket year round, so we look after both year-round and seasonal homes. Because many island homes are occupied all summer, bathroom work often runs from autumn through spring.

What type of property management do we need for our Nantucket home?

If your house sits empty for part of the year it needs regular eyes on it. Salt air, winter storms and freezing temperatures cause most off-season damage. Our year-round caretaking covers weekly checks, heating and plumbing, electric, HVAC, painting and patchwork, power washing, window cleaning and in-house carpentry repairs, with specialists brought in through our trade network.
