Nantucket custom builders M. Sweeney Construction, Inc. believes the process of building or renovating a Nantucket home should be an enjoyable experience. All the components should come together in careful harmony to successfully bring a client’s vision to life. This is where our work as Nantucket custom home builders truly shines.

With meticulous attention to detail and experience in all layers of contemporary home building and historic renovation and preservation, M. Sweeney Construction Inc. takes pride in understanding every project from a 360-degree perspective. We have great relationships with Nantucket architects and have been working with exceptional tradespeople on Nantucket for over 20 years.

We are passionate about our work and embrace a challenge. That mindset of challenging convention and looking at things differently also means that we’re often reviewing things we’ve done and re-assessing whether they still meet our high standards for quality and efficiency. We make time to have fresh ideas and make room to put them into action.

We believe the key components of a modern construction company are organization, craftsmanship, attention to detail, transparency in billing, and good communication.

M. Sweeney Construction Inc. does not just build homes, we try to envisage our client’s experience from the moment they arrive on the island to their daily routine in enjoying their property to its maximum potential. This helps us form life-long partnerships with clients and delivers custom quality and on-island reliability.
