Michael "Sean" Connolly is licensed as a South Carolina Residential Builder and General Contractor. Familiar and in Good Standing with the Historic Preservation Society and Board of Architectural Review. CRAFTSMANSHIP MOTTO: Timelines and deadlines are very important to us, however we will not sacrifice quality to meet them.

If we do exceed a timeline, short term disappointments will be rewarded with long term satisfaction on a job well done. Hi, my name is Sean Connolly, owner of MSC Construction, LLC. I am a native Charlestonian and reside in the Hanahan area with my family. My wife, of 20 plus years, and I have four daughters and we became grandparents to a count of five grandchildren in 2019.
Services
From your crawlspace to your roof we provide advanced building systems to meet your needs. We use in-house service experts and licensed tradesmen for quality craftsmanship. Ask about our Portfolio and Portfolio Select lines of NAHB Green approved cabinets for design and installation.

An elegant bathroom, designed by Lauren Messina, completed for our Daniel Island clients, and featured in the Winter 2019 edition of Charleston Home + Design Magazine.Don and I want to thank you for all the help you and. the team did to remodel our 55 1/2 Legare Street house. We were both extremely impressed with your honesty and willingness to work to get our job done in an efficient manner.
MSC Construction of Charleston, SC, is experienced in all aspects of home remodeling and repairs, including kitchen and bath up-fits, crawlspace repairs, roof repair and replacement, CL-100 clearances, termite and pest damage repairs, and historic restoration. Small or large, your projects will be handled with the same level of expertise, professionalism and craftsmanship.
Sean listens, offers professional options, provides detailed proposals, supervises the project personally and constantly, and cleans up like it never even happened. He does not rest until the homeowner is totally satisfied. After putting aside the fears, dispelling the nightmarish stories of remodels gone bad, my wife and I decided to plunge into the deceptive world of contractors and builders.
We are experiencing a high volume of projects with a diminished (willing to work) labor force. This has resulted in longer than normal waits: Approx. 2 weeks to schedule an on site evaluation for estimation, a week plus to receive your estimate from date of site evaluation, and 5+ months before an approved project can be begin.
Although we do not provide in-house financing options, we would like to provide you with information regarding options and potential opportunities for financing your home improvements. For many hard working Americans, our home is one of the largest investments we make. Maintaining that investiment is crucial.

Sean and team remodeled our master bathroom, our first floor, including a kitchen remodel, and extended our deck. Sean’s team does great work and were always professional and courteous. Sean walked us through each process and kept us update to date on any issues before they became problems. We will definitely consider Sean for all our construction and remodel needs.

Sean Connolly and his team transformed my home into a modern open concept space that has become my dream kitchen. Mine was a big project of knocking down walls, adding support beams and columns, refinishing hardwood floors, all new plumbing, electrics, cabinetry, windows and doors. Sean and his subs were top notch and kept me posted on time tables and budget issues throughout the project. I could NOT be happier with the end result and having chosen the professional team that Sean put together. My space is beautiful and the value of my home has improved substantially.
