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.
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.

Sean has always his best to help our community. He does excellent work and his pricing is fair. His crew is Courteous and clean up after themselves. He has worked in our community for a few years and we have no complaints. I’m so glad he is one of our contractors.

Sean and team did an amazing job with our home. We renovated our first floor, added a room that acts as a sunroom, and finished the attic into a bedroom with a bathroom. The attention to detail was unparalleled.
Every space exceeded my expectations. MSC was always prompt, communicative, and cleaned up every evening before they left. I would highly recommend them.

We have a lovely home, but were desiring to change the Front door, from a single entrance door to a double door. We contacted Sean, and he promptly arranged a time to come and evaluate the project., measured, etc. Once we identified a door, Sean ordered it, and then lined up those on his 'team' to accomplish all the changing of the woodwork, moldings, painting, etc. Oh my goodness, Sean and his group are extremely reliable, they know that precision counts, and are experts in every aspect to get the job done with complete customer satisfaction. Sean is a professional that a home owner can trust
