Welcome to Chelsea Home Remodeling, Inc. A family owned and operated business since 1985, having 30 years of diverse experience, dedicated solely to residential home remodeling. The company was incorporated in 1986 by Dominick and Cynthia Mupo and sons, Michael and Louis. The philosophy of professional service combined with quality craftsmanship has proven to be the catalyst for our success. A key ingredient in the success of the projects undertaken is employment of a staff of diversified professionals. Almost all the construction activities are performed and coordinated by our full time staff. The company's original area of specialization, Custom Baths and Kitchens, have expanded over the years to include medium to large home renovations. An extended portfolio is available with qualified referrals upon request. Must have your own plans available for work to be completed.
"I was referred to Chelsea Home Remodeling by the owner of Marcor Roofing who previously did an excellent job on my roofing project. I was looking for a reliable contracting company to do a major interior renovation project including a full gut out demolition and rebuild of an existing extension that I knew required extensive corrections and repair. Chelsea is a family owned and operated business and they were exceptional right from the start. Dominick Mupo and his son Louis came to perform the initial inspection and to discuss my project. Dominick provided a very detailed estimate in writing, which he reviewed with me line by line in person with full transparency. They may not be the least expensive but I got what I paid for; they did a superior job from big to fine details from start to finish. Working with Dominick, Louis, Michael, Manny and Carlos was an absolute pleasure. They kept to the timeline, showed up as planned and on time, were pleasant and cooperative, cleaned up at the end of each and every day, respectfully cared for my home and property and were ever patient with my many questions and concerns every step of the way. They were consistently open to discussion regarding the problems found from the original construction, and with my participation in the process. They made the whole project as stress free as possible and consistently went above and beyond. I never doubted that my home and project was as important to them as their own homes would be. Their expertise with problem solving, knowledge of code and the correct way to do things, with acute attention to detail, was exceptional. Their referrals for floor refinishing and painting were also excellent. I am beyond pleased with the final results and could not have asked for a better contracting company. I will be using them for all my planned home remodeling projects and highly recommend them without reservation."

FAQs for major home repair (general contractor) projects in Port Jefferson Station, NY
A general contractor oversees a project from start to completion. They create the project’s timeline and schedule, hire, manage, and pay subcontractors and workers, and purchase and deliver building materials and supplies. They’ll also acquire necessary permits and HOA approvals, plan and execute necessary project changes, and make sure work meets quality standards.
Hiring an independent general contractor costs between 10% and 20% of your overall project cost, with larger projects incurring fees up to 25%. This fee covers complete project oversight, scheduling, and subcontractor management. The fee ranges from a few hundred dollars to tens of thousands of dollars, reflecting the full scope of the planned work and ensuring seamless coordination throughout the construction process.
General contractors typically provide estimates at no charge, but some may charge a small fee, especially for more complex projects. It's important to secure a written estimate, as it establishes a transparent agreement on project scope, labor, materials, and any additional fees. This helps protect you against unforeseen expenses and ensures clarity before the work begins.
When hiring a general contractor, you must provide an upfront deposit that ranges from 10% to 20% of your overall project cost. This deposit secures material orders, labor scheduling, and initial project preparations. An upfront deposit exceeding 50% is a clear warning sign and should prompt thorough contract verification before proceeding.
