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."

"With catastrophic home repairs due to a water main break, it was amazing to watch the transformation. They turned the house into a beautiful home again.

Contractor services FAQs
Generally, general contractors charge between $50 and $150 hourly, though not every contractor charges by the hour. If charging based on the project, you can expect a markup of 10% to 20% of the construction cost. You can expect to pay between $300 and $500 daily if charged by the day.
General contractors are the ones that coordinate home construction projects. They are in charge of the day-to-day oversight of the subcontractors to ensure that the project is completed on time and to resolve problems as they arise. General contractors:
Complete pre-construction planning, both with the customer and crew
Provide realistic cost estimates
Develop construction timelines
Ensure deadlines are met
Acquire permits as needed
Purchase supplies and materials
Before hiring a general contractor for your home project, it’s a great idea to write down a list of questions to discuss with each prospect. Some example questions to get you started include:
Which types of insurance do you carry?
Can you provide a list of references?
What is the expected timeline for this project?
How will my project be supervised?
Will you hire subcontractors for the job?
What is the best way to communicate changes?
Will you obtain all of the required building permits?
While city and state laws vary on general contractor licensing requirements, hiring an unlicensed general contractor could lead to poor quality work, costly future expenses, and potential code violations. Be sure to check our state licensing tool to review the local general contractor guidelines for your area.
As you browse our pro listings, take note of the “Angi Approved” badge. Angi Approved businesses meet our standards for certification which include:
The owner, principal, or relevant manager passed a criminal background check
Required to have applicable state and local licenses
Maintain an average star rating of 3.0 or better on our network, if they have at least one review
Paying to advertise their services
Meeting any other eligibility criteria required by Angi
Keep in mind licensing is different from certifications. A license is a legal requirement to operate a business, while certifications are voluntary.
Yes, most general contractors require a down payment for project completion. A reasonable down payment for a contractor is 10% to 25% of the total project cost, though that will vary based on project size and location. The down payment helps cover the upfront costs of materials and permits and helps ensure payment for the project at hand.
