"Fabiano was a pleasure to work with. He was punctual when showing up to provide an estimate and to the project itself. He gave me accurate time lines and updates in real time when fixing my deck. After comparing 4 other contractors to replace my deck, Fabiano gave the best quote with no surprises and the estimate was spot on! I would absolutely recommend Fabiano for your next project"

"I recently hired Diamond Interiors to remodel my home, and I couldn’t be happier with the results. From start to finish, their team was professional, detail-oriented, and truly committed to delivering top-quality work. Every step of the project was handled with care, clear communication, and craftsmanship that exceeded my expectations. The transformation of my home is incredible—beautiful finishes, clean lines, and thoughtful touches throughout. They stayed on schedule, kept the workspace tidy, and made the entire process stress-free. It’s rare to find a contractor who combines skill, reliability, and pride in their work the way Diamond Interiors does. I highly recommend them to anyone considering a remodel. Outstanding job—thank you, Diamond Interiors! From Dan W."

FAQs for contractor service projects in Williamstown, NJ

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.
