A local team that knows Sussex County

Sussex County does not build like anywhere else, and we know it well after years on its lake homes, older colonials, and main-street storefronts. We plan each job around the building it actually lives in, from the first walkthrough in Newton, Sparta, or the lake towns to the final cleanup.

  • Lake homes and older houses

    From custom lake homes around Lake Mohawk and Lake Hopatcong to older colonials and farmhouses in Newton and Andover, we plan for what your home actually needs.

  • Permits and schedule handled

    We pull the permits with your local building department and manage the schedule end to end, so your project keeps moving without delays.

  • Homes and businesses

    Renovations, additions, and decks for homeowners, plus build-outs for the shops, offices, and restaurants along the main streets of Newton, Sparta, and Franklin.

"I had a great experience working with this company. They were punctual, kept clear and consistent communication, and delivered high-quality results. The entire team was professional and efficient. Truly an exceptional team - I would definitely hire them again."
Joel Rivera
"Professionally done work and the customer service is just as good as the work done. Jefferson and his crew are experts in their craft and more importantly he will explain to you everything that will be done in the project, and will work with you every step of the way. He accepted a home renovation project of mine and I was impressed by the work done, even with the weather challenges he and his crew had to overcome. Overall 11/10 rating in quality of work, customer service, pricing, everything. Highly recommend to anyone."
Raymond Garcia
"Jeff and the UCC team have been absolutely great. They are very respectful, responsive and they have very fair prices. To start, the UCC team helped remodel my basement. I had a lot of questions about the style, design, color etc and Jeff had nothing but patience with me. He helped answer every question I had and provided great recommendations. In addition to doing my basement, the team helped hang up tv's in my living room and basement. They also helped replace both my front and back doors and install storm doors. Overall, Jeff and the UCC team are extremely professional, helpful, fair and do a phenomenal job. I strongly recommend them to anyone looking for great contractors."
Bodunrin Oluwo
"I cannot recommend them enought. I am a busy person with a family and I had a severe unexpected plumbing issue with my bathroom. I am not a handyman by any means. I started calling companies and they either stopped replying or wanted my to charge me crazy amounts. I was frustrated. I friend recommended me to this place and I am very thankful. They helped me right away and explained me all I needed to know about the price I was been charge. Specifically that guy tommy. He is a man of a few words. However, was really nice and professional. REALLY RECOMMEND THIS PLACE"
Holger Damian Velez Garcia
"After having a sudden water leak and having the whole house fall apart, I found the UCC team and Jeff was very professional from the very beginning. He was very attentive to everything that needs to be done and most importantly he understood my urgency and started working right away. Words can't even explain how grateful I am for the amazing work Yico and Patricio did. I am so happy with the UCC team and their work."
Ismot Tuba
"We are very happy with our Ultimate Contractors Corporation. Strong communication, fair price, quality work, a crew with great attitudes, and there was a clear intention to deliver a final product that exceeded our expectations. I highly recommend them. Thank you!!!"
Najib Moukarzel
"I had a good experience working with Jeff, Tomy and the UCC team for my bathroom remodeling project. From start to finish, their attention to detail were great. They took the time to understand what I wanted and provided valuable insights to enhance the functionality of the space while sticking to our initial budget. Even thought the project took longer than expected they were able to deliver the project with great quality. We are very happy with the results. I appreciate their customer service and their help. I would highly recommend them."

Sussex County questions, answered

Do you serve all of Sussex County, NJ?
Yes, Ultimate Contractors Corporation serves all of Sussex County, NJ. We cover the county seat of Newton and the towns around it, including Sparta, Hopatcong, Vernon, Franklin, Andover, Byram, Hamburg, Wantage, Stanhope, Hardyston, and Ogdensburg. Call us and we will come to your property for the estimate and the work.
Do you serve Sussex County clients up in the northwest corner of the state?
Yes. Sussex County sits in northwest New Jersey, and we serve clients within about a 45 to 60 minute drive, so the whole county is well within our service area. We plan our visits and crews around your schedule so the work moves smoothly, and we come to your property for the walkthrough, the work, and every step in between.
Do you pull permits and handle inspections in Sussex County towns?
Yes. As a licensed New Jersey general contractor, we pull the permits and coordinate the inspections your project needs, whether you are in Newton, Sparta, Vernon, Hopatcong, or any other Sussex County municipality. We handle the paperwork with the local building department so the work is done right and signed off.
Do you work on lake homes and older or historic houses in Sussex County?
Yes. Sussex County has plenty of lake homes around Lake Mohawk, Lake Hopatcong, and the smaller lakes, plus older colonials and historic farmhouses in Newton, Andover, and the rural townships. We are comfortable working with larger lots, weather-exposed lakefront exteriors, dated framing, and settled foundations, and we plan for the surprises that hide behind the walls of an older home.
Do you handle both home and commercial projects in Sussex County?
Yes, we do both. On the home side we handle renovations, kitchens, bathrooms, additions, basements, decks, masonry, and concrete. On the commercial side we take on retail build-outs, office and restaurant interiors, and tenant improvements for the shops and businesses in Newton, Sparta, Franklin, and the surrounding boroughs.
Is the estimate free, and do you offer financing?
Yes, estimates are free, and financing is available so you can start sooner. We come out to your Sussex County property, walk the project, talk through your goals and budget, and put clear, transparent pricing in writing before any work begins.
How do I get a quote for my Sussex County project?
Getting started is simple: call (908) 344-2984 or request a quote online, and we will set up a free walkthrough at your Sussex County property at a time that works for you. There is no pressure and no obligation, just clear pricing in writing.
How long do Sussex County projects take?
Timelines depend on the scope and the finishes you choose. A kitchen or bathroom often runs a few weeks, while a full renovation or addition takes longer. We give you a realistic schedule in writing before work begins and keep you updated at every step, so you are never left guessing.
