A local team that knows Essex County

Essex County is our home turf, and we know it well after years on its older homes, suburban additions, and busy storefronts. We work across the county every week, from the Ironbound and Forest Hill to Montclair, Livingston, Bloomfield, and the Caldwells, planning each job around the building it actually lives in.

  • Built for older homes

    From Newark brownstones, row homes, and multifamily buildings to early-1900s colonials in Montclair and Bloomfield, we plan for plaster walls, dated wiring, and tight access.

  • Permits and inspections handled

    We pull the required permits and coordinate inspections with each town's building department, so your project stays compliant and you stay out of the paperwork.

  • Homes and businesses

    Two- to four-family homes in the North Ward, single-family suburbs, and the warehouses, offices, and storefronts around Newark and Montclair too.

What our clients say

A 5.0-star rating from 40+ verified Google reviews across our residential and commercial work in Newark and Essex County.

"I hired Jeff and his team to build an addition on my house after considering several companies, and found his to be the most reasonably priced and well-prepared for the project. From start to finish, the team worked tirelessly, listened to all concerns, and made every requested accommodation. Jeff remained accessible and was very communicative any time an issue or question came up. The addition came out terrific, and I would highly recommend Ultimate Contractors Corporation to anyone needing work done on their home."
Chris Cooper
"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
"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
"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
"Phenomenal job from concept to creation and implementation. Solid and reliable work finishing on time, on target and on budget. Jeff helped me designed my kitchen. I was on the fence originally because my cabinets were not old. But once completed, I'm glad I replaced it. Definitely increased the value of the property."
Hai
"After getting multiple quotes, I choose Ultimate Contractors Corp. to replace my patio. I would highly recommend UCC. They were amazing. After I bought my house, I had an ugly backyard with lots of mosquitoes in the summer. I then decided to get most of the yard covered with concrete pavers. They came in and designed the area, helped me with color choices, and most important, they finished ON TIME! The construction crew was professional, clean and courteous. Again, I would highly recommend them for any home improvement projects you are considering. Great job guys, thank you!"
Joselyne Rivera
"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!!!"

Are you a licensed general contractor in Essex County?
Yes, we are a licensed, insured, and bonded general contractor holding NJ Home Improvement Contractor license #13VH12312800. We work on both homes and commercial spaces across Essex County and northern New Jersey.
Do you work on older Newark homes and multifamily buildings?
Yes. A lot of Essex County housing is older, from Newark brownstones and multifamily buildings to early-1900s homes in Montclair and Bloomfield. We are used to working around dated wiring, plaster walls, and tight access, and we plan for the surprises that come with older buildings.
Do you handle both home and commercial projects in Essex County?
Yes, we handle both. We do home renovations, kitchens, bathrooms, additions, basements, masonry, and concrete on the residential side, and office and retail build-outs, restaurant build-outs, tenant improvements, and warehouse work on the commercial side, all across Essex County.
How fast can you give me an estimate in Essex County?
We can usually schedule an Essex County walkthrough quickly and follow up the same business day. Call (908) 344-2984 or request a quote online and we will set up a time to look at your project.
Is the estimate free, and do you offer financing?
Yes, estimates are free, and financing is available so you can start sooner. We will walk your project, talk through your goals and budget, and put clear, transparent pricing in writing before any work begins.
Do you pull permits and handle inspections for Essex County projects?
Yes. As a licensed New Jersey general contractor, we pull the required permits and coordinate inspections with the local building department, whether your project is in Newark, Montclair, Livingston, or another Essex County town. We handle that paperwork so your renovation stays compliant from start to finish.
How long does a typical Essex County renovation take?
It depends on the scope. A single bathroom or kitchen often takes a few weeks, while a larger addition or full commercial build-out runs longer, and older Essex County homes can add time once we open up walls. We give you a realistic timeline in writing up front and work to finish on schedule.
