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."
"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."
"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."
"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"
"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."
"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!"
"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!!!"
