Your leased space, built out and ready to use
A tenant improvement in Newark, NJ turns a leased commercial space into one a tenant can actually use, from new walls, ceilings, and flooring to electrical, HVAC, plumbing, and finishes, anywhere from a quick refresh to a full white-box fit-out. Most landlords and business owners worry about the same three things. Here is how we take each one off your plate.
- Your business keeps running
We phase the work around your hours and seal off the dust, so you stay open and operating while we build.
- On time, as promised

The full price up front with no surprise change orders, plus financing to help you build out sooner.

"Had a really great experience with Ultimate Contractors Corporation on a new construction project. Everything went super smooth from start to finish, and the quality of the work came out even better than I expected. Jeff and the team are awesome to work with. They know what they're doing, stay on top of everything, and actually care about doing a good job. Communication was easy, they showed up when they said they would, and handled everything the right way. It's hard to find a solid, trustworthy crew, but these guys are the real deal. Definitely recommend them if you want the job done right."

"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 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"
