A local team that knows West Caldwell
West Caldwell does not build like anywhere else, and we know it well after years on its mid-century ranches, split-levels, and older colonials, a quiet borough in the western corner of Essex County. We plan each job around the house it actually lives in, from the homes near the Passaic River up toward the Grover Cleveland Park line, from the first walkthrough to the final cleanup.
- Built for older homes
Behind a West Caldwell colonial or a 1950s ranch you often find dated wiring, plaster or lath walls, and layouts built two generations ago. We plan for all of it up front.
- Permits and inspections handled
We pull the permits with the West Caldwell building department and coordinate the inspections, hold the schedule, and keep you posted, so you do not have to chase paperwork.
- Homes and businesses
Single-family homes on both sides of Bloomfield Avenue and Passaic Avenue, plus the local shops and offices along those corridors.

"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!!!"
"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!"
"UCC have done various projects for my church in 2025. UCC is a reliable and dependable company. Detailed work and walks you through each step. Provides great suggestions when needed. I would definitely recommend UCC as a general contractor to handle all of your household/commercial needs."
"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"
"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."
"Jefferson and his crew did a fantastic job on my warehouse in Newark NJ. They are very reasonable and very clean. Highly recommend him and his guys for any type of repair work."
"Eric and his crew at UCC did an amazing paint job! The quality is outstanding, the lines are clean, and everything looks flawless. They were professional, on time, and left everything neat. I absolutely love the results and highly recommend them!"
"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."
