Quick answers about windows and doors
What's included
Replacement and new-construction windows, plus front entry, exterior, storm, interior, and sliding patio doors. We supply the units or install yours, remove the old ones, flash and seal the openings, set everything level and locking, and finish the interior and exterior trim before we clean up, all under our licensed team.
Best for
Newark and northern New Jersey homeowners fighting drafts, fogged glass, high energy bills, sticking or rotted doors, or a tired-looking entry, who want weather-tight, energy-efficient windows and doors installed by a licensed, insured crew that finishes on time.
Typical timeline
A single door or a few windows is often a day or two once the units are in. A whole-home window replacement or several doors takes longer, and custom or special-order units add lead time. We give you a realistic schedule before we start and stick to it.

"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."
"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."
"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."
"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"
"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."
"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."
"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."
"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."
