The Company

About JCH

The design-build company behind the custom homes, additions and renovations going up across Marlboro and Monmouth County.

Who We Are

Design-build, under one roof, in Marlboro.

The company was founded in 2022 by Carmine DiCosmo, who has had a 20-year career in construction management, general contracting, property management and civil engineering design. At JCH, design professionals are on staff who see the project through from the planning phase to final completion. This team has been growing for the past 15 years as a unit, and we determined we were ready to organize Juliette Custom Homes and begin a journey as a custom home builder. Our immediate network consists of fifty vendors who all know each other by face and name and pick up the phone on the first ring.

Handing your house to a contractor is a large leap of trust, which is why we run as a full-service design-build firm. From the first concept in the AI Showroom to the last sweep of a clean job site, one in-house team carries the whole thing. There is nobody to pass the buck to, and no corner worth cutting.

We don’t just build houses. We build the backdrop for your family’s legacy.

In His Words

Why the owner is on every job.

I didn't start Juliette Custom Homes to be the biggest contractor in New Jersey; I started it to be the best. I believe that when a family trusts you with their home, you owe them your absolute best. No shortcuts, no excuses. As an owner-operator, I am personally involved in every project we take on, from the first design consultation in our AI Showroom to the final walk-through. When you hire us, you get my word and my daily commitment to excellence.

If it isn't perfect, it isn't a Juliette Custom Home.

I hired Juliette Custom Homes to completely overhaul my backyard, including a new composite deck, paver patio, and fencing. From the very beginning, Carmine and the JCH team handled the entire process — design, drawings, zoning approvals, UCC permits, and the additional DEP permitting required because my home is located on the lagoon. The DEP approval process was not straightforward, and dealing with the town requirements and engineers became complicated, but Carmine knew exactly how to navigate the red tape. He kept everything moving forward and delivered a beautiful backyard that is fully permitted and compliant. As someone who lives alone and does not regularly take on major construction projects, I truly appreciated how easy JCH made the experience. Carmine presented great options, communicated clearly throughout the project, and the pricing was very fair compared to other estimates I received. I would highly recommend Juliette Custom Homes to anyone in Lanoka Harbor or anyone living on the water. Their ability to handle both the construction and the complicated permitting process made all the difference!

We have been working with Carmine and Juliette Custom Homes for years as one of their suppliers and it has always been a great experience. Carmine communicates well, stays organized, and keeps his projects moving. If an issue comes up, he addresses it quickly and works with everyone involved to find a solution. He is professional, easy to work with, and values good relationships with his suppliers and trades. 10/10 stars highly recommend!

We hired Juliette Custom Homes to extend and replace our deck with composite decking and PVC railings, and it was by far the best construction experience we’ve ever had. Carmine was able to help us modify the layout without needing an architect, handle the permitting process, and complete the entire project while we were away on vacation. Coming home to a brand-new outdoor living space was an amazing surprise! From start to finish, everything was seamless. Communication was excellent, the material selection process was simple, permitting and construction moved quickly, and the pricing was phenomenal. Carmine and the Juliette Custom Homes team made the whole experience easy, and we couldn’t be happier with the results!

These guys are A1. We bought our house back in October 2025. Over the course of the past (almost) year, carmine and the crew did a complete overhaul on our home. From the kitchen, to the bathrooms, to the new hardwood flooring and my wife’s long awaited arch ways! The guys handled everything with professionalism, knowledge and passion - exactly what we look for when finding a builder. Clean, honest and respectful. Great job guys keep it up!

Our flip came to a halt when the building inspector required a certified letter from an engineer regarding the roof structure. Carmine and Juliette Custom Homes handled it fast clear the issue and kept us moving. It was great to have him on our team!

Project Testimonials

Three projects, told by the owners.

Each family published their own scope and their own cost alongside the write-up. Their words, not ours.

The quality of the work is outstanding, and the experience exceeded our expectations in every way. Carmine not only kept everything on track against a very tight deadline, but also made us feel comfortable and confident throughout the entire process.
We hired Juliette Custom Homes to remodel our kitchen and living area as well as a furnace and water treatment upgrade and the experience exceeded our expectations in every way. We were working against a very tight deadline to have everything completed before the holidays, and the project also included a lot of detailed, custom elements that we knew wouldn’t be easy to execute. From day one, communication was excellent—clear, honest, and consistent. We always knew where things stood, what decisions needed to be made, and what to expect next. That level of transparency made a huge difference, especially given the pace of the project. Going into this, we definitely underestimated how hectic a renovation like this can be. There are so many moving parts, and it can quickly feel overwhelming. Carmine from Juliette Custom Homes not only kept everything on track, but also made us feel comfortable and confident throughout the entire process. We watched him push through some of the most difficult and high-pressure parts of the job with what looked like complete ease, which gave us a lot of reassurance. The quality of the work is outstanding. Every detail we cared about was addressed, and the finished space is both beautiful and functional. On top of that, their pricing was very competitive compared to other contractors we considered. When we look at the final result and the value it has added to our home, we can honestly say it was worth every penny. We would absolutely recommend Juliette Custom Homes to anyone looking for a contractor who does what they say they are going to do and make it look easy!

With over 30 vendors involved in our custom build, Carmine acted as a buffer between us and the many parties involved. Despite managing so many moving pieces simultaneously, the quality of workmanship and attention to detail have been exceptional.
We hired Juliette Custom Homes to build our new custom home after our previous house was lost to a fire. From the very beginning, having Carmine as our point of contact made an incredibly difficult situation much more manageable. His knowledge goes far beyond construction—he guided us through the complexities of working with insurance companies, local officials, and all of the moving parts that come with rebuilding after a loss. Juliette Custom Homes takes a disciplined, proactive approach to planning. Every phase of the project was thoughtfully advanced ahead of time, which led to seamless transitions once construction began. As homeowners with no background in construction, we especially valued how Carmine acted as a buffer between us and the many parties involved—including municipal inspectors, suppliers, subcontractors, and design professionals. With over 30 vendors involved in our project, that level of coordination was critical. The team was extremely accommodating to our requests and, just as importantly, completely transparent with our finances. We received weekly updates that tracked costs in real time, which gave us a clear understanding of where everything stood throughout the project. That level of organization and honesty built a great deal of trust. Despite managing so many moving pieces simultaneously, the quality of workmanship and attention to detail have been exceptional. From the outset, their pricing aligned closely with the actual cost of the project, which was essential for coordinating with our insurance coverage and forecasting expenses. The cost-plus structure also gave us the flexibility to make adjustments along the way and truly customize our home to our vision. We are incredibly grateful for the professionalism, communication, and expertise that Juliette Custom Homes brought to our project, and we would highly recommend them to anyone looking for a General Contractor for their future home projects.

Juliette Custom Homes made what could have been a disruptive project feel entirely seamless. We left for a trip, and by the time we returned the following week, our fully transformed outdoor space was completely finished and ready to use.
We hired Juliette Custom Homes to renovate our outdoor living space, where we wanted to expand and build over our existing wooden deck. From the initial visit, Carmine took the time to walk us through different options and completed all measurements and takeoffs on the spot. Within a week, the deck was fully designed, and his suppliers worked with us to select the right materials, making the entire process simple and efficient. Everything moved quickly, but we never felt rushed—just well guided. What really impressed us was the turnaround time. We left for a trip shortly after everything was finalized, and by the time we returned the following week, the project was completely finished. It was incredible to come home to a fully transformed outdoor space, ready to use right away. The quality of the work is excellent, and the entire experience was smooth from start to finish. Juliette Custom Homes made what could have been a disruptive project feel easy and seamless. CH combines their knowledge, expertise, and unrelenting will to drive a project to completion while delivering high quality workmanship. Their pricing was accurate and on par with other quotes that we received but they provided invoices and we saw what the actual associated costs were. We would absolutely recommend them to anyone looking to upgrade their outdoor living space.
