I hired Lioni Construction and Maintenance to modernize my traditional beach house, and they absolutely exceeded every expectation. They took my dated, classic-style home and gave it a fresh, beautiful modern look both inside and out that perfectly suits our lifestyle. The outdoor living space is now my favorite part of the house! Carmine suggested thoughtful upgrades including beautiful lighting and a privacy wall that created a stunning, functional, and private outdoor oasis. We went from a basic space to park cars to a true extension of my home where we love entertaining and relaxing. The quality of the workmanship is outstanding, and everything was completed on time. Thank you Lioni Construction for a wonderful transformation. I couldn’t be happier.

We have used lioni three times now for various services including construction and water drainage. Each time has been great. Easy to communicate with them; they are honest and great workers. Will continue to call them anytime we need anything around the house!

Amazing contractor and crew! Resourceful, respectful, hard working and reliable. They transformed our older house in a home sweet home. It was an extensive project and Lioni Construction tackled it very professionally. Project included: basement French drain and sump pumps installation, generator installation, addition of bathroom and walk in closets, gutting and renovation of older kitchen and bathroom, whole house floor refinishing and painting. We’re very happy and grateful to Carmine, Ali and crew for the great services and support provided.

Used many contractors in my life. Lioni construction is the most professional and honest company one can ask for. I had damage to my business and my home and Carmine and his staff spent countless hours getting my business and especially my home back to order. Their work ethic and reasonable prices are so appreciated. I will never even think of using anyone else to do any work for me. Thank you Carmine

Lioni Construction and Maintenance is a top-tier general contractor for kitchen remodels. I own a kitchen and bath design showroom servicing the Central NJ area, and Ali and Carmine have been outstanding partners to work with. They advocate for their clients, communicate clearly, and keep the project moving with a professional, organized process. On kitchen remodels especially, the details and coordination matter, and Lioni handles the sequencing the right way. They’re proactive problem-solvers, they don’t cut corners, and the quality of their workmanship shows in the finished space. It’s always a pleasure collaborating with amazing partners like Ali and Carmine, and I’m happy to recommend Lioni Construction and Maintenance to anyone looking for a reliable GC in Central NJ. I highly recommend.
