Mario and his team at A-Z Nassau Construction were amazing and did a beautiful job on our extensive home renovation of 2 bathrooms, kitchen,and bedroom. I have already started recommending Mario to friends and neighbors. The craftsmanship was of high quality and everything came out exactly as we wanted . Mario paid close attention to details and even helped guide us on some decision making based on his professional experience. Mario was onsite almost everyday to the point were even my neighbors were impressed. He and his team were accommodating, professional, and thorough. When originally getting estimates, Mario’s was the most detailed and comprehensive out of all the ones we received. That attention to detailed carried over into his job and we could not be happier with the results. For any future projects, I will be calling Mario first!

Mario and his team did a fantastic job on our project. They installed a new kitchen, fully renovated a bathroom, installed new windows, and put in new lighting and plumbing across our entire apartment. They also surprised us with some very nice looking custom closets! Would absolutely recommend Mario for any contracting work that needs to be done to a high standard

Wow were we lucky to find this GC. We could not be happier with every aspect of our entire reno experience with Mario and his team. Working with them for weeks and they were on time, neat and clean, friendly, talented, attention to detail, and professional. We will call them again for every future need without a doubt.

Where do I begin?!?! My husband and I were looking for a qualified and reliable contractor to do some substantial renovations on our first home. Mario was one of the first contractors we met with, we immediately had a great gut feeling about him. Mario is extremely knowledgeable, genuinely charismatic, and very good at what he does. HE TOOK CARE OF OUR HOME AS IF IT WAS HIS OWN. We were not living in our house during the construction period and Mario made sure to keep in constant communication with us, updating us every step of the way. Our renovation included a complete remodel of our bathroom and fireplace, replacing all windows, repairing interior drywall and exterior siding, demolition of the wall between the living room and kitchen for open concept, demolition of the closet in the vestibule area to create a larger entry, replacing the front entry door, filling in the oak flooring where there were gaps and refinishing the flooring throughout the house. He also shifted our existing kitchen cabinets to the center of the kitchen to create and island and found a stone countertop for the 8ft island to match the existing stone by the sink. Mario has a great attention to detail and uses quality materials. As first-time homeowners, we didn’t know our left from our right when it came to a home – Mario was extremely patient with us and explained everything to us so we could understand. He went above and beyond for us in so many ways and we will be calling him back for any future projects we plan to work on. We highly recommend Mario to anyone searching for a contractor. Seriously, no need to look any further!! As my three-year-old calls him, “Mr. Mario”, is the best and was a godsend. Thank you, Mr. Mario for turning this house into our home!!

Mario and his team at A – Z Nassau Construction Corp. did a phenomenal job on our home renovation. The craftsmanship and attention to detail exceeded our expectations. We did a major gut renovation of our house (Kitchen remodel, bathroom remodel, replacement of all windows and doors, replacement of insulation and walls, interior paint, refinished floors, exterior house siding replacement, tile work and custom cabinetry) and they truly did an exceptional job bringing our visions of this home to life in a very timely manner. Mario is a man of integrity, he made himself available to us throughout the entire process. Communication with him was ideal, any questions or concerns we had we’re answered promptly. We could not recommend Mario and his team enough! We look forward to working with A – Z Nassau Construction Corp. for future home projects.

Mario and his crew replaced our roof and have helped us with many repairs and renovations around our house. Their work is extremely detail oriented and Mario is just a great guy. They are always so polite and take care to protect your floors and surrounding areas while working. If there is ever a problem, Mario shows up quickly to fix it and makes sure that you are satisfied.
