"I hired Long Island handyman construction group to remodel a 400sf basement and bathroom in Melville. They were priced in the middle compared to other bids. I picked them thanks to their out of the box advice which saved me thousands of dollars. There was one problem with the plumbing which cost an extra 1800 dollars. The owner settled with me 50/50 even though it was a pre-existing issue. The project was started early and completed early. All mess was cleaned up and the crew was very friendly and fully aware. Very reputable guys and very easy to deal with. Thanks Moises and Eddy."

"This is the 2nd major project I contracted Art DeRosa & Co for. The 1st being 4 years ago a major living room/family room renovation which was hugely successful. That 1st experience led me to award Art (after several other competitive quotes) this 2nd and far larger & more complex project.
Overall it went well but this was a complicated project encompassing all the typical trades and expertise of building a new luxury house but far more complicated because it was a renovation performed while we were living in the home. Dust partition walls with wood framing had to be erected in several locations in the house which included temporary doors for entering and egress in certain areas of the remaining living areas of the house in order to protect the remaining house from dust and demolition , as well as, provide privacy for us during construction.
Experience, Experience, Experience and Professionalism, Professionalism, Professionalism are the hallmarks of Art DeRosa and company. He is a seasoned performer and pretty much seen it all. Art has such a vast amount of home construction experience in both hi-end and medium end homes that he can draw upon a wealth of knowledge in all construction disciplines to implement a fine finished result. As a former tool and die maker his penchant for hi-precision finish work yields highest quality appearances to things like moldings; trim; windows; doors; floors; etc. etc.
This complex renovation project lasted 7 months which was within the initial time estimate given at the beginning and Art DeRosa and team were here every single day, day in and day out, bright and early during that time frame. He did not start any other projects and stayed on the job day-in and day-out even when other sub-contractors such as plumbers and electricians were on the job site excluding his people from doing any other work. Art DeRosa and team were here every single day until final signoff.
I would not hesitate to recommend Art DeRosa & Co for any planned New House and/or House Renovation of any kind.

"My husband and I are so happy with our new deck. Just in time for the beautiful weather! We have Jose Diaz with Alta renovations corp. to thank for making our home improvement job stress free. He and his crew were extremely prompt, meticulous, courteous and great communicators. Jose made me feel comfortable asking questions and was prompt to respond. It was truly an absolute pleasure working with them from the start to the finish !"

"We hired Coco’s Custom Building on 2 separate occasions. We needed our roof redone and later decided to hire them to replace a dozen windows in our home. The owner Keith provided us with a great quote each time and was able to schedule the work right away. Any questions or concerns I had were addressed immediately which made the renovation go smoothly. I would definitely recommend Coco’s Custom Building and look forward to using them with my future home renovations."

"Absolutely, I’d be happy to help you out with that review! Here’s a glowing one for Tri Build Construction and Ray: --- I recently had the pleasure of working with Tri Build Construction, led by Ray, and I can't say enough great things about the experience. From start to finish, the work was absolutely fantastic. Ray and his team were the epitome of professionalism: they arrived on time, communicated clearly, and maintained a clean and organized workspace every single day. Not only was the craftsmanship top-notch, but the attention to detail really stood out. They took the time to ensure everything was done exactly as we envisioned and even went above and beyond to accommodate a few last-minute tweaks we requested. The final result was everything we hoped for and more. In short, if you're looking for a reliable, skilled, and incredibly professional construction team, I highly recommend Tri Build Construction and Ray. They truly deliver a five-star experience!"

"We recently completed an attached 2 car garage with finished space above, a large undertaking, and hired Christian with Nighthawk construction. My husband and I Couldn’t be happier with the results. His communication was top notch, always responding to our calls and texts quickly and keeping us in the loop and up to date with plans and progress. He was knowledgeable, professional, and an all around nice guy. He was able to troubleshoot effectively and helped us navigate the home renovation process. We really enjoyed working with him and are thrilled with the final results. The addition looks fantastic and he was able to do it all within our budget. We have recommended him to everyone and won’t hesitate to use him for any future projects."

"Ronald and his team were great. He was the first to give me an estimate and was the only one who went on the roof to inspect it. He gave me an amazing price snd was available if I had questions. His team came early (7am) and worked until the afternoon. I would recommend them to anyone and hope to use them again for more work on my home."
