"Greg & his team did a wonderful job on my renovation project, with exceptional marks for honesty and communication. Pricing was fair, and there was always confidence in the work itself: it's clear that Greg brought a tremendous amount of experience to the project, and he consistently ensured that work was done correctly (down to every last detail). I could not ask for a more reliable and honest person to deal with! Additionally, the scope of work changed on our project due to additional requests we had (our decision to re-do walls, install new lights, etc.) yet there was never any worry or concern on unfair pricing. Greg gets five-stars, and we will definitely work together again in the future."

"Hector and Moises were excellent! Hector came with one other of their crew and assembled my permanent gazebo. I have stone pavers and they were very careful in cutting them and digging Deep enough to establish a good anchor. They even installed railings for my back stoop. I would highly recommend them! Clean... affordable and professional."

"After several estimates and meeting with multiple contractors, we decided to move forward with this team and we do not regret it! They were thorough with the estimate, helpful with financing, and offered their recommendations on styles but weren't pushy. This experience was entirely catered to us and we genuinely felt taken care of. The project itself took longer than we expected, but the team did find some structural damage that needed fixing and, of course, any renovation typically takes longer than estimated due to unforeseen circumstances. The guys working on the house were respectful, clean and friendly, and were even great with our two dogs so that I never had to worry about anything. I felt totally comfortable with them being in our home every day. Roberto and Steven were incredible, and if you have a chance to request them, do it! They helped me understand every single thing they were working on and kept in constant communication. Not to mention, the work is clean and super well done! At the end of our project there was a mishap where someone forgot to put an appliance hose back in the drain pipe which caused our basement to get some water, but the guys came right back to the house and cleaned/fixed everything as if it had never happened. All in all, we would definitely use this team again and we are so grateful to have our dream kitchen."

"I first asked Jeff at Northgate to take out our old basement bathroom and build a new one 4 years ago. He did a great job for a reasonable price. He recently completed a total basement renovation and upstairs bathroom. Everything down to the studs. Again, did a wonderful job in about a month. He really deserves all the excellent reviews he has had. He always keeps you in touch and fixes any problems right away. We will be happy to have him do our kitchen soon. You will not find anyone better."

"I have never had the experience of remodeling a kitchen; and from what I had heard from people who did a remodel; it was a horrendous experience. I can truly say Homecraft(Norman) advised me through the entire process and I have nothing but positive feedback to give anyone who asks me. Norman’s staff of electricians and Dal his contractor were quite talented and professional. Overall I would highly recommend Homecraft for any remodeling project."

"

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.

"We have worked with Anthony from TAS Construction since 2006. He built a 2nd story addition on our home and completely remodeled the first floor. His work and crew are professional and courteous and you see right away that Anthony cares about his clients. After Hurricane Sandy destroyed the 1st floor of our home, Anthony was there to help us repair the water damage almost immediately. Fast forward to August 2020, and Anthony made time to give us an estimate for some recent storm damage in a few hours. He knows his stuff and has a great eye and ideas that look amazing when implemented. We constantly get compliments on our home and never hesitate to recommend him ."

"Memo and Abby are fantastic. The communication is exceptional in both clarity and attentiveness, and the work quality - from prep to the job itself to clean up - itâ s the tops. I engaged Memo to build/install and paint, finish, and wallpaper a double-sided wall with some mill work and moulding details. For the same room I also engaged him to purchase/hang/install a solid core slab door in an existing doorway. Though not a huge job, as a designer I was really keen to work with someone on the details - and Memo was so easy to do this with and delivered on everything I wanted. I will absolutely be hiring Memo again for more things and bigger jobs."

FAQs for addition to existing structure building service projects in Syosset, NY

You can typically raise your roof by four to eight feet, depending on your home's structure and roof design. The exact amount depends on factors like roof slope and framing support. Raising the roof creates additional interior space, enhances natural light, and increases your home's value. Consult a professional to determine the feasible height increase for your home.

Yes, you need a building permit to raise your roof. Obtaining a building permit ensures your project complies with local building codes and safety regulations. A professional contractor can assist with the permit and inspection process and ensure all legal and safety requirements are met. Your contractor will be familiar with building codes in your area, which can differ between cities or states.

While it's possible to raise a flat roof, it requires extensive structural modifications. Flat roofs lack the attic space and support structures of pitched roofs, so raising them involves significant engineering to ensure safety and durability. This process can be complex and costly, so professional assessment is essential before undertaking a project of this magnitude.
