"No job to small or to big for Greg, they do a good job!"

"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."

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.

"Jose and his crew did an outstanding job on our extensive interior and exterior renovation, which included a new addition. The project covered everything from a new structural roof with shingles and skylights to new construction windows and doors, siding, a Trex deck, and fully renovated kitchen, bathroom, and laundry room. They also refinished a bedroom and installed beautiful hardwood floors. As with any large project, a few unexpected challenges came up, but Jose handled them with professionalism and kept everything moving forward smoothly. His craftsmanship is excellent, and he’s not only easy to work with but also patient and highly skilled at problem-solving. I wouldn’t hesitate to hire Jose again for future projects and highly recommend him to anyone looking for quality work and a reliable contractor."

"From beginning to end the process was flawless Let’s just start by saying not only was communication and follow up excellent, but unlike a number of contractors, Coco s team shows up punctually and on schedule. The work is priced fairly and done with skill and precision. My neighbors inquired about work on their home after seeing this company in operation. All work was explained and progress updates were provided. I’m totally pleased and would not hesitate to recommend them to anyone, and I have, and will continue to recommend them and utilize their craftsmen going forward"

"I had a new porch built and working with Ken and co, and they were outstanding from start to finish. The crew showed up when they said they would, kept the workspace clean, and treated my home with real care. They walked me through choices, gave clear timelines, and delivered exactly what they promised. The craftsmanship is solid and the porch has already become our favorite spot at the house. What stood out most was how easy they made the whole process. No surprises, no pressure, just steady communication and thoughtful work. I’d recommend them without hesitation to anyone looking for reliable, high-quality construction."
