"We found REA Pro through positive reviews online. Jaime Rea was one of several contractors we interviewed. He is very prompt, energetic, and an excellent communicator. After an initial phone call and site visit, Jaime provided the estimate within a couple of days. The project – which included renovating 5 decks, repairing siding, and painting the exterior of the house – was started on time and completed within Jaime’s time estimate. His crew was very professional and personable and a pleasure to work with. We were really impressed with the quality of the work and their attention to detail. We are very happy with the final result, and would hire Jaime and his crew again for other projects."

"

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.

"Excellent! Alta Renovations did my bathroom from the studs out. Tile, sheetrock, floor, vanity and the plumbing and towel hardware. The job was was in a co-op, with very frustrating "rules" and "requirements ". Most contractors would not want to participate (paperwork, time schedules and parking restrictions). Jose, the owner of Alta, abided by all the rules, whiles still keeping a smile!!! His workers worked neatly and orderly, knew exactly what had to be done, and did it. Very pleased. I'm recommending him to all my ? ? ? ? ?"

"First, let me tell you that all of the 5-star reviews for this company and specifically Eddie are true. This young man is wise beyond his years, professional and displays a depth and knowledge greater than the 50-year-olds I work with. He consulted on product choices, guided us with samples, tested stains and visited us multiple times to ensure our project would be flawless. Who is this guy? Could all the hype be right? Our job started with an on-time arrival by Eddie and after reviewing the day's activities with us he set out directing his team to prep, tarp, protect and ensure our area would be as clean as possible throughout the job. He and his team stained pine windows, trim, molding and undertook a brand new custom Mahogany door with enthusiasm. It was a pleasure to learn about his craft, see him at work as he stained, sanded and re-stained our beautiful new door and sidelights. The woodwork was exceptional, the poly coat on the trim made our doorways and windows shine with just the right amount of gloss. In addition to doing a great job, they cleaned up every day before leaving. What a joy to have a pro care so much for his craft that he stayed a few extra hours to get the job done right. Bravo - He will be a fixture at our home for years to come and I'm so glad we found him."

"Excellent job. Showed up on time and did a nice clean up after. This job was to replace a hole in the ceiling with sheetrock and painting. Very good work; I can't even see where he patched it, so smooth. I will definitely use James Agate Contracting again."

FAQs for addition to existing structure building service projects in East Hampton, 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.
