My fiance and I had a great experience with Gary and William, who helped us renovate our new place in Harlem.  Gary took us through every step in the process: brainstorming, design, virtual 3D mockup, and, of course, the renovation itself.  He wasn't satisfied with the project until we felt that everything was 100% as we imagined it.  


One of the things that brought us to Gary is that we were looking for someone who could give us advice about design and function, rather than just completing renovations that we had to finalize beforehand.  We are very happy with our decision and there are several thoughtful touches that we wouldn't have thought of without Gary's input.  Gary and William are a great team, always available to answer questions or jump on a call and we always felt comfortable that our project was in good hands.

We had been looking at apartments for some time when we finally came to the realization that we were never going to find exactly what we wanted, so we decided to buy an apartment and renovate it to our liking.  Neither of us had experience with any renovation projects so there was a high level of anxiety around the whole process.  We met with several design/build contractors and finally decided on GEC Design who came highly recommended by our real estate broker.  Gary and Will were incredibly helpful and responsive and basically held our hand through the whole process.  We met on multiple occasions to ensure the design of the apartment was exactly the way we wanted, and Gary took us around to pick all the finishes from flooring and tile to appliances and bathroom hardware.  Will was able to provide a 3D rendering of what the apartment would look like so we could really visualize the space.  Inevitably, we changed our mind several times on certain parts of the renovation and Gary and Will were able to accommodate nearly everything we asked for.  Finally, we had some tight deadlines as we were trying to move out of our rental and Gary and Will moved mountains to get the apartment finished.  Now we are happily living in the apartment that we imagined and GEC brought to reality.

I had totally gutted my kitchen while I was away on tour and Gary/ William at GEC made sure that I was in great hands.  The FAST communication through the 4 month process was lighten fast and made sure every square inch of the project was done with detail and brilliance.  I loved working with them and this company....I highly recommend them.

Turning design into reality. From start to finish, we are here for our clients.

It was an easy and painless experience working with them. Gary and his team made what I thought would be a daunting project, very manageable! Managing the board and consistently following up to ensure we get the OK to start renovation! I think that was the most frustrating and long process but Gary and his team kept on it. Once we did get the board approval ( it was about a five week process), the timeline didn't shift all that much. Gary and his team were able to make up for the time without compromising any of the design elements or the craftsmanship. Gary and his team were on top of things. Whenever something went wrong in terms of a broken installation or the wrong lighting fixture being shipped, they managed all of the back-and-forth with the vendors.

Gary and his team totally transformed my tiny, outdated bathroom into a modern, spa-like bathroom. I'm so glad that I converted the tub to a walk-in-shower. Gary communicated with me throughout the whole process from design to execution. His team was reliable and they all worked with my building staff to ensure the job was done properly. Overall, they did a great job.

Gary has been a wonderful help for our personal residence. Since then he has been a part of several projects that our business has been involved with. We have always found him to be creative, dedicated and above all, very honest.

He has renovated 2 houses for us. In our Old Greenwich house, he turned our basement into a living space with bathroom. He designed and installed a new kitchen bar counter. He re-designed the living room and dining room by opening them up and made custom moldings. For our house in Greenwich, he came to the rescue when our finished basement flooded. He removed wet walls and insulation, installed a new floor and added custom made closets. He also converted our garage into an apartment with bathroom and mini bar. His design and space allocation for the open bedroom/living room was perfect. He expanded the space and installed sliding glass doors looking out on to the new patio. He designed a custom made book case with doors. He installed a small tennis court. Fixed our front stone wall and installed a white fence on top for more privacy. Custom designed a stone mail box and pillars with lights on top. He re-designed our guest bathroom and installed new toiled and wash basin and full length mirror and marble floor. In the kitchen, he removed a long wall and replaced it with a large window and relocated a cabinet. He helped me choose colors for every room in the house and installed custom moldings. He has a good eye for design and color keeping with the style of the house. He also installed lights outside and personally came by at night to ensure the lights were positioned correctly to illuminate trees etc.

I have worked with him on several projects located in NYC. From the filing of the job, through obtaining a C-O, Gary handled every aspect with the utmost professionalism ++. We have worked on gut renovations as well as just a quick update and modernization of multi unit property and apartments.
