This is the third home we have renovated, the first with AGC. The company has far exceeded our expectations and surpassed every other company by a mile. It's almost like having an architect, builder and designer in one. We have even received top-notch expertise in terms of fixtures and furnishings. We cannot sing the praises of AGC enough! **★★★★★ — Valerie Redman, March 2021** > AGC had already come highly recommended. My experience with CJ Chumas and his team was amazing. They exceeded my expectations in every way. I purchased a home here in Montauk in desperate need of updating and TLC. CJ guided me through every aspect of the necessary repairs and improvements. Because of their professionalism and integrity I trusted them every step of the way as we of course encountered unforeseen problems. > CJ was respectful of my budget and offered creative and innovative solutions. I was truly impressed with his eye for design. > Thank you CJ and every member of the AGC Team who went about and beyond in making a dream come true. **★★★★★ — HU-405827336, Oct. 2020** > "It’s been 15 months since we moved into our new home in Montauk and we couldn’t be happier. Our experience working with Chuck Chumas and the AGC team was amazing. > > Chuck delivered in every way….on time, on budget, and total transparency throughout...but what stands out most was the pride and integrity every member of the AGC team have in the quality of their work….you see it every day, right down to the smallest detail. > > Chuck (along with our architect Bob Lenahan) was also very helpful in navigating us through the best materials to use for a seaside house and the extreme weather that comes along with it. Indeed as I’m writing this review the remnants of Hurricane Zeta are rolling through and you can hear a pin drop in the house….a testament to the high level of craftsmanship that AGC delivers!! > > We feel very fortunate to have worked with Chuck, CJ and the entire team at AGC...and to call them friends!" > > Matt T. > Montauk **★★★★★ — debw63, Oct. 2020** > After watching AGC Construction build the home next to our home, it was apparent that this construction company truly loves and is proud of the work that they do. Skill, and professionalism, would be 2 words that first come to mind to describe CJ from AGC Construction team. Our project was a deck and patio redesign in which CJ guided us through all aspects of the job –from navigating the permit process, creating a design that maximized our space, fabrication recommendations, and finally, an approved CO. CJ’s responsiveness to any of our inquiries was second to none and confirmed AGC Construction’s strong commitment to customer satisfaction. Many thanks CJ and AGC Construction and we look forward to working with you again soon! > Debbie & Bob Walley **★★★★★ — HU-103218176, Oct. 2020** > AGC was recommended through a family member. We had a full renovation of two bathrooms and 2 bedrooms. We could not be happier with the outcome. We worked with CJ who was very knowledgeable of the look we were going for. He and his team were very professional and paid attention to detail. With their expertise and great ideas our house has been updated beyond our expectations. **★★★★★ — mgengos, Oct. 2020** > These guys are really good! > I contracted with AGC to frame a new home project. As an out of town builder I needed a local company to do framing, carpentry, windows, etc. After meeting with Chuck and CJ from AGC, I was very impressed with their depth of knowledge and construction philosophy: employ state-of-the-art techniques and hire, train and manage excellent craftsmen. > I would hire these guys again in a heartbeat. **★★★★★ — HU-62776506, Oct. 2020** > AGC was referred to us by a friend whose custom house was built by Chuck and his team. We had a deck to re-build and some follow on projects like windows and doors which will likely lead up to an addition. Chuck treated us like he was building a whole house. His crews were on time, cleaned up daily and executed with excellent workmanship. Attention to details really matter to the craftsman who are on the job. I am always concerned about waterproofing / flashing details being done properly and after a few discussions I knew I was working with people who really know their trade. It was incredibly reassuring to see the trim and flashing be installed with perfection. For the first time in a long time doing a number of renovations, we are working with someone we can really trust to get the details right. Done right is the only way for AGC and they are certainly a pleasure to work with. **★★★★★ — HU-325379456, Oct. 2020** > I’ve used AGC for a number of different renovations on my home, and every time they exceed my expectations. I always look to them first whenever I need something done, because they have proven to me time and time again how trustworthy they are. Their standards and professionalism are the kind of standards and professionalism I try to imply in my own business. I highly recommend. I’ve used them from bathrooms, to windows, to the building of an accessory apartment. I refer them to everyone I know as I’m always confident putting my name behind them. **★★★★★ — d3llc, March 2018** > I hired AJC to perform carpentry work on a high-end residential renovation project in Montauk. Being in the construction industry myself, I have very high expectations. I can say without reservation that AGC is a top-notch builder. Their level of craftsmanship and attention to detail was outstanding. They provided an excellent level of supervision, and completed their work on schedule. I highly recommend AGC construction. **★★★★★ — Jim & Valari Beloyianis, Feb. 2018** > We hired Chuck and AGC to replace the exterior vertical cedar siding and all of our Anderson windows and sliders. His crew (especially Tom, CJ and Jon) exhibited the utmost of professionalism and completed the project in a timely manner. Chuck was very helpful in suggesting materials and solutions to make our 35 year old home in Montauk look brand new. **★★★★★ — Robert A. Lenahan Architect AIA PLLC, Feb. 2018** > I have had the pleasure of working with Charles Chumas of > AGC Construction on several projects in my hometown of Montauk, NY. > > Charles (Chuck) has very high standards for his company and sub contractors. Chuck has built successfully many beautiful custom residential projects. His attention to detail, construction management and subsequent paperwork is paramount in his field. > > I have professionally worked with Chuck on several projects over the years and have always enjoyed my time with Chuck and the fine craftsman that he oversees on each project. > I now call Chuck Chumas a good friend and highly recommend him for your next project. > > Sincerely, > Robert A. Lenahan Architect AIA PLLC > 379 State Street, Suite \# 2 > Portsmouth, NH 03801 **★★★★★ — dana\_granata, Jan. 2018** > Working with AGC construction was a pleasure. Chuck and team were helpful, approachable, had amazing ideas and worked with my husband and I to implement ours. We discussed with them our expectations and they made it happen. They have an amazing attention to detail, and they go to great lengths to make sure everything is running smoothly. This team is an absolute pleasure to work with from start to finish. > > Thank you for building our dream home! > > Dana and Carlo G ## Selected projects - [Montauk Beach House](https://www.houzz.com/hznb/projects/montauk-beach-house-pj-vj~2909230) - Location: Not specified - Photos: 8 - Description: This modern beach home was designed to maximize ocean views, featuring an "upside down" design concept, with communal living space and decks on the second floor. - [Montauk On The Lake](https://www.houzz.com/hznb/projects/montauk-on-the-lake-pj-vj~2919241) - Location: Montauk, NY - Photos: 13 - Description: An "upside down" concept home located on Lake Montauk.
