I hired AGC 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 Chuck 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.


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!


I worked with Chuck Chumas to finish my basement in my house in Montauk, NY. I was not able to be at the house most of the time so I worked with him remotely. He made it so easy to work together remotely. We worked through the plans on site prior to construction beginning. Once construction began, he would keep me up to date on progress regularly. The project went very smoothly and was on budget. The basement turned out beautifully and really feels like it is as nice as the other levels of the home. All of the finishes were of the highest quality. I was extremely happy with how nice and spacious it turned out. I would recommend this company to anyone looking to build or renovate a home.


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.

As a family who moves frequently and prefers new construction, we have had the opportunity to deal with many home builders. Our most recent home has just been completed and built by AGC Construction. Dealing directly with the owners, Chuck, C.J., Tommy and the team, was quite an amazing experience. Their hands-on approach to construction set them far above other builders that we have worked with. Watching them perform with their team and paying attention to every detail was very impressive. They far exceeded our expectations. Our design had a complicated roof line and many difficult features. The AGC construction team handled everything flawlessly. Not only did they stay on budget, they delivered the house ahead of schedule and gave us more than we expected. Many thanks to the team from AGC Construction.
