Our Services

Due to the towns rapidly changing codes and regulations, we work with a professional expeditor that handles all of the essential town requirements needed to complete your home renovation


We have an architect that is on call 24 hours a day 7 days a week. He works with the Carstan Family throughout the home renovation process from start to finish. Our architect will partake in meetings with the homeowner and a member of the Carstan Family to assist with the entire design process.


After the necessary permits are obtained, all of the crucial inspection are scheduled. A Carstan representative will personally handle all inspections to ensure all of the deadlines are met, and the job runs smoothly.


Top Quality Craftsmen    

Our Family has been working on Long Island for over3 decades. Throughout the years our company has had a consistent demand for the highest quality laborers that Long Island has to offer. With over 30 years of experience in this forever evolving industry our crews have been passed down from generation to generation with the rest of the Carstan Family. Over 85% of our crews started working for Carstan Construction out of high school with heir fathers. With that said, we have gathered the most dedicated, talented, and skilled craftsman that we could find to join the Carstan Family. “Quality is not expensive it is priceless.”
