About Gary Courtier Home Improvements

Our Company

At Gary Courtier Home Improvements, we've been building, renovating and extending homes since 1993. In that time, we've learned many things, but one fact stands above all: A delighted homeowner is the foundation of our business. Customer satisfaction is the most important thing we build. From designers and architects to framers and finishers, we have all it takes to make your dreams come true. We respect the integrity of every project as if it were our own home.


When you hire Gary Courtier Home Improvements for your renovation in East Hampton, dormer in Mineola, new home construction in Syosset, siding/roofing in Manhasset or commercial project in Jericho, you can rest assured that there will never be any surprise costs during the building process. We understand the importance of communication. You will know who is at your home, when they will be there and when the job will be finished.


At Gary Courtier Home Improvements, we're more than a business; we're a family of fellow Long Islanders. We understand the importance of relationships and the power of customer satisfaction. Our "no hassle and no surprise" credo extends beyond our relationships with our clients and into all aspects of the construction process. Your job site will be impeccably clean and our crew will always be friendly, courteous and respectful - to your home and to your neighbors. We make the experience as stress free as possible.


Whether it's siding in New Hyde Park, a roof in Roslyn, an extension in Port Washington or a dormer in Syosset, every Gary Courtier Home Improvements project is treated with the same level of service and enthusiasm. We will work hard for you every day until the job is finished. And, at the end of each day, we leave your home clean, protected and secure.
