Garage Doors
Residential Garage Doors & Commercial Garage Doors
At T.M. Kenney Door Systems, we have long contributed to Long Island’s tradition of attractive properties and well-kept homes. Garage doors are our passion and we are proud of every project we have been associated with. With a huge selection of doors for all budgets and styles, we can supply and install the finest doors made of wood, steel, aluminum, and even composite materials.
We have experience with many garage door brands, but we recommend Garaga. From the knowledge acquired repairing garage doors over the last 50 years, we consider Garaga the most robust, providing the best protection against cold winds. Furthermore, Garaga does it with style, with an attention to detail second to none.
We welcome your visit to our showroom on North Main Street in Sayville where our experienced staff will guide you through the selection process for your new door. They’ll provide many alternatives for you along with free quotes. They can even show you what your next door will look like on your garage.
Garage Door Openers
Residential Overhead Door Openers & Commercial Overhead Door Openers
At T.M. Kenney Door Systems, we’ve learned that often, when your garage door fails to open, it is the door opener - not the door - that’s to blame. We carry a huge inventory of parts for many brands of electric openers. Our experience in trouble shooting a faulty operator is impressive and we will resolve the problem and get your door open if your car is stuck in your garage.
If you want to be safe and make sure your electric door opener will work flawlessly for many years, we can install a brand new LiftMaster Overhead Door Opener. They work smoothly and quietly, can even be opened during a power outage, and are able to be operated remotely from your smart phone.
See the full line of models available on this website, both for residential and commercial applications.

We had an old wooden garage door that had served us well but its time had come to be replaced. He explained all the details of selecting a garage door that would fit our needs. He came to our house to measure for the door and noticed that we had a structural piece of framing that was missing along the top of the opening. I corrected that right away. Glad I found that out rather than on the day of installation. Thank you Tom!

We needed our garage door replaced and we live in a condo complex so it need to match exactly and we needed it done ASAP. The door was ordered and installed in within 4 weeks. Brandon arrived the day of installation on time, introduced himself, went over the timeframe for installation and went to work. He was nothing short of polite and professional. He was done in less time then
Impeccable Service
Ordering the door was very easy. The installer was great. He worked neatly and efficiently. Very happy with our purchase. The door itself is beautiful and the operation is fantastic.
