Expert Home Additions in Holbrook, NY

Greco Construction handles home additions for Holbrook homeowners who have outgrown their current layout. We work on the mid-century ranches, raised ranches, split-levels, and Colonials that make up most of the housing stock here in Suffolk County. Whether you need a new bedroom, a larger kitchen footprint, a family room off the back, or a dedicated home office, we plan and build the addition to match your existing structure. Holbrook homes often sit on generous lots with room to expand outward, which gives us real flexibility in how we design your addition. We coordinate the full scope of work, from framing and foundation to insulation, drywall, and finishing. Every addition is built to connect cleanly with your home's existing roofline, siding, and interior flow. If you are ready to add usable square footage without leaving the neighborhood you chose, call Greco Construction and tell us what you need.

Looking to the future, we wanted to make changes to our home for comfort and ease as we age. We hired Bobby Greco to replace our bathtub with a walk-in shower. And our basement washer and dryer with a stackable unit on the first floor. He did so much more! He transformed our bathroom into a high end hotel quality one. And he converted a storage closet into a hide away space for the stackable washer and dryer. With his offer of painting this second area, the result was a second room transformed! In the beginning we were very nervous and he reassured us that everything would be to our liking and beyond. With it being a one bathroom home we went away for the week. He kept us informed every step of the way. He not only gave us the bathroom of our dreams he guided us with practical as well as visual pleasing to the eye suggestions. The result is something we love and will have for the rest of our lives in our home. His personable and friendly manner made us feel like we were the only job he was doing. He was always available and welcomed our input and questions along the way. There are not enough stars to give an adequate review. We highly and wholeheartedly recommend him to anyone for anything!

Too bad there aren't "10" stars because I would have checked all 10! Magnificent, stupendous, unbelievable. These are just a few of the words that I could think of after I walked into my home for the first time after they were finished. All I could say was "OMG, I can't believe it." I must have said that a thousand times. I didn't think it was the same place and I still can't believe it. If you ever want to have some work done, please please please call Greco Construction, you will not be disappointed. From the planning to completion, every little detail will be covered. And you too will only be able to say, "OMG". Thank you Greco Construction for all that you did, I am ecstatic with the results!
