"Jeff and his team recently completed two projects for us. First, they completely remodeled our master bathroom. This was a two-week+ project where they first removed our old bathroom, right down to the studs, and then expertly rebuilt every component of our new bathroom, including replacing a 40 year old bathtub with a beautiful new tiled shower. We are thrilled with our new bath. The second project they completed was to completely remodel our garage---floor to ceiling--- with new sheetrock, electrical, insulation, and paint. Early during this project Jeff discovered several electrical code violations, that he and his team then spent over a day correcting. This was unanticipated and required more work, although Jeff did not increase his price for the project. Throughout both projects we found Jeff to be very easy to work with and responsive to any questions or suggestions that we had. His crew was always on-time and kept the job site neat---cleaning-up at the end of each day. We are planning on having Northgate remodel our second bathrooom and replace our front door in early spring and would highly recommend Jeff and his team for any and all home remodeling projects. If you are looking for an honest, dependable, and experienced contractor that delivers the highest quality....look no further than Northgate Home Improvement!"

"Arthur gave us a fair and competitive estimate and was able to start work quickly thereafter. He and his team did an excellent job gutting and totally remodeling two bathrooms and a closet as well as redoing some of the wood flooring, moving vents, and moving hallways. Arthur himself was at the home everyday and did the important work himself. He also went the extra mile in helping us with small projects around the major project as they came up. He was extremely responsive in provided us with timely updates. When complications occurred (due to the house having not been renovated in 40 years) he was clear and helpful in keeping the project on schedule. He was extremely honest and I trusted him to be alone in my house for weeks on end with his team. I would/plan to work with Arthur again in the future for my home renovation projects."

"I hired Bob for our basement remodeling project and thatâ s the best decision we took. He is such a perfectionist with his job, gives right suggestions on what needs to be done, not at all money minded, and mainly manages work to be on time. He returned back to work immediately after his surgery just to meet the deadline. We are more than happy with the outcome. I sincerely recommend Bob for any work he is capable of doing and worth the decision. In fact, I kept pinging him for more suggestions even after the job is done and he is very responsive. So thankful that we were able to find Bob through my friend and he is a highly recommended person for any remodeling job."

FAQs for addition and remodeling projects in Commack, NY

The proper sequence of a kitchen installation starts with laying the foundation and structural framework. From there, you need to establish utilities like plumbing, wiring, and gas lines, then install cabinetry and countertops, and finally finish with flooring, painting, tile backsplashes, and lighting. A professional kitchen installation contractor can coordinate each component of your project to minimize the timeline and maximize resources.
