"We are absolutely thrilled with our new kitchen. Norman provided great design ideas that really increased the functionality of our space. The workmanship, attention to detail, and quality of materials was beyond our expectations. The team that came were very professional and easy to work with. We would definitely use Norman again for any remodels needed. We highly recommend him!!!"

"My Fiancé and I were in need of a major Kitchen remodel, that being said I had very bad experience when I had my basement redone, the contractor never finished the job and within less than a year what was done started to fall apart. What made that experience even worse it was a friend who was a contractor. Ok now the happy part comes, I went on home advisor to see what I could learn. I contacted Selective Sculptures they had great reviews and testimonials. First Dominic came to my home to see what needed to be done, we discussed our budget and how long it would take to complete. The next step we met at the design studio (mind blown he met me on a Sunday) his ideas were way better than mine we showed him our taste in colors and textures and he pulled off what I can only describe as amazing. Step 2 Dominic came back to the house with Anthony the GM and an entire crew I was speechless the lead plumber, carpenter and electrician went through every aspect with us it was quite an experience to say the least all this for only an estimate. I pulled the trigger if they were scamming me they deserved to get paid they were that impressive. Step 3 Dominic came back with his design plans again I was speechless he came up this a floor plan I one didn't think of or 2 thought possible. I agreed on the spot and was told work would start in 2 weeks and be done in 5-6 weeks. Well half way through what else does one do I was so happy I added additional work tear down the drop down ceiling in living room and do all the hard woods I had no idea I even had (bonus). I would speak to Anthony almost on a daily basis ( I'm sure he didn't love that ) but he was constantly making sure I was happy with progress and had answers for my questions never a let me check on that and not get back to me, in fact twice after I had a question within a few hours he would be calling me from my home so he knew exactly what I was talking about. Step 4 there's always a step 4 the basement's unfinished bathroom again above and beyond they gutted it out and did a total redo. I get a call from Anthony nearing the end as we never discussed color vanity or sink, he says do you trust me I said yes I do and that was the last we spoke of it until its completion he took a nightmare and made it a dream. Our house is now our home I couldn't in my wildest dreams be happier more satisfied or even fulfilled with how all the work was done the professionalism from the entire crew. I am only saddened by one thing and that's the feeling I lost 2 friends in Anthony and Dominic and that's a testimony to them and their desire to customer satisfaction. My name is David Hernandez and I live in Bay Shore NY and from the bottom of my heart I want to thank you SELECTIVE SCULPTURES."

"​I cannot say enough good things about Classic Remodeling! They recently completed a major project at my house—replacing the siding, fascia, and gutters—and the transformation is absolutely incredible. ​From start to finish, the team was professional, detail-oriented, and efficient. They didn't just fix up the exterior; they made my house look like a completely different home. The curb appeal is amazing now, and the quality of the workmanship is top-notch. If you are looking for an honest, skilled remodeling company that delivers outstanding results, look no further. Thank you, Classic Remodeling, for a job beautifully done!"

"Jose and his crew did an outstanding job on our extensive interior and exterior renovation, which included a new addition. The project covered everything from a new structural roof with shingles and skylights to new construction windows and doors, siding, a Trex deck, and fully renovated kitchen, bathroom, and laundry room. They also refinished a bedroom and installed beautiful hardwood floors. As with any large project, a few unexpected challenges came up, but Jose handled them with professionalism and kept everything moving forward smoothly. His craftsmanship is excellent, and he’s not only easy to work with but also patient and highly skilled at problem-solving. I wouldn’t hesitate to hire Jose again for future projects and highly recommend him to anyone looking for quality work and a reliable contractor."

"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."

"Blue Line Remodeling is truly one of a kind. As a holiday gift, I surprised my parents with a remodel of their two bathrooms and kitchen while they were out of the country. Bill, the owner, responded with a next-day consult, and despite a tight 3.5-week deadline, "Operation Secret Remodeling" was underway. Bill expertly guided the material selection, organized his amazing team (shoutout to Mike and Jose!), and kept everything on schedule. I even added flooring and 12+ new doors! Despite the extra work, they delivered on time, and the custom tiling in the kitchen was stunning. Bill and his team worked late nights and weekends to make sure everything was perfect. When my parents returned, they were in tears seeing their beautifully renovated home. I can’t recommend Blue Line Remodeling enough for their creativity, organization, and attention to detail. Thank you, Bill and team, for making this project unforgettable!"

"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 Smithtown, 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.
