"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 have had several home renovations done over the years. I can honestly say that I have never seen such a high level of professionalism, courtesy and competence as I have experienced with Selective Remodeling. Mike, Joe, Scott and the entire crew offer a kind of customer service I've never witnessed. No question, concern or decision is overlooked or minimized. This recommendation comes at the very beginning of my kitchen remodel. Already, I'm blown away by Selective Remodeling and the phenomenal job done so far! Do yourself a huge favor and contact Selective Remodeling! You definitely will be delighted with your choice!"

"I used these guys for a remodeling job which included bathroom renovation, some minor electrical work, knocking down and installing new dry wall and painting. Class acts! We all hear horror stories about contractors not calling you back or not showing up on time or showing up at all. Not these guys! Hector, Moises and their crew really did exactly what they said they were going to do. Friendly, responsive and oh yea, solid work! Professional through and through! Highly recommend them and would use them again!"

FAQs for addition and remodeling projects in Bay Shore, 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.
