"Greg & his team did a wonderful job on my renovation project, with exceptional marks for honesty and communication. Pricing was fair, and there was always confidence in the work itself: it's clear that Greg brought a tremendous amount of experience to the project, and he consistently ensured that work was done correctly (down to every last detail). I could not ask for a more reliable and honest person to deal with! Additionally, the scope of work changed on our project due to additional requests we had (our decision to re-do walls, install new lights, etc.) yet there was never any worry or concern on unfair pricing. Greg gets five-stars, and we will definitely work together again in the future."

"​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!"

"A long over due review. From the initial consultation to the jobs end. Extremely seamless. We had our kitchen remodeled and ton of extras we threw at him. Jose from day one was extremely professional from start to finish and takes pride in his work. So you can expect perfection on finish work. Alta gave us a fair priced estimate and a very detailed estimate of scope of work from start to finish. No surprise charges. The work was done in a timely fashion and completed on the timeline set forth. We were and are very happy with the quality of work and the professionalism throughout the project. Jose and Alta Renovations will be hired by us again to do our bathroom. I am attaching a link to the finish project below [*** Link removed ***]"

"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."

"Bathroom remodel went extremely well. Meet all of our expectations. Great communication during the whole project, and listened to all our needs! As usual with any construction project there are always some modifications to be made. US Home Remodel Team came through with those changes. Dealing with Bob and Steve was a pleasure. All workers were courteous, professional and on time. Also throughout project they were clean and organized. Would hire again!"

"Lou renovated my kitchen last year and I was completely satisfied. I called him back this summer to gut and remodel my bathroom. He was extremely considerate, and he treated my house as if it were his own. My house is small, and I only have one bathroom. The project took nine days. I was anticipating that there would be a big mess and a huge inconvenience. But even the demo was done very neatly and efficiently. Lou even took the time to re-connect the toilet each night so that I wouldn't be left without. Lou did an amazing job, and it was a pleasure working with him. Once again, I am pleased to recommend Lou for your kitchen or bath project."

"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!"

"I am thrilled I hired Joe. I had a 1970s bathroom that leaked. I never remodeled a bathroom and did not know how to plan it. He worked with me every step of the way to design the new bathroom. The shower was small but there was space behind the wall to expand it. We discussed the pros & cons of expanding it. Joe is very cost conscious. He made sure I got the best price for tile & floor. He even went with me to the tile store and negotiated the price down. He is a perfectionist and the tilework is beautiful. He takes pride in his work and pays attention to all the little details that made the bathroom look like it belongs in a mansion. I have now hired him to remodel the other bathroom & laundry room."

FAQs for addition and remodeling projects in West Islip, 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.
