"Jaime and his crew built a cedar deck and constructed a crawl space with access doors for my new manufactured home in Montauk. Great communication, the carpentry was well done and in the timeframe that was expected. Would use again for other projects"

"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."

"Nick did an awesome job with our medicine cabinets. His work went above and beyond. When he noticed too-large gaps between the doors and frames, he drove all the way to the building supply store to get better-sized parts. Would definitely recommend him."

"First, let me tell you that all of the 5-star reviews for this company and specifically Eddie are true. This young man is wise beyond his years, professional and displays a depth and knowledge greater than the 50-year-olds I work with. He consulted on product choices, guided us with samples, tested stains and visited us multiple times to ensure our project would be flawless. Who is this guy? Could all the hype be right? Our job started with an on-time arrival by Eddie and after reviewing the day's activities with us he set out directing his team to prep, tarp, protect and ensure our area would be as clean as possible throughout the job. He and his team stained pine windows, trim, molding and undertook a brand new custom Mahogany door with enthusiasm. It was a pleasure to learn about his craft, see him at work as he stained, sanded and re-stained our beautiful new door and sidelights. The woodwork was exceptional, the poly coat on the trim made our doorways and windows shine with just the right amount of gloss. In addition to doing a great job, they cleaned up every day before leaving. What a joy to have a pro care so much for his craft that he stayed a few extra hours to get the job done right. Bravo - He will be a fixture at our home for years to come and I'm so glad we found him."

"I highly recommend Loja Renovations & Fine Carpentry LLC! Manuel and Fabian were professional, courteous, and did an outstanding job. They helped me with several projects in my home, including mounting two TVs, installing a shoe rack, hanging a very heavy mirror, putting up window shades, and installing several shelves. Everything was done carefully and professionally, and they were extremely helpful throughout the entire process. What I especially appreciated was how prompt and reliable they were. They came all the way from Corona, Queens, and arrived ready to get everything done. Their attention to detail and quality of work really stood out. They offer a wide range of renovation and carpentry services, and based on my experience, I would absolutely hire them again for future projects. It’s not always easy to find people who are dependable, skilled, courteous, and take pride in their work, so I’m very glad I found Manuel and Fabian."

FAQs for addition and remodeling projects in East Hampton, 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.
