"I Highly recommend ALTA Renovation Corp. Their performance and track record exceed all expectations. This is the second large scale job, Jose Diaz and Crew were hired by us. I have been in construction (masonry) for more than three decades, so I’m no stranger to Home Improvements and ALTA by far was the BEST Quality of work performed. They handle all aspects of your work needed. No need to hold up the job because a Plumber or Electrician can’t be there for a week. They do it all, QUALITY work and at Reasonable Price. Jose Diaz, Owner of ALTA is compassionate to your needs and is approachable and understanding. Of course, the job scope changes whiles the job is ongoing, but it never an issue with ALTA. Back to my opening sentence, I HIGHLY RECOMMEND, ALTA, Jose Diaz and Crew. PS The Crew has been with ALTA for some time and they are extremely respectful. They all loved my family, grand kids and dog. ALTA is an 11 on a scale of 1 - 10."

"Jimmy was very professional. He helped with every step of the project including suggesting cabinet makers. He measured and ordered the cabinets for me. He was very flexible and responsive throughout the process. Whenever I was not happy with something, he was very responsive and did his best to correct it. I am very happy with the kitchen."

"We recently had our foyer completely transformed by Glenn and his crew, and I truly can’t say enough good things about the experience. From start to finish, the professionalism, kindness, and customer service were exceptional. What stood out most was that there was never any pushback, every idea or question was met with “yes, we can do that,” and Glenn always approached the project with patience, confidence, and genuine care. He was incredibly accurate with the project timeline, kept the workspace clean and organized every day, and was very conscientious about working in our home. His crew was professional, respectful, and hardworking throughout the entire process. Most importantly, the final result absolutely brought my vision to life. Glenn truly made my dream foyer a reality. The craftsmanship and attention to detail are beautiful, and you can tell he is extremely talented, knowledgeable, and takes pride in his work. We are beyond happy with the outcome, highly recommend!"
