"My husband and I are so happy with our new deck. Just in time for the beautiful weather! We have Jose Diaz with Alta renovations corp. to thank for making our home improvement job stress free. He and his crew were extremely prompt, meticulous, courteous and great communicators. Jose made me feel comfortable asking questions and was prompt to respond. It was truly an absolute pleasure working with them from the start to the finish !"

"Excellent job. Showed up on time and did a nice clean up after. This job was to replace a hole in the ceiling with sheetrock and painting. Very good work; I can't even see where he patched it, so smooth. I will definitely use James Agate Contracting again."

"Curtis is a real pro. I have used his services on two occasions and was completely satisfied. He installed a storm door, chair rail and molding. He shows up on time cleans up after he is finished for the day and ensures customer satisfaction. I plan on using his services in the near future and highly recommend him to anyone looking for a job well done"
