Interviewed One Stop Improvements, LLC (ROC#289040) at the Maricopa Home Show. They gave the impression that no project was too small for them. I had a closet upgrade to add a shelf tower to two closets. They did not take the time to get a detailed drawing of what I wanted and since I was on a time schedule to get it done proceeded to agree verbally what to do. This was a big mistake, however, even worse was they did not want to work with me further to make any corrections. I would not hire them again and can not recommend them because of their unfriendly customer service.
