We found FCR Remodeling from a recommendation where we bought a new skylight. We were told that we would be so happy with their work that FCR would become our contractors for life. That was absolutely right!! They just finished our job and we love it. We had a new skylight installed, complete change of lighting in our kitchen, an archway in our dining room widened (which involved a new header) and lots of sheet rock repaired. I thought they were going to perform a surgery, the way they taped plastic around each of the work areas to keep the mess down. Meticulous, quality work, they showed up on time each day, and everyone was so pleasant to work with. Bill was easy to reach by phone, answered all our questions, and helped us figure out some parts of the job that were challenging. He supervised his crew and held everyone to very high standards. The only downside is that you will wait a long time for them to start your job because they are in such demand. We signed with them in May and began construction in September, but it was worth the wait.
