Bill and Jose installed 5 large custom windows in our living room, a sliding door where there had been just a window before and replaced a bathroom window. The two of them worked nonstop, finishing the job in only 2 days. I was very impressed with the quality and craftsmanship of their work and so glad they cleaned up so well as they went along, at the end of the first day and again when the job was completed. The windows look awesome and we already notice a difference in how warm it is in our living room. We would highly recommend Custom Built to anyone looking for high quality windows and a company with some true craftsman. We couldn't be more pleased.
