I have been familiar with Castillo General Contractors for several years as they do work for a repeat client of mine and, based upon their workmanship, I have referred them. Over the past three days, I have used them myself, and I am EXTREMELY happy with their professionalism and quality of work! My current home is a “flip,” and the contractors who did the work did a really poor job! Castillo General Contractors re-did some of that work (re-hung closet doors that fell off, re-adjusted kitchen cabinets that were uneven (even pulling from wall), re-adjusted cabinet doors and drawers, and re-did poor drywall work! In addition, they power washed my deck and prepped and painted all shutters and re-hung (two of them) on my 3-level above ground townhome, repainted my front door and fixed my garbage disposal. I have seen complete re-models done by Castillo—wish they had done my home to begin with! I’ve used several contractors over the years and haven’t been excited about any of them for a multitude of reasons—until now! FIVE STARS, MAGNIFICENT WORK, HIGHLY PROFESSIONAL…VERY HAPPY CUSTOMER! YES, I RECOMMEND! Also, they were good on all areas listed above--on schedule, on budget, good workmanship, good communication, and organized...FANTASTIC!
