Chris hung a number of prefabricated doors and door frames that needed adjusting. He promptly provided us with a detailed quote and his availability. He did a job on a Saturday which was great as we really need this job to be done as soon as possible. The job was completed quickly, the adjustment to the doors are practically not noticeable and the doors and frames look great. Chris and his helper were very helpful and did a great job for us. Will definitely us Chris's services again.
